Interpretation
What this means for your grass.
- Bermuda
- Bermuda is dormant for the winter. No fertilizer, no PGR. Winter weeds are already up by now, so treat what you can actually see rather than applying a pre-emergent.
- Zoysia
- Zoysia is dormant or nearly so. Hold all fertilizer and PGR. Winter weeds have already germinated, so treat what is visible instead of applying a pre-emergent.
- 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.
