Leaves would have dropped anyway, but the stress release because of precipitation may have synchronized the leaf drop, causing the sudden loss of so many leaves. Mulberry trees often exhibit synchronized leaf drop after a hard freeze in the autumn.

Your irrigation practices apparently are sufficient to maintain the trees, but I have some suggestions. Remember the cottonwood trees are trees that perform best when there is consistent moisture in their root zone.

This root zone extends from the tree outward to at least four times the height of the tree. The roots most actively absorbing moisture are the very small root hairs and hair roots that are found in the region under the drip line and outward to the end of the root system as much as four times the height of the tree away from the tree. The more of this region in which you can maintain moist soil, the better the tree will grow. Absorptive roots of trees are most common in the top one foot of soil where they are in competition with grass roots.

Grass roots are more efficient at absorbing precipitation and irrigation water than tree roots and compete with the trees for the water. This explains why the grass is doing well while the tree is losing leaves.

The trees have deeper roots that allow them to compete more effectively compete with the grass. James Klett discusses the history of PlantTalk Colorado.
