Organic Lawn Care

  • I like having a nice green, weed-free lawn but I don’t feel right about spraying my lawn with chemicals. Is there such a thing as organic lawn care?

    Yes, there is such a thing as having a nice lawn without using chemicals. There are several simple things you can do to get started with an organic lawn. The easiest way to help your lawn grow healthy and dense is to adjust your mowers height to the highest setting. Tall blades of grass photosynthesize sugars and starches better establishing greater root growth. Short grass doesn’t compete well with weeds. You should also sharpen your mower blades. Dull blades tear at grass leaving them more susceptible to disease.

    Leave the grass clippings on your lawn. As grass clippings decompose they provide valuable nitrogen to the soil. They also add organic matter and a variety of other benefits to the soil and grass. If you wish to apply fertilizer, choose an organic fertilizer made of plant residues and by-products of animal processing—blood meal or feather meal. Look for a product with an NPK (nitrogen-phosphorus-potassium) ratio of approximately 3-1-2. Apply no more than 1 pound of nitrogen per 1,000 square feet during each application.
