Soil temperature
20.6°C69°F
at 6cm — germination depth
Cooling over the next 11 days.
Seeding conditions are open — soil is 20.6°C at 6cm and holding above 12.5°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 |
What this means right now
Good: Seeding window open
Seeding conditions are open — soil is 20.6°C at 6cm and holding above 12.5°C.
Warning: Heat stress
Wednesday 2 September gets hot enough to stress the sward. Mow early or late, and raise the height.
Worth watching: Ground still soft
63mm rain over the last week. A mower will mark it, and a ride-on will rut it.
