Questions
- What is the soil temperature in ZIP code 85321 today?
- About 69°F on average in the top 4 inches (0–10 cm), low 63°F and high 77°F, from NOAA's GFS model run of Nov 11, 12:00 UTC (7 am Eastern). It is a model value for a grid cell 14.8 km from the ZIP centre, not a reading from your yard.
- Is it time for crabgrass preventer in 85321?
- Soil here stayed above 50°F all last winter, so the 50 to 55°F soil rule gives no spring window. Time pre-emergent to your local calendar.
