An organic lawn grows beautifully, is safe for you and your family [pets and wildlife included] and needs minimal care.
Growing a healthy and safe lawn is as simple as using common sense—organic common sense, that is. If you build the soil and use a few basic cultural techniques, you'll have a lush stand of turfgrass without harming kids, pets, wildlife, the water supply, and the rest of the environment. Here are three easy steps to get started on a thick, green organic lawn.
Mow high
The simplest way to help your organic lawn grow up healthy and dense is to adjust your mower's cutting height to its highest setting. Why? Tall blades of grass have more surface area exposed to the sun, enabling them to photosynthesize more sugars and starches for greater root growth. Greater root mass means better access to water and nutrients, so plants are more tolerant of drought and can recover more rapidly from dormancy.
Leave the clippings on the lawn
As grass clippings decompose, they contribute valuable nitrogen to the soil, almost 2 pounds of nitrogen per 1,000 square feet of soil each season or about half of the lawn's annual fertilizer needs. They also add organic matter and provide a variety of other benefits to the soil and grass. Many people believe, however, that clippings left on the lawn contribute to thatchdead or dying grass parts [such as stems, stolons, crowns, and roots] that form a layer on top of the soil and obstruct moisture and oxygen from reaching plant roots. But just the opposite is true: Fresh clippings stimulate earthworm activity, which breaks down thatch.
Fear no weeds
You'll leave no room for weeds if you mow your grass often [but not too low] with a sharp blade and grow it in soil that's rich in organic matter and biological activity. Researchers at the University of Maryland confirmed that mowing cool-season turfgrasses to 3 inches high works as well as or better than herbicides for suppressing crabgrass. In my experience, dandelions, common purslane, and other low-growing annual weeds also do not survive in a lawn that's cut high.
