Mowing

When you can next cut it, and the best slot this weekend.

Best weekend slot

Sunday 4pm–5pm

Verdict: Good to go, 70% chance it holds

ground saturated — 64mm rain over the last week, medium (loam) soil

Next mow

Tomorrow 1pm–3pm

Verdict: Touch and go, 60% chance it holds

grass damp — wet underfoot, rain earlier that day

  • Worth watching: Ground still soft. 49mm rain over the last week, medium (loam) soil. A mower will mark it, and a ride-on will rut it. More

The next 10 days

Each row is a day, morning on the left. The more solid a block, the more of the forecast runs agree you can mow. Open a day for the hour-by-hour forecast behind it.

Growth

How fast it is growing, and when it will need cutting again.

28%Growing slowly

Of the fastest this grass could grow. The turf-industry measure, from today's temperature and day length.

Growing slowly — roughly 1.0mm a day. It will not put on enough to need cutting within the next 10 days.

Held back by both temperature and short days — 10.3 hours of daylight at 13°C.

Over the next 10 days

Next cut due
not within the next ten days

This only knows temperature and day length. Feeding, watering, shade and cutting height all move it, so treat it as a rough guide.

Worked out from the PACE Turf growth potential model and day length —how and why.

Seeding

Soil temperature at germination depth, and when the window opens.

Soil temperature in DN33, North East Lincolnshire

12.3°C54°F

at 6cm — germination depth

Soil is warming — it should cross 9°C in about 8 days, though the forecast doesn't run far enough to confirm it holds.

Cooling over the next 10 days.

Cross-checks against an independent estimate from air temperature (12.1°C), which agrees to within 0.7°C.

Almost every UK and Irish lawn is a ryegrass and fescue mix, whether it was sown or turfed. We assume that, and use 9°C as the seeding threshold.

Thresholds for every species

The differences are small. Ryegrass is the quickest off the mark; bluegrass is the slowest and wants the warmest soil. Everything else sits between.

Soil temperature at 6cm for reliable germination. Sources onthe method page.

Feeding

Why timing decides whether a feed does anything at all.

Coming in the app

Grass takes up nitrogen when it is growing. Feed a lawn that has stopped and most of it washes past the roots — which is why timing beats product choice.

Right now this lawn is not growing fast enough to make much use of a feed.

The app will work out the actual feeding windows for your lawn — along with weed control, scarifying and moss treatment — and tell you when they open without you having to check.

Why timing beats product choice

DN33, North East Lincolnshire in detail

Soil temperature in DN33, North East Lincolnshire is currently 12.3°C at 6cm, and falling about 2.2°C over the next 10 days. That depth matters because it is where grass seed sits and where roots start working, and it lags air temperature by days — which is why a warm afternoon here tells you very little on its own.

Lawns in this area are typically perennial ryegrass with fescue, which is what most lawns round here are sown with. That blend needs the soil to hold above 9°C before seed germinates reliably. Soil is warming — it should cross 9°C in about 8 days, though the forecast doesn't run far enough to confirm it holds.

None of the next 10 days are worth getting the mower out for. The other 10 are held back by wet grass or soft ground. The best weekend slot right now is Sunday 4pm–5pm, on the basis that ground saturated — 64mm rain over the last week, medium (loam) soil.

The next recommended window in DN33 opens at 1pm on Tuesday 20 October, because that is when the dew has burnt off — earlier than that and you are cutting wet grass. Underfoot, the ground reads as soft in places after 7mm rain over the last week, medium (loam) soil.
