A lot of what you can do to minimize thatch production is to practice good lawn management. Here are some lawn maintenance tips that help prevent thatch:
Water deeply and infrequently. Instead of watering for a few minutes every day, water your lawn once or twice a week. Turn on your sprinklers for a longer time to compensate — about 15 minutes should be enough.
Fertilize responsibly. Don’t overfertilize! Fertilize your grass with a slow-release fertilizer during your turf’s growing season.
Mow your lawn properly. If you mow your lawn often and take off only ⅓ of your turf’s crown whenever you mow, you’ll keep your lawn neat while preventing thatch buildup.
Practice grasscycling. Contrary to popular belief, leaving grass clippings on your lawn doesn’t actually contribute to thatch accumulation. Lawn clippings are some of the easiest plant materials to decompose. In fact, using lawn clippings as mulch promotes population growth of beneficial organisms that also get rid of thatch.
Maintain the proper soil pH for growing grass. The optimal soil pH for growing a healthy lawn and fostering microbial activity is around 6.0 to 7.0. You can check your soil pH level with a soil test; then, you can adjust the pH by adding lime to your lawn or adding sulfur, as needed.
Consider aerating your lawn. Lawn aeration helps your lawn breathe by reducing soil compaction. This promotes healthy grass growth and helps remove some thatch, too.
These tips can also help get rid of thatch. However, if you have a thick layer of thatch, good lawn care practices won’t be able to remove all of it.
