How do you grow Dahlias?
I've been perusing some spring catalogues, and the dahlias look stunning.
I've never grown them ( except a small one that had floppy blooms) and I would like to know if they really do grow 8-10" blooms, and if so, how on earth do you keep them from breaking in the slightest breeze? Do they grow similar to peonies? Are they easy to grow? Bloom the first year?
