What the soil says for each job
Today's verdicts use the 5-day mean of the modelled 0–4 in layer.
| Job | Soil rule | Today |
|---|---|---|
| Crabgrass pre-emergent | Apply while the soil holds 50 to 55°F, before crabgrass germinates at about 55°F | Season over The spring window is closed. It opens again when the soil holds 50°F. Last spring the soil held 50°F from May 12 and 55°F from May 25. |
| Seed or overseed cool-season grass | Fescue, bluegrass and ryegrass germinate best in soil of 50 to 65°F | Too late in the season Past the usual Aug 15 to Oct 15 seeding window (47°F soil today). |
| Seed warm-season grass | Bermuda, zoysia and centipede need soil of 65°F or more | Too cold 47°F: under 65°F. |
| Plant out tomatoes | Tomato roots want soil of 60°F or more (check your frost date as well) | Too cold 47°F: under 60°F. |
| Sow peas, lettuce and spinach | Cool-weather crops germinate once soil reaches about 40°F | Warm enough 47°F: at or over 40°F. |

Growing degree days in Andover
Base 50°F, from 1 January to Nov 7, at the New Hope station (25.8 km).
A growing degree day is each degree that the day's average temperature runs above 50°F. Insects, weeds and crops develop by accumulated GDD, so the number says how far the season has run. Every city.
