Tips for Getting Rid of Brown Patches on Lawn
The unsightly brown patches on lawn that cause so much distress to lawn owners are caused by the proliferation of a fungus called Rhizoctonia. Like any fungus, this species also grows and spreads in cool and moist environments, that’s why the brown patches that indicate its presence usually appear in early fall. Fortunately, the fungus is not very hardy, so here are some efficient methods for combatting it:
- Water exactly on schedule – ideally, you should water your lawn every 3-4 days during hot periods and increase the intervals when the air starts to cool at the end of summer. Always water early in the morning to allow your grass to dry before the dew drops appear in the evening;
- Leave the grass longer – cropping the grass very short to get rid of the diseased leaves might be tempting, but it is a mistake. Set the mowing blades about half an inch higher than usual and make sure that the blades are clean and sharp;
- Remove thatch – a thick layer of thatch prevents the proper ventilation of the soil surface and promotes the proliferation of the fungus, so you need to remove it to maintain the cleanliness of your lawn.
