Regional Notes

Trees show witches' brooms, stunted growth, small deformed fruit, and late bud break in fall. This phytoplasma disease has no cure available to home gardeners. Infected trees may appear to recover but still carry the pathogen. Remove infected trees.

Send any trees that may have these symptoms to a diagnostic lab for confirmation of the disease, and never smuggle in budwood or trees. Always use certified planting material.
