CGL Landscaping professionals know the secret behind your lush green grass. Overseeding in Phoenix is a part of an inclusive, proactive plan that keeps your lawn looking great. We offer exclusive Phoenix lawn overseeding, with years of experience to guarantee a beautiful lawn for  years to come.

As grasses grow, it is normal for them to lose ground, especially if it is heavily trafficked. Overseeding is spreading grass seeds over an existing lawn that keeps your yard competitive and imbued in vigor and youth. Our professional landscapers undergo exceptional overseeding in Phoenix that prevents thinning. 

Overseeding warm-season grasses with cool-season reinforcements bring green color through winter to lawns in the southern areas. Overseeding in Arizona with a premium, cool-season ryegrass, such as Pennington Perennial Ryegrass, offers a temporary green lawn when the regular, warm-season grasses are dormant.

Steps Involved in Overseeding Your Lawn

The Scalping

You need to eliminate the competition from your summer lawn and decrease the thatch that has accumulated over the summer to ensure a good overseed for the winter. This is achieved by scalping and de-thatching, which removes the accumulation of leaf and thatch to ensure that the seed gets down to the soil.

The Seeding

The higher the quality of your grass seed Phoenix homeowners choose, the greater your lawn quality would be. We suggest grasses such as perennial ryegrass, that are suitable for the desert climate of Arizona.The amount of seed that you will require depends based on how lush you like your lawn and the standard grass height that you are planning, for instance:

  • 12 pounds per 1,000 square foot for Home
    Lawns (1′-2′)
  • 15 pounds per 1,000 square foot for Home
    Lawns (1⁄2′ – 1″)
  • Fertilization

    Prior to turning on your water, we make sure to fertilize the land with a starter fertilizer. A 6-20-20 (6 percent nitrogen, 20 percent phosphorus, 20 percent potassium) or 15-15-15 (15 percent each of nitrogen, phosphorus, and potassium) combination is usually considered.


    This step is optional but can be vital if you (1) do not have a good irrigation system, (2) do not have a timer that would water 4-5 times per day, or (3) the temperatures have cooled too quickly. A well-composted mulch will help retain the moisture and heat necessary to germinate your perennial ryegrass. After the seed has been spread, the mulch 1/8″ to 1/4″ thick is spread evenly over the whole lawn area.


    watering is critical. Watering is important for a period of seven to ten days to maintain a moist seedbed until the seeds start to germinate. The land would need to be watered 4 to 5 times per day so that there are no dry spots left. Watering may be reduced to 2-3 times per day after the seed has germinated and grown to a height of ¾ to 1”. After 10 to 14 days, watering time can be reduced to once a day. However, you can water every other day through the winter once your winter lawn is established. However, depending on the requirements of the lawn, you may need to begin watering every night when the temperatures start to rise in the spring.


    After the 10th to 14th day of germination, the first mowing should be done. Mowing is done with the 30% rule to make sure the new young seedlings are not pulled out. Once the ryegrass is established, the regular maintenance program is carried out by our experts.

    The best time to overseed your sod grass lawn in Arizona is during the first two weeks of October or when the evening temperatures start remaining below 65 degrees. Although it takes a little effort for Phoenix lawn overseeding, we assure you that you will enjoy our performance.
