MJ is like most plants, it can live down to a frost/freeze. It stops growing at 46f. Covered it can live through a frost. That is what we will do if we have a frost warning. We will stake the plants and cover with plastic bags. Our average last frost here is May 31. I haven't seen a frost that late one year out of five, but, it can happen.
Thanks for the mojo Rose. Things are looking different outside here. Some heavy brushing going on this year. The chipper is running through sharp blades every couple days. Manzanita city around here. We are gonna be surrounded by "defensible" space soon. We have it mostly but it will be cleared out by the end of next spring hopefully.
