Growth
How fast it is growing, and when it will need cutting again.
46%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 day length, not temperature — 11.0 hours of daylight. Warm weather will not change that much.
- Over the next 10 days
- about 18mm 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 Evansville, Indiana
56°F13.5°C
at 6cm — germination depth
Seeding conditions are open — soil is 13.5°C at 6cm and holding above 12.5°C.
Warming over the next 10 days.
Cross-checks against an independent estimate from air temperature (13.9°C), which agrees to within 1.2°C.
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.
Evansville, Indiana in detail
Soil temperature in Evansville, Indiana is currently 13.5°C at 6cm, and rising 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 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 13.5°C at 6cm and holding above 12.5°C.
9 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 Evansville opens at midday on Tuesday 20 October, and holds while conditions stay put. Underfoot, the ground reads as firm after 24mm rain over the last week, medium (loam) soil.
There is frost in the forecast for Evansville, Indiana: Thursday 29 October has hours cold enough to freeze the leaf. Stay off the grass until it lifts — mowing frosted turf ruptures the cells and the damage shows for weeks.
