Over Wintered Dahlias
I overwintered 27 Dahlias grown in individual 10" pots under my carport. In March I uprooted one Dahlia & sought professional advice from my local garden centre. On inspection the plant was found to be healthy & I was advised to feed & water. I have done this 6 weeks ago & up to now the plants are showing no signs of life. They are now outside in front garden. I cover them at any sign of frost.
When will these plants show any sign of regrowth?

Hi Billy, I'm in the West Mids and have 4 Dahlias in pots that were planted in the autumn. The last one has shown signs of life this week. So I shouldn't lose hope yet.
I planted mine out last week, total mistake as all the growth got nipped by the frost (they're now under cloches - especially as a frost is predicted tonight)
silly question, were you keeping them somewhere warm and light to get them going in the spring??
Had mine in the greenhouse (with a heater set to frost protection only). Have had them outside for a week or so now, still in pots. We had a slight frost but nothing drastic and they seem OK.
I didn't even lift my Dahlias, I didn't have room to store them over winter so I left them in the ground after I had cut them off and just covered them with fleece. I had a look at them yesterday and they are all showing signs of growth. I am in the south though, in Dorset.
I'm in East Cheshire and the ones overwintered in my greenhouse (just frost free) are only now showing the very first signs of growth. The ones stored dry and potted up indoors are raring to go and some even have flower buds. They come from Mexico - they need warmth.
I've been wondering too Billy, but as I'm in Scotland I feel there is still hope. The Dahlias I've grown from seed are coming on quite well in the cold frame but we are predicted -3c tonight. Searching for bubble wrap as we speak
I don't lift my Dahlias either Donut, these were new ones that I potted up. Mine are planted on a dry and sunny part of the garden and so far I've not lost any. Some of them have been in around 5 years and have survived quite cold winters during that time.
So if the Dahlias are left out in pots over winter with fleece over them, at what point do you start to water them and take the fleece off - when they start growing and/or the frost has gone away? This method sounds to be a much better than the one I have been using. I think I've managed to kill mine from last year!
