I've found growing dahlias far easier to grow from seed rather than tubers.
The seed grown one's have produced cracking tubers after flowering, which stored well over winter but most have never grown again in spring. This year I bought two new tubers...and...only one sprouted.
The tubers which sprouted are in pots and romping away, seeded ones still fairly small, but outside in pots and I'm confident they'll produce some cracking flowers.
Excellent trial Ww. Pots in GH, seems like a good plan for my seed grown dahlias, or putting in a sheltered spot at the end of this year.
