Growth
How fast it is growing, and when it will need cutting again.
0.87Growing strongly
Growth potential, 0 to 1 — the turf-industry measure of how fast grass can grow at today's temperature and day length.
Putting on about 5.2mm a day. A lawn cut today would be ready for another in around 4 days.
Worked out from the PACE Turf growth potential model and day length —how and why.
What this means right now
Good: Seeding window open
Seeding conditions are open — soil is 16.4°C at 6cm and holding above 9°C.
Seeding
Soil temperature at germination depth, and when the window opens.

at 6cm — germination depth
Cooling over the next 10 days.
Seeding conditions are open — soil is 16.4°C at 6cm and holding above 9°C.
Cross-checks against an independent estimate from air temperature (16.5°C), which agrees to within 0.5°C.
Almost every UK and Irish lawn is a ryegrass and fescue mix, whether it was sown or turfed. We assume that, and use9°C as the seeding threshold.
I know what grass I have
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 temp | Days |
|---|---|---|
| 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 growing well enough to use 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.
Harrogate, England in detail
Soil temperature at 6cm in Harrogate, England is currently 16.4°C, and falling about 4.5°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 16.4°C at 6cm and holding above 9°C.
9 of the next 10 days are good mowing days. The other one is held back by wet grass or soft ground. The best weekend slot right now is Sunday 10am–8pm, on the basis that no rain since Friday, ground firm.
The next recommended window in Harrogate opens at 10am on Thursday 3 September, because the rain clears by then. Underfoot, the ground reads as firm after 25mm rain over the last week.
