Installing new sod can be an exciting project for homeowners, especially when it comes to enhancing the appearance of their lawns. However, knowing how to water different types of grass is essential, particularly in the Transition Zone, where the climate poses unique challenges. This guide provides detailed information on watering Bermuda, Zoysia, and Tall Fescue sod to help you achieve a lush, green lawn.
Understanding the Transition Zone
The Transition Zone is a unique area that lies between the cool-season and warm-season grass regions of the United States. This creates a mix of conditions that can make lawn care tricky. In fact, homeowners in this area may experience extreme temperatures, ranging from high heat in summer to colder conditions in winter. Therefore, understanding the specific needs of your sod type is crucial for successful establishment and long-term health.
Proper irrigation practices not only promote grass health but also conserve water and improve lawn sustainability. By being informed, you can maintain a vibrant lawn while contributing positively to the environment.
General Watering Concepts
In-Ground Irrigation Systems
In-ground irrigation systems typically require professional installation but are an excellent method for effectively watering large areas. These systems can be set to operate on specific days and times, allowing for a customizable watering schedule during turfgrass establishment. Consider the following when scheduling watering programs for newly laid sod:
Mornings are ideal for saturating sod and allowing it to soak into the top 1/2 - 1 inch of soil due to reduced evaporation.
Although evenings offer similar benefits, irrigating new sod at this time can increase the risk of disease.
Mid-day to early afternoon is when new sod is most likely to dry out. Scheduling a mid-day irrigation during the first week after sod installation is the best way to counteract this effect.
As roots start to penetrate the soil, making the sod hard to lift, this indicates that irrigation duration and frequency can be decreased.
Ensure proper water coverage, especially at corners and edges.
Hose-End Sprinklers
Hose-end sprinklers vary in quality and output, but their portability and affordability make them a suitable option for watering newly laid sod. Using hose-end timers and multiple outputs can reduce the labor-intensive nature of this watering method. Consider the following when using hose-end sprinklers for newly laid sod:
Output and coverage differ significantly by nozzle type, so choose equipment that provides adequate water volume and pattern for your new sod.
Hose-end sprinklers with larger droplet sizes will minimize water evaporation during irrigation, which is crucial for midday watering.
These sprinklers often need to be manually repositioned several times a day to cover all newly laid sod, especially in large or irregularly shaped areas.
Hose-end sprinklers should follow the same timing, frequency, and adjustment guidelines as in-ground irrigation systems.
Watering Needs for Bermuda Sod
Bermuda grass is a hardy warm-season grass known for its heat and drought tolerance. Nevertheless, newly installed Bermuda sod needs consistent watering to establish strong roots.
Initial Watering
After laying Bermuda sod, it's essential to water it thoroughly to ensure the soil underneath is moist. Aim to soak the top 6 to 12 inches of soil, which may require 30 to 60 minutes of watering, depending on the soil's drainage ability.
When to Water:
Morning: Water Bermuda sod between 6:00 AM and 10:00 AM. This allows the grass to absorb moisture before the sun's heat causes evaporation. This should be the largest water input of the day.
Mid Day: Water Bermuda sod between 1:00 PM and 3:00 PM to counteract evaporation. It's recommended to use half the water volume of the morning event.
Tip: Avoid watering in the late afternoon or evening, as excess moisture can promote diseases by keeping the grass wet overnight.
Continued Watering Approach
For the week after root establishment, water Bermuda sod deeply every other day, while adjusting based on the weather. You may need to water more often during hotter periods.
Generally, 0.5 to 0.75 inches of water during any rolling 7 day block should suffice. In peak summer months, monitor and water at the higher end of this scale as needed to combat heat stress and evaporation.
Mowing Guidelines
Wait until Bermuda grass reaches around 2 inches in height before the first mowing. Mow during cooler times of the day, ideally in the early morning or late afternoon. A mowing height of about 1 to 1.5 inches will maintain your lawn's health and promote denser growth.
Watering Requirements for Zoysia Sod
Zoysia grass is another warm-season option well-suited to various soil types and provides excellent drought tolerance. Newly laid Zoysia sod, however, has specific watering needs to boost its establishment.
Initial Watering
Immediately after laying Zoysia sod, water thoroughly to ensure the soil underneath remains consistently moist.
When to Water:
Morning: Water Bermuda sod between 6:00 AM and 10:00 AM. This allows the grass to absorb moisture before the sun's heat causes evaporation. This should be the largest water input of the day.
Mid Day: Water Bermuda sod between 1:00 PM and 3:00 PM to counteract evaporation. It's recommended to use half the water volume of the morning event.
How much to water:
Your irrigation needs will vary based on the structure of your soil, composition, organic matter content, and soil pH. The following are general instructions for the most commonly found conditions in Northeastern Oklahoma's transition zone.
Morning: Add 3/4 to 1 1/4 inches of water. If water begins to runoff prior to achieving this volume, then inserting a 20-30 minute break before completing the irrigation event is recommended.
Mid Day: Add 1/4 to 1/2 inches of water. If water begins to runoff prior to achieving this volume, then inserting a 20-30 minute break before completing the irrigation event is recommended.
Ongoing Watering Strategy
For the initial 2 to 3 weeks after root establishment, water Zoysia sod deeply every other day, while adjusting based on the weather. You may need to water more often during hotter periods.
Generally, 1 to 1.5 inches of water during any rolling 7 day block should suffice. In peak summer months, monitor and increase watering if necessary while ensuring proper drainage to avoid yellowing.
Mowing Recommendations
Do not mow Zoysia grass until it reaches around 2 to 3 inches in height. For optimal health, maintain a mowing height of 1 to 2 inches, which also helps to suppress weed growth.
Watering Requirements for Tall Fescue Sod
Tall Fescue is a cool-season grass recognized for its resilience and ability to adapt. Its deep roots make it suitable for the Transition Zone, but managing its watering is key.
Initial Watering
After installing Tall Fescue sod, water it thoroughly, ensuring the soil beneath is moist.
When to Water:
Morning: Water Bermuda sod between 6:00 AM and 10:00 AM. This allows the grass to absorb moisture before the sun's heat causes evaporation. This should be the largest water input of the day.
Mid Day: Water Bermuda sod between 1:00 PM and 3:00 PM to counteract evaporation. It's recommended to use half the water volume of the morning event.
