Why are my dogwood leaves drying up?

Cause: Dogwood has shallow roots and doesn’t like long periods of hot, dry weather. If it dries out even for a single day, the outermost leaves will scorch and stay that way or drop. If this isn’t severe, the tree will recover. If you see wilting leaves in morning, water the tree immediately and thoroughly.

Can you overwater dogwood trees?

Virginia Tech tree authority, Bonnie Appleton at the Hampton Roads Research Center, said, “Overwatering could cause problems with dogwoods. They don’t like wet feet, and that could predispose the trees to other things, like anthracnose.

How do you treat a sick dogwood tree?

Remove the infected tree and do not replace it with another woody ornamental until the soil has been fumigated and aerated. Apply a fungicide to protect plants.

Why are the leaves on my dogwood tree turning white?

On dogwood trees, Mycrosphaeria pulchra is the causal pathogen for powdery mildew. This disease causes a white, powdery coating on upper leaf surfaces. As the disease progresses, the leaves may cup or curl upward. If you see the white coating and cupped leaves on your tree, fungicides cannot cure the disease, which is already established.

Why do dogwoods curl their leaves in the summer?

Leaf curl on dogwoods is essentially a protective reaction to stress the tree feels. Rather than keep its leaves flat and susceptible to burning in the summer sun, dogwoods curl their leaves to minimize leaf surface area and thus minimize any damage they might receive.

What should I do if my dogwood tree is dying?

A more attainable goal is to manage the environmental influences that favor the disease. Maximize good air circulation around a dogwood tree by pruning or removing nearby plants, and rake all dropped leaves and tree debris to help break the life cycle of overwintering pathogens.

What can I do about powdery mildew on dogwood tree?

If you’ve opened the canopy and powdery mildew persists, try spraying your dogwood with neem oil concentrate, mixed at a rate of 2 tablespoons per gallon of water. Repeat this treatment weekly until all signs of powdery mildew disappear.
