Questions

What is the soil temperature in ZIP code 33404 today?
About 80°F on average in the top 4 inches (0–10 cm), low 76°F and high 85°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 7.2 km from the ZIP centre, not a reading from your yard.
Is it time for crabgrass preventer in 33404?
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.
