Minimum Hosta Temperature:
I'm a new member and I live in Texas, zone 8a. I'm in the middle of doing research regarding the feasibility of growing hosta in my area? Some have told me that hosta need to have a winter of temps. around 40 F. for 4-8 weeks? If this is the case, what are the reasons? Will they not come back, or will they just not come back strong with new growth? Physically, how does the winter low temps. effect the hosta plant? I have grown orchids for years and I know that a couple of weeks at around 55 F. will induce spikes because it stresses the plant and makes it return to work so to speak. What effect does the cold weather have on hosta?
