How do I fix my dieback?

If dieback is a problem, prune out dead or dying branches and remove them from the site. Disinfect the pruning tool between cuts using 10% household bleach, 70% alcohol, or a disinfectant product.

Pecan tree fun facts:

Pecans reach maturity at about twelve years old and can live as long as 300 years! Non-grafted seedlings and native pecan trees often take 10 to 15 years to begin to produce fruit. Grafted varieties produce fruit in 5-10 years depending on variety.

Why do pecans turn black and fall off tree?

Pecan scab is caused by the fungus Cladosporium caryigenum. At first, the fungus forms small, circular, olive-green to black spots on leaves, leaf petioles and outer nut shuck. With time the lesions increase in size and become blackened and sunken in appearance.

At what age do pecan trees bear fruit?

The more precocious varieties may sometimes start production in 4 to 5 years. The less precocious varieties may take 8 to 10 years to bear. Non-grafted seedling and native pecan trees often take 10 to 15 years to begin production.

What causes a pecan tree to die?

Pecan trees that die from stress typically succumb to a combination of factors, including poor soil depth or drainage, lack of water, bearing too many nuts, freezing, poor management or disease. A pecan tree that is in trouble may not appear to be ill until it is too late.

When do you stop watering pecan trees?

Pecan trees must be watered at least every two weeks because a three-week drought is the most a pecan tree can withstand. If your pecan tree undergoes water stress during the late stage of its development, it can lead to a major drop in fruit.

How do you save a stressed tree?

One method of overcoming that is to remove the thatch and use wetting agents so that water is really available to the tree. Even letting the turf grow taller means that the water doesn't evaporate so fast, and that helps the water get through.
