Lawn mowing advice
Clear answers about rain, timing, seasons, and healthy grass cutting, written for both UK and US lawns.
Weather
Can I mow wet grass?Usually no. Wait until the grass blades and soft ground have dried enough for a clean, safe cut.Should I mow before rain?Mow before rain only when the lawn is dry now and you have enough time to finish safely before the weather changes.Can I mow grass after rain?Yes, once the blades are dry, the ground is firm, and the mower can pass without rutting or clumping.When can I mow after heavy rain?Wait until both the grass and the ground have recovered. After heavy rain, the soil often stays too soft long after the surface starts to look drier.
Timing
When should I mow my lawn?Mow when the grass is actively growing, dry enough to cut cleanly, and no major heat, rain, or wind hazard is expected.Best time of day to mow the lawnLate morning or late afternoon is often best, after dew has dried and outside the hottest part of the day.When should I do the first mow of the year?Wait until the lawn is actively growing, dry enough to support the mower, and tall enough to justify a light first cut.
Routine
How often should I mow my lawn?Mow often enough to remove no more than roughly one-third of the blade height at a time.How do cutting height and the one-third rule work in practice?Aim to remove no more than about one-third of the blade in a single mow, and raise the deck when the lawn is stressed, overgrown, or drying out quickly.Should I mow during drought or heat stress?Usually mow less often and less aggressively. A lawn under drought or heat stress is easier to damage and slower to recover.
Seasonal
Should I mow in spring?Yes, once growth has resumed and the ground is firm enough. Start high and mow only when conditions are dry.Should I mow in summer?Usually yes, but mow less aggressively during heat or drought and avoid the hottest part of the day.Should I mow in autumn?Yes, while grass is still growing and conditions are dry enough. Gradually reduce frequency as growth slows.Should I mow in winter?Usually wait. Mow only during mild, dry spells when grass is clearly growing and the ground is firm.
