Cottonwoods are ubiquitous in Colorado. Those huge branches hanging over your house must have the dead wood trimmed out. Also, your insurance company, especially at the time of a real estate transaction, may request that you remove a cottonwood too close or hanging over the house. Obviously the actuarial tables they keep are telling you something about the hazards of a cottonwood tree.
Cottonwood Plant Heath Care
Typically cottonwoods are pretty resilient. They may require a good fertilization and spraying for aphids. Cottonwood roots love to run along the surface of the soil. They do this for oxygen and water.
Removing a Cottonwood
Over half of the dangerous trees we remove are cottonwoods and they are the costliest to remove. It’s a good idea to plant a more desirable tree species close to a cottonwood and remove the cottonwood before it gets too big to remove economically. That way you will have a tree to replace the canopy you lose by removing the cottonwood, but don’t get locked in to keeping the cottonwood too long.
