How can you tell the difference between Melt Out Fungus and Dry Spots?
As it continues to warm up, you might have some dry spots in your lawn. But the bad news is that those conditions, as well as weather changes, drought stress, and mowing too short, are also the ideal conditions for the lawn fungus Melt Out to develop. We are seeing A LOT of melt out right now. And while the two issues can look similar, you need to treat them very differently! While dry spots need more water, overwatering Melt Out fungus will actually make the fungus worse!
So how to tell the difference?
Melt Out appears as yellow/straw-colored patches and can become active along mow lines (as pictured in the upper images). When Melt Out is active along mow lines, it is pretty easy to diagnose. But since it can also appear as large patches, you can tell the difference between dry spots and Melt Out by feeling the grass. The grass in dry spots will be dry and brittle to the touch, but grass affected by Melt Out will feel similar to the green grass around it. And while dry spots may be a similar color to that yellow hue of Melt Out, they also may be white or grayish depending on the type of grass (as in the lower image).
So what to do if you have dry spots? Well, increase watering in the affected areas!
But what can you do if you have Melt Out?
-Many people assume Melt Out spots are dry spots and begin overwatering them. DON'T! This will actually make the fungus worse. Let the yellow spots dry out for 2 days, then return to watering as normal.
- Increase your mow height to 3 inches and make sure your mower blade is sharp. You should also bag and discard your mow clippings until the Melt Out is no longer present in your lawn. Leaving clippings on your lawn while the fungus is still present will allow it to continue to spread.
-After making these adjustments, if you are still seeing Melt Out, we can apply a granular fertilizer to the affected areas during your next lawn application to help clear up the fungus.
