How to Prevent Lawn Diseases

Learn how to prevent lawn diseases from landscape architect Patrick Weisel in this Howcast video.


In this video, we're going to talk about how to prevent lawn diseases. The first thing you want to do is make sure you're mowing with a sharp blade, because a dull blade will tear the grass blade and leave a ragged edge which invites diseases and pestilence into the grass plant. Next, you'll want to make sure to mow only when your lawn is dry. Never mow a wet lawn, because that allows the fungi and different kinds of diseases to spread around throughout the turf. The other thing you want to concern yourself with avoiding lawn diseases is water. Never overwater your lawn because that invites all kinds of fungal infections into the lawn, and when you do water, remember to water in the morning. That gives the grass plenty of time to take up the water and, also, plenty of time for the sun to dry the grass out so it doesn't go into the evening hours or the night wet and promote fungal growth. So those are my tips for avoiding diseases in your lawn.
