Dahlia Plans for 2025

Twixmas is when my planning for next year goes into overdrive. One of the biggest tasks is getting my dahlia order in on New Year’s Day, yes and I do mean at midnight, before all the most sought after varieties are sold out!

Hopefully it means I will be near the front of the queue so that they arrive in late winter and I can pot up the tubers in our heated greenhouse and take some basal cuttings. I need to bulk up my numbers for 2025, as in the autumn I had to clear my old patch which had outlived its three year productive lifespan. A few special tubers were kept for propagation but the rest were retired to the compost heap, or bonfire if they showed signs of virus.

I am planning on supplying florists in 2025, so as well as a patch for our shop, weddings and PYO I will need a separate one for wholesale – mostly this will be for event florists’ wedding work. If you are a local florist and would like to find out more please do get in touch and I will send you our brochure.

With about five different suppliers and hundreds of varieties on the long list I begin the process of narrowing it down to 60 varieties. I know I need at least 12 tubers or cuttings of any variety to have enough to pick each week for my retail customers. For my wholesale customers I am looking for less range but larger numbers of a few favourites. Being a visual person it helps to bring out the sticky notes and graph paper. I like to colour code my rows as it is helpful with planning and also with picking when they are all in flower. Another consideration is including a variety of forms and a similarity in stem length – nothing too short as it can be tricky with the support netting.

Each bed on our farm has been measured and coded so I can calculate and record how many dahlia plants it will take to fill. I know from experience that it’s a fine line from not enough to way too many, which leads to a waste of time and profit deadheading them all.

There are always the old favourites that have to be included but the top ten I have listed below are based on their cut flower credentials and availability. I know it can be annoying when you love a recommendation and then find it’s not available, here’s looking at you ‘Carolina Wagemans‘….

  1. Wine Eyed Jill‘ – versatile, very early with quality blooms throughout the flowering season, productive and with long, clear stems for easy picking. Here she is (top right) with more must-haves – ‘Sweet Nathalie’, ‘Rosemary’s Blush’ and ‘Break Out’.

2. ‘Purple Flame‘ – gorgeous rich colour with just the right amount of warmth to tone well with other colours, lovely informal anemone-type flowers.

3. ‘Porcelain‘ – my most romantic dahlia, a delicate pinkish mauve waterlily-type, tall with long stems so useful for large arrangements.

4. ‘Peaches‘ – it’s good to see this one available again, it has such a unique shape and I love the deep orange and creamy peach colouring. Image photographed by Clive Nichols.

5. ‘Senior’s Hope‘ – goes with everything and will always add a touch of class. It is a bit short so is a good contender for a large pot or trough.

6. ‘Copper Boy‘ – even though I find ball shapes too formal I can’t resist this uniquely coloured dahlia, looks great with Rosa ‘Hot Chocolate’.

7. ‘Nulands Josephine‘ – my favourite pompom, a similar to Burlesca but with more rhubarb than custard in its colouring. Pictured with another favourite Cornel Bronze.

8. ‘Josudi Andromeda‘ – David Hall has bred some fabulous small cactus-types all with the prefix Josudi, this one is a soft, blush pink. Tall, clear stems. It is pictured in the bowl arrangement below.

9. ‘Preference‘ – a semi-cactus, dark clear stems and the softest most perfect peach. Also one of our most productive dahlias.

10. ‘Penhill Dark Monarch‘ – I love a dinner plate dahlia especially when they are quite scruffy. Image photographed by Clive Nichols.

If you don’t have room for 60 varieties and are looking for some inspiration. you can always come and see our patch and even better pick and arrange with them during a workshop. I will be holding our popular dahlia class on Sunday 7th September as part of my Garden to Vase series. We will look in depth at all aspects of growing dahlias for cutting including variety selection, propagation, overwintering and how to achieve continuity of quality flowers. The day includes picking your favourites to arrange and take home in one of my hand-thrown bowls.

Happy New Year and dahlia shopping!

 

 

Dahlia Grow Along Part 3

Hello and welcome…

I have a feeling this might have been due a couple of weeks ago but the season has moved from pottering and contemplating to racing around the garden at full throttle. With a fully booked season ahead I have a lot of sowing and planting to do. Fortunately my team is back with some new additions too so we are certainly getting things done at present. After a few months off, my floristry skills have been cranked into motion again with eight weddings so far and plenty more in the coming months. I have done more talking in the past few weeks than I did all winter with our courses and gardening club talks.

Anyway, back to the DAHLIAS…, I took the first basal cuttings off my tubers this week. So here is how to turn that one favourite, special dahlia into an entire row of them.

I took my tubers out of storage back in February and potted them up so the crown was sitting above the compost level.

They are then placed in a warm, bright position to bring them into growth early. I want cuttings as soon as possible and so I use a heat mat or a heated sand bed. A greenhouse is ideal where the bright light conditions will produce stocky little shoots. This usually takes a good three weeks.

Now arm yourself with a sharp, clean knife, a plastic bag and some rooting hormone.

Cut the shoot right at the base, as close to the tuber as possible (preferably with a sliver of the tuber), being careful not to damage surrounding shoots.

Check that your cutting has a solid centre, if hollow like a straw discard it as it will never root properly, only rot.

Remove any lower leaves and dip the end in the rooting powder. If there is still a lot of leaf cut the remaining ones in half.

I like to take a lot of cuttings so mine go into plug trays but around the edge of a pot works just as well.

Label and date your cuttings for reference later.

The cuttings must be kept out of direct light in a warm, moist environment until they have rooted which will take about 2-3 weeks. A clear plastic bag over your pot of cuttings will keep them from transpiring and expiring. Be patient and no fiddling…!

The next Dahlia Grow Along post will be about growing them on and planting them out. I am going to get a head start with some of the giant varieties in the polytunnel.

 

 

Dahlia Grow Along 2015

This time last year I introduced my first Grow Along with a real garden favourite  –  Sweet Peas.

Now is the perfect time to start a new one with the first flower I ever grew for cutting twenty years ago – the Dahlia.

Green and Gorgeous, an ethical flower company which grows, arranges and sells locally grown flowers.

Although dahlias were deeply unfashionable at the time I was working for a die-hard Dahlia lover called Maurice Fitzmaurice. A wonderful big bear of a man with a penchant for giant Dahlias. His passion (actually obsession) for them was kind of infectious and as his gardener I spent hours attending to their every need and learning the most labour-intensive ways to grow them, as he was a stickler for detail.

My treat was to pick a big bunch to take home where I would while away hours (as you can in your 20s) contemplating their almost impossible forms and colours. Sometimes I would wear them in my hair, which I think was pretty impressive considering their size.

Maurice’s favourite was ‘Hamari Girl’ (big, pink and blowsy – see above) and when he died I went and dug up the tuber from his garden (but don’t tell the new owners…). I propagated and grew this variety in my first year here at G&G.

Since then I have mainly downsized to small and medium types but expanded my repertoire to about 80 varieties which are constantly chopping and changing. I have also simplified my cultivation methods to save time but still get amazing results for cutting.

Today I am going in to my dahlia store to select some favourites to be propagated for the season of 2015. I haven’t got room to take cuttings of them all so how do you choose a good variety for cutting?

Colour – a personal preference I know but as weddings are our main business my selection tends to follow trends.

Habit – a close up picture of a flower in a catalogue might be enough to persuade you to buy, but it doesn’t tell you about it’s growth habit and whether it produces good stem length.

Vase life – size and shape are the secret here, the majority of mine are small and miniature varieties in either decorative, ball or waterlily.

Productivity – another attribute which is difficult to predict until you are actually growing them, dahlias vary enormously in how prolifically they flower.

Longevity – some tubers store more reliably than others, possibly because they put on good strong tuber growth so do not shrivel up or rot over winter.

If you do like to try before you buy I recommend visiting the Wisley trial grounds and a couple of Dahlia nurseries with show beds in August/September.

So what is my short list for propagation? – not all of these, way too long for my heat bench!

My top ten is always changing but last year it was Cafe au Lait, Eternal Snow, Eveline, Acalpulco, Carolina Wagemans, Tiptoe, Porcelain, New Baby, Little Robert and Maldiva.

In next week’s post I will talk about varieties in more detail and where to source them if you are starting from scratch. I will also take you through a pictorial guide on how to propagate from tubers in case you have some favourites in storage.
