I don't think so. Philadelphia is more mild than southern New York and I usually wait til the second week of May. Good luck.

tessa74 I planted my tubers in early April last year and had no problem. We have been plagued with a lot of rain here on the west coast and chilly temperatures this year. It is hard to work in the garden when everything is waterlogged. I didn't plant any tubers that did not have an eye this time because it is so annoying to wait for a tuber to grow only to be disappointed. I actually began planting on April 10th. I laid my tubers out into trays on my porch and sprayed them with water every 2nd day to keep them from drying out and checked for eyes then too. As they showed themselves they got planted.

The Dahlia farm gave out new instructions for planting this year. So this year I dug the hole 5" down and placed the tuber in a vertical position. Placed dirt all around the bulb, but left the sprout exposed and uncovered. As the sprout grows, place dirt around it until it is even with the ground around it. This is so much better because you can see the sprout growing instead of wondering if it is growing. I always put an inch of dirt over the tubers before. How do you do it?

My dahlias are now planted. Just came home from wintering in Florida. Checked my tubers and they wintered just fine. Most eyed up nicely. Bought 14 new varities for this season. I have way more than I need and will probably give many away and make someone else a Dahlia lover.. So excited for this season...
