Q.Pruning knockout roses late in Spring
I live in western SC. I have many knockout roses that are a year old. In mid March I cut them back, but after seeing the regrowth realized I didn’t cut them back enough due to where I placed them. Listening to my husband, I decided to cut them back again and this time about 12″ off the ground. These roses I cut were healthy and very showy. I’m afraid I cut too much and too late in the season. What should I look out for if they start to die? Will they grow back with blooms this season? I’m depressed because they were so pretty. (I won’t listen to my husband next time)
Don't be too upset. This has happened so many times I cannot count them all on my fingers and toes! The rosebushes should be just fine. It will take them a bit to get the new growth and setting of buds going but they should give you some nice bloom smiles yet again this season. I recommend mixing some root stimulator of choice and a product called Super Thrive in a big watering can and water each of the rosebushes with that mix. About a gallon to each rosebush. This will help get the growth and setting up buds going more quickly and also relieve any shock they may be dealing with. About a week after giving them this mix, give them some good organic rose food too and water them well.
