Mowing

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

Best weekend slot

Nothing doing

Verdict: Not worth it

Nothing to cut — the grass is barely growing (growth potential 0.08). And nothing else in the next 10 days either.

Next mow

Nothing above 65% this week

Verdict: Not worth it

Nothing to cut — the grass is barely growing (growth potential 0.10). Conditions themselves are fine.

Best chance is Thursday at 35%.

  • Worth watching: Ground still soft. 22mm 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.

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 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 BA4, Somerset

9.3°C49°F

at 6cm — germination depth

Soil is warming — it should cross 9°C in about 7 days, though the forecast doesn't run far enough to confirm it holds.

Warming over the next 10 days.

Cross-checks against an independent estimate from air temperature (9.7°C), which agrees to within 0.3°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

BA4, Somerset in detail

Soil temperature in BA4, Somerset is currently 9.3°C at 6cm, and rising about 1.7°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 7 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. As for the weekend: nothing doing. Nothing to cut — the grass is barely growing (growth potential 0.08). And nothing else in the next 10 days either.

Nothing in the current forecast for BA4 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.
