triming overgrown roses after they start budding
We have about six rose bushes in our yard. They didn't get pruned last year. Now they are a tangeled mess. I didn't get to prune yet because of freezing temps. Now they have been budding for about three weeks. They have lots of green foliage. The large stocks are taller than I would like. The small branches are everywhere. How far back can I cut them at this point?
When it comes to roses and pruning they can withstand being cut back severely. The only concern is areas with bark no longer have latent buds to grow back, so restrict your pruning accordingly. you will want 3 to 5 Cains about 18" tall when your done.
