The Q&A Archives: Dying Knockout rose bush

Question: My Knockout rose bushes seem to be dying. The leaves are falling off and they have brown spots on them. What can I do to prevent this.

Answer: Knock Out roses are some of the most problem free roses around so I'm not sure what the problem might be with yours. They need to be deeply watered once each week. Try pruning them down to get rid of the affected stems and leaves. New growth should be healthy. Water them well once a week and I'm sure you'll see an improvement. Best wishes with your roses!
