As autumn deepens, many homeowners are wondering when to stop mowing their lawns now that sunny days have given way to rainfall and falling leaves. A gardening expert has revealed the ideal timing for the final grass cut of the season, helping your turf survive winter and thrive in spring.
Temperature Threshold Determines Last Cut
Craig Wilson, in-house gardening expert at Gardeners Dream, says a specific temperature threshold should be considered before taking out the mower. He recommends finishing lawn maintenance before temperatures drop to seven degrees or lower, as this is when grass growth slows significantly. The lawn remains relatively dormant through winter before resuming normal growth in March.
Wilson suggests scheduling the final mow from late October through to the end of November. However, given increasingly mild conditions, this last cut can potentially be delayed slightly if necessary.
Regional Deadlines Vary Across UK
Current forecasts for England, Wales and Northern Ireland indicate temperatures won't fall to seven degrees or below until December 8. Meanwhile, Scottish residents face an earlier deadline of December 4. This still provides locations throughout the UK ample opportunity to complete that crucial final trim, with only a few days' variation between regions.
Wilson stated: "Ultimately, my advice would always be to keep an eye on the weather as we head into November. You want to make sure your lawn is cut before the first frost hits; otherwise, you risk the chance of damaging your grass."
Cut Length and Aftercare Tips
Wilson added: "Therefore, to be on the safe side, I would always cut my lawn just before the end of November, even if it's been a mild autumn, just in case the weather decides to change and temperatures drop quicker than previously predicted."
Mammotion also proposes October through early November as the optimal period to mow lawns, ahead of the initial frost, while maintaining the length marginally longer. Their website claims the objective for the ultimate cut is "protection", and the autumn trim ought to be longer at approximately four to five cm. This provides insulation for the soil and enhanced protection to the "delicate crowns of the grass".
Wilson proposes that after the final trim, aerating the lawn prevents waterlogging and compaction through winter. This can be done by puncturing the lawn with a garden fork to improve drainage.
