How Do I Get Rid of Green Worms on My Rosebushes?
There are little tiny green worms on the underside of the leaves of my rose bushes. They eat at the leaves until they are gone. I have used a general spray that was recommended by a nursery to get rid of them, but it is not working. I had them last year too. I can't seem to get rid of these little green worms.
The most organic treatment would be to hand-pick the worms and drop them in a bucket of soapy water. If that's not a good solution for you, look for an insecticidal soap or insecticide containing neem oil at your local garden center. These products are often considered organic. Note: Insecticidal soap has to be sprayed directly on the worms to stop them.
You can also go with a more hard-core chemical solution, such as the insecticide called Sevin. Look for this and other products at your local garden center. Be sure to follow the directions on the packaging -- if you misapply these products, they won't work very well
