I'll be able to answer your question in a few years, after I get the kinks worked out or give up.

Thanks for the info!
I’ve got good black soil that produces a great garden. Petunias? I am good with them until it gets too hot...but that may be partially my fault since I don’t pinch their little heads off.
Probably to late in the year to start this experiment...but I may give a couple of plants a try next spring.
