How to Keep Grass Green


A vigorously growing, healthy lawn will display a rich, green color with resilient blades. Its vibrant growth and color will provide a stunning visual impact that demands attention. Achieving and maintaining a green lawn requires some attention and general maintenance. Once the brilliantly green lawn is achieved, maintaining the color becomes a simple process.

Step 1

Begin caring for the lawn in the early spring, just after the final frost. Rake the lawn to collect any debris and leaves that remain from the previous year. Dispose of the debris and never use it as compost or mulch.

Step 2

Aerate and dethatch the lawn to promote increased air circulation and improve sunlight penetration. Remove excessive thatch from the lawn but leave a 1-inch layer of thatch behind to provide root protection. Use a dethatch machine or complete the process manually with a rake. Scrape the areas just below the grass blades but above the soil surface to remove the unwanted debris.

Step 3

Complete the aeration process while the lawn is moist but not wet. Use a power or manual aeration machine to complete the process. Aerate in the same direction as you mow to maintain a consistent pattern.

Step 4

Irrigate the lawn deeply and infrequently to promote a deep, strong root system. Provide the lawn with 1 to 1 1/2 inches of water using a slow irrigation process, about once each week. Set sprinklers and irrigation systems for low-pressured distribution. If using a water hose, use a low pressure to apply water. Adjust the irrigation levels during periods of rain and drought.

Step 5

Feed the lawn two to four times each year to promote lush green growth. Use a well-balanced, slow release fertilizer with higher levels of nitrogen, such as a 20-20-20 or 40-40-40 combination. Select a fertilizer that is designed for the type of grass that will be fertilized. Distribute the fertilizer evenly and apply on cool days when temperatures are below 85 degrees F. Water in thoroughly after application. Never over-fertilize, as this will cause root and blade burn.

Step 6

Mow the lawn regularly so that no more than 1/3 of the blade is removed during one cutting session. Keep the lawn between 2 1/2 and 3inches in height during the summer months. Reduce the height by about 1 inch during the spring and fall months. Maintain sharp mower blades for a healthy cut.

Step 7

Keep the lawn free of weeds. Treat the lawn with a pre-emergent herbicide in the early spring to reduce the potential for weeds. Pull any developing weeds by hand as they appear. Remove the entire root from below the surface to prevent regrowth.
