Oops, I was wrong -- the temps are going to dip into the upper 20s this week. My husband suggested sticking them, pot and all, in the compost/leaf pile to insulate them, but I'm worried that might get too warm and put them into shock when they leave the toasty composting warmth and go into the cold ground...help!

For brief freezes, like a dip into the upper 20's overnight, I think your plants should be fine. You might want to move them temporarily up against the wall of your house for additional protection, place them under a larger evergreen shrub, or onto a semi protected porch to ease any worries. Adequately watered, of course. In a pinch, you can group them together, cover them with an old sheet or tablecloth.

Protect them from direct sun, wind and deer. They will be OK. The sooner you plant them the better. Don't water too much. Keeping the soil too wet is one thing that will definitely kill them.

Wilt-Pruf is only necessary if you can't protect them from the wind and sun. Wilt-Pruf is more important after planting since if you plant properly by opening up the roots, you will disturb the roots and cause some water stress.

I've moved them into a sheltered nook of the house out of the sun, so here's hoping they make it.... I will certainly use the Wilt-Pruf when I get them planted. Thank you for your help!
