American bittersweet

Question

I have a small seedling growing inside the house. When should I plant outside? Does it have to be hardened off before planting? I live in Zone 7 in East Tennessee.

Answer 1

It is best to transplant your seedling around the time of the last frost date in your area, which should be around mid-April for you. Yes, you should harden it off as described here:
