Organic Lawn Care is basically soil science. The goal throughout the process is to create a microbe and nutrient-rich soil system in which to develop deep-rooted, dense turf that competes successfully with weeds, and is low-maintenance, drought, insect and disease-tolerant and beautiful!
Here are three easy steps to get started on a thick, green organic lawn.
1. Cut grass to 3 inches tall all season long. Mowing high is the simplest way to help your organic lawn grow up healthy and dense. Some varieties, particularly fine fescues, fall over at that height and should be mowed a half inch to an inch shorter than other grasses.
2. Remove just one-third of the blade. No matter how tall the turf, avoid cutting of more than one-third of each grass blade in any single mowing, or you risk stressing the grass. Greater root mass means better access to water and nutrients, so plants are more tolerant of drought and can recover more rapidly from dormancy and disease.
3. Keep the mower blade sharp. A dull lawn-mower blade will tear grass, and the jagged wounds make the plants susceptible to infection. We recommend mulching in the clippings. As grass clippings decompose, they contribute valuable nitrogen to the soil, about half of the lawn's annual fertilizer needs. You'll leave no room for weeds if you mow your grass often with a sharp blade and grow it in soil that's rich in organic matter and biological activity. But we caution you not to leave clumps of clippings on top of the lawn.
