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?

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.

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.

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!

Defend your borders

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.

Choose plants to deter cats

Image: Coleus canina (scaredy-cat plant) from Thompson & Morgan

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.

Avoid chemicals in the war against cats

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.

Try a cat scarer

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 perfect 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’

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 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!

Colourful flower displays

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. 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.

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.

Breathtaking Rosa For Your Eyes Only

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
Image: Dogwooddays

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

closeup of apple blossom from Dogwooddays Nic Wilson

Beautiful blossom on Nic’s espaliered apple tree is a great source of pollen
Image: Dogwooddays

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

Campanula medium (Mixed) from Thompson & Morgan

Pollinators love Campanula bells planted en masse in blues, whites and pinks.

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

Salvia 'Hot Lips' collection from Thompson & Morgan

Salvia ‘Hot Lips’ looks stunning when planted in swathes
Image: Salvia Hot Lips collection from Thompson & Morgan

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

Stock image of red and yellow rudbeckia

Pollinator-friendly annuals like rudbeckia are a striking way to fill gaps in borders
Image: Del Boy

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

Aster novi-belgii 'Dandy' from Thompson & Morgan

Michaelmas daisies provide a stunning food source right through until late October
Image: Aster novi-belgii ‘Dandy’ from Thompson & Morgan

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.

Clematis ‘Little Lemons’ – Very unusual long-flowering, dwarf clematis. Excellent in pots and hanging baskets.

We’re also pleased to formally announce our partnership with Sparsholt College Hampshire on their Behind the Genes garden at RHS Chelsea Flower Show next month.

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. Students at Sparsholt College have been involved in the design of the garden and have nurtured the plants that will be featured on the garden to illustrate various key milestones in plant breeding over the years.

T&M has long been at the forefront of plant breeding and can put its name to a number of key breeding breakthroughs over the years, such as Foxglove or Digitalis ‘Illumination Pink’ which won RHS Chelsea Plant of the Year in 2012 and which will feature on the Behind the Genes garden. Also appearing at RHS Chelsea 2019 is last year’s Plant of the Year winner, Hydrangea hybrid Runaway Bride® ‘Snow White’, and the amazing sunflower, Helianthus SunBelievable™ ‘Brown Eyed Girl’ which was placed third.

Part of the focus this year is also on our trainee manager, Lance Russell, who as an alumni of Sparsholt College, and now working at the forefront of the gardening industry, is the epitome of the new generation of inspiring and social media-savvy young gardeners. Lance is fronting our recent increase in film content on our website and YouTube channel and is set for a stellar career in horticulture. Lance can be seen in Thompson & Morgan’s video ‘Journey to Chelsea’.

What’s new in the garden?

new ideas in the garden

Are you stepping out of your comfort zone this year to try something new?
Image source: Tom Gowanlock

Are you looking for fresh inspiration? It’s easy to get stuck in the trap of repeating successful plants, flowers and crops year after year, rather than trying new things.

We caught up with a few gardening bloggers to see what they’re trying differently this summer. And as there’s nothing quite like learning from mistakes, we’ll catch up with them later in the year to find out how things went! In the meantime, check out these pioneering ideas to see if anything takes your fancy…

Mark of Mark’s Veg Plot is test-planting onions in bunches of half a dozen, rather than planting them individually, which is what he’s been doing up until now. The advantages? A saving of space, and no fiddly pricking out – but at the potential cost of smaller veg, as they don’t have quite as much room to spread out.

To be properly scientific, Mark’s also growing individual onions so he can compare results. He’s testing out the Ailsa Craig variety, which often grow into large, globe-shaped bulbs, so it’ll be interesting to see how they fare when planted so closely. We’ll find out later in the year!

Starting from scratch

Having moved house in 2018, Ronnie’s starting from scratch, and shifting her gardening habits to an allotment plot. It’s early days yet, but this Hurtled to 60 blogger has already established a cottage garden with a small wildlife pond, and is currently inundated with dahlia and sweet pea seedlings!

Determined to cultivate some food as well, she’s decided to set up ‘Christmas lunch beds’, where parsnips, carrots, beans, peas and more are growing. We look forward to catching up with her closer to the time to see how her festive feast shapes up.

Flowers and feasts

Dahlia 'black beauty'

Sally of Sally’s Garden Blog is always looking for new ideas, and her focus for the next season is very clear:

“I will be growing as much food [as I can] for my family and visiting wildlife this year.”

So root-bound fruit trees in pots have been finally planted out, and an old, plastic fish container is now home to dill, chives and marjoram – all perfect for a fish dish!

Much of Sally’s outside space consists of containers in a paved yard, which she moves around for variety. If you’re a container lover, take a tip from her and reorganise the space regularly. One new idea she’s kept from last year, though, is to grow Dahlia ‘Black Beauty’ again – there’s no point changing something you love simply for change’s sake!

Chickpeas and competitions

Richard at The Veg Grower Podcast is up for a challenge – and this year, it’s chickpeas! So far, the seeds have germinated, and are “growing into some rather attractive plants” – so he’s got his fingers crossed they’ll soon become something edible.

He’s also entered into a competition with fellow bloggers, Lee, Kirsty and Lucy. The rules are simple. They each have a vegepod, and all have to grow the same plants. The winner will be the gardener who manages to produce the most food – so it’s all down to growing techniques. We’re intrigued to find out what works best.

Are you feeling competitive? Perhaps your local gardening club has something beyond prize marrows to wager your green fingered reputation on…

A word to the wilds

Nic at Dogwooddays has a new mission on her to-do list this year:

“…adding holes in the fences and a gate for hedgehogs…

She’s also installed a selection of nest boxes around her garden to help a range of bird species find a good home.

The commitment to supporting wildlife doesn’t end there. She and her family are developing a wildflower area, along with a pond, and log piles for insects to inhabit. They’re even planting brassicas just for the large white, small white and green-veined white butterflies!

Having made the commitment to accommodate as much wildlife as possible, they’ll be surveying the biodiversity in the garden later this year to try and measure the success. You can follow their highs and lows on Nic’s blog, and we look forward to hearing her tips once they’ve had a chance to get everything up and running.

‘Behind the Genes’

It’s a very exciting time of year. RHS Chelsea Flower Show preparations are in full swing and the countdown is on.

This year, Thompson & Morgan is teaming up with Sparsholt College who are creating a ‘Behind the Genes’ show garden which is diving into the science behind plant breeding and genetics to offer an insight into the development of plant breeding and selection.

'Behind the Genes' Chelsea Garden

T&M breeding is recognised around the globe and it’s a great opportunity to showcase some of this in the garden which has been designed by Sparsholt’s Chris Bird in The Discovery Zone inside the famous Great Pavilion. The garden will feature plants such as Hydrangea ‘Runaway Bride’, one of the most floriferous and vigorous hydrangeas which won first place in last year’s Plant of the Year competition and plants from our very own breeding programme, such as Helianthus ‘SunBelievable™ Brown Eyed Girl’ which won 3rd place in last year’s competition. This is the world’s first multi branching sunflowers which puts out over 1,000 flowers during the growing season.

My first trip to Chelsea was back in 2014 as a student at Sparsholt when we brought home the gold medal for ‘The Paper Chase’ garden and it’s great to be going back again this year with both my college and Thompson & Morgan to work on this very exciting project.

It’s a real honour to be a part of this project which aims to encourage the next generation of horticulturalists whilst promoting the opportunities that I’ve enjoyed – particularly at such a prestigious horticultural event! I’m hoping that by being involved in this garden, current Sparsholt students will be able to see the career options that await them.

A very busy few weeks lie ahead; preparing plants for Chelsea comes with its challenges. I find it’s almost like tricking nature, as you have to learn to sweet-talk plants to make them look beautiful on the day! Various methods are used to encourage plant growth, and in some cases, it’s necessary to ‘hold the plants back’.

Of course, the weather has a big impact on how well plants progress and as with all years, each season is different and no one can predict the weather.

Peter Freeman, our New Product Development Manager, has been working miracles and we have got some very exciting Plant of the Year entries that are being nurtured as I write, including a really striking, brand new clematis which has flowers that change shape throughout the season. Clematis ‘Kokonoe’ starts with warm purple single flowers which change into fully double pom-poms blooms as they develop to create a truly luxurious display!

We are also really excited to be joined by plant hunter Peter van Rijssen, who manages the trials for a worldwide portfolio of new plants and an avid promoter on social media of plants and new genetics.

I look forward to seeing you all at Chelsea!

Happy Gardening,
Lance
