The temperature gauge has been steadily reading “HOT” in Idaho and the summer heat is beginning to take its toll on our lawns. Most Treasure Valley lawns prefer temperatures in the 60’s and 70’s and when daily temperatures are in 90’s and above they begin to shut down to protect themselves resulting in brown patches and an influx of weeds.
High heat can be brutal on lawns, especially if they are thin or unhealthy already. Hot soil leads to crabgrass germination which loves the hot and dry weather that are typical of July and August in Boise, Idaho. Other heat-loving weeds such as oxallis, spotted spurge, and black medic will pop up and quickly fill in thin or bare spots in your lawn.
The best way to keep your lawn healthy and the weeds at bay begins in the Spring when you can apply a pre-emergent and broadleaf weed control. But if you failed to do this there are some measures you can take in the summer to contain the weeds and contribute to a healthier lawn.
One of the issues we see often in the Treasure Valley is issues with irrigation. Over watering and under watering both cause damage to your lawn and it is important to remember that deep infrequent watering is best. Most grasses need an inch of water per week and in the peak of summer they may need more. It is a good idea to measure the amount of water your sprinklers are putting out to determine how long they need to run to provide just the right amount. One simple way to measure your water is to put an old tuna can out and see how long it takes to fill up.
Besides inadequate watering, mowing your lawn too short is another practice that puts your grass at risk. In the heat of summer you should keep your grass at 3 inches. Any shorter and you are compounding the stress that the summer heat is already putting on your lawn.
Someone said to think of summer as a time to get your lawn through a bad cold or flu. The idea being to do all you can to prevent as much damage as possible from weeds, insects, and disease while your lawn is in an already vulnerable state.
