I planted a whole load out last year, tubers straight into good soil and they all grew but were not bushy and tall as I had hoped. I didn't get round to digging them out in the autumn, but decided to let them take their chances. We are in the south and the border is sheltered. They have all come up again miraculously! I have fed them, (chicken manure pellets dug in and tomato feed) pinched them out, watered them well and they are still weedy looking. Some are flowering and others I appreciate may be later, in August.
What really brought it home to me was that we visited West Dean Gardens last summer, and their dahlia bed in the cutting garden was just stunning. How can I get my sad specimens to look like that? I've just read the article in this month's Gardener's World mag about dahlias and I don't think there's any mention of feeding!
