“When I am an outdated girl, I shall dress in purple” (Jenny Joseph)
Ever more I’m obtaining to kick-start myself in March – I blame it on the January and February temperature, but I imagine there’s an aspect of growing old disgracefully there.
And I’m not the only matter needing kick-started this month. My dahlias need to have it much too. Commonly I carry them up from the cave the place they’ve over-wintered and toss them into the ground at the stop of April, presenting a little bit of safety if late frost threatens the young shoots in May perhaps.
But, possessing been an anti-dahlia snob for a long time, I’m now a transform and keen to treasure, alternatively than demonstrate contempt. Is this an additional scenario of ageing gracelessly: have I out of the blue become Jenny Joseph’s outdated woman, full with eye-splittingly purple, ghastly, dahlias? (I previously had the purple hat…).
No matter what… this yr I’ll be accomplishing the proper factor and potting up my dahlias in early March and increasing them on in the unheated greenhouse, all set to plant out right after the saints de glace (Ice Saints) in May possibly.
I’ll pot them into compost in shallow trays with the tubers rising out of, but nonetheless able to root into, the compost under: they will not be buried completely. This saves on the price tag of compost and helps when I occur to take cuttings – although I’ll have to continue to keep moisture stages up so that they really don’t dry out.
Mainly because, you see, it is the cuttings that are really at the coronary heart of all this supplemental exercise. I enjoy dahlias so a great deal now that I want much more – and I have heard from qualified growers that dahlias developed from your own cuttings really produce far better top quality bouquets (never check with – I have no concept why!).

I will leave about four or five shoots per tuber and, when the shoots are about 8 to 10cm very long, I will minimize any shoots more than that variety away, with a minor sliver of old tuber at the foundation to supply defense towards rot. Just after getting rid of the base leaves on the cuttings, they’ll go close to the edge of a pot filled with quite properly-drained compost (likely about 1:1 compost to vermiculite).
I may put the pots beneath a plastic propagating case, but I also like to use the pots in which factors like trailing petunias have been obtained – the form with the plastic body above the leading – as mini-propagators. Pop a plastic bag on best of the body and you’re absent …
Dahlias are really photosensitive, so working day size is important for rooting cuttings. When mild degrees are lessen than 14 hrs a day, the cuttings will are inclined just to make callus at the foundation, relatively than feeder roots – but if you’ve potted up your ‘mother’ tubers in March, the ensuing shoots should really be ready for cuttings in the 2nd 50 percent of April when light-weight concentrations are climbing and roots need to variety in 10 to 14 times.
For the initially calendar year, the cuttings are greatest planted out in a nursery mattress exactly where you can retain an eye on them – later on in the summer time, when the gentle concentrations are much less than 12 hours, they will start out to build their very own tubers and, later, you can carry the modest tubers for the winter season.

So what cultivars am I desperate to make much more of? In spite of having a 30-yr-in addition hatred for these flowers, it is now the supper-plate-sized, a lot of petalled blooms of creamy-pink ‘Café au Lait’ (pictured, top) that most give me the shivers. No question it’s the florists’ global favourite – for weddings, one particular presumes. But how on earth do they quit these substantial nodding heads hanging down, as they usually do when I just pop them in a vase on the kitchen table? I’d guess there have to be a bit of wire concerned.
Soon after that, I’d say you just cannot beat the ‘Bishop’ series as garden vegetation, and ‘Bishop of Llandaff’ (inset)with its beautiful dark foliage and solitary scarlet bouquets is a rather unique aged favourite, while I’d like to insert ‘Bishop of Auckland’ as effectively. Dark foliage is a serious reward among the backyard garden greens, even though possibly a lot less crucial in a vase, so the deep, inky-red bouquets and pretty much brown foliage of ‘Karma Choc’ are also treasured in my backyard.
In actuality, the whole Karma sequence is effectively worth trying out. I also expand ‘Karma Serena’ – a flawlessly formed white flower, with a greeny-lemon centre. ‘Karma Lagoon’ is extremely robust developing – whilst the brash purple normally takes me into outdated-lady purple territory! However, this is the dahlia – with ‘Karma Serena’ – that delivers me the most bouquets at the close of the period. In spite of that, I prefer the much more civilised, dusky tones of ‘Thomas Edison’ (not a Karma).
I’m a bit of a sucker for the purples and ‘almost blacks’, these kinds of as pompon ‘Arabian Nights’, cactus-flower ‘Nuit d’Eté’ and ‘Chat Noir’, as well as the expensive small pompoms of ‘La Recoleta’. But my most exciting additions for 2022 will be two orangey cultivars. ‘David Howard’ in burnt orange with purple-green foliage and ‘Nicholas’ in refined peach have me all revved up for their arrival in February.
They must glimpse great with my blacks and my sweet, lessen increasing, ‘Totally Tangerine’, with single anemone flowers.
