We have been on generator power since the storms of last Friday. Turns out that the exhaust was blowing right onto some of my hostas and I didn't realize until after two days. (Apparently we have never needed the generator during growing season in the past because these hosta have been in this location for 3-4 years.) So at 9:30 PM, in the near dark, I'm frantically digging and moving hosta to anywhere else I can find space. My question is: if all the foliage is burned to brown will the roots survive and give me a plant next year?
