Answer 1

Here are some simple instructions on how to prune roses.

General Pruning: You do this to remove any dead or dying canes or spent flowers. It is true that you need to pick a set of five leaves, but not necessarily the first set. Pick a set of five that are pointing outward because that will be the direction of a new cane and flowers. If you choose one pointing inward then your canes can cross and will cause other problems. Cut the cane at an angle like this (/) about 1/4" above the five leaf set. It is okay to do this with each cane and especially if the cane is dying. It is also okay to do this throughout the growing season because it promotes new growth. Also, it is important to seal any pruned cane the size of a pencil or larger with white glue to protect the wound and promote faster healing.

Autumn Pruning: Any time between the first freeze of Autumn and the last freeze of winter you can seriously prune your rose down to about 2 feet. This will create a fuller, lusher plant for the new season. Once again you will want to cut at an angle. However, instead of cutting above a five leaf set, this time you will want to cut right above a node which will resemble a small, reddish, slightly pointed bump on the cane. Like the five leaf set, make sure the node is pointing outward.
