Answer: Roses need lots of sunshine and ample water. A sprinkling every couple of days won't keep them healthy. You'll want to soak the root area once a week to make sure they're getting enough water. Set a sprinkler under them and let it run for about 15 minutes. Do this once a week when the weather is mild, twice a week when it's hot. The Japanese beetles will stop feeding in a couple of weeks. At that time you can prune off the damaged parts of the plants and healthy new growth will be produced.
Best wishes with your roses!
