WS'ing Coleus and Celosia's for Zone 6 and under
I've read a post where one did not get much germination WS Coleus. I would like to hear from those in my zone or colder when to WS these. I have the seeds. I don't want to WS too early.
Also would like info. on Dahlia seeds. They don't like the cold. But can they be WSed?
