Growth
How fast it is growing, and when it will need cutting again.
11%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 10°C.
- Over the next 10 days
- about 6mm 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 TQ13, South Hams
12.0°C54°F
at 6cm — germination depth
Seeding conditions are open — soil is 12.0°C at 6cm and holding above 9°C.
Warming over the next 10 days.
Cross-checks against an independent estimate from air temperature (10.2°C), which agrees to within 0.2°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.
TQ13, South Hams in detail
Soil temperature in TQ13, South Hams is currently 12.0°C at 6cm, and rising about 2.0°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 12.0°C at 6cm and holding above 9°C.
4 of the next 10 days look workable. The other 6 are held back by wet grass or soft ground. As for the weekend: nothing doing. ground waterlogged.
The next recommended window in TQ13 opens at 4pm on Monday 19 October, and holds while conditions stay put. Underfoot, the ground reads as firm after 4mm rain over the last week, medium (loam) soil.
