Carpenter Ants in Trees

Carpenter ants have been one of our most common and annoying pests during the past several years. Though we usually think of carpenter ants as a household pest, they are regularly encountered in the landscape as an "occupant" of trees.

Carpenter ants commonly nest inside older trees that are hollow or in trees that have dead limbs and branches. The nests are in rotted, decayed wood, although some nests may extend into sound heartwood in the center of the tree.

Pruning Roses in the Spring

The upper portions of modern roses, such as hybrid teas, floribundas, and grandilfloras, typically winterkill due to exposure to low winter temperatures and extreme temperature changes. When the winter protection is removed from these roses in early to mid-April, gardeners should prune out the dead wood.
