tree collards in hot-and-humid climates
I live near Tallahassee, Florida, USA. We have long, hot and humid summers, and a few hard freezes a year.
I recently purchased some tree collard cuttings, and am rooting them now. I'm wondering if anyone on this list has experience or knowledgable advice about how to help them thrive in (or even survive) our hot summers.
Also, will they handle freezes?
