There are three possibilities for lack of flowering among the hydrangea species. The first two – too much shade and improper pruning – apply to all hydrangeas, while the other – weather-related damage to flower buds – applies primarily to the bigleaf hydrangea.

While most Hydrangea species benefit from some shade, too much shade can reduce flowering. This is particularly true of panicle hydrangea, which is the one Hydrangea species that grows well in full sun. If you have a hydrangea that used to bloom well but now flowers only sparsely, evaluate whether the growth of nearby trees has reduced the amount of light that reaches the hydrangea. If so, you may want to consider moving the hydrangea to a sunnier location.

There are many methods to provide winter protection for roses. The whole idea of winter protection is to keep the plant uniformly cold and frozen all winter and prevent the damaging effects of alternate freezing and thawing. Whatever method is chosen, don't begin covering plants too early. Wait until a hard killing frost has caused most of the leaves to fall. You may also want to wait until the temperature has dropped into the teens for several nights. Prior to covering, remove any foliage or other debris that might harbor disease for the next season.
