Hi - I have had great luck with starting tubers indoors, despite not exactly optimal light conditions. I even had a bunch sitting under a coffee table receving indirect light (glass top)! When they all finally went outside after risk of frost had passed, they took off nicely, and bloomed like crazy toward mid/end July right until frost. Starting them indoors really gives them a head start - I just wish I had more space - I fear that pretty soon, the dining room and living room will once again look like a crazy woman lives there!

I hope that helps,

Anna

I had great luck with mine last year. The only window I had that wasn't shaded by a tree was east: not optimum either. I started mine on Easter weekend: did the same this year. I set up a card table in front of this window and put the pots on it. Rotated the ones that were closest to the window with the ones in the back every few days.

Then when it was warmer (mid-May?) brought them outside on the deck for more pot growth until regular planting out time in late May. If it looked it was going to be too cold overnight, I pulled them into the house: that happened only twice. The increased light made them bush out quickly. Most had about 6-8 true leaves when they went into the garden. They didn't have that much time to get leggy.
