Proper Way to Trim a Rose Bush.
Pruning is an important part of caring for rose bushes, as proper pruning improves plant health and helps maintain size and shape of the bush. It also helps.

If it is in the back of a border, leave it a little higher; for the front of a border, trim lower. For hybrid teas in particular, the lower you prune, the bigger the flower and longer the stem - good for cutting and exhibiting.
