Pocket Botanist
Check these first
- Feel the soil to see if it stays wet for days after watering.
- Check if water pools in low spots after rain.
- Dig up a small sample to see if the roots are firm or mushy.
Likely causes
Overwatering
PossibleHow to tell: The grass will look yellow or wilted even though the soil is wet. The roots may appear mushy or dark instead of firm and white.
What to do: Stop watering immediately and let the top inch of soil dry out. Aerate the lawn to improve oxygen flow to the root zone. Adjust your irrigation schedule to ensure you are only watering every 2 to 5 days.
Poor drainage
PossibleHow to tell: Water pools on the surface after rain or irrigation, and the grass feels spongy underfoot. The roots struggle to breathe in compacted or heavy clay soil.
What to do: Core aerate the lawn to break up compacted soil and improve water movement. If drainage is severe, consider installing a French drain or amending the soil with sand. Avoid walking on the lawn when it is saturated.

When to worry
Worry if you see large, sunken, or foul smelling patches that do not dry out. It is normal for grass to look slightly stressed after a heavy rainstorm.
Stopping it coming back
Ensure your lawn has a slight slope for runoff and avoid watering late in the evening. Proper aeration once a year keeps the soil structure healthy.

Questions people ask
- Can I save grass that has root rot?
- If the rot is caught early, improving drainage and reducing water can help the plant recover. If the roots are completely black and mushy, that section of grass may need to be replaced.
- How often should I check my soil moisture?
- Check the soil every few days, especially during hot or rainy weather. If the top inch is still damp, wait another day before watering.
