Getting Rid Of Mold In The Yard

With different molds, different actions also needed to be taken. See the following to know more:


  • Brown patches

Brown patches appear as a large spot of dried grass caused by the fungus Rhizoctonia.

To avoid this, fertilize carefully, improve air circulation in soil, and water the yard properly. If it’s already existing, a fungicide with fludioxonil is what you need.

If it’s necessary to use chemicals, it’s best to ask a professional’s help.


  • Pink snow mold

Pink snow mold often occurs during late winter, when a layer of snow seals moisture underneath, destroying grass from the crown to the roots. This mold becomes visible as the snow melts and would appear like circular patches with a hint of white to pink color.

Don’t let the snow cover the lawn for too long and remove it to get rid of mold. Increase the air circulation by removing excess thatch.

Pink snow molds love high nitrogen levels, so it’s best to avoid fertilizer with high levels of nitrogen.


  • Gray snow mold

Gray snow mold appears in irregular patches of white to gray fluffy fungal growth. A hefty snow stockpile on the unfrozen ground provides an ideal condition for this disease.

It’s best to frequently mow your lawn and not use too much nitrogen fertilizers going into winter to prevent this mold. As for the removal, rake the affected area and mow the lawn and let it dry as thoroughly as you can.

To get rid of this, fertilizing during late spring and early summer will help. If it has become a chronic problem, then it’s best to have a fungicide treatment.


  • Powdery mildew

Powdery mildew can be easily inferred as it appears as light grey or fine white spots, and it can spread and cover an entire stalk. It requires high humidity and warm temperatures to grow.

To get rid of this, use sulfur-containing organic fungicides as a treatment and preventive agent.


  • Dollar spot

Dollar spot resembles hollow patches of straw-colored grass. Once left untreated, it can rapidly spread.

The best way to treat this is to use fungicides such as Propiconazole & Fludioxonil.


  • Slime mold

This mold somehow resembles foam and is frequently spotted as orange or yellow. It does look unsightly, but it doesn’t bring any harm to its surroundings.

There’s no urgent demand for slime mold removal, but you can rake up this mold and let it dry out if you want. Learn from this article about how to get rid of slime mold on mulch.


Mold Prevention For Your Lawn

Unlike the preparations done indoors to deter mold from growing, managing the moisture and humidity outdoors is tougher. However, this doesn’t mean that there’s no other way to avoid mold growth.

The following advice can help in lessening the likelihood of growth in your yard:

  1. Avoid watering at night. It’s most suitable to water in the morning so that the moisture wouldn’t last long enough to draw fungi. 
  2. Don’t exaggerate watering; if it rained, then there’s no need to water your lawn. Read this article to know about the best time to water your lawn.
  3. Don’t use too much or too little fertilizer. 
  4. It’s best to monitor the thatch in your yard or lawn because too much thatch can prevent the air from flowing, consumption of water, and fertilizers from reaching the roots.
  5. Mow regularly but do not cut too short because short grass attracts more diseases.
  6. Testing the soil is also helpful. Make sure to balance the nutrients of the ground. 
  7. Apply fungicide as a preventative treatment.
