Q: When is the correct time to prune roses in the Tucson area? And do you prune them like we do in the Midwest, i.e. cut back near the ground?
Answer: The pruning of roses is recommended twice per year in Tucson. The first pruning can be done in late January to a height of 15 inches or so. This time remove all dead wood, crossing branches, and small leaves. Seal the fresh pruning cuts with Elmer’s glue to prevent insects from invading the newly cut branches, fertilize, and then water.
In mid-September a lighter pruning is recommended. This time remove one third of the plant along with any diseased or dead wood but leave any leaflets. Seal fresh cuts with Elmer’s Glue, fertilize, and water.
The Pima County Master Gardeners teach classes on roses and other things at some of the public libraries in case you’re interested. Check your library schedules or call the Extension Office for more information,626-5161.
