Q: Is 31% nitrogen too high for residential lawns?

A: Not when combined with 100% SurfCote slow release. All nitrogen is polymer-encapsulated, releasing slowly over up to 4 months — dramatically reducing burn risk.

Q: Why choose this over the 13-0-5 or 20-0-4 Barricade options?

A: Shaw's 31-0-4 is the premium option for properties needing the most aggressive feeding alongside season-long weed prevention. The 100% SurfCote coating provides the longest, most consistent feeding window.

Q: How long does the nitrogen last?

A: With 100% SurfCote polymer coating, nitrogen releases gradually for up to 4 months, depending on soil moisture and temperature.

Q: Is this safe for established warm and cool-season grasses?

A: Yes — Shaw's 31-0-4 is suitable for established turfgrasses. Always refer to the product label for specific grass type recommendations.

Q: Where do I find application rates and timing?

A: On the manufacturer's product label. Current label links are being added to this page. Until then, stop by any Champion location or contact us and our team will get you the label information you need.

Q: Is a Safety Data Sheet (SDS) available?

A: Yes. The SDS for this product is on file and available on this page and at the counter, including for contractor accounts.

Q: What does 100% SurfCote mean?

A: SurfCote is Knox's polymer-coated, controlled-release nitrogen. The percentage tells you how much of the bag's nitrogen is coated for gradual release.

Q: Can homeowners buy this product?

A: Yes. Shaw's products are sold to both homeowners and professionals at all four Champion locations. Always read and follow label directions.
