I have six blue cypress trees planted around my new house along a wall. They were planted between rose bushes that have grown out of control around the cypress trees. When we cut back the rose bushes (vines), the cypress were very weak. Some are not able to stand straight on their own. How do we go about rejuvenating our cypress trees? They are 8-10 feet tall and their trunks are fairly thin.

The plant can reach a diameter of 20 feet. If the trunks are weak, I suggest a metal T-stake driven in the ground about 8-10 inches from the base of the trunk. Attach the plant to the stake with a non-binding material loosely in 2-3 places. Do not tie too tightly, the plant needs room for growth along with the ability to move slightly in wind andd breezes.
