3. Growing from tubers


via houseandgarden.co.uk

Dahlia tubers should be planted directly in the ground from the middle of April. This means you do not need to wait till the frosts are over as the soil will insulate them. Make sure you make a hole that is 10-15cm deep and wide enough to fit the tuber comfortably. The eye of the tuber should be facing upwards. When planted, water thoroughly.
