Plant and Insect Diagnostic Clinic Update - August 8, 2007

Samples with the following problems have been seen in the Clinic lately:

Decline of trees

Environmental stress on many plant

Fusarium root and crown rot of hosta

Minor leaf spot diseases of maple: tar spot and leaf blister

Hey, who splashed tar all over the leaves of my lovely maple tree?

Transplanting peonies

Peonies can be left undisturbed in the garden for many years. Occasionally, however, it becomes necessary to move established plants. Peonies shaded by large trees or shrubs should be moved to a sunny site to improve flowering. The redesign of a perennial bed or border may require moving the peonies. Large, vigorous plants can be dug and divided for propagation purposes.
