Summer can be tough on your lawn, with the heat taking a toll on your grass. But with the right watering techniques, you can keep your lawn healthy, green, and thriving, even during the hottest days. It’s all about understanding what your lawn needs, and making a few simple adjustments to your watering routine. Here’s how to do it.
Understand Your Lawn’s Water Needs
The first thing you need to know is how much water your lawn actually needs. Most lawns need about 1 inch of water each week, which includes any rain that falls. But, during extreme heat or dry spells, your lawn may need a little extra. The amount of water your lawn needs can also depend on the type of grass you have. For example, warm-season grasses, like Bermuda or Zoysia, are a bit more drought-resistant than cool-season grasses, like Kentucky Bluegrass or Fescue. By knowing what type of grass you have, you can adjust your watering schedule to suit its needs.
Watering the right amount is important. If you water too little, the grass will dry out and turn brown. If you water too much, it can cause problems like fungus or root rot. Finding that balance is key to keeping your lawn healthy.
Water Deeply and Infrequently
When it comes to watering, deep and infrequent is better than shallow and frequent. Shallow watering, where you just sprinkle a little water every day, encourages the grass roots to stay close to the surface. This isn’t good, especially during hot weather, because it means the roots can’t get to deeper, cooler moisture when the surface dries out.
Instead, you want to water deeply, so the moisture gets to the roots. Watering less often, about 1-2 times a week, will help your grass grow strong, deep roots that can survive the heat and drought. Aim to deliver about 1 inch of water per session, which you can measure by placing a few small containers, like tuna cans, around your lawn and checking when they fill up. This ensures that the water is soaking into the soil properly, rather than running off.
Water at the Right Time of Day
Timing your watering is just as important as how much water you give your lawn. The best time to water is early in the morning, between 5 a.m. and 9 a.m. This is when the air is cooler, and the winds are lighter, so you lose less water to evaporation. Watering early gives your grass a chance to soak up the moisture before the sun gets too hot. Plus, it helps prevent fungal diseases because the grass dries off during the day.
If you can’t water in the morning, try watering in the evening, but don’t do it too late. If the grass stays wet overnight, it can promote fungus and other problems. Watering during these cooler hours gives your lawn the best chance to thrive.
Monitor Soil Moisture
It’s important to keep an eye on how moist your soil is. Even if you have a set watering schedule, sometimes your lawn may need more or less water depending on the conditions. You can check the moisture level by using a moisture meter or simply sticking a screwdriver into the ground. If the soil feels dry several inches down, it’s time to water.
But, it’s also important not to overwater. If the soil feels wet even after a watering session, or if water is pooling on the surface, it could be a sign that you’re watering too much. Overwatering can lead to problems like root rot or fungal diseases, so it’s important to find the right balance.
Know Your Soil Type
Your lawn’s soil type plays a big role in how much water it needs. Sandy soils, for example, drain quickly and need longer watering periods. If your lawn has sandy soil, you may need to water a little longer to make sure the water soaks in deep enough. Clay or loamy soils, on the other hand, hold onto moisture for longer, so they don’t need as much watering. By knowing your soil type, you can adjust your watering routine to suit the conditions.
Avoid Overwatering and Underwatering
Overwatering and underwatering both cause problems. If you overwater, the grass can get weak, and diseases can start to spread. On the other hand, if you underwater, the grass will dry out and turn brown. To avoid these issues, watch your lawn carefully for signs of stress.
If your grass starts to look yellow or patchy, it could be a sign of underwatering. If it’s too wet, or if you see fungus or moss growing, it’s a sign you’re watering too much. The key is to keep an eye on how the lawn looks, and adjust your watering as needed.
Special Care for Newly Installed Sod
New sod needs a little extra attention to help it establish strong roots. For the first 9 days, water your new sod twice a day—once in the morning and again in the evening. After about a week, reduce the watering to once a day. Then, after about 12-14 days, you can start watering once every few days, and eventually settle into the regular 1-inch per week routine once the sod is established.
By giving new sod extra care during its first few weeks, you’ll ensure that it develops strong, deep roots, making it much more resilient to the heat and drought.
Keep Your Lawn Cool
Sometimes, during hot weather, your lawn can still suffer from the heat even if you’re watering it properly. Overwatering, in particular, can increase the chances of fungal diseases. If you notice that your lawn is looking stressed, consider adding a light layer of mulch or top dressing to help cool the soil. Just be careful not to cover the grass too thickly, as this can suffocate it.
A thin layer of mulch can help keep the soil cooler, reduce water evaporation, and even prevent weeds from growing. But, as with everything, moderation is key. Too much mulch can have the opposite effect, so keep it light and spread it evenly.
Conclusion
Taking care of your lawn during the hot summer months doesn’t have to be complicated. By watering deeply and less frequently, using the right time of day to water, and monitoring soil moisture, you can keep your lawn healthy, green, and thriving all summer long. Remember to consider your soil type, the specific needs of your grass, and the weather conditions when adjusting your watering routine. And don’t forget about new sod—it needs a little extra love in the beginning. With these simple steps, you’ll be able to enjoy a beautiful, hydrated lawn, no matter how hot it gets outside.
