Did you know that the gardens at Chatsworth are being transformed? Have you always wanted to immerse yourself in the jungle at The Lost Gardens of Heligan? Visiting gardens is something of a national occupation for us Brits. And with good reason, because here in the UK we have some of the most beautiful stately homes, gardens, and parks to be found anywhere. To give you a taste of the best of the best gardens, here we present our pick of bloggers who review gorgeous gardens – enjoy.

A laburnum arch in full flower? You’ll have to time your visit just right if you want to see the one at the Dorothy Clive Garden in Shropshire. Garden, nature, and photography enthusiast, Susan Rushton just missed it in 2015, but saw it in all its glory this year – and has this beautiful photograph to prove it.

Think rhododendrons are a little too showy? Check out Susan’s incredible photography – she used to think so, but not any more. Her visit to this atmospheric garden proved to her that: “rhodis can be as ethereally lovely as any plant you’ll find in a shady spot.

The Green Fingered Blog

Abbey House Garden – clever use of planting makes the most of the ruin

‘Borrowing the landscape’ is a well known garden design trick, but they way it’s done here is cleverer than most.” So says Paul at The Green Fingered Blog. His visit to Abbey House Gardens in Malmesbury in Wiltshire just goes to prove how visiting professionally designed gardens can help provide the inspiration you need to get the most out of your garden at home.

At Abbey House, it’s the planting that leads the eye to the Abbey ruins next door that has Paul excited. And then there’s the use of focal points and the curve of the lawn. We can’t all live next door to a spectacular ancient ruin, but we can benefit from this blogger’s beautifully considered Abbey House Gardens masterclass.

Isn’t a peaceful retreat at the heart of a busy town centre, exactly what every shopper needs? In Farnham – there is just such a place. The Farnham Swimming Baths Trust is a charitable organisation that has created a truly magical garden from the town’s derelict Victorian outdoor swimming pool.

With mosaic hopscotch for the children, and for the adults, rose-covered arches and sculptures to enjoy – there really is something for everyone at the Victoria Garden. As for Pumpkin Beth – a self-confessed “gardening evangelist”, she grows the best organic pumpkins around!

Haarkon

It’s probably one of the most romantic names for a garden imaginable – The Lost Gardens of Heligan – in deepest, darkest Cornwall. They’re actually not that lost, according to India and Magnus of Haarkon – in fact they’re very much found. All the same, expect to discover “the closest we’ve been to an outdoor jungle in this country”.

Haarkon is all about celebrating “people, processes and the often-overlooked details of life”, and the result is a completely unique blog experience which features some truly incredible photography from all around the world. Thinking of making the trip to Cornwall’s most famous lost garden? Find out what lies in store right here.

Garden Visit

Take a stroll around a wildlife garden in the heart of Bedfordshire. The grounds of Sandy Lodge, the home of the RSPB, take the concept of bird-friendly to a level you won’t find elsewhere, and so they’re well worth a visit for anyone interested in tempting bird life to their patch.

Garden Visit is a superb resource for anyone interested in exploring UK gardens and parks – and has plenty of information about far flung botanical treats too. A site where you’ll find concise reviews along with opening times and directions, Garden Visit is a must for gardeners everywhere.

The Frustrated Gardener

Visit Cornwall’s Morrab Gardens to see sub-tropical plants flourish!

Walking towards Morrab House one passes through a damp glade filled with enormous tree ferns,” says The Frustrated Gardener, Dan. Morrab Public Gardens in Penzance are testament to the Victorians’ obsession with collecting, there being a sizeable ensemble of sub-tropical plants gifted by some of Cornwall’s most famous plant collectors.

Well worth a look if coastal gardening is your yen – Dan himself gardens a seaside plot in Broadstairs, Kent, and his own efforts are well worth a look. The highlight of Dan’s visit to Morrab? “Succulents, including the mighty Agave Americana, opuntias, aloes and aeoniums.

The Chatty Gardener

Get the lowdown on the Chatsworth House transformation. It’s a work in progress says The Chatty Gardener, Mandy, but you can already catch a glimpse of how it’s going to look when complete. These alterations will be the “biggest since changes by Joseph Paxton more than 200 years ago.”

Exciting times – the developments at the great Derbyshire estate are well worth discovering for yourself. Four new glades and a bog garden are just two of the planned works, says Mandy, a dedicated gardener and 2018 PPA Garden Journalist of the Year.

Looking for inspiration for your summer herbaceous borders? Take a turn around the gardens of Derbyshire’s Renishaw House with gardener, blogger, and writer, Kevin Gelder. Full of pinks, purples and blues, the Renishaw borders are “almost overwhelmingly beautiful”, crescendoing from the lawn-edge planting to the yew hedges behind.

You’ll also find a sparkling “white garden”, as well as a perfectly stunning hot border featuring nasturtiums, white buddlejas, roses and clematis. And before you leave, Kevin says, do stop to admire the statuesque lilies which, planted alongside roses, are a scent sensation not to be missed.

Carrots and Calendula

Ruined Nymans in its autumn splendour

How about some theatrical beauty? Overlooking the South Downs, Nymans, replete with romantic ruins, must be one of the loveliest gardens to visit any time of year. Catch it in summer for its blazing borders, or go there during the autumn when you’ll be rewarded with beautiful salvias offset against the flame colours of the trees in the background.

A serious fire ravaged Nymans during the late 1940s, but the family still live in the usable part of the house. A visit should include a browse around the second-hand bookshop and – of course – the plant shop. When she’s not visiting gardens, Ciar of Carrots and Calendula cultivates a sunny suburban plot in East Sussex.

The garden gate is open

Now for a “remarkable garden originally created in 1673 by the Apothecaries in which to grow medicinal plants.” When Julia, the blogger behind The Garden Gate is Open had a few hours to spare during a visit to London, she decided to call in at the Chelsea Physic Garden – four acres of calm in the heart of the busy metropolis.

Look out for beautiful woven sculptures by Tom Hare, a stunning collection of cacti, a fernery, and much more. And if you’d like to know more about the wonderful plantings at this historic garden, an audio tour will keep you informed as you wander. This blog is full of wonderful gardens to visit – take a look and you’ll discover some gems.

How to prepare your garden for a holiday

Car packed full of holiday luggage

Plan ahead to help your garden survive your summer holiday

You’ve invested blood, sweat and tears into your garden, so it’s perfectly natural to worry about leaving your plants while you enjoy a break from the day-to-day routine. 

We asked garden designer, Nic Wilson of dogwooddays, for her professional advice on how to keep things looking their best for when you return. Here are six practical suggestions to help prepare your garden before you go on holiday:

1. General care

Closeup of lawnmower and cutting grass

Cut and edge the lawn before you leave
Image: kurhan

I’m looking forward to some time away to relax with my family this summer, but at the back of my mind I can feel a niggling anxiety – how will my plants cope while I’m away? Will the lettuces bolt and the sweet peas set seed? How will the dahlias survive if there’s a heatwave? Last year we returned to find that wasps had devoured almost every greengage. Unfortunately, the whole crop was ruined.

To keep things tidy while you’re away, take care of a few general tasks before you leave. Weed borders and paths, and cut the grass in any areas that you’re not growing long for wildlife. Make sure that any top-heavy plants are staked to avoid high winds causing damage to stems while you’re gone.

2. Containers

Pots and containers in Nic Wilson's dogwooddays garden

Group all your containers together in a shady spot and provide automatic watering via an irrigation system. Failing that, sit the containers in trays of water.

Take down any hanging baskets and place them with your other containers in the shade. Terracotta pots dry out more quickly than plastic ones, so make sure they’re well watered before you leave.

3. Greenhouse

Ensure that your greenhouse plants have adequate shade and that the windows, vents and doors are open during the day. With a small greenhouse like mine, I leave the doors and windows open when we go away in the summer to avoid my plants overheating.

Water all your plants well and stand the pots on capillary matting so they can take up water slowly from the base reservoir. Plants can also be watered with an upside-down drink bottle with a drip end attached, or from a self-watering globe, or a mighty dripper.

4. Fruit and vegetables

Pick as much as you can before you go – our last job will be to harvest, eat and freeze our ‘Opal’ plums if they ripen in time. Ask a friend or neighbour to visit every few days to harvest crops so the plants will continue to be productive.

By thoroughly watering and mulching the beds before you leave, you can make sure that the soil stays moist for as long as possible. Protect your crops with specialist netting to avoid damage from pigeons and cabbage white butterflies.

5. Flowers

Summer-flowering plants like dahlias, sweetpeas, osteospermum and zinnias might be covered in blooms now, but these will have faded by the time you return and the plants will be starting to set seed. Although it might seem counter-intuitive, remove open and spent flowers before you leave and feed plants to encourage a flush of new blooms upon your return.

6. Biosecurity

Don’t bring back plant material back from your holidays, for the long-term health of your own garden and all plants across the UK. Diseases like Xylella have the potential to cause devastation to a huge range of cultivated and wild plants, so return with photos and memories, not with the plants themselves.

 

DIY Dahlia Festival

Dahlias at Anglesey Abbey, Cambridgeshire

It always intrigues me how different plants come in and out of fashion. Dahlias are one such plant that has ridden the roller coaster of popularity over the last century – but right now, they are definitely on the up!

I for one, am glad of their revival. So are the huge numbers of visitors to Anglesey Abbey’s Dahlia Festival, in Cambridgeshire each September.  I’ve visited on several occasions with my equally plant-obsessed friend who lives next door, with all kids in tow. In fact, it’s become a bit of an annual event for us all!  Each time these magnificent plants astonish me with their vibrant colours and huge variety of flower shapes.

It’s not just the plants that impress me. The gardeners that grow them to perfection deserve enormous credit, and the creativity with which they are displayed is breath-taking.

You might think that taking young children to a flower festival would be a recipe for disaster – I know I did. How wrong I was! In addition to the borders, many of the displays use cut Dahlia flowers placed into test-tube style vases. These can be attached to trees, inserted into lawns and displayed in all manner of other creative ways. It makes for a much more interactive experience which appeals to the children and grown-ups alike.

Dahlias appeal to young and old

Sadly we missed it last year, but as luck would have it, my friend was bequeathed an enormous number of rather large Dahlia tubers. They were unwanted by their previous owners.  Crazy, I know! So, it was decided … this year she would create our own Dahlia festival!

Dahlia tubers were potted up

©Sue Sanderson, Thompson & Morgan – Dahlia tubers were potted up in late spring.

The Dahlia tubers overwintered in crates in the greenhouse, and she planted them up into large pots this spring.  When they emerged from the greenhouse the Dahlia plants looked quite magnificent.  They were planted with care, watered well and given a good mulch of manure.  Sturdy stakes were inserted in the ground to support them as they grow.

Rows of Dahlia plants in the garden

On a side note, if you are wondering what the straw-like material is; it’s just a pile of dead weed and grass that was cleared from the site. When my friend went to remove it we discovered ground-nesting bees had made a home there.  Always keen to live and let live, the bees and their nest have been left well alone. These helpful little insects are under threat and need all the help we can give them.

However, there are other garden creatures, that we could well do without.  Slugs and snails thrive in our gardens, and unfortunately they have a particular taste for Dahlias!

With the Dahlia festival under threat, it was necessary to take sensible precautions! A combination of slug pellets and copper slug collars has been put in place, and so far there has been very little damage.

By September, there should be a fabulous display of dazzling Dahlias. Whilst not on the same grand scale as Anglesey Abbey, I’m certain that it will still be impressive.

Heavenly Hydrangeas!

If there’s one genus that I am utterly in love with then it’s Hydrangeas! Every year as we head into ‘Hydrangea season’ I begin muttering eulogies to these beauties… ‘What a stunner!’ ‘Isn’t it gorgeous?’ ‘Wow, look at the flowers on that!!!’

I don’t really know when my love for Hydrangeas began. I bought my first, Hydrangea ‘King George V’, many years ago and it still sits in a big pot outside my back door. Its performance always reflects the care (or neglect) that it receives throughout the year. In a good year it is fabulous, covered in white buds that open to reveal rosy, pink-edged blooms.  The flowers darken as they age to rich red-pink.

It’s always at its best, if it has been repotted in the spring and fed and watered liberally. Sadly this year it has been plagued with Hydrangea Scale and looks pale and chlorotic, with few flowers forming.  Scale insects suck the sap of plants, weakening their growth.

I’ve been squishing the white waxy clusters that cover the eggs whenever I see them. I usually leave the stems and flowers intact over winter, but this Autumn I will cut them all back to destroy any overwintering nymphs.  Fingers crossed for a better display next year!

Luckily, it’s better news on the other side of the patio where Hydrangea macrophylla ‘Madame Emile Mouillère’ is flowering her heart out.  I found her years ago on a visit to the nursery at Great Dixter Garden in East Sussex.  It’s funny how plants remind you of people and places that you’ve know, isn’t it?

 

Hydrangea macrophylla 'Madame Emile Mouillère'

This really is an elegant variety with large flower heads that open apple green and mature to dazzling white, before taking on a gentle pink tint to the oldest flower heads.

I’m rather excited about my latest acquisition of Hydrangea macrophylla ‘Princess Diana’. Now I know they look small right now – but given a few years of TLC they will produce fabulous double, pink flowers with an unusual star shape. I’ve only ever seen this variety in pictures so I can’t wait for the real thing!

My enthusiasm for Hydrangeas is being fueled by these two beautiful specimens on display here at T&M. Sadly I can’t tell you the variety as they are unlabelled, but there is no denying that they really are magnificent. One plant is so large that I asked my colleague, Sonia to appear in the picture for scale! Both are grown in large pots, and fed and watered liberally – it just goes to show how a proper care can make all the difference.

 

Spectacular Hydrangeas grown in large pots

You may have noticed that I haven’t included any blue Hydrangeas in this blog so far. The soil in my garden shows no hint of acidity! An acid soil will turn the blooms of most pink macrophylla varieties to varying shades of blue or purple.  I could pot a Hydrangea plant into ericaceous John Innes compost, water only with rainwater, and apply regular drenches of colourant… but I learned long ago that I’m rather a lazy gardener, so I prefer to work with what nature has given me!

It doesn’t stop me from admiring blue hydrangeas though. Here’s a stunning example from our ‘Your TM garden’ photo competition by this month’s winner, Diana Eastwood.

 

Beautiful blue Hydrangea flower

Hydrangeas really do have a lot to offer. Aside from the large, flamboyant blooms in summer, they also have lovely autumn colour.

In fact, I think they make the perfect gift plant. Here’s a double one that I recently gave for a friend’s birthday called Hydrangea macrophllya ‘Mademoiselle’ – I hope she gets as much enjoyment from Hydrangeas as I do!

How to stop cats using your garden for a toilet

Looking for ways to prevent unwanted cats visiting your garden?
Image: lkoimages

Fed up with neighbourhood cats fouling your flower beds, digging up seedlings, and damaging your plants? Potential solutions to the problem are many, but no one method is 100% successful, which is why it’s best to deploy an integrated anti-cat strategy. Think of yourself as a Monty battling the moggies, it’s time to plan an effective – non-harmful – campaign to rid your garden of cats. Here are some tried-and-tested options…

Secure your outer perimeter

Make your boundaries difficult to navigate

Make getting into your garden as awkward for cats as you can, and they’ll slink off to use someone else’s flower beds for their relief. Try stretching a string or wire a few inches above your fence line, or fix a band of soft, collapsible fencing to the top of your garden wall or fence – cats will find it tricky to negotiate these kind of hazards, and won’t be able to rest on top of your fence.

You might also like to try tacking chicken wire to your fence top, angling it away from your garden so cats will have to hang backwards if they’re determined to access your backyard. Do bear in mind, however, these kind of solutions look somewhat unsightly – you have to be pretty desperate to resort to them!

Border defences

Cats love to be comfortable while about their “business”, so make your patch as unpleasant as you can and, with luck, they’ll seek alternative arrangements. Cats hate the feel of chicken wire under their sensitive paws, so place a layer over your flower beds, cutting holes through which your plants can grow.

Alternatively, use a sharp gravel mulch, put down eggshells, sprinkle holly leaves, or place pine cones around the base of trees whose bark you wish to protect from cats’ clawing and climbing. Cats love dry, loose soil for their toilet, so water well and fill your borders with plants so they don’t have room to squat.

Plants to deter cats

Cats have a powerful sense of smell which you can use against them. By growing plants with strong perfumes that cats find distasteful, you make your garden a whole lot less attractive to feline visitors. Bear in mind that, just as some cats don’t love the smell of catnip, not all cats react to plants intended to deter them – but these are definitely worth including in your strategy:

  • Lavender – this garden favourite produces dainty purple flowers and smells divine to us humans. Bees love it and cats do not.
  • Rosemary – a kitchen staple, rosemary is a hit with pollinators. It prefers a sunny spot with well-drained soil.
  • Rue – once known as a medicinal herb, rue has bluish foliage and yellow flowers – grow with caution because rue is poisonous and physical contact can cause skin blistering.
  • Lemon balm – cats don’t like the smell of citrus and will avoid plants that smell of it.
  • Pennyroyal – with a powerful spearmint smell, this plant is an antiseptic, and an insect repellant.
  • Scaredy cat – specially bred as a cat deterrent, coleus canina smells horrible to cats and other animals but, provided you don’t touch the leaves, you won’t be able to pick up the whiff of dog urine this plant emits.

Chemical warfare against cats

Water around your flowers with a vinegar solution, or try heavily scented essential oils

Jeyes fluid and mothballs are often touted as effective cat deterrents, but they’re poisonous to cats and other animals. Natural options are a better alternative to using harmful chemicals to repel cats.

Try spraying white vinegar diluted in water – but be cautious – a vinegar solution won’t harm acid loving plants, but could potentially damage other garden plants if it’s too concentrated. That being the case, another option is to soak tea bags or cotton wool balls in vinegar and place them strategically about the garden – cats don’t like the smell and will avoid them.

Moggies are also dislike the smell of citrus and other herbal extracts – add a few drops of essential oils to your watering can. Citronela, lavender, orange, peppermint are all effective, especially when you use them in combination.

Cat scarers

Cats will avoid the high-pitched screech of sonic scarers
Image: Pest XT Solar Powered Ultrasonic Flash Pest Repeller from Thompson & Morgan

Sonic cat scarers are a proven technique for scaring cats away. When animals cross the sensor, these systems emit a high-pitched sound barely audible to the human ear but very uncomfortable for cats.

Unfortunately cats sometimes get used to the sound from a sonic system and learn to ignore it, others will ignore it from the get go; still others learn to walk around the problem, and foul other parts of your garden. Sound is one weapon in your arsenal, but it’s far from the whole deal.

Attack is the best means of defence

Cats and water don’t mix
Image: Pest XT Battery Powered Jet Spray Cat Repeller from Thompson & Morgan

Cats hate to get wet, and learn to fear the jet from a spray cat repeller. It works when the cat triggers a sensor, switching on a water spray connected to your garden hose – they’ll pelt for the fence as fast as their paws can carry them.

Cats make wonderful pets but when they use your garden as a public convenience, they’re a “purr–fect” nuisance. Hopefully these anti-cat measures will keep your lawn clean – if not, perhaps it’s time you resorted to the “nuclear” option – a dog.

 

Basil bonanza

Discover how to cultivate this fast-growing annual
Image: isak55

Early summer is the ideal time to sow basil seeds for late summer pizzas, salads and pasta dishes. In fact, professional garden designer Nic Wilson of dogwooddays says one of her favourite jobs of the year is collecting armfuls of basil leaves to blitz for pesto, filling her kitchen with the sweet, spicy smell of this fast-growing annual.

We asked Nic to share five of her favourite basil plants to grow from seed, along with some insider tips to guarantee success!

Five best basils to grow at home

There really is a basil to tempt every palate and suit every garden. Some of my stalwarts are chosen for colour, as well as flavour and aroma – including the sweet leaves of ‘Classico’, the dark purple foliage of ‘Crimson King’, and the liquorice aroma of ‘Siam Queen’. Here are my five all time favourites:

1. Basil ‘Pesto’

Although I’ve been growing basil to use in pesto for many years, this is the first year I’ve grown ‘Pesto’ itself. This variety has been especially selected to grow well in UK temperatures and has a strong flavour perfect for a peppery pasta dressing. Flushed with delicate purple, the leaves are carried on deep purple stems. The flowers are a pretty pale pink, so it makes a great ornamental choice too. Whether it’s grown in containers in a sunny spot or in the vegetable patch, basil ‘Pesto’ will add a touch of spice to any garden.

2. Basil ‘Lemonade’

The perfect addition to your glass of Pimm’s

This variety is high on my list to try next year. It has a lemon sherbet flavour making it perfect for adding to fruit salads and summer drinks, as well as adding a citrus tang to savoury dishes. Not all basil varieties thrive in the changeable UK weather – but ‘Lemonade’, like ‘Pesto’ is tolerant of British summers and can be grown successfully outside once the plants are established and hardened off.

3. Basil ‘Siam Queen’

This Thai basil is a wonderful ingredient for spicy curries and soups. We grow ‘Siam Queen’ in pots in the greenhouse alongside Kaffir lime, chillies and peppers as the base for summer Thai green curries. Slightly taller than sweet basil at 45cm, ‘Siam Queen’ has larger, more elongated leaves and a spicy liquorice flavour. A little goes a long way in salads, and it’s one of the best varieties for cooking.

4. Basil ‘Crimson King’

As soon as the tiny seedlings emerged, I fell in love with this basil. Not only does ‘Crimson King’ have a sweet flavour and softly cupped leaves, but the deep plum-coloured foliage means it’s a beautiful ornamental plant to grow. Some of my ‘Crimson King’ will stay in the greenhouse over the summer, but I’ll also dot some around the herb garden to add a splash of colour between my parsley and thyme.

5. Basil ‘Christmas’

Basil 'Christmas' from Thompson & Morgan

Basil Christmas is a new variety – a cross between Genovese and Thai basil. It’s another great addition to both edible and ornamental gardens with glossy foliage and beautiful spikes of purple flowers that are a magnet for pollinating insects. With a spicy mulled wine flavour, ‘Christmas’ makes a delicious pesto that can be frozen and added to festive pasta to bring a taste of summer to dark winter days.

Top tips for growing basil

Image: dogwooddays

Sow your basil seeds on peat-free seed compost and cover lightly with vermiculite or sieved compost. Water and place in a propagator or cover with a plastic bag. Germination should take around 14-21 days. When seedlings have developed true leaves, prick out into small pots and grow on. Eventually the basil plants will need to be potted on into 20cm containers. For outdoor basil, harden plants off over a 10-14 day period and plant outside after all risk of frost has passed.

Slugs and snails love to munch on basil seedlings, so I bring mine indoors at night until they’re large enough to withstand a little nibbling. Basil dislikes drying out, but also hates wet roots, so aim to water plants in the morning. Pinch out regularly to keep your growing plants bushy and vigorous.

A Tyranny of Pots

Seed Sowing

© Thompson & Morgan – Seed Sowing

Lately I’ve been thinking about this Plastics recycling issue; it’s really starting to bother me. Everywhere I look I see plastic pots, black ones, terracotta ones, grey ones, yellow, green, blue ones. The collective noun for pots is a stack of pots or a row of pots. I see it more as a tyranny of pots! Now, I admit that I am obsessive about order and like to ‘do the right thing’ but even I can lapse occasionally. If I try to sneak a plastic pot (or a dozen) into the black bin I am overcome with guilt. How can I preach the Recycle gospel if I’m not totally committed myself? I’ve tried leaving said pots on our front garden wall for neighbours to help themselves to no avail, in fact there is such a plethora of plastic pots (ooh alliteration) amongst us gardeners I’m surprised passers-by haven’t added their own! So what to do? Well, necessity being the mother of all invention I have become quite ingenious: 

  • I wash them all as I go along, then stack them by size and colour, oh yes, and shape, along the bottom shelves of my greenhouse.  We can’t have square pots, tall pots and round pots in the same stack, can we?
  • I’ve stopped (ish*) using plastic plant labels, opting instead for writing the contents of the pot onto the pot itself.
  • Once you start reusing the pots do remember to include the potting date each time and cross out the name of the last occupant; it’s surprisingly easy to mistake a petunia plug for last year’s osteospurmum. (* Of course, that won’t work on black pots.)
  • So I’ve been using the black pots up-turned in the bottom of large patio containers instead of crocks, much lighter and less soil used.
  • By cutting off the base of small pots you can use them as protective collars around juvenile tomatoes and cucumbers.
  • Ditto larger pots around border perennials to protect their early growth from slugs and snails. So far its saved my echinacea, lobelia and phlox from extinction.
  • If you sink a 9cm bottomless pot into the soil so that the rim is level with the soil surface, next to a cucumber plant, you can fill it up with water which slowly releases moisture towards the roots well away from the vulnerable neck of the cucumber.
  • This one is debatable, but sometimes it’s the only receptacle that comes to hand: if you stack two pots inside each other, then rotate the inner pot so that the drainage holes do not line up, you can use them as a scoop for soil or gravel. (Not vermiculite, that just flies everywhere!)
  • Here’s one I’ve just thought of: if you put a spool of twine in a pot and thread the end through one of the drainage holes you can use it as a dispenser.

Unfortunately, with a plant buying habit like mine, supply is always going to outweigh demand!

Anyway, here we are approaching the Longest Day. One minute it was March, I sneezed and when I opened my eyes it was June already! Fast forward T&M trial plants: (At least I was able to use up dozens of 9cm plastic pots for the plug plants.) I finally managed to integrate them all into the patio planting scheme, when, hey presto, a surprise bundle of experimental seed trials arrived! Always one to rise to a challenge, out came the seed trays and off we go again! Spaghetti squash, radish, tomato and lettuce, zinnia, ipomoea, nasturtium and sunflower – just a few then! (Lesson learnt: the later you sow seeds, the faster they germinate.)

Ipomoea are already planted in a tall Ali Baba pot to see if they will trail as well as climb. In the greenhouse the resident mice ate the first batch of lettuce and radish seedlings straight out of the tomato trough, second attempt in freestanding pots more successful. Sunflower seeds have been secretly sown in our next-door- neighbours’ front raised bed adjacent to mine, as a surprise for their young children. Squash are winding their way up an obelisk instead of along the ground as there’s no more room.

In the meantime, the first batch of trial annual bedding plants are starting to flower. Nasturtium Orchid Flame are truly gorgeous, wish I’d bought more! Petunia Sweetunia Fiona Flash had its first flower within a week of planting into its hanging bucket, looking very chic alongside a grey green hosta. Every day a new begonia or petunia surprises me.

Mixed progress with tomatoes Sun Cherry, Sungold and Sweet Aperitif. Sungold as always is romping away and has already produced flower trusses. Cucumbers Mini Munch are healthy too. They might even have a chance to produce fruit seeing as I’ve finally cut back all the enveloping ivy that was threatening to transform the greenhouse into a grotto. Let there be light!

Ipomoea are already planted in a tall Ali Baba pot to see if they will trail as well as climb.

Sunflower seeds have been secretly sown in our next-door- neighbours’ front raised bed adjacent to mine, as a surprise for their young children. Squash are winding their way up an obelisk instead of along the ground as there’s no more room.

But the one that is really challenging me is nicotiana Langsdorffii, what an absolute fiddle! Seeds the size of dust, I managed to prick out four tiny seedlings and grow them on, but oh so brittle. When they reached 8” tall, I planted them out in the central prairie bed, (with plastic pot collars and small stakes so that they wouldn’t be bullied by neighbouring thalictrum and calamagrostis) and then – it’s poured with rain solidly for two days. I haven’t dared go out there and see if they’ve survived. I saw them on display at the T&M Press Open Day show ground at Hyde Hall last summer and absolutely fell in love with them. You never see them as cultivated plants for sale so I guess this is the only way forward, fingers crossed.

When I do take a moment to enjoy the garden, it’s the roses that are taking my breath away. Rosa For Your Eyes Only has so many blooms it resembles the eyes in a peacock’s feather. I’m so enamoured with it that I’ve JUST HAD to buy its sister Eye Of The Tiger, which I’ve incorporated into the vibrant corner of the garden, red and yellow (most hated colour combination by my erstwhile embroidery teacher) with magenta echinacea purpurea, rouge lobelia Queen Victoria, (ooh, get me!) purple loosestrife. It’ll either look stunning or hideous, time will tell.

It seems slightly aimless not to be opening our garden for charity this summer, but oh the joy of not having to check the weather forecast every ten minutes, not to have to second guess which plants will be in flower and which will be over On The Day. In fact, I’ve had to wind my neck in a few times, not to be so goal orientated. I bet the plants are heaving a sigh of relief!

But it’s not all bucolic bliss. There’s the small matter of Hampstead Garden Suburb Horticultural Society Open Gardens Day for The National Garden Scheme. (Take a breath!) I may not be opening my garden, but as Assistant County Organiser for the Suburb, I’m responsible for 14 gardens, 4 of them new, and one allotment, all doing the honours for charity on Sunday 7th July. A village style opening in the heart of London. Oh, I could wax lyrical, but for full details please follow this link: https://www.ngs.org.uk/find-a-garden/garden/18140/

Perfect for pollinators

Give your garden a pollinator friendly makeover

Planting for pollinating insects has never been more important. As insect populations decline across the world, we need to find ways to help these essential invertebrates, for our future as well as theirs.

Gardeners can play a vital part in this recovery. With over 400,000 hectares of garden habitat across the UK, filling our gardens with plants that provide food sources for butterflies, bees and other pollinating insects can have a significant effect.

We asked garden designer, Nic Wilson of dogwooddays, for her thoughts. Here are eight simple suggestions to help make your outside space perfect for pollinators:

1. Add pollinator-friendly trees

Trees provide important sources of pollen and nectar for insects, especially bees, as they have many flowers close together. Flowering cherries like Prunus ‘The Bride’ and Prunus ‘Little Pink Perfection’ are ideal small garden trees, reaching two metres at maturity.

Fruit trees also offer masses of spring flowers and have the advantage of a delicious harvest. My family love the honeyed fruits from our greengage tree and we also grow several apples as cordons and espaliers. With a dwarfing rootstock and a trained form, fruit can be grown in even the smallest of spaces.

2. Consider flower shape

Choose cultivars with single blooms as the pollen and nectar producing organs in double flowers have often been transformed into extra petals. With single-flowered perennials like Geum ‘Totally Tangerine’, Geranium ‘Rozanne’ and Echinacea purpurea, you can fill your garden with food for native insects.

Growing different flower shapes such as bell-shaped (campanula, bluebells), tubular (heather, verbena), and flag (pea family) will attract a range of pollinators.

3. Plant in swathes or drifts

Insects use less energy if their food sources are close together, so planting in swathes not only creates a sophisticated effect, it also makes feeding more efficient. For a late summer combination, fill containers with a collection of salvias like Salvia ‘Hot Lips’, ‘Cherry Lips’ and ‘Amethyst Lips’.

Alternatively, plant intertwining drifts of Eryngium planum ‘Blue Hobbit’, Echinacea ‘Rainbow Marcella’ and Perovskia ‘Blue Spire’. The contrasting blue and orange tones will create energy in the border and the pollinators will love this late food source.

4. Fill gaps with pollinator-friendly annuals

Sowing annuals is a flexible way to provide a food source for pollinators as you can vary the mix each year based on which flowers are most popular with the insects. A few of my favourite pollinator-friendly annuals include: borage, calendula, Cerinthe major, snapdragon and rudbeckia.

5. Avoid chemicals

With increasing evidence about the effects of chemicals on wildlife, especially insects, we now know how important it is to avoid chemical control in the garden.

Use physical methods to control unwanted pests like squashing or dislodging aphids with jets of water, or using copper tape and wool pellets to discourage slugs. Try biological solutions like nematodes for slugs, vine weevils and thrips. Encourage ladybirds into your garden to eat aphids rather than reaching for chemical sprays. As Alys Fowler recently wrote in The Guardian: “these are chemicals that silence the soil.”

6. Think seasonally

Pollinators need food sources from early spring into late autumn, so plant with the seasons in mind. Spring flowering perennials such as lungwort, cowslips, honesty and flowering currant are ideal early nectar sources and autumn stalwarts like Michaelmas daisies, dahlias and sedum offer food when many other flowers have faded.

7. Create a herb garden

Planting herbs in a sunny spot is sure to bring in the pollinating insects. My lavender is covered with bees and butterflies in the summer months, while the chives, marjoram and thyme all attract pollinating insects and provide me with harvests for salads, soups and pizza.

8. Make a mini-meadow

One of the most exciting projects we’ve undertaken in the garden this year is to leave a small strip of lawn long and plant wildflower plugs to create a mini-meadow. Bare patches of ground can be sown with a meadow seed mix, but areas of long grass should be planted with wildflower plugs or container-grown plants. We can’t wait to see what pollinating insects are attracted to our mini-meadow later in the year.

By putting nature at the heart of gardening, we can enjoy the beauty of plants and animals working together in healthy ecosystems, knowing that our gardens are contributing to the wellbeing of the living planet that we all inhabit.

Thompson & Morgan Takes Third With Agapanthus ‘Fireworks’

Agapanthus Fireworks

We’re so pleased to announce that its Plant of the Year entry Agapanthus ‘Fireworks’ has been placed third today at RHS Chelsea Flower Show. It was one of six plants that we heard this morning were on the final shortlist of 20 entrants.

Agapanthus ‘Fireworks’ is a world first in pendulous bicolour agapanthus. Developed by Quinton Bean and Andrew de Wet of De Wet plant breeders, not only does ‘Fireworks’ offer better colour, it has bigger blooms and more stems per plant than previous bicolour cultivars.

This striking agapanthus flowers for longer too – most agapanthus are finished in August, but ‘Fireworks’ carries on flowering through September, giving gardeners 3 months of colour!

The large umbels carry generous clusters of upright white buds that open into fluted flowers which show off clearly-defined rich blue bases and white flaring petal tips. Plants are tougher than other evergreen varieties – staying in green leaf through winter in temperatures down to -10℃.

Peter Freeman, our new product development manager commented:

“We’re over the moon to have our Agapanthus ‘Fireworks’ placed in the top three of this year’s Plant of the Year. It’s a really great plant! We think gardeners will love its contemporary elegance and the fact that it can be used in so many ways in the garden. It grows to about 90cm so it looks really dramatic planted in drifts in the border, and just as good in patio container displays.”

All the plants that we entered into the Plant of the Year competition are featured on the Behind the Genes garden that was created in partnership with Sparsholt College in Hampshire. The garden, which is in the Discovery area of the Great Pavilion (Stand GPA154), offers a visually inspiring insight into the processes of plant breeding and explains techniques used to bring about improvements in plant species.

Also on the garden are our winning plants from last year’s Plant of the Year – Hydrangea ‘Runaway Bride’ which was placed first in 2018, and Sunflower SunBelievable Brown Eyed Girl’, which took third place.
