Where has this year gone?

by | Nov 3, 2015 | , , , | 1 Comment

Where has this year gone? I used to hate November as it heralded the onset of winter, but since taking up gardening I now feel anticipation as well as a gentle winding down. After a quiet October, November is back to business once again, as I am on the side of Autumn Tidy Up. I like to cut back early flowering perennials to show off the late bloomers. The greenhouse needs a jolly good sweep and rinse now that the tomatoes and cucumbers have all been stripped out, but with the chilli peppers still cropping prolifically, and a family of mice having taken up residence I am loath the disrupt the happy home. I have been able to sort out my seed packets though, allocating easy-to-grow annuals for our 2016 National Gardens’ Scheme Children’s Treasure Hunt prizes, salads for the greenhouse, veggies for the allotment and flowers for the baskets. At this year’s T&M Triallists’ Open Day in August we were given a wide variety of seed packets, some of which I have never heard of so I am looking forward to experimenting next spring.

winter cobwebs

I am wondering what to do with Fuchsia ‘Eruption’ (summer 2015 trial) – shall I take my chances and leave them in their pot in the shelter of the semi-enclosed patio, or shall I defoliate and prune them and overwinter them in the greenhouse? I have never been very good at getting half hardy fuchsias through the winter so we will see……. Begonia Apricot Shades Improved (summer 2015 trials) have mostly been lifted, their tubers drying off for storage, but there is still a glorious burst of colour from one last hanging basket.

Ironically, just as they say it will be the coldest winter for years (who are They incidentally?) I chose this summer to go salvia mad, from large leaved salvia involucrata, Black and Blue and Amistad, to the small shrubby varieties, having always avoided them as semi-hardy. Oh well, I have taken cuttings and will dig up the larger leaved specimens to overwinter in the greenhouse. I don’t have a propagator and the greenhouse is unheated so I have brought the cuttings into my husband’s heated studio workshop. To protect the cuttings from overnight chill I provide bottom heat by placing a hot water bottle between two seed trays, and sit the 9cm pots in the top tray!

late colour

Having cut back the geranium phaeum from around the apple tree I was able to tackle the ivy which had grown into the shrubs beneath. In the process I liberated two cornus Winter Flame (winter 2012/3 trials), their buttery yellow leaves and fiery stems bringing colour to a dark corner. Digitalis Leopardskin and Digitalis Illumination have only just stopped flowering amongst the pulmonarias, cyclamen, alchemilla and Brunnera ‘Starry Eyes’ (spring 2014 trials). I love gardening for shade, it’s so challenging and when you get it right so rewarding, all those contrasting foliage shapes, colours and textures.

contrasting foliage

Since we planted the Dahlias Fox Mixed and Trebbiano (summer 2012 trials) on the allotment this spring they have thrived as never before, as they are in full sun on well-drained soil unlike our semi-shaded clay garden soil at home, and the number of flowers we have cut has run into hundreds!

dahlias

 

Next year we will be adding some new dahlia tubers to the mix. The white cosmos and Californian poppies I grew from T&M seed in our sunroom this March are still flowering alongside, so I feel well encouraged to try annuals from seed next spring.

shady garden

So the gardening year has become protracted to ten active months, December & January being my hibernation period, with infrequent trips to the greenhouse to check on dormant plants and gaze longingly at the awaiting seed packets and trays in anticipation of early February sowing of sweet pea and the first bulbs emerging……. See you then!

Don’t be scared of growing trees!

by | Oct 28, 2015 | | 2 Comments

You could be forgiven for thinking there are only a few trees available to grow in your gardens. A quick walk around any neighbourhood sees the usual suspects; from birch to weeping willow; ornamental cherries to conifers!

 

Plus, trees can be thought of as huge specimens, which take over a whole garden. But, that doesn’t have to be the case; some trees are so slow-growing they’ll always stay compact, whilst others are genuinely much smaller, much like over-sized shrubs!

 

So, where do we start?? How about the tree that changes its clothes at least 3 times in the season? Cercidiphyllum, more colloquially known as Katsura Tree, is suitable for a small garden and will intrigue you with the way the leaves appear all along each branch! Those leaves also move from spring ruby red to summer fresh green to autumn burning embers! They also smell of toffee when crushed! I bet you can’t resist one now.

 

trees

 

Paulownia is another remarkable tree for the small garden, admittedly only when its coppiced (cut back to base each year), but in doing this, you’ll encourage huge, elephant-ear like leaves which look tres exotic! Grown as a full-sized tree, you’d also get to enjoy the foxglove-like, purple blooms, which give it the name Foxglove Tree.

trees

 

Now, when it comes to conifers, don’t consign them to the compost bin just yet! Just look at the Korean Fir, an enchanting specimen which makes a manageable tree for a small space. Super hardy and a holder of the much-coveted Royal Horticultural Society Award of Garden Merit too!

trees

Change your cherry tree choices too; ‘Amanagowa’ is a space-saving tree, with an upright, narrow shape, bearing sexy pink blossom every spring. Conversely, the Iford Cherry is a naturally weeping tree, which looks majestic in a container. Almost saved from extinction, the Iford Cherry was bright back to production from a single stem, taken from the terraces of Iford Manor!

So, now you’ve seen a few of the manageable trees available, maybe you aren’t so scared….??

Greenhouse Update

by | Oct 19, 2015 | , , | 6 Comments

Hello Everyone,

 

At the start of October T&M asked on their Facebook page, “What do you like best about this month?” There were many comments including my own, but thinking about it a bit more now, I have to say I think I like how you still have time to grow a few more seeds in the greenhouse before winter fully sets in. We have been so lucky here lately, it has not rained since September and it’s still warm enough to go outdoors without a coat. We have had no frost, and only had to have the heating on once or twice in the last two weeks in the evening.

seeds

I am so pleased that when I order seeds from Thompson & Morgan’s website it only takes a couple of days for them to arrive, this has meant that I have been able to make a start on my early spring vegetables. I have sown in the very first week of this month Cauliflower, Calabrese, Broccoli and Cabbage. I also had some left over pea seeds Alderman Heritage, Radish, Calendula, and Nigella, so they have been sown too. I was really surprised how quick the broccoli and cauliflower and radish germinated, I am still waiting for the Pansy, Godetia, Laurentia and Knifophoas to germinate from last month.

seedsAnother surprise I had was that some tomato seeds germinated in the borders of the big greenhouse. I have no idea what variety they will be. They were near the sungolds, so I am hoping it will be them. Mark has potted them up into individual two and half inch pots and they are in the small greenhouse as I am hoping they can be kept up heated over winter in there. I thought that when it gets colder I will wrap the pots in bubble wrap to keep the roots warm. I have no idea if this will work or not as I have never had tomato seedlings germinate in October, in a greenhouse border. I am usually very vigilant in removing all fruit, stems, leaves from the borders to prevent harbouring pests and diseases. The frustrating thing is that I was sent tomato seeds from Terri that arrived literally on the same day we found the seedlings. However, seen as I really don’t think the October tomatoes will still be alive next year as I am not planning on ever having a heater installedseeds in one of the greenhouses, I am really looking forward to growing Mountain Magic it’s specifically bred to be more blight resistant. Also I certainly won’t be putting in ten tomato plants it was too many for me to handle. I know next year six tomatoes will be the maximum for the big greenhouse and maybe three for the little one.

Just today we had confirmation that workmen are going to be painting our bungalow and replacing the external doors, so we have had to remove the hanging baskets and summer pots in readiness for them next week. So some plants that have been enjoying the summer sun have now had to be moved to the big greenhouse earlier than expected to ensure their protection. I have a load of Aloes, and Money Tree plant that need to be repotted, but for now they are sat on the greenhouse path waiting my attention.

We work full time so realistically most of the gardening is done on evenings and weekends, it’s getting dark quickly now, by seven the sun is almost setting, also the temperature drops rapidly once the sun has gone down. I may be lucky to hop into the greenhouses between making the next day’s sandwiches and cooking supper between five and six, but once the clocks go back and the weather changes I find it very difficult to go out in the cold and dark. Also I will be finding out in December if I am going to be having heart surgery or not, so I am planning to grow only what I can reasonably manage to look after.

In our small greenhouse we still have a continuous supply of spinach beet, I am really pleased as it’s a brilliant source of iron and it can be eaten raw or cooked. I like to lightly steam it, or sometimes just rip a few leaves into a stir fry. I recently found a recipe for spinach and pumpkin soup which seems ideal for Halloween. The carrots are starting to raising themselves out of the soil, on T&M’s website it says that with a bit of planning carrots can be more or less grown all year round, but they need protection from the worst of the weather.

seeds

Carrots take around twelve to sixteen weeks to mature and can be left in the ground until you’re ready to eat them. By growing carrots in the later seasons it reduces the chances of being destroyed by carrot fly. Carrot flies are attracted to the plant by oils released from the leaves or stems so it’s best to pull carrots in the evening.

seedsOn the shelves I have the baby veg seedlings, sweet peas, yarrow, Californian poppies and herbs. I also have empty plastic pots ready to transplant seedlings into. I have a collection of Christmas Cacti that need to be repotted after spending the summer under hot glass; they will be brought in and put on the bathroom windowsill where they will flower from November to January. I have a spider plant that I have no room for inside; it came from Dad’s so I don’t want to lose it, but I am not sure if it will survive the winter in the greenhouse. Finally, I will need to dust off the old blue bread trays for storing the begonia bulbs this winter. The begonias are still in flower so hopefully we don’t get any frost as they don’t look ready to die back any time soon. We usually leave the gazinas and dahlias in situ as although we have frosty days, it’s been at least five years since we have had a really harsh winter. In Pembrokeshire we tend to get west/south west winds or gales and an awful lot of rain rather than snow.

 

Whatever the weather there’s always something that needs doing in the greenhouse!

I’ll be honest with you, the last few winters I have tended to just pick the last of the produce in October, do a big tidy up, wash the glass down then shut the door until January when I start off the sweet peas. However this year it’s going to be different, it would be a sad sight if my new greenhouse was to remain empty for at least three months. There is a plethora of veggies that can be grown now from Brassicas to Onions and Shallots, and if growing food isn’t your thing, just think of how pretty your garden will be in the summer with strong bushy flowers such as fuchsias, dahlias, or or cannas overwintered under glass.

 

Until next month.

Happy Gardening,

Love Amanda X

Gear the Greenhouse

by | Oct 13, 2015 | | 1 Comment

Whilst the weather is still relatively nice and warm, and autumn days are still upon us, now is the ideal time to start preparing your greenhouse ready for winter. Come spring, there is nothing more nerving than having to clean a dirty greenhouse. Prepare now and in spring you can get started on sowing your seed without the mammoth task of preparing your greenhouse.

greenhouse winter

Firstly, clear out everything from your greenhouse, yes everything. That means plants, pots, seed trays and benches. As you are cleaning the outside it makes sense you do the inside too. Because days are becoming shorter and light is an increasingly valuable resource, removing the shade in your greenhouse will maximise the sunlight available to your plants. Ensure you scrub down all of the glass, paying particular attention to any restricted areas where debris such as leaves will collect and prevent water escaping from the roof. Cleaning the inside of your greenhouse with a horticultural disinfectant will remove any pests and disease lingering in the greenhouse, and prevent the spread in future. It is therefore essential that when moving your plants back into the warmth of your greenhouse, that you check them thoroughly for pests so you are not re-infecting your clean greenhouse.

Throughout the winter months, wash out pots and seed trays ready for spring sowing and planting. Don’t forget that you can still sow plenty of vegetables to grow in winter. Take a look at our ‘Top 10 vegetables to grow over winter‘ article.

Greenhouse heating

Greenhouse heaters will protect your tender plants from becoming a frosted, soggy mush, and keep your young plants snug and warm until spring. Heating your greenhouse will open up a whole new world of winter gardening!

For now, here are some top tips on insulating your greenhouse;

  1. Insulate with bubble wrap – A layer of bubble wrap clipped to the inside of your greenhouse frame will reduce heat loss and block icy winter draughts.
  1. Only heat the area that you need to – Heating a large greenhouse can be expensive and wasteful if you only have a few delicate plants.
  1. Don‘t forget to ventilate – One drawback of heating your greenhouse is the problem of increased humidity.
  1. Use horticultural fleece – On extra cold nights a layer or two of horticultural fleece will provide several degrees more protection to your plants without the need to turn up the thermostat.
  1. Use a thermometer – Invest in a good thermometer with maximum and minimum readings, and check it daily. By keeping an eye on the air temperature you will be able to use your greenhouse heater more efficiently and adjust it when necessary.

Don’t have a greenhouse? We have an extensive range of quality greenhouses online which will be a perfect addition to your garden when overwintering young plants.

New Lily ‘Romance’

by | Oct 6, 2015 | | 0 Comments

New Lily ‘Romance’ guaranteed to perform perfectly in patio pots

Trial and competition results prove new oriental lily will grow to perfection in any part of the UK – and maybe even Norway!

Lily Romance

Staff competition winner 2015

Here at Thompson & Morgan, we insist on full product testing before making new plants available to our customers. Much of this quality testing is carried out through technical field trials, but we also like to call on staff, customers and members of the press from all corners of the UK to get a better understanding of a product’s suitability to British gardens.

Ahead of launching Lily ‘Romance’ in the Thompson & Morgan 2016 Spring Catalogue, Horticultural Director Paul Hansord set staff and members of the press the challenge of producing the best patio pot of this new dwarf oriental lily.

From dry East Anglia and the wet Welsh Valleys in the west, up to the most northerly point of the UK – one thing is clear; Lily ‘Romance’ is a top performer no matter the local weather conditions.

“Every staff entry was a winner – in the end we had to award more prizes than intended”, said Paul. “Gardening in East Anglia poses a challenge when rainfall can be few and far between. Add drying easterly winds plus the extra challenges of container growing, and it proves this new compact lily will be a stand out hit for our customers in 2016.”

Terry Walton, gardening columnist and radio presenter, won the Thompson & Morgan media challenge with plants raised in his South Wales garden, less than 10 miles from The Vale of Glamorgan, listed by the Daily Telegraph as the third wettest place in Britain with an annual rainfall of 155cm (just over five feet!).

The lilies received a further accolade this summer when cut stems were used in the winning floral entry to the Unst Show, an annual flower and produce event held on the UK’s most northerly Isle.

Lily Romance

Writer and photographer Helen Harrison donated the stems to her neighbour for use in the competition. She said: “The latitude at which the lilies have grown is further north than St Petersburg, roughly on a par with Bergen in Norway and Stockholm, Sweden.  Unst is actually closer Bergen than Aberdeen!
“During the summer months, there is little darkness and during winter there is a much longer twilight around sunrise and sunset. No part of Shetland is more than a couple of miles from the sea and the salt laden winds are usually major inhibitors to plant growth, but not so with these lilies. They produced lovely flowers and won 1st prize in the show.”

The impressive results have left Paul and the T&M team confident they have the best performing patio lily on the market. Some oriental lilies are too tall for patio pots, needing stakes and supports. The Lily ‘Romance’ Collection will be available in the Thompson & Morgan 2016 Spring Catalogue at £12.99 for six 13/14cm mixed colour bulbs or £19.99 for 12.

 

10 unusual things to grow from seed

by | Oct 1, 2015 | | 1 Comment

There’s nothing more rewarding than growing from seed. That moment where you see the soil surface just breaking with a fresh green shoot is beyond magical! So if you now buy your petunias and geraniums as young plants, I suggest you challenge yourself, and explore the plant world with my list of 10 unusual things to grow from seeds:

 

The newest salad leaf, which I’m sure will be filling the salad bags in your supermarket very soon. Fresh, crunchy, rocket-style leaves with a spicy after-flavour! But, don’t worry, it isn’t as strong as the real thing! So easy to grow from seed, at any time of year, and ready to eat in just 4-5 weeks from sowing. Grow some on the windowsill, so you can devour some with every meal!

 

cucamelonThis diminutive little thing has so many different names; from mouse melon to cucamelon to mini watermelon and even Mexican sour gherkin! The vigorous plants are great for screening or patio obelisks, and are decorative in their own. But, take a peek beneath the leaves in midsummer and you’ll spy the little striped fruits, which only reach the size of a large olive and has a cucumber flavour!

 

 

  1. bananaBanana (Ensete ventricosum)

If you’re a little bit impatient, then you should to grow a banana! Each plant will put on rapid growth and appears quite lush and exotic. With the right care, plants can product fruit in the UK too! Fun to grow from seed, you’ll feel all tingly from the moment that first over-sized leaf bursts through the soil!

 

  1. Bird of Paradise (Strelitzia)

birds-of-paradiseConversely to the banana, you’ll need a lot of patience for growing a Strelitzia! The journey from germination to flowering can take up to 7 years… Similar in appearance to a banana, but a bit more leathery, the Bird of Paradise makes a talking point in a conservatory and once that iridescent flower appears, you’ll want to invite all your friends round to have a look!

 

 

hensol-violet

  1. Meconopsis betonicifolia Hensol Violet

The flower colour of this unique Meconopsis just cannot be described; it is metallic and shimmers purple or blue, depending on which direction you look at it from! A connoisseur’s choice of plant; perfect for damp, shady corners.

 

  1. Nasturtium Phoenix Mixed

nasturtiumImagine a ‘garden-friendly’ Nasturtium and you have ‘Phoenix’! Smaller growth than the usual giant cabbage-like specimens, and the flowers are super decorative, with a serrated appearance, and in the case of yellow- FRAGRANT! Don’t forget, pretty much all parts of Nasturtiums are edible too, so jazz up your summer food plates!

 

 

carrot-purple-sun

  1. Carrot Purple Sun

Bump up your antioxidant intake with the only fully purple carrot! Purple Sun is purple right through to the core; in fact, it doesn’t look anything like a carrot! Simple to grow, really fun for kids and imagine what you could make with it; purple julienne carrots, purple carrot cake, and so on…

 

  1. Sweet Pea Turquoise Lagoon

sweet-peaAnother glorious metallic flower, it’s hard to believe that Turquoise Lagoon is actually a reject from a breeding programme! The delicate flowers are iridescent, with mauve, blue and pink featuring. This is the start of some very different colours for the sweet pea family, so keep your eyes peeled!

 

 

 

  1. flower-of-deathLisianthus nigrescens

Err.. sometimes called the ‘Flower of Death’, this cheerful Lisianthus is actually an amazing seed to be able to get your hands on, as it’s the blackest of any known flower! This plant is just all about the drama; would you believe it’s way more than a metre tall too; think Nicotiana sylvestris, but black!

 

  1. Bat Plant (Tacca)

bat-plantThis one has to be seen to be believed! Again, superb, beguiling black flowers and- when you look up close- the blooms do actually resemble a bat as well! Not only that, you’ll love the vinyl-esque shiny foliage too! A nice little challenge to grow from seed!

 

Top 5 flower seed varieties

by | Sep 23, 2015 | , | 0 Comments

Michael Perry gives us his top 5 flower seed varieties:

Cosmos Xanthos

cosmos seed

For many years, the YELLOW Cosmos has been a myth, and indeed a variety did exist. However, it never flowered until almost September, which is no good for home gardens! Then, from nowhere, Dutch breeders came up with Xanthos, an acid yellow Cosmos which didn’t just flower from June to September, but also offered a shorter, branching habit, with more flowers than you’ve ever seen on a Cosmos! Top tip, grow it in patio pots for a show stopping display.

Zinnia Zinderella Peach

zinnia seed

Zinnia have also changed a lot over the years; evolving from a Californian annual which thrived in hot summers to a versatile annual that can now put up with the English climate! The Zinderella Series is a work of art as well, as the crested blooms shimmer with peachy tones, punctuated with hints of lime green. Zinnia can be used as a cut flower too, lasting an impressive 2 weeks in a vase!

Eschscholzia XL Yellow

californian poppy

Californian Poppies will literally thrive on neglect; requiring hardly any water and putting up with baking sun all day long! We selected this beauty for its large, frilly, bright flowers. As a hardy annual, Eschscholzia are a simple ‘throw and sow’ specimen, so you can scatter the seed straight outdoors where they are to flower!

Nasturtium Cream Troika

Nasturtium seed

The perfect hanging basket Nasturtium, with restrained growth and a gently tumbling habit! Easy to grow by sowing the seed directly into the basket, this has the potential to be the easiest hanging display you’ll have ever grown! Cream Troika is a beaut, with buttery yellow dotted blooms and icy variegated foliage.

Phlox ‘Cherry Caromel’

phlox cherry caromel

Who’d have thought something so beautiful would be so easy to grow? This startling little Phlox can be sown directly outside! You won’t be able to resist the fantastically rich caramel flowers with vibrant cherry centres! I don’t expect stock of this one to stick around for long though, so be quick!

 

The Chilli Challenge

by | Sep 21, 2015 | , | 0 Comments

Back in March, I challenged the members of my local gardening club to a chilli challenge.

All were given a packet of Chilli ‘Numex Twilight’, my favourite chilli for windowsill growing – it’s a manageable size for indoor growing, and at its peak you end up with a rainbow of decorative chillies that will get the admiration of anyone visiting the house.

chilliI set two classes for the challenge – most number of chillies on one plant, and the healthiest looking chilli plant. To level the playing field I provided everyone with a stash of 2 litre pots and the plants had to be grown in these. Other than this they had free reign on compost choice, fertiliser and training (staking, pinching out, etc).

Last Saturday I joined everyone at the local village hall for the end of season flower and produce show. I had been looking forward to seeing how everyone got on, but on Friday evening it suddenly hit me that I’d potentially given myself a really big task. “Why on earth did I choose most number of chillies as a category!?” I had visions of me being there all day, constantly losing count and starting again.

So as I sheepishly entered the hall I was relieved to see ten plants for judging with varied crops of chillies on them.

All the plants had chillies that I would easily recognise as Numex Twilight, but it was interesting to see the variation in habit and size. One reached well over 3½ foot while another wasn’t much more than 18inches high. Most had the small leaves expected of the variety while one or two had large leaves rivalling sweet pepper plants.

Lowest chilli count was 1 (an easy job for me!). Yet I awarded this plant third place in the healthiest plant category – lush foliage with plenty of life left in it for cropping through winter.

The heaviest cropping plant had 203 fruits on it, although none of them had yet ripened. The plant looked so healthy too, that I also gave it 1st place in the second category.

chilliJudging was carried out in the morning, I then returned for the open show in the afternoon, bringing with me my best Numex Twilight plant to show the rainbow of colours that everyone could expect from their plants. Winners announced, I was called on to read out the raffle winners, many of whom went home with Thompson & Morgan seeds for sowing next season. Winners of the chilli categories received seeds of my 10 favourite Thompson & Morgan chillies plus a book on chillies kindly donated by another member.

I received many a compliment for my chilli plant (admittedly grown in larger pot, but fed just once back in June).Returning home I decided to make a feature of it in the kitchen. Setting it alongside my chilli chain – a mix of chillies picked from my plants, all strung together with a needle and thread (the needle goes through the stalks so the fruit is undamaged). These are then hung to dry out ready for a long life of varied uses in the kitchen.

I hope you are all doing as well with your plants. I’d love to see how you are getting on, post your photos on the Thompson & Morgan Facebook page.
