tuberous begonias not dormant!
I've got two tuberous begonias (illumination series) under lights in my basement. They are looking pretty ratty (mildewy, etc.), but they just aren't going dormant! I've quit watering them and they seem pretty dry. A third one lost its foliage about 2 weeks ago (and had a decent sized tuber). They were all from seed last summer.
I was hoping to start the tubers up again in about a month or so--but these guys aren't dormant! Should I put them in an even cooler place without any light? I could just cut off the foliage, but it seems that letting them wither might transfer more energy to the tuber.
Will one month of dormancy be enough?
