Question
My cherry blossom tree bloomed as usual this spring but after the blooms had fallen we noticed that every leaf had been eaten by some kind of bug. Each leaf was eaten to the stem...nothing left
What could have caused this and what can be done to prevent this happening next year. We live in the Boston ,mass. area

Answer
There are several caterpillar type insects that could have cause this. I would spray the tree with an insecticide called Orthene. This will kill any insect present, You will need to spray all the remaining foliage and the if the tree is large this maybe a problem. You can use a product called Bayer Advanced Tree and Shrub Insect Control. This is  applied to the soil around the tree and the roots will carry it to the stems and foliage and if an insect feeds on the foliage it will be killed. I am assuming that any fruit formed would not be eaten and this is an ornamental  cherry. Here is a web link to this product--check with your local garden type store for these products. http://www.bayeradvanced.com/tree-shrub-care/products/12-month-tree-shrub-insect...
