Wait 24-48 hours after rain before mowing to allow grass to dry completely.
Mowing wet grass can damage your lawn and mower. Wet grass clippings clump together, clog mower decks, and create an uneven cut. The soil also becomes compacted when walked on while wet, potentially damaging grass roots. For best results, check that grass blades are dry to the touch and soil is firm before mowing after rainfall.
Factors Affecting Drying Time
- Temperature: Warmer weather speeds up drying
- Sunlight: Direct sun exposure reduces moisture faster
- Grass length: Taller grass retains more water
- Soil type: Clay soils drain slower than sandy soils
- Rainfall amount: Heavy rain requires longer drying time
Testing If Grass Is Ready to Mow
- Walk across the lawn - if shoes stay dry, it's likely ready
- Check grass blades - they should feel dry, not cool and damp
- Pull up a grass blade - if no water droplets appear, it's dry
- Observe soil - it should be firm, not squishy or leaving footprints
Wet vs Dry Mowing Comparison
| Condition | Mowing Result | Mower Impact | Lawn Health |
|---|---|---|---|
| Wet Grass | Uneven cut, clumping | Clogged deck, rust risk | Soil compaction, disease risk |
| Dry Grass | Clean, even cut | Optimal performance | Healthy growth, no damage |
