I am new to posting, but I have really enjoyed the helpful advice I have found in the past. Last April I planted two Forever Hydrangeas on the north side of my house in upper CT. They did beautifully throughout the spring, summer & fall. I did not protect them over the winter, but had planned on covering them with cloth in the evenings starting in April this year. The reason why is because last year, I had planted them during a warm spell, but, of course since this is New England, we had a couple nights of frost a few weeks later which killed the new growth on the top of one of the plants (it did recover nicely though). My question is: should I have been protecting them all winter OR is it ok to only protect the new growth in the spring from potentially frosty nights after growth has begun? I hope this isn't too wordy!!
