What It's For
A low-analysis granule usually sold as the carrier for a pre-emergent such as prodiamine or dithiopyr. You buy it for the herbicide, not the potassium.
When to Use It
Whenever its active ingredient is due: early spring for crabgrass prevention, late summer/fall for poa annua.
Before You Spread It
- Apply it at the rate on the label for the herbicide, not for its potassium.
- Pre-emergents stop grass seed from germinating too. Keep them off areas you plan to seed.
