By the end of February, our temperatures will start to warm up providing the perfect time to fertilize your lawn to get it off to a healthy start for the season. All fertilizers will have an NPK which is Nitrogen, Phosphorous, and Potassium. Nitrogen is essential for plant growth and to make your grass greener. Phosphorous is essential for root development, and Potassium is essential for the overall health of the plant and its metabolism. For the spring fertilization on an existing lawn, you will want to choose a fertilizer that has a higher Nitrogen number. For spring fertilization on newer lawns, you will want a more balanced fertilizer to encourage root growth and the overall health of the turf. Fertilizers can be quick-release or slow-release. Slow release is preferred over quick release for turfgrass applications. There are many different fertilizer manufacturers out there, so choose the NPK that is best for your lawn and always follow the manufacturer’s directions to ensure the best results.
