good to go touch and go dark, frost or snow already goneFainter means fewer forecast runs agree.
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. The rows under it in each day's table are what those runs expect on average, which is why an hour can look reasonable line by line and still fall short: the chance only counts runs where everything came together at once. Hover any cell for what the runs that ruled it out hit.
Growth
How fast it is growing, and when it will need cutting again.
26%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 — 10.4 hours of daylight at 12°C.
- Over the next 10 days
- about 9mm 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 CT9, Thanet
12.8°C55°F
at 6cm — germination depth
Seeding conditions are open — soil is 12.8°C at 6cm and holding above 9°C.
Cooling over the next 10 days.
Cross-checks against an independent estimate from air temperature (12.3°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.
| Species | Soil needed | Days to sprout |
|---|---|---|
| Perennial ryegrasslikely yours | 8°C | 5–10 |
| Red / chewings fescuelikely yours | 8–10°C | 10–14 |
| Tall fescue | 10–12°C | 10–14 |
| Browntop bentColonial bentgrass | 10–12°C | 14–21 |
| Smooth-stalked meadow grassKentucky bluegrass | 12–13°C | 14–28 |
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.
CT9, Thanet in detail
Soil temperature in CT9, Thanet is currently 12.8°C at 6cm, and falling about 1.1°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 12.8°C at 6cm and holding above 9°C.
7 of the next 10 days are good mowing days. The other 3 are held back by wet grass or soft ground. The best weekend slot right now is Saturday 8am–2pm, on the basis that grass dry — rain earlier that day.
The next recommended window in CT9 opens at midday on Wednesday 21 October, because the rain clears by then. Underfoot, the ground reads as firm after 16mm rain over the last week, coarse (sandy) soil.
