If you’ve noticed sawdust and a gelatinous substance at the base of your peach tree it sounds like you may have the Peach Tree Borer. The oozing sap is more severe in early spring as the sap starts flowing, but you’ll see signs of it now along with frass, a sawdust like substance. The peach tree borer is a common problem in our area and attacks not only peach trees, but any stone fruit. A stone fruit is any fruit with a hard center pit, in the Prunus family, such as peach, apricot, nectarine, plum and cherry. It will attack ornamental trees as well so keep an eye on your flowering cherries and flowering plums, too.
