One of the most common warning signs of Dogwood Anthracnose is telltale black, brown, and even reddish lesions on the leaves. Although it can vary in appearance from one tree to the next, it is still a disease that can cause irreparable damage to your cherished dogwood. The most important key to controlling this disease is timing. The sooner that we can diagnose it, the quicker we can treat it.
The most common symptom of Dogwood Anthracnose is discoloration of the foliage along with the appearance that the tree is wilting. Foliage will begin showing dark blotches in-between or along the length of the leaf vein. In severe cases, the tree will begin to defoliate and experience an earlier than normal leaf drop.
Phytophthora Root Rot
Although Phytophthora looks similar to a fungus, it is not. It is related to brown diatoms and algae, but it can grow on land without water. Technically, it is an organism that is considered a water mold, but it doesn’t need water to survive. Phytophthora root rot can appear in ornamental trees, mature trees, and any shrub. This is one of the most common diseases we see in the landscape.
If a plant has a Phytophthora infection, the leaves will often appear stressed and dried out. It is common for the leaves to turn a dull green, red, purple or yellow, while wilting. Also, the tree bark at the soil line will have a darker appearance. To check for infection, please schedule your free consultation today!
Phytophthora Canker is an infection that kills the outer sapwood tissues and bark of a tree or shrub. The most common sign of infection is a darkening of the sap that comes from the bark cankers.
The sap is a red-brown color that stains the outer bark of the tree. It does not work by causing decay of the wood itself, it consumes the sugars of the outer sapwood and cambium. Therefore, the biggest threat of a Phytophthora Canker infection is that it can provide a site for an infection for wood-rotting fungi to do a whole lot of damage.
Seiridium Canker is most common on Leyland Cypress and other species of cypress. The most common sign of infection is yellow to red-brown flagging (dead branches in the middle of healthy canopy) that will begin to appear on a seemingly healthy tree. When you look closer, you will often notice resin coming from the cankers themselves. The Cankers are typically located lower on the branch, closer to the trunk, and on the shoot tips.This is the most common cause for decline and death of Leyland Cypress.
Fungal Leaf Spot and Shothole Disease
We all love flowering cherry trees. They are a staple tree for this region of the United States. However they, along with many other trees are very susceptible to fungal leaf spot and shothole disease. Leaf spots typically begin as small specs on the surface of the leaf. Shothole disease looks like the leaf was shot with a shotgun. Small holes covering the surface of the leaf. Over time, the spots will turn red-brown, and eventually, they may appear to be gray. If left untreated, typically the leaves will begin to drop, and the tree will defoliate.
