I'm a newbie dahlia urban gardener. I've always loved this flower, but it's my first attempt planting them. I know it will be a challenge -- all I have is a smallish deck in New York City, and it doesn't get a lot of sun. I planted 4 tubers yesterday, each in a different pot. Today we're getting quite a bit of rain. I've read that tubers do best when the soil is dry, and that they're supposed to be watered only after sprouting a few leaves. Unfortunately my deck does not have any shelter, and I'm afraid the tubers might rot. (It's supposed to be partly cloudy in the next few days, with chances of scattered showers.) Would it be advisable to dig up the tubers and try to dry them with paper towels? Or should I leave them alone and hope for the best? Help, please!
