Interpretation
What this means for your grass.
- Bermuda
- Bermuda's growth is slowing toward dormancy. Stop pushing nitrogen. Soil is already below the 70°F annual bluegrass germination point, so fall pre-emergent is late, but it still blocks the seed that germinates over the next couple of months.
- Zoysia
- Zoysia is slowing toward dormancy. Stop nitrogen. Soil is below the 70°F annual bluegrass germination point, so fall pre-emergent is late but still worth putting down for later-germinating seed.
- St. Augustine
- St. Augustine is slowing toward winter. Hold nitrogen. Winter weeds are already up, so treat what you can see rather than applying a pre-emergent now.
- Cool-season
- The best growing range of the year for cool-season grass. This is prime time to fertilize and to overseed. If you are overseeding, do not apply pre-emergent: it stops grass seed the same way it stops weed seed.
