Last date to plant hosta? Zone 5-6.
Does anyone have a guideline on the last safe date to plant hosta? I have several that still need to go in the ground and it's not an easy exercise because I have voles (so I need to get large pots, line the bottoms with landscape fabric, etc.), plus I really need to move a bunch of things in that garden around. We haven't had a frost yet. I'm in southern Maine, on the coast, so on the border of zone 5 and 6. Thanks.
