when to remove winter protection?
Any tips on a good time to remove winter protection in the spring? I have some small evergreen zone 5 or 6 rhododendrons that get some exposure to sun and wind.During each winter I have been using some evergreen boughs to protect their roots and burlap screens to protect from sun and wind. I am always eager to remove this stuff in the spring and wondering what is a good sign that it is safe to remove these? These are pretty hearty varieties but our climate/ location is not the best. Right now the normal minimum temp is -5 celsius (23F).
