0-0-25 (KTS) with 17% S – 1 qt

A strong lawn requires more than nitrogen alone. Potassium plays a key role in how grass regulates water, strengthens plant cells and moves nutrients throughout the plant. When potassium levels are low, lawns can struggle to perform efficiently, even when fertilization is consistent. What This Product Is This product is a KTS fertilizer (0-0-25) that supplies potassium and sulfur in a liquid, chloride-free form. It is designed to support lawn performance without adding nitrogen or phosphorus. What Five Star 0-0-25 Does This potassium lawn supplement helps improve nutrient efficiency by supporting nutrient movement within the plant and improving how grass uses nitrogen. Potassium strengthens plant cells and supports water regulation, while sulfur helps fertilizer work more effectively instead of pushing excessive growth. Application Rates Refer to the product label for full application instructions. When to Apply Five Star 0-0-25 Apply during periods of active growth or when lawns need additional performance support. This product is especially useful when lawns are under seasonal stress or when fertilizer efficiency needs improvement. Tools to Apply Five Star 0-0-25 Apply using a pump sprayer, hose-end sprayer or backpack sprayer for even coverage across grass areas. Five Star 0-0-25 is not a complete fertilizer and does not replace a full fertility program. Instead, it works alongside your existing plan to help nutrients move more efficiently and support stronger roots. Your main fertility plan should still focus on nitrogen, phosphorus and potassium, such as a Lawnifi® lawn care program, with additional nutrients applied only when a soil test shows a specific need. This is not a quick green-up product. It’s a performance tool designed to help lawns stay strong, recover faster and make better use of the nutrients you already apply. When Your Lawn Struggles Under Stress If your lawn wilts in heat, recovers slowly from traffic or struggles during dry periods despite regular fertilization, potassium may be limiting performance. Five Star 0-0-25 supplies potassium and sulfur to strengthen grass from the inside, supporting water regulation and nutrient movement without forcing excess growth. The added sulfur helps your lawn use nitrogen more efficiently, so fertilizer works harder. The result is a lawn that handles stress better, recovers faster and performs more consistently throughout the growing season. Downloads Product Label
