delphiniums germinating now. What next ?

gloriag Floyd, VA(Zone 6b) May 26, 2005

I have been trying to grow delpheniums for years in 7a and never got the knack. Should I keep them under the lights all summer (and maybe put them outside at night for the cooler temps,) or should I plant them outside as soon as they get big enough, keeping in mind that part of June, most of July and August, have very high average temperatures? I do have a light setup in the basement where they would be cooler, around 74-76 during the day. I don't mind growing them as biennials or annuals if I can just get some of those gorgeous blooms!

Perhaps your answer may be found there?

If you keep them in the shade, there should be no problem at those temperatures. In fact. they should grow a lot better than in this climate where we are lucky to get such temperatures for more than a couple of weeks a year... :o(
