Growth
How fast it is growing, and when it will need cutting again.
0.97Growing 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 5.8mm a day. A lawn cut today would be ready for another in around 3 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 18.9°C at 6cm and holding above 12.5°C.
Warning: Heat stress
Thursday 3 September gets hot enough to stress the sward. Mow early or late, and raise the height.
Seeding
Soil temperature at germination depth, and when the window opens.
Soil temperature
66°F18.9°C
at 6cm — germination depth
Cooling over the next 10 days.
Seeding conditions are open — soil is 18.9°C at 6cm and holding above 12.5°C.
Cross-checks against an independent estimate from air temperature (19.2°C), which agrees to within 0.5°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 use12.5°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 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.
Schenectady, New York in detail
Soil temperature at 6cm in Schenectady, New York is currently 18.9°C, and falling about 18.7°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 18.9°C at 6cm and holding above 12.5°C.
7 of the next 10 days are good mowing days. The best weekend slot right now is Saturday 8am–5pm, on the basis that rain earlier today, ground firm.
The next recommended window in Schenectady opens at 2pm on Thursday 3 September, 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 34mm rain over the last week.
