Lawn care, with the weather data behind it.
When to stop mowing for winter in the UK
There's no single last-mow date for the UK. Growth winds down as the soil cools and the days shorten, and neither happens on the same date in Aberdeen as in Brighton.
When to scarify a UK lawn (and when not to)
Scarifying tears out thatch and moss, and the lawn needs strong growth to recover. That makes early autumn the main window, and a drought the worst possible time.
When to overseed a UK lawn for the best germination odds
Early autumn gives grass seed warm soil, regular rain and less competition from weeds. Spring works too, once the soil has properly warmed. Timing matters more than the seed.
When should you feed your lawn in the UK?
Not 'early spring' — a specific soil temperature, sustained for a specific number of days. Here's the real rule, and why it isn't the same as the moss-and-weed window.
How much rain is 'enough'? Inside the soil moisture deficit model
'It hasn't rained in a while' isn't a threshold. 60mm of accumulated deficit is — and a real 2026 case where one alert wasn't enough is why watering alerts now escalate.
When should you mow your lawn in the UK?
Generic advice says 'weekly from March.' UK weather data says something more specific — and it changes every year.
The science behind Turf Alert
86 years of UK weather data, checked against independent records — including reconstructing four of the UK's five worst droughts without being told to.
No Mow May: is it worth it?
The case for putting the mower away for a month — and what it does to your lawn's growth in the meantime.
