- If you must fertilize, September is the best month. And be sure to use slow-release fertilizer.
- If you want to fertilize more than once, don’t fertilize in the spring until you have mowed the lawn three times.
- More is not always better! Skip the “step programs” offered by many lawn care companies, and be sure to apply fertilizers and pesticides only as directed. Using less will save you money, too! If you do use a lawn care company, ask them about their environmental options and certifications.
- Go natural: mow high and leave grass clippings on the lawn. It helps improve the lawn’s health and quality, and you’re less likely to need fertilizer.
- Avoid using fertilizers or pesticides near wellheads or within 75 feet of waterways.
- Check the weather forecast before applications, and don’t apply fertilizers or pesticides when there is rain predicted.
- Avoid using combination fertilizer/pesticide products. Hand pick weeds when possible, and if you must treat weeds or insects with pesticides, spot treat them rather than dousing the entire lawn.
