The Q&A Archives: rose problem

Question: What can I put on my roses to keep them from the leaves being stripped totally. I have never had this problem before. I roses keep getting stripped of their leaves. I was told to use 7 dust, and I do but that only seems to work for a few days. I have to put the 7 dust on every 4-5 days, if not raining to keep them from being stripped, when new growth appears. They seem to be destroying my tree roses more than the other rose bushes. Any sujestions? Thanks for your help. I love roses, and have roses all my house. So what is stripping my roses and what can I do for them? They look pitful!!

Answer: I'm not sure that an insect is stipping the leaves of your roses. The damage sounds more like deer feeding. If the tender leaf is gone but the center vein is still there, deer are the likely culprits. However, if you can see definite holes in the leaves and/or frass (caterpillar droppings), the problem is insect related. Closely inspect the leaves for eggs, frass, worms or bugs. What you find will determine the control measures you'll need to take. Sevin will knock out most insects, including bees, so I wouldn't use it regularly in the garden. Not only can you kill the honeybees, you can also kill the beneficial insects that may have come to prey on the destructive insects in your garden. If caterpillars are feeding on your rose leaves you can use Bt (bacillus thuringensis) which targets only caterpiller worms. It is sold as Dipel in the garden centers. Apply according to label directions.

Best wishes with your roses!
