Your grass endures mother natures full force, year in and year out. Excessive heat and cold can test your lawn’s ability to grow and survive into dormancy. For that reason alone you should aerate your lawn annually.
Core aeration creates gaps in your turf to allow more air and water to reach the root system.
Aeration also requires specific timing. The time of year you tackle aeration and how often you aerate depends on grass and soil type. The question remains when to aerate your lawn?
Know Which Turf You have
In Texas the warm-season grasses begin their period of active growth in the late spring. If you aerate your lawn in late spring to early summer, the following period of rapid growth will quickly fill in the holes you create.
Top 3 types for Grass
- Bermuda: A good all around grass that is heat tolerant and can handle foot traffic. Great for golf courses, sports fields, and lawns with lots of kids.
- St. Augustine: is a great choice for both home or commercial lawns. Texas native grass is a well-rounded, drought, cold and shade tolerant grass.
- Zoysia: is a fine-bladed grass that grows a thick lush lawn. Its dense growth pattern allows it to choke out weeds and provides a more uniform appearance.
Aeration According to Soil Type
- Various soil types require more or less frequent aeration. Clay soil compacts easily and should be aerated at least once a year.
- You can aerate a sandy lawn once a year, or you could alternating years. In arid and dry climates, aerating twice a year will promote turf growth and health.
- Aerating prior to fertilizing or reseeding your lawn is recommended. Aeration creates openings for nutrients and seed to penetrate deeper into the soil.
- Do not aerate lawns that are less than a year installed with fresh sod. Aerating will keep the roots from finally maturing and and hinder future growth.
- Weed control is advised prior to aerating, because the process of aerating can spread weed seeds or portions of weedy roots.
- Aerate when soil is moist, but not saturated. To achieve the correct moisture balance, your lawn should absorb 1 inch of water.
- Before you begin to aerate your lawn, water for one hour prior to aerating. When your soil is too hard, water for shorter time period on several days prior to aerating.
- Avoid aerating during a drought or excessive heat. Aerating in these conditions will stress your lawn by allowing heat to the dry soil.
You have a choice to rent out a core aerating machine or call a local lawn maintenance company to provide the service for you. Either option will assist in your lawns continued growth.
