To look its best, a lawn should be aerated at least once per year. Aeration is the process of mechanically poking holes in the soil to allow water, oxygen, and nutrients to better penetrate to the roots of your grass.
The best time to aerate your Zoysia lawn is in the spring, just before your grass beings to grow rapidly. Aeration machines are generally available from equipment rental stores.
Aerating your Zoysia Lawn Do’s and Don’ts
- Make sure the ground is soft enough. Water your lawn the day before you aerate.
- Use an aerator with hollow tines which pull up plugs of earth as the machine travels along.
- Use a criss-cross pattern. Direct the machine over the entire lawn, going back and forth in one direction. Then direct the machine to cross over the first set of rows in the opposite direction.
- Put at least 12 holes per two square feet of lawn.
- If you would like to remove the plugs of soil on the grass surface, let them dry a few days, then drag a small piece of carpet across the lawn to break them apart.
- Aerate in late April, just as the lawn is ready for vigorous growth.
- Use solid-tine spike aerators, which provide less benefits to your lawn.
- Aerate if your Zoysia is suffering from drought, the ground is hard and dry.
- Aerate during a dormant growth period.
- Aerate your lawn within the first year of establishment.
