Overview
Uses
Reproduction
Cultivation
- Cottonwoods need a location with full sun and lots of moisture. They grow particularly well along lakes and rivers as well as in marshy areas. The trees prefer sandy or silty soil, but will tolerate most anything but heavy clay. They are hardy in USDA plant hardiness zones 2 through 9.
Issues
- Planting cottonwood trees in home landscapes leads to problems. These messy trees have weak wood and are prone to disease. In addition, their massive size makes them out of scale for all but the largest landscapes.
Benefits
- Cottonwood trees are the fastest growing trees in North America. A young tree can add 6 feet or more in height each year. This rapid growth leads to weak wood that is easily damaged.
Description
- The trees can grow to well over 100 feet tall, with eastern species sometimes reaching 190 feet. The canopy of a mature tree spreads about 75 feet wide, and the diameter of the trunk averages about 6 feet at maturity.
Management
- If you already have a cottonwood tree in the landscape, pruning may be necessary to control its growth. The best time to prune cottonwoods is late winter while the tree is dormant. Prune for proper growth while the tree is a young sapling. Its rapid growth soon puts the branches out of reach.
Prevention
- Always use clean pruners when pruning cottonwoods. The tree is prone to disease, and dirty tools can introduce bacteria, fungal spores and insect eggs into the pruning wound. Wipe them down with a cloth saturated with alcohol or a disinfectant cleaner, or dip them in boiling water.
Preparation
- Begin by removing all the branches from the lower one-third of the tree. Using long-handled pruners, make the cuts close to the trunk, cutting at an angle that slants down and away from the tree. Leave stubs of about one-quarter inch.
