This controlled-release fertilizer with a unique package of trace elements will get your lawn ready for the stresses of winter, and help it prepare to look healthy and beautiful in spring. The generous helping of potassium will make cell walls stronger and help grass regulate water more efficiently. Plus, plenty of magnesium will make its color sing. With a mixture of immediate release and slower controlled release of its nutrients, Sportsmaster® CRF Mini 13-5-20 will feed your turf both now and later, for 2 – 3 months, and its nitrogen will only be available to the plants when they need it, during the active growth season, conditioning it so it’s ready for colder weather. Apply from July to October. Just what you need to help turf resist temperature extremes and thrive once winter’s over.

  • Prepares turf for winter and helps it thrive when spring arrives
  • Stronger cell walls, improved water regulation and color
  • Controlled-release nitrogen, as well as immediate nutrition for your turf

Recommended Rate: 20 – 35 g/m²

Always trial on a small area before adjusting application rate or any other variables. As site conditions vary and application is outside ICL’s control, responsibility for results rests with the user.

Apply to dry foliage.

Watering-in after application will help with granule dispersion, give a quicker initial effect, and minimize footprint trails.

We recommend applying after aeration programs such as hollow tinning, slitting, and/or scarification to prevent granule damage. Do not apply during frosty or drought conditions.

  • Poly-S is a dual-coating controlled-release nitrogen technology available from ICL, combining sulfur and a biodegradable polymer. It ensures gradual nitrogen release over up to six months, unaffected by temperature or moisture fluctuations. This promotes steady turf growth, reduces mowing frequency, and minimizes nutrient leaching.
