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 Feb 12 and 55°F from Mar 1. |
| 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 (66°F soil today). |
| Seed warm-season grass | Bermuda, zoysia and centipede need soil of 65°F or more | Warm enough 66°F: at or over 65°F. |
| Plant out tomatoes | Tomato roots want soil of 60°F or more (check your frost date as well) | Soil warm enough 66°F: at or over 60°F. Plant only after your last frost. |
| Sow peas, lettuce and spinach | Cool-weather crops germinate once soil reaches about 40°F | Warm enough 66°F: at or over 40°F. |

Growing degree days in Columbia
Base 50°F, from 1 January to Nov 7, at the Columbia station (9.6 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.

- About 66°F on average in the top 4 inches (0–10 cm), with a low of 61°F and a high of 70°F, from NOAA's GFS model run of Nov 11, 12:00 UTC (7 am Eastern).
- Is it time to put down crabgrass preventer in Columbia?
- The spring window is closed. It opens again when the soil holds 50°F. Last spring the soil held 50°F from Feb 12 and 55°F from Mar 1.
- When did the soil in Columbia reach 55°F this year?
- The 5-day average held 55°F from Mar 1, 2026.
- How accurate is a modelled soil temperature?
- Against NOAA's 108 reference stations the model's daily average was off by 4.2°F on average, and within 5°F on 68% of days. A shaded, mulched or watered yard can differ more.
