What phytophthora root rot is
Phytophthora is a fungal disease that causes root rot and stem cankers on many landscape trees and shrubs.
It's most prevalent in clay soils that are poorly drained, and on sites that receive excessive irrigation — conditions that are common enough in Omaha-area landscapes with heavy clay soil.
Treatment and prevention
Fungicide treatments are available to suppress phytophthora once it's present in the landscape.
Beyond treatment, judicious irrigation and careful selection of plant species for sites prone to root rot are the keys to avoiding the disease in the first place — matching the right plant to the right soil conditions goes a long way toward preventing an infection.
