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.
Clay Soils
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.
Proper Fertilization
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.
To address this issue, you can do multiple applications of sulfur and consider using enzyme treatments that feed the soil and reestablish the 16 essential nutrients needed for healthy turf. This treatment can help prevent iron deficiencies and promote overall lawn health. Additionally, follow the manufacturer’s instructions carefully when fertilizing your lawn according to its needs.
Proper irrigation and fertilization are crucial for maintaining a beautiful and healthy lawn. Whether you have normal draining soils or clay soils, following the appropriate watering schedule and using the right techniques will ensure your lawn stays healthy and vibrant. Consider using enzyme treatments to promote overall lawn health and prevent iron deficiencies. With proper care, you’ll enjoy a lush, green lawn that you can be proud of.
Other tips:
- During hot and dry days in July and August, consider using a technique called syringing to cool the lawn. This technique involves irrigating the lawn for a short period of time during mid-day to cool the grass blades and prevent wilting.
- Regular fertilization is also essential for maintaining a healthy lawn. It’s recommended to fertilize your lawn at least once a year to provide the necessary nutrients.
- Additionally, mulching can help reduce the amount of fertilizer needed by up to 1/3rd. Mulching mowers do not typically add to thatch buildup and is an excellent practice for most lawns when mowed regularly. Irregularities mowing can lead to the need for dethatching, preemergent treatments, and over seeding.
- When it’s hot and dry, skipping a mow and raising the blade height can also help your lawn. This will allow the grass to retain moisture and better withstand the heat and drought stress.
By following these tips and understanding your lawn’s water and fertilizer needs, you can ensure your lawn stays healthy and vibrant throughout the season.
