Turfgrass, trees, and shrubs are desired in most landscapes because they are attractive and useful. Unfortunately, growing turfgrasses in the presence of trees and shrubs can be a formidable task because each plant group competes with the other for the light, water, and nutrients that are essential for survival and growth. The desired effects of trees sometimes make it difficult to grow turf. When trees and shrubs are used to provide screening and privacy, the reduced wind movement and sunlight often increase the chance for disease. Even so, homeowners can take steps to improve the performance of a lawn growing in shade.
Follow the suggestions and BMPs described in this publication to reduce sediment and keep nutrients and pesticides applied to turf from contaminating North Carolina's water resources.
Recommended maintenance practices for a lawn that consists of a blend of tall fescue, hard (fine) fescue, and Kentucky bluegrass are the same as those for a tall fescue lawn. The following management practices will help you care for your lawn throughout the year.

Lawns are ecosystems that impact surface and groundwater systems. The grasses found in lawns clean the environment by absorbing gaseous pollutants and intercepting pesticides, fertilizers, dust, and sediment. Irrigation water properly applied to lawns remains on site to recharge water supplies. In addition, grasses release oxygen and reduce glare, noise, and summer temperatures. Proper management practices need to be developed and followed to protect this environment. The purpose of this publication is to provide you with management strategies to preserve and protect water resources.
This publication will help you care for your lawn in ways that prevent and reduce contamination of our water resources by sediment, fertilizers, and pesticides.
Although groundwater and surface waters are rarely polluted by turfgrass pesticides, turf managers should consider the potential for environmental contamination when choosing a pesticide.
This guide to lawn maintenance for North Carolina contains information on establishing a new lawn, maintaining it, and controlling lawn pests using organic methods. It also provides information on renovating an existing lawn.
While research has shown that pollution of surface and groundwater supplies from turfgrass pesticide application is uncommon, the turf manager should still strive to avoid potential environmental contamination when choosing a pesticide.
Proper application of pesticides and fertilizers, which protects water quality, is possible only with a sprayer or spreader that is accurately calibrated. Pesticides applied with equipment that has not been calibrated may be misapplied by more than 10 percent. That may lead to repeat applications, damaged plants, excess cost, and contamination of the environment.
