Water stress is the most common cause, with heat stress coming in a close second. But, even though Knock Out roses are insect and disease resistant, there could be a pest problem. Make sure your plants are getting a deep soaking once or twice a week and inspect the leaves for spots or signs of insect activity. If you find none, concentrate on your watering practices. When the weather cools a little you can prune your roses back to encourage healthy new growth. Good luck with your roses!
