Summer is a very stressful time for your lawn. The combination of the beating sun and heat, increased foot traffic, water deprivation, weeds, and pests can be detrimental to the health of your lawn. Because of this, Americans spend about $8.5 billion on lawn care services each year. No matter how much you spend, these factors can combine to leave you with yellow patches or even turn your grass brown under the heat and stress of summer. A brown lawn doesn’t necessarily mean dead grass, though; cool season grasses go dormant in the summer, turning brown as a defense mechanism against the heat and turning green again when they are revitalized in the cooler weather of fall. Nonetheless, there are some things you can do to ensure a lush green lawn despite the heat. Check out these lawn care tips to keep your grass green this summer.
Mow high in the summer months. Grass should be left about 3 inches tall as this provides more shade for the root system and keeps it cooler in the summer. Leaving the blades taller also encourages the grass to develop stronger, deeper root systems. Mowing should be done in the early morning or early evening to avoid the peak daytime heat. Make sure your mower is kept in good repair, as well. A poorly maintained mower can do more damage than good to your yard. Make sure mower blades are sharpened – dull blades tear the grass versus cutting it which can leave brown tips on the grass blades. Make sure the oil, filters, and spark plugs are changed, as well.
Know when your lawn needs watering. You can usually tell grass is ready for a drink when it turns a bluish-gray color or if it stays matted down when you step on it rather than springing back up. Be mindful of how often you water, as well. Be mindful of any drought restrictions in your area before you water. Watering should be done consistently and deeply once or twice per week rather than a shallow watering daily.. Your lawn only needs 1 to 1-1/2 inches of water per week to keep its green color. Water early in the morning so that your lawn has time to dry out over the course of the day. Watering in the evening leaves dampness in the soil overnight that can lead to fungal disease. Don’t water your lawn with hot water. Don’t leave your garden hose out with water in it as this water can get hot enough to scald the grass blades in your lawn. Always empty your garden hose after each use; if you forget, make sure you flush the hot water out before you start watering.
Cool season grasses go dormant in the summer so you should wait to fertilize those in the fall. Fertilizing in the summer can trigger new growth which will ultimately turn brown. Warm season grasses should be fertilized every 6 weeks. If this causes your lawn to grow too quickly, switch to a fertilizer with a lower nitrogen content to slow the growth. Using a mulching mower can also help to naturally fertilize your lawn by recycling the nutrients in grass clippings back into the soil. Fertilizer should be applied evenly and judiciously. Too much fertilizer can also turn your lawn brown.
Maintaining your lawn can also help preserve its green color in the summer. When your pets do their business on the grass, they are essentially over-fertilizing that area with the additional nitrogen in their urine. If you notice yellow or bare patches where your pets often go, overseed them to keep them in good repair. Summer also brings extra foot traffic on your grass. Heavy foot traffic, especially on wet soil, can lead to soil compaction which prevents air from getting to the grass roots. Try to avoid walking on the grass as much as possible.
