Killing mushrooms in grass can be tricky, as they are often a symptom of underlying soil conditions.
Identify the Mushroom
- Why? Knowing the type helps determine the best approach.
- How? Note color, shape, size, and location. Use a mushroom identification guide.
Improve Drainage
- Why? Mushrooms thrive in damp conditions.
- How? Aerate the lawn, reduce watering, and ensure proper drainage.
Adjust Soil pH
- Why? Some mushrooms prefer acidic or alkaline soil.
- How? Test your soil pH and amend accordingly with lime (to raise pH) or sulfur (to lower pH).
Use Fungicides (as a last resort)
- Why? Fungicides can kill mushrooms, but they don't address the underlying problem.
- How? Choose a fungicide labeled for lawn use and follow the instructions carefully.
Physical Removal
- Why? Removes the visible mushrooms.
- How? Hand-pick or mow over mushrooms regularly. Dispose of them properly.
Consider it a sign
- Why? Mushrooms are often beneficial, breaking down organic matter and improving soil health.
- How? Weigh the aesthetic concerns against the ecological benefits.
