What is a better way to care for my lawn?
First of all, the amount of lawn we maintain should be kept to a minimum, to those spaces that provide a functional place for recreation. With the remaining smaller areas of lawn there are a number of ways we can reduce their impact on the environment.
Mowing: For healthier lawns, the grass shouldn’t be cut shorter than 3”, as this promotes longer roots that can absorb more water, and taller grass shades out weed seeds. Grass clippings should be mulched and left on the lawn to provide a natural fertilizer as it breaks down. In addition, mow with a sharp blade and mow when the grass is dry.
Watering: Water lawns less frequently but deeper, so the water penetrates deep into the soil to encourage root growth. Water early in the morning to minimize evaporative loss, and make sure the sprinklers only water the lawn (not the street or sidewalk!).
Chemicals: Avoid the use of synthetic fertilizers and pesticides. In addition to polluting the water and killing many beneficial insects, these chemicals kill the naturally-occurring biota in the soil that are required for healthy plant growth. Instead, top dress with compost annually and, if you must, consider organic alternatives. Finally, accept a certain level of insects and “weeds” in your lawn.
Consider lawn alternatives: “No mow” grass mixes are growing in popularity. These mixes, such as Pearl’s Premium [emphasis added], grow slowly, therefore requiring less frequent mowing (often monthly). Buffalo grass (Bouteloua dactyloides) is an attractive, short native grass that does well in sunny sites. Sedges, such asCarex pensylvanica, can be used in more shady sites. Shortgrass meadows, or those mixed with wildflowers, can also be an attractive lawn alternative.
