Golf course aeration is the annual practice of punching small holes into the turf. Aeration is meant to provide more room for grassroots to grow and keep the common Bermuda grass turf healthy. These holes allow fresh air to get underneath the green and allows excess soil water to evaporate.
What is golf course aeration and why is it important?
Think of golf course aeration as preventive maintenance: It's the (typically) annual process of punching little holes into greens (and sometimes fairways) that opens up growing room for grass roots and helps keep the turfgrass healthy. (It's also called "aerification.")
Why don’t golf course superintendents aerate?
It may come as a surprise, but golf course superintendents also dislike aeration. After all, the last person who wants to disrupt the smoothness of the putting greens they work so hard to maintain is the superintendent. Golfers often ask, “Why is aeration needed so often?”

What does aerating a golf course do?
Putting greens receive more traffic than any other playing surface. The aeration process helps relieve the compaction caused by all that traffic. It also helps create a firm, smooth putting surface by controlling thatch and promoting healthy turf roots.

The holes punched during aeration are smaller and the greens heal more quickly than the old days of course maintenance. Still, there is no denying that recently aerated greens play differently than greens in peak condition. They roll more slowly and the punched holes can knock a putt off line.
How often should you aerate a golf course?
Many golf courses will aerate two or three times in a given year. However, aeration is only done when turf is healthy and actively growing, so as to promote a speedy recovery. grasses such as bermudagrass and paspalum, core aeration is best performed in late spring and throughout the summer.

It can take up to a couple of weeks for the greens to recover, but these procedures are critical for the long-term health of the greens. This is typically done one to three times a year, depending on the course, the type of greens, and in what part of the country they are located.
Why do they poke holes in grass?
It's important to aerate – essentially, poke holes in – your lawn at least once a year.

We bet you'll see thicker grass growth and healthier color in your lawn just a week or two after you aerate.
How often should you hollow tine?

What happens if you don't aerate greens?
Without aeration, organic matter (i.e. bacteria and other plants) build up on the surface of the turf. This increase in the concentration of plant matter can prevent water from draining into the soil and can reduce the amount of oxygen that reaches the roots, which ultimately limits growth.
What is the difference between aeration and Aerification?
Aeration (also called aerification or aeriation) is the process by which air is circulated through, mixed with or dissolved in a liquid or other substances that act as a fluid (such as soil). Aeration processes create additional surface area in the mixture, allowing greater chemical or suspension reactions.
What happens if you don't aerate your lawn?
Deprived of their basic needs by compacted soil, lawn grasses struggle in stressful situations, such as heat and low rainfall, and lose their healthy, rich color. Grasses gradually thin and eventually die out completely, for lack of the oxygen, water and nutrients available just inches away.

How many times do golf courses aerate?
Many golf courses will aerate two or three times in a given year.
Why is golf course soil compacted?
Compacted soil, created from foot traffic, weather and other factors, reduces oxygen levels in the soil and can inhibit water getting to turf roots. All of this compacting and organic matter can also make for a softer golf course because it's unable to drain water and push new turf to the surface.
