Fertilizers and pesticides can help produce a lush lawn, but they must be used according to instructions to prevent water quality problems. Compost mixed with your soil can provide some of the organic matter and nutrients your soil needs without using commercial preparations.
Test Your Soil First! Only fertilize based on your soil needs.Retest soil every 3-5 years. Do not apply fertilizer to frozen ground or dormant turf. Only use what you need – more is not always better.
