Q.How To Cut A 9′ High Rose Bush Down To 3-4 Foot?
Had tenants in the house 2 years during covid, Rose bushes were un-tended but still doing great …. but too huge now. How far can I cut them down, and how? Should I fertilize after I cut? They have great gorgeous flowers & scent, but now being eaten by tiny green “slugs” on underside… should I spray w/ horticultural oil after cutting? Thank you.

Rose bushes can take a severe pruning in stride. If your bushes go dormant in the fall, wait till then to prune. Many people prefer to cut roses back in spring. You can spray Neem oil on the pests now. Here is more:
