For a lush, deep green appearance, consider using a slow-release organic fertilizer with a small amount of iron, such as Milorganite, which is also environmentally friendly.
A drought can cause your lawn to turn yellow and eventually die. To counter this, either water your grass more frequently using less water, or less frequently but with more water.
Grass seeds can aid in extending your lawn, filling in any bare spots, and revitalizing bare or dead areas. For optimal results, it's best to sow seeds in spring or fall.
It's important to regularly test your soil to ensure a pH level between 6.5 and 7.0. This will help your grass absorb the necessary nutrients and maintain its green color.
Weeds are a common threat to grass, so it's important to eliminate them without harming the grass. Consider organic weed killers or organic gluten cornmeal for this purpose.
