Re dahlia bulbs - I planted dahlia bulbs from Lidl last spring. They took a very long time to flower and some of them never flowered at all.
Now those pots have been outside all winter and there's no sign of life. I think the long wet winter has killed them.
Should I dig some of them up to check, or leave them for another while? Dahlia and tulip bulbs that I planted in the autumn are growing strongly, so I think the ones from last spring are gone for a burton.
Dahlia tubers are the opposite to tulips, you dig then up in the autumn (or protect them), store them in a frost free pace and plant in the spring.
We went to an NT garden yesterday the dahlias were protected with little straw cloches, with warmer winters thats enough in the south.
