Best weekend slot

Nothing doing

Verdict: Not worth it

Next mow

Nothing above 65% this week

Verdict: Not worth it

0.1mm of rain falling.

Best chance is Saturday at 45%.

The next 10 days

Growth

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

25%Growing slowly

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

Growing slowly — roughly 0.9mm 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 12°C.

Over the next 10 days
about 5mm 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 Doncaster, England

10.9°C52°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 (11.5°C), which agrees to within 0.1°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

Doncaster, England in detail

Soil temperature in Doncaster, England is currently 10.9°C at 6cm, and falling about 1.2°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.

2 of the next 10 days look workable. The other 8 are held back by wet grass or soft ground. As for the weekend: nothing doing. conditions never quite get there. And nothing else in the next 10 days either.

Nothing in the current forecast for Doncaster opens a sensible window. The ground reads as firm after 7mm rain over the last week, medium (loam) soil, and that is usually what decides it at this time of year.
