What customers say
Users are impressed with this lawn solution's ability to quickly achieve a vibrant green lawn, attributing its effectiveness to high nitrogen content. It also excels at rapidly eliminating common broadleaf weeds like dandelions and clover. Application is simple with standard spreaders, making the process user friendly. While results are professional grade, following application directions is crucial, especially during peak heat, to avoid lawn burn. Some find it less consistent on tougher weeds like crabgrass. Overall, customers agree this product provides excellent value for superior lawn color and effective weed control.
Know before you buy
The formula provides consistent nourishment for up to 16 weeks. Its 31% controlled-release nitrogen ensures your lawn receives a steady supply of nutrients over that four-month period.
This formula is designed to control over 250 types of broadleaf weeds, including common nuisances like dandelions. It is specifically formulated for broadleaf varieties, so it will not eliminate grassy weeds.
You can apply this granular formula during the spring, summer, or fall. For the best results, ensure the lawn is actively growing and the weeds are visible when you apply it.
Correct. The 0 in the middle of the NPK ratio indicates that this formula contains no phosphorus, which is often preferred for established lawns or regions with specific environmental restrictions on phosphorus runoff.
No, this product is intended for established lawns. Because it contains active weed-killing ingredients, it can inhibit the growth of new grass seeds and should only be used on mature turf.
The product is designed for easy application using a standard broadcast or drop spreader. To ensure even distribution across your 15,000-square-foot coverage area, walk at a steady pace and overlap your passes slightly.
