Why is my dogwood leaves turning yellow?

Yellow foliage (chlorosis) on dogwood is often a sign of iron deficiency.

I suspect that is the problem with your tree.

How do you save a sick dogwood tree?

Prune and destroy dead wood and leaves yearly; prune trunk sprouts in the fall. Water weekly in the morning, during drought. Caution—do not wet foliage. Maintain a 4- to 6-inch deep mulch around trees; do not use dogwood chips as a mulch.

How do you treat a diseased dogwood tree?

Fungicide sprays to protect the new leaves and shoots need to begin at bud break in early spring. Fungicides for spot anthracnose will also help to control dogwood anthracnose. These include chlorothalonil, mancozeb, propiconazole, thiophanate-methyl, or copper fungicides (see Table 1 for specific products).

How do I know if my dogwood tree is dying?

Examine the bark at the base of the tree and at the base of the larger branches. Peeling bark is a sign of disease and death. If the bark has peeled away -- or flakes away with no effort -- around the girth of the branch, then that branch is dead.

What kind of fertilizer do dogwood trees like?

Dogwood trees grow well with a 12-4-8 fertilizer ratio. The abundance of nitrogen, denoted by the first number, reflects this element's importance to the tree. Nitrogen provides the basic structure for chlorophyll, the main pigment necessary for photosynthesis within the leaves.

What is wrong with my dogwood?

Crown canker, Phytophthora cactorum, is the most serious disease of flowering dogwoods in the Eastern United States. ... Though not always noticed, the cause of the problem is a canker (dead area on the lower trunk or branches) that is slowly girdling the trunk and killing the cambium.

What causes dogwood tree leaves to curl?

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.

How long do dogwood trees last?

A: In perfect growing circumstances, a dogwood tree can last several decades. But in spots where the roots get hot or dry in summer and where grass competes for moisture and nutrients, dogwoods typically have a 20- to 30-year life span.

Why are the tips of the leaves on my dogwood tree turning brown?

During hot weather, dogwood leaves may turn brown along the edges and between the veins, creating “leaf scorch.” Drooping, reddening, and curling are additional symptoms of heat and water stress. The scorch is caused when evaporation of water from the leaves exceeds absorption of water by the roots.
