What Is the Least Expensive Way to Kill Moss in My Grass?

Moss takes advantage of poor soil conditions to grow on top of grass. Inadequate drainage, compacted soil and low soil fertility contribute to moss growth. Furthermore, yards that receive too much shade often have a moss problem. While moss doesn't harm grass, this weed does ruin the uniform texture of the yard. There are numerous moss-killing products on the market; however, gardeners can save their money by using a less expensive way to control their moss.

Instructions

    • 1

      Rake up moss growing across grass. A more expensive method would be renting a power rake, but gardeners can achieve similar results using hard effort and a rake. Throw moss away.

      Mow the lawn down to its recommended height. Refrain from mowing the grass below that point, because mowing grass too short causes stress to the grass's root system, which creates bare areas for moss growth. Vigorously growing grass prevents moss growth.

      Use a rake to remove excessive thatch. A more expensive way would be renting a power dethatcher. Lawns with a thatch layer over 1/2 inch are subject to moss growth. Thatch is a layer of living and dead organic material. When thatch is allowed to accumulate, it provides moss with a moist environment to grow. Rake up the thatch debris from on top of the lawn.

      Spike the soil using a garden fork to improve soil drainage. Core aerators are more expensive to rent than using a garden fork. Press the garden fork into the soil to create small holes, which helps increase drainage and air flow for grass growth.

      Water the lawn with 1 inch of water a week. Refrain from watering if your grass has received 1 inch of water through rainfall. To find out how much water your grass has received, place tuna cans in the yard. Measure the water accumulation in the tuna can before watering.
