Drought conditions have led to stress in established trees and difficulty starting young trees. With the need for supplemental watering, correct irrigation practices are important to tree health and efficient water use.

Fall is tree planting time and an important time to water established trees in the absence of adequate precipitation. Whether a new tree or an established tree, correct watering is important. Too little as well as too much water can lead to tree stress, a decline in growth, and water waste.

Tall fescue tolerates dry periods better than KBG due to a deeper root system that uses moisture deeper in the soil. However, it does not have the physiological ability to go dormant to avoid dying from drought. If tall fescue begins to turn off color from a lack of water, it requires irrigation.

When we think of stormwater runoff we often think of rain. Snow melt during winter can also become stormwater runoff and carry pollutants to surface water. During winter the ground is usually frozen and melting snow cannot infiltrate into soil as a light rainfall will do. Depending on the amount of snow, this can lead to increased runoff during winter.

Phosphorous is an essential plant nutrient. Phosphorous can also lead to impaired water quality in surface water like lakes and ponds. Applying phosphorous responsibly is important to turfgrass growth and to water ecosystems.

Lawns need about one inch of water per week. During the hottest part of summer, they may need one and a half inches. Do you know how much water your irrigation system applies? Lawns require uniform watering so one area is not under watered while another is overwatered. Do you know if your system waters uniformly? Lawns are best watered deeply but infrequently. Do you know what this means and if you’re watering program meets this recommendation?
