How you feel about mowing

Sensible middle ground.

Petrol or battery. The baseline.

Growth

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

10%Barely growing

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

The lawn is barely growing, so it does not need cutting. Leave it — taking leaf off a sward that cannot replace it costs more than it gives.

Held back by both temperature and short days — 10.5 hours of daylight at 9°C.

Over the next 10 days
about 6mm of leaf
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 PL6, Plymouth

12.0°C54°F

at 6cm — germination depth

Seeding conditions are open — soil is 12.0°C at 6cm and holding above 9°C.

Warming over the next 10 days.

Cross-checks against an independent estimate from air temperature (10.2°C), which agrees to within 0.2°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

PL6, Plymouth in detail

Soil temperature in PL6, Plymouth is currently 12.0°C at 6cm, and rising about 2.0°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. Seeding conditions are open — soil is 12.0°C at 6cm and holding above 9°C.

3 of the next 10 days look workable. The other 7 are held back by wet grass or soft ground. As for the weekend: nothing doing. ground waterlogged.

The next recommended window in PL6 opens at 2pm on Monday 19 October, and holds while conditions stay put. Underfoot, the ground reads as firm after 11mm rain over the last week, medium (loam) soil.
