My 1 year old plants have developed yellow and brown leaves on sections of the plant. I do not seem to find any spider mites or aphids. What should I do?

If you don't see insects, look for spots on the leaves and stems of your plants. Knock Out roses are relatively disease resistant, but resistant doesn't mean immune. Or, you might simply want to prune out the branches with the yellow and brown leaves. Knock Out roses will take any amount of pruning and spring is an excellent time to prune. Best wishes with your roses!
