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 0.06). Conditions themselves are fine.
Wednesday afternoon is your first decent window.
Next mow
Wednesday 2pm–5pm
Verdict: Good to go

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.
Monday 19 October: no hours worth using. No — grass wet, still wet underfoot, rain 3 hours ago.

Growth
How fast it is growing, and when it will need cutting again.
22%Growing slowly
Of the fastest this grass could grow. The turf-industry measure, from today's temperature and day length.
Growing slowly — roughly 0.8mm 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 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 PE35, King's Lynn and West Norfolk
13.8°C57°F
at 6cm — germination depth
Soil is warming — it should cross 9°C in about 8 days, though the forecast doesn't run far enough to confirm it holds.
Cooling over the next 10 days.
Cross-checks against an independent estimate from air temperature (11.8°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.
PE35, King's Lynn and West Norfolk in detail
Soil temperature in PE35, King's Lynn and West Norfolk is currently 13.8°C at 6cm, and falling about 0.7°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 8 days, though the forecast doesn't run far enough to confirm it holds.
2 of the next 10 days look workable. As for the weekend: nothing doing. Nothing to cut — the grass is barely growing (growth potential 0.06). Conditions themselves are fine.
The next recommended window in PE35 opens at 2pm on Wednesday 21 October, because that is when the dew has burnt off — earlier than that and you are cutting wet grass. Underfoot, the ground reads as firm after 14mm rain over the last week, coarse (sandy) soil.
