“… have you ever wondered how insects and plants relate to one another? In some ways they are partners; in other ways they are enemies.” D.H. Patent, Plants and Insects Together, 1976.

One of the most popular reference questions we receive at the Weston Family Library has to do with identifying, treating and preventing pests and diseases in the garden. These problems can leave even the novice gardener stumped.
