It is safe to triim the rose bush now, in the spring. Cut the long straight stems 4 in from base. and do the same with those that are rangy. Cut the stems on a 45 degree angle. After cutting the rose water her generously. Roses may be trimmed in the fall as well. 20/20/20 plant food is a good source of nurishment. Ask a local greenhouse dealer for best furtilizers. Place straw, loam or compost around base of rose in fall for protection; removing in the spring. Then place that in your compost.In the fall my parents planeted a rose bush and they want to know when to trim it?
I've always trimmed mine in the fall after the first big frost. But you can do them in early spring before the buds start to form.
tell your dad that it is perfectly safe to prune the rose bush now and not to worry about how exactly he should do it a very famous English rose grower when asked how to trim roses replied '; get your worst enemy to do it';meaning that you could not cut them back to harshly
I believe when you prune off the terminal buds it signals the plant to get growing. Wait until you are passed you average last frost date.
