Chelsea Girl: my visit to The RHS Chelsea Flower Show 2013

It could only be Chelsea!

As my first year of garden design training draws to a close, I was determined to visit Chelsea Flower Show.  It was an extraordinary new experience - I'm as passionate about ornamental plants as the next person, even though I focus on growing edibles - and Chelsea is deservedly the flagship show of the RHS.

Comprehensive media coverage is fantastic for those that can't get to the show but the real thrill is to be there and experience the plants and gardens up close - and to have the time to linger and think, something a television show can't do.

The weather can make a huge difference to enjoyment of the show and I struck lucky with a dry day of mild temperatures. The designers must have been relieved as the gardens were shown to perfection and interviews in-situ were easier for not being rained on.  It would have been possible to dash into the Grand Marquee, should the need arise, but that area was humming with people who'd come to see the exuberant plant displays.

It was fun trying to match the designer to the show gardens; Christopher Bradley-Hole's style was very recognisable in his clever and subtle interpretation of the English countryside, as was Jinny Blom's innovative planting in the Sentebale Forget-Me-Not garden and Roger Platt's romantic cottage garden style. I wasn't expecting to see Homebase at the show (given their propensity for killing off plants in their garden centres) but Adam Frost had created a realistic and achievable edible garden for them; full of good ideas for incorporating edible plants into an ornamental garden, there was plenty to take away from here for the home gardener.  Chris Beardshaw's garden for Arthritis Research was beautifully layered in telling the journey of an arthritis sufferer and worthy of a longer look. It deservedly won the People's Choice award.

The garden that I would award 'Most thought-provoking' to would be Jo Thompson's Stop The Spread; with half the space allocated to an avenue of dead trees, it's been designed to highlight the spread of pests and diseases that are destroying plants and trees in the UK. The contrast between the two areas of the garden certainly provoked comment - and, hopefully, further thought.

'Stop The Spread' by Jo Thompson

Looking for somewhere to sit for lunch, I wandered on into the Artisan Gardens, tucked into the woodland area.  Each tiny garden told a story: a glimpse back into the magic of childhood for the NSPCC, a Hebridean weaver's cottage, the Yorkshire Tour de France, a physician's healing garden …

Clockwise from top left: Yorkshire garden, Hebridean weaver's garden, physic garden, NSPCC garden.

But out of all this extraordinarily beautiful and inspired planting, one garden that I had to see was 'Bird Columny', the Fresh Talent creation of three very talented students on my course at Capel Manor.  The 'Fresh' area is where cutting edge designers can be showcased.  The garden spaces are set around three laser cut columns and it was one of these that the Capel team were given to plant up.

Thankfully my allegiances weren't tested as 'Bird Columny' (their exhibit) was a brilliant naturalistic salute to UK hedgerow plants and their benefit to wildlife. At the end of Press Day judging, the RHS agreed and the team - JAM garden design - was awarded with a Fresh Talent Gold. I know that the team, and Capel Manor who trained them, were thrilled with this achievement.

As this was the first time of visiting the Chelsea Flower Show, I can't measure it against previous years, suffice to say that I found it enthralling. Talking afterwards to gardeners and media folk, I could tell that opinions were diverse. It was interesting to see how people's reactions to the show varied but I'm definitely good for a few more years of visiting this wonderful show.

… And I haven't even mentioned the retail therapy! 

How to cheat at growing herbs

I use a lot of herbs in salads and my cooking and, until the growing season gets going in late spring, I find myself paying for pots of supermarket herbs knowing there is every likelihood that they'll keel over before I've finished using them. This seems to be especially true of my favourite herb, coriander (which you may know as cilantro).

It's been the same story with parsley, thyme and chives - in fact every bought herb!  But no more.  I have a built in windowbox on my balcony, just 9 inches depth and width (front to back) with a length of 70 inches. At the beginning of winter, I transplanted some shop bought parsley into the windowbox thinking this might lengthen its useful life by a week or so.  It's still flourishing.  Several weeks ago, I did the same with a pot of coriander.  Same story.  In fact, both have grown and are looking very lush. 

So, whether you want to avoid the wait for home-sown herbs or simply to extend the life of your shop-bought herbs, here's how to do it.

As soon as you bring pots of supermarket herbs home, take off the cellophane wrapper, give them a good watering if the soil feels dry and prepare a hole in your planter, terracotta pot or window box.

If you're starting a planter from scratch, use multi-purpose compost - and, if you have any, add several handfuls of perlite or grit added for drainage.

The hole should be at least a third larger than the pot the herb came in.  A tiny sprinkling of bonemeal well mixed into the soil at the bottom of the hole will help the roots to establish in their new home. (Don't worry if you don't have any.)

Take the herb out of its pot, carefully tease out one or two roots if necessary, and place in the hole.  Put the soil back all around the plant, gently firming it in and making sure that the plant is sitting at the same soil level as it was in its pot.  Gently water the soil all around the plant to settle the soil around the roots - and don't forget to keep the soil moist (but not wet) by checking daily to see if more water is needed. (Do this by pushing a finger about 2 cm into the soil; if the soil feels dry, the plant will need watering.)

There.  That should take all of 10 minutes, or less, and give you weeks of lovely fresh herbs*.

Herbs produced for supermarkets are intensively grown with too many plants in the pot to survive beyond the seedling stage.  There simply isn't enough space or nutrients in the pot for the herb to grow well.  By transplanting into a bigger space, the roots can seek out more nutrients and the plant not only survives but thrives! 

*Coriander, parsley and chives respond well to having the occasional stem snipped off and will reshoot (but not forever), especially if the soil around them is kept moist (but not soaking!).  Coriander doesn't normally reshoot, so I imagine that this is because, as the plant is trimmed, smaller seedlings have access to light and air and so grow. Whatever the reason, it works - and it's so great to have fresh herbs on hand!

Typical British spring weather!

Two days ago, on popping down to the gardens, I was astonished by the sight of the blossom on the fruit trees.  The warm sunshine had brought on a display that would have done a bridal florist proud.  Waves of foaming white blossom graced both cherry trees; the apple blossom, although less prolific, was equally beautiful.

Yesterday, as with the rest of the UK, we were hit by gale force winds.  These have eased very slightly for today but I'm anticipating that there won't be much blossom left by the end of the weekend so I'm pleased that I took these photos for posterity.  Only time will tell if the flowers were pollinated in time to produce fruit this summer.  The pears and plums had already lost their blossom so I remain slightly hopeful of some of the trees producing.

For the past few years we've had a blast of warm weather followed by April showers and May gales.  I remember planting out my beans and sweet corn a couple of years ago after weeks of warm sunshine. The next day they were decimated by gale force winds and lashing rain and I had to resow.  This year, I'm being more cautious - I still have lots of seedlings on my balcony. They must go into the garden soon so, once the winds have died down, a nice bout of British late spring weather will do me nicely - and by that I mean cooler temperatures - around 12C (54F) - and plenty of showers.  I've appreciated the warm sunshine while it lasted but now it would be nice to return to a gentle move towards summer.  Well, a gardener can dream ... this is British weather, after all. (And Chelsea flower show starts in 10 days which is pretty well guaranteed to mix the weather up!)

How to grow Honeywort - one of the best bee-friendly self-seeders for your garden

In my last post, the photo of Honeywort (botanical name Cerinthe major 'Purpurescens') flowering ridiculously early certainly generated a lot of comments. It turns out that this plant is a favourite with many folks and deservedly so.

A comment left on that last post asked for advice on growing Cerinthe from seed saved last year.  I have to say that it couldn't be easier.

At this time of year (late spring), you can sow them outside, direct into finely raked soil. Water the soil first and cover the seeds with a bare quarter inch of soil.   You can also do this in autumn (late September) to get them off to an early spring start.

On the other hand, if you only have a few precious seeds, start them in small pots or modules indoors: soak seeds overnight to break down outer casing, sow at same depth of seed (about 2 - 3 mm deep) into free draining soil, wait 7 - 14 days for germination, let the seedling grow a bit before potting on; at about 3 inches tall, with 3 to 4 leaves, harden off and plant outside, leaving about 40cm between plants.

They're a Mediterranean plant and their waxy blue-green leaves are a big clue as to where to site them - a nice warm spot with plenty of sunshine will suit them best and see them thrive.  The soil doesn't have to be anything special, but must be well drained.  Mine grow on top soil over London clay and usually reach about 50cm high.

The stems can get a bit straggly in time and, as the drooping flowers are the whole point, it's quite nice to just support the stems a bit by staking, if you can be bothered. If you plant them closer together, they'll  prop each other up but won't look as nice.

They flower over a long period.  If you're lucky, as they develop you'll get blue-green leaves with deep blue bracts surrounding a purple flower.  This isn't always the case though;  I've had Cerinthe with grey-green leaves and pink flowers in previous seasons.

Remember these plants are really good self-seeders; seedlings will pop up every year once you've had one plant in your garden.  Every purple flower has two fat seeds inside; not all will germinate but it's a good precaution to collect the seed before it drops.

Like Marigolds, etc, Cerinthe seeds can also be sown in the Autumn for earlier spring flowering. They are hardy plants and, once established, will pretty much cope with anything.  Slugs don't like them.  This is the first time that mine have come through the winter.  The warm extended autumn of 2011 meant that I pulled the ropey looking plants much later than usual, giving the seeds time to drop.  The cold and rain of 2012 meant that the conditions weren't right for germination until late summer so my plants were still relatively young by the time winter arrived and were left in situ.

A few gangly sorry looking specimens were put out of their misery earlier this year but the healthier ones were left - and I have early spring flowers as a result. It's lovely to see as other self seeded flowers (nasturtiums, sunflowers, marigolds, orach) are only just beginning to get going.

They're not edible but are a real magnet for bees as the purple flowers are a good source of nectar. They also make an interesting cut flower and will last better if you sear the ends of the stems in hot water for 30 seconds.  Grow them with Escholzia (Californian Poppies), Atriplex rubra (Orach), Verbena bonariensis, Bupleurum rotundiflorum and Linaria (toadflax) for a colourful display.

I hope this post has been useful and will inspire more people to grow these lovely plants.  Seeds are available all over the internet, although they're unlikely (but not impossible) to be found in garden centre or supermarket seed racks.  I started my Cerinthe stock with one small plant bought from Sarah Raven's nursery at Perch Hill and saved the seed each year thereafter.

It's all bloomin' lovely!

I've spent the weekend sowing seeds and heaving out weeds.  I was in the garden by 8 a.m. on Sunday morning, appreciating the stillness and warm sun on my back.  It felt really good to be outside without a  woolly hat and warm coat, reconnecting with the garden and taking the time to really take stock of what was going on.

After the big Weed Out: 16.5 square metres of weed free tidiness, ready for planting.

Mostly it was a case of clearing the weeds (Hairy Bittercress and Chickweed) from the fruit tree border - a job that brought me up close to the blossom on the trees as I have to clamber into the walled border.  There's no rain or frost forecast for at least the next 10 days and the warm weather has certainly got the bees buzzing around.  I am therefore quietly optimistic of having some fruit this year.

One of the cherry trees - a Morello - was relocated to a walled corner last year (just seen in the distance, by the steps); its blossoms are already open.

The other Morello has hundreds of buds just waiting to unfurl...

The apple trees, both Braeburn, didn't produce one solitary fruit last year.  This year I've counted 12 clusters of blossom on one tree alone.  I'll keep an eye on these; if they all pollinate, I'll need to thin some of the fruit later on.  It's the same story with the pears and plums which is just wonderful.

Throughout the garden I'm finding self-seeded Orach (Atriplex rubra) also known as Mountain Spinach.

It's both an edible and ornamental, with edible young leaves - salads or cooked like spinach - and the most glorious bright pink seed pods later in the year.  I bought one tiny plant at an NGS plant sale a couple of years ago. Last year a transplanted self-seeder grew to over 8 feet tall; the dried seed pods looked so wonderful that I left them in situ and the wind has done the rest.  The seedlings can easily be pulled out if unwanted or transplant really well. I shall, of course, keep several for my Salad Challenge.

Can I just indulge and show off these two beauties?  The Cerinthe (aka Honeywort) seed blew into a pot of Lemon Balm last year, grew to a foot high, just about survived the winter and has revived itself to flower early.  One of my absolute favourite flowers, I love the glaucous leaves and purple flowers and grow them to provide food for the bees so that they'll home in and find my beans in the process.

And, lastly, an Aquilegia I bought recently - another Morrison's bargain - that has established really well into my new shady border.  I can't get over how pretty it is and stop to look every time I pass by - which is kind of the point in planting up a border previously used as a cat toilet/rubbish dump.

Btw, that was definitely not a 15 minute blog post! Too many photos. Just came in under one hour. Ah well.
