As Michiganders, we take great pride in our trees. It’s no wonder people from other states flock to the mitten in the fall to witness the change of seasons. In our Westland yards, trees are a promontory feature that helps make our house feel like a home, which is why you should take tree diseases very seriously. 

Trees planted in lawns are much more vulnerable to the elements, pests, drought, and diseases. That is because, in the forest, the sheer number of other trees helps prevent one tree from getting too over-invested with pests. Trees help protect each other from violent winds, drought, and even diseases. In our yards, however, trees are unprotected and prime targets for pests and the diseases they carry.

Tree diseases are hard to spot and some can take years to begin to show symptoms but if they aren’t treated in time the entire tree could be lost. Check out this list of common and deadly tree diseases found in Westland, Michigan.

Tree Cankers

Tree cankers are caused by a fungus that infects wounded or stressed trees. Symptoms include oozing sap, discoloration, sunken areas. Keep your trees healthy and stress-free to reduce the chances of tree cankers. If your Westland trees have cankers, the infected areas should be pruned. Do not prune during wet or humid weather as this can spread the fungus to other branches or trees. Always sterilize your equipment after use.

Oak Wilt

Oak trees are known for their strength and durability but even mighty oaks are vulnerable to tree diseases. Oak wilt is caused by a fungus that hitches a ride on sap-feeding beetles. These beetles are attracted to the sweet sap that leaks out of wounds in oak trees which is why it is vital that you prune only when the tree is dormant in early spring or late fall. Oak wilt is a fast-moving lethal fungus that can kill a red oak in four to six weeks and white oaks in one to six months.

Needle Cast

Another tree disease common in Westland and Michigan is the Rhizosphaera Needle Cast. Needle cast is a foliage disease that affects spruce trees. The blue spruce is not native to Michigan, making it susceptible to diseases outside of its habitat. The most obvious symptom of needle cast is branch dieback. It begins in the inner lower branches and works its way out to the rest of the tree over several years. As the disease progresses, the tree will look thinner and thinner each year until enough needles are lost, and the tree eventually succumbs. To identify needle cast, look for lines of small black dots along the surface of the needles. Fungicides may effectively control the disease, but removing all infected trees before it spreads is the best option.

Anthracnose

Anthracnose is one of Michigan’s most common tree diseases and can infect oak, maple, ash, sycamore, and many other species. The fungus creates dead spots on leaves that disrupt the photosynthesis process. This can lead to early defoliation, which can stress the tree and make it vulnerable to other diseases. Anthracnose continues to spread each year and can severely damage or stunt the growth of the tree. Signs of anthracnose can be seen In the late fall and early spring as black bumps on leaves. Spores are released and dispersed by wind or rain to other branches and nearby trees.
