Basement too cold?
I am trying to keep some cuttings from annuals in my basement over the winter (I'm pretty new at this). I have some coleus and impatiens under florescent gro-lights and they did very well for the first couple of months. Now the coleus is getting black stem rot and the impatiens are losing leaves.
I'm worried that my basement is too cold since I live in an old house. I've read in other postings about fans, heaters and heat mats and don't know which options will help me.
I've managed to take cuttings from the coleus and they're in a glass of water on my kitchen windowsill for now, but I don't have enough light in my windows to keep all the cuttings.
