Turf Disease Alert

With the unseasonably high rainfall during the last few weeks, fungus on lawns will be on the rise. Fungus can thrive on lawns when warm temperatures and high moisture are present. Here are a few ways you can help prevent fungus from attacking your yard.

  1. Only water your lawn as much as necessary. The average yard only needs about 1 inch of water once a week during the warmest part of the season to stay healthy. Most fungi thrive in moist conditions.

  2. Avoid spreading it. Dollar spot and several other fungal diseases spread with minimal effort. Avoid walking in fungus infected turf, avoid mowing wet turf and clean your yard tools including mower deck and blade with a bleach and water solution after they are used in infected areas.

  3. Fertilize your lawn. Grass that does not receive enough nitrogen and potassium can become weak, which makes it easier to catch a fungal disease and harder to fight off. Fertilizer does for sick lawns what vitamin C does for humans during a cold. A good dose of slow-release fertilizer can give your grass what it needs to begin its recovery from various fungi.

  4. Keep your lawn mowed at a healthy height. Lawns that are cut too short can be stressed, making them weak. Lawns that are cut too high can be a breeding ground for fungi and insects.

  5. De-thatch your lawn. Soil that lacks proper air circulation is more likely to get a fungal disease, so de-thatching is often used as a preventative treatment.

  6. Apply a fungicide. Pillar G can be applied to any lawn as a preventative and a curative for most fungus. A bag of Pillar G will cover 10,000 square feet of lawn. Pillar G Granular Fungicide Label
