If there are Douglas firs in the area, check to see if they are experiencing problems. On Douglas fir, the bottoms of needles develop white, cottony galls in the spring and needles may become splotch yellow or deformed. The pest moves between the two trees and the populations are higher. Cooley spruce gall can be more severe if there is a Douglas fir in the vicinity. Prune green, closed galls and destroy them by burning or burying to control the population. If the galls are brown and have holes in them in the fall, you can prune off the gall, but it will not control the population. By mid- to late summer, lemon-shaped holes appear in the galls and the new adelgids run off to hide other places on the tree. Galls begin green and age to a rosy color. The immature adelgids feed on the tissue in that area and a gall made by the blue spruce forms around them. It is actually caused by the small adelgid laying eggs at the base of the bud at the end of the branch. Others mistake it for a green spruce cone. At the end of the twigs, a swollen bulge appears and grows. This is a gall that is only found on blue spruces. These galls are caused by tiny, aphid-like insects called adelgids.

If the apples or crabapples become partially defoliated because of cedar-apple rust, consider using an appropriate fungicide. When the leaf is flipped up to expose the back, little tentacles or protuberances hang down from the spot. The leaves will display bright yellow, orange and red spots on the leaves. On apples and crabapples, their problems appear later in the season. For Eastern red cedars, the galls do not seem to create much of a health concern. With the warm rains, orange, slimy projections called telial horns grow out of the gall. It is never perfectly round, but is misshapen. It could be the size of a small marble to occasionally as big as a golf ball. On cedars, a small woody gall remains all year. Just as the name implies, it is a disease that needs two partners to happen: Eastern red cedars and apples or crabapples. With the first warm rains of spring, little deformed, woody galls on Eastern red cedar twigs sprout orange, slimy projections that make them appear to look like an orange octopus or a big, wilted asterisk. Fungicides are rarely effective to prevent black knot. Galls on the main trunk cannot be removed without doing a great deal of damage. Galls should be pruned out during the winter.

This is a chronic problem on plums.ĭo not prune during the growing season. During the second year, the galls turn black and corky. During the first year, growths on the twigs are tan, smooth and velvety and difficult to spot. Eventually, the branch dies because the flow of nutrients is cut off at the gall. The gall often deforms the branch and causes it to elbow or bend in the vicinity of gall. Occasionally, this is found on cherries.īlack, corky, bulging galls are found on small branches. Wild plums like Canada or American also can fall victim. Edible plums like Stanley and Shropshire are very susceptible and others are moderately susceptible. If you have decorative plum trees with names like purple leaf plum, sand cherry or edible plums, they can develop a problem called black knot. What is that peculiar growth that has no business being there? Michigan State University Extension takes a look at several of the usual suspects. As people are strolling around examining their landscape plants this late spring, many have stopped short and gasped at what is on their tree or shrub.
