We
have had another relatively mild winter, so watch for defoliation of
honeylocust trees from mimosa webworm this summer in southern Michigan.
If you are planning on protecting them, watch for patches of foliage
that turn brown in late June. Spray when you see the first signs of
brown foliage, webbing and caterpillars. Last year, many trees turned
completely brown before the webworm was found.
