Proper irrigation is crucial for maintaining a lush and healthy lawn. However, the watering schedule and techniques you should use depend on the type of soil and grass in your lawn. In this article, we’ll provide irrigation tips for customers with cool season grasses like tall fescue and Kentucky bluegrass in Billings, Montana, focusing on those with normal draining soils and clay soils.
Normal Draining Soils
If your lawn has normal draining soils, it’s best to water every other day, preferably in the mornings between 4-8 am. This timing allows the grass to dry during the day, preventing diseases that thrive in moist conditions. Be mindful not to water too late in the evening or at night, as this can create a damp environment that is conducive to disease.
When watering, make sure to apply enough water to reach the grass’s root zone. Typically, you’ll need to water for 20-30 minutes, depending on your sprinkler system’s output. However, avoid overwatering, as this can lead to root rot and fungal diseases.
For lawns with clay soils, water less frequently but for longer periods to prevent pooling. Water every 3-4 days, but adjust based on weather conditions and the grass’s water needs. If the ground is still wet after 4-6 days, you can delay watering.
When watering clay soils, use a slower application rate to allow water to penetrate the soil. You may need to switch out nozzles on gear-driven heads like Railbird 3500’s and 5500’s to achieve a slower application rate.
Cool season grasses like tall fescue and Kentucky bluegrass require regular fertilization to maintain their health and vibrancy. However, customers with clay soils and more alkaline soils may experience iron deficiencies, leading to yellowing grass.
