Symptoms of Dogwood Anthracnose
Though the origin of this disease is unknown, it has a crippling effect on the infected tree. Sprouts and young green stems are especially susceptible. First, anthracnose affects the leaves, then it travels to the twigs and finally, seeps into the branches.
Early symptoms include purple rims and tan leaf spots. Check underneath the leaves for small brown spots as they are the source of spores that will spread to healthy trees.
Girdling cankers will first appear on leaf nodes and result in twig dieback which has the potential to kill the tree if it reaches the trunk. When it comes to older trees, the wood under the bark will be dark brown if it is infected.
What to Do and What to Avoid
Consider planting disease-resistant cultivars of flowering dogwoods as they will remain healthier. Additionally, have the dying twigs and limbs of your trees pruned regualarly. Finally, during the fall be sure to remove fallen leaves.
Do not dig native trees from the woods and transplant them into your yard as it can introduce a disease that was not there before. Also be sure to avoid over-fertilization.
