Likely causes
Nitrogen deficiency
Most likelyHow to tell: The grass blades lose their deep green color and appear pale or yellowish across the entire lawn.
What to do: Apply a nitrogen rich fertilizer at a rate of 0.5 to 1 pound of nitrogen per 1000 square feet. Water the area thoroughly after application to help the nutrients reach the roots.
Poor drainage
PossibleHow to tell: Yellowing occurs in low spots where water pools for long periods after rain or irrigation.
What to do: Improve soil aeration by core aerating the lawn to allow water to drain away from the surface. Avoid overwatering in these specific low areas.

When to worry
Worry if the yellowing spreads rapidly across the lawn or if the grass begins to die back. Minor yellowing after a heavy rain is usually temporary.
Stopping it coming back
Maintain a consistent fertilization schedule and ensure your lawn has proper grading to prevent water accumulation.

Questions people ask
- Can overwatering cause yellowing?
- Yes, keeping the soil too wet for too long can suffocate the roots and lead to yellowing. Ensure the soil is damp but not waterlogged.
- Should I mow while the grass is yellow?
- It is best to wait until the grass recovers. Mowing stressed grass can make the situation worse.
