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). Conditions themselves are fine.

Tomorrow morning is your first decent window.

Next mow

Tomorrow 8am–2pm

Verdict: Good to go, 75% chance it holds

ground firm — 14mm rain over the last week, medium (loam) soil

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.

  1. Monday 19 October: no hours worth using. No — grass damp, wet underfoot, rain earlier that day.

Growth decides whether a cut is wanted, not how well it will go, so it is not one of the rows above and does not move the chances.Chance is the share of 94 forecast runs — the same weather models re-run from slightly different starting conditions — in which you could have mowed that hour.

Growth

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

34%Growing slowly

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

Growing slowly — roughly 1.2mm a day. It will not put on enough to need cutting within the next 10 days.

Held back by both temperature and short days — 10.4 hours of daylight at 14°C.

Over the next 10 days
about 7mm 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 Lowestoft, England

11.1°C52°F

at 6cm — germination depth

Seeding conditions are open — soil is 11.1°C at 6cm and holding above 9°C.

Cooling over the next 10 days.

Cross-checks against an independent estimate from air temperature (13.2°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

Lowestoft, England in detail

Soil temperature in Lowestoft, England is currently 11.1°C at 6cm, and falling about 0.8°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 11.1°C at 6cm and holding above 9°C.

4 of the next 10 days look workable. As for the weekend: nothing doing. Nothing to cut — the grass is barely growing (growth potential 0.08). Conditions themselves are fine.

The next recommended window in Lowestoft opens at 8am on Tuesday 20 October, because that is first light. Underfoot, the ground reads as firm after 11mm rain over the last week, medium (loam) soil.
