Indian Hawthorn problem
Something is destroying my Indian Hawthorns. For years they have looked great and this year was no exception.....until a few weeks ago. Something (caterpillars) have made hunderds of what look like cocoons on a few of the plants. Two others look fine. The "cocoons" are brown and white in color and are 1"-2" long. What are they and how do I get rid of them.
