Chance is the share of 82 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.
44%Growing steadily
Of the fastest this grass could grow. The turf-industry measure, from today's temperature and day length.
Roughly 2mm a day. A lawn cut today would be ready for another in about a week.
Held back by both temperature and short days — 11.1 hours of daylight at 14°C.
- Over the next 10 days
- about 17mm of leaf
- Next cut due
- in about a week
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 Wichita, Kansas
57°F13.9°C
at 6cm — germination depth
Seeding conditions are open — soil is 13.9°C at 6cm and holding above 12.5°C.
Cooling over the next 10 days.
An independent estimate from air temperature gives 12.9°C — 3.3°C away. The two models disagree, so treat this figure with caution.
Most cool-season lawns in the northern US and Canada are bluegrass, tall fescue, or a mix of the two. We assume that, and use 12.5°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 ryegrass | 8°C | 5–10 |
| Red / chewings fescue | 8–10°C | 10–14 |
| Tall fescuelikely yours | 10–12°C | 10–14 |
| Browntop bentColonial bentgrass | 10–12°C | 14–21 |
| Smooth-stalked meadow grassKentucky bluegrasslikely yours | 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.
Wichita, Kansas in detail
Soil temperature in Wichita, Kansas is currently 13.9°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 Kentucky bluegrass with tall fescue, the usual mix for cool-season lawns at this latitude. That blend needs the soil to hold above 12.5°C before seed germinates reliably. Seeding conditions are open — soil is 13.9°C at 6cm and holding above 12.5°C.
8 of the next 10 days are good mowing days. The best weekend slot right now is Saturday 8am–7pm, on the basis that dry for over a week by then, ground firm.
The next recommended window in Wichita opens at 6pm on Tuesday 20 October, because anything earlier is the hour your neighbours will remember. Underfoot, the ground reads as soft after 80mm rain over the last week, medium (loam) soil.
