Re: Dahlias
I have been growing them for over 20 years, I have found that they do like a lot of sun but I do have two varieties in semi shade and the do well.
Hard to grow...no...they are a tuber and shallow planting in the ground or pots well after the chance of frosts is over, for me in the Midlands that’s late May/June, they are very greedy so need regular feeding and watering.
When I first started growing them in the ground I would religiously lift them after the first frost and store them, now I leave them in the ground because tge winters are warmer.
The pots I do put under cover each year because I don’t want tge tubers to get water logged.
There is a lot of info online which will explain it better than me, but try one variety in a pot and see how it goes?
