What is the difference between a plug aerator and a core aerator?
Core Aerators: Extract small soil cores, reducing compaction and boosting air/water movement. Plug Aerators: Remove larger plugs for more aggressive soil restructuring – ideal for heavily trafficked or severely compacted areas. Plug aerators are incredibly effective and promote lawn health. Because they penetrate deeply into the soil, they create long-lasting, nutrient-rich soil that ensures healthy grass growth.Plug aerators, also called core aerators, have hollow tines and remove plugs of soil from your lawn. Spike aerators have rollers with solid spikes that puncture holes in the ground. Spike aerators will punch holes in the lawn as you go, while core aerators will remove plugs of grass and soil.The Downside: It Looks Rough for Short Time Immediately after aeration: your yard will be covered in small dirt plugs. Hundreds to thousands of them (depending on the size). They don’t look great. This is temporary.Advantages of plug aerators: More effective at relieving soil compaction. Improves root development and overall turf health. Allows water and fertilizer to penetrate deeper into the soil. Provides longer-lasting aeration results.
How does a plug aerator work?
Plug aerators remove a core or plug of grass and soil from the lawn. For the best results, use an aerating tool or machine that actually removes plugs of soil. Poking holes is less effective and can actually cause additional compaction in the areas around the holes. Core aeration provides numerous benefits for your lawn, making it an essential part of regular lawn care. Here are the top seven reasons why you should consider aerating your lawn: Relieves Soil Compaction: Soil compaction restricts air, water and nutrients from reaching the grass roots.Aeration Mistakes: Uneven Lawn from Excessive Aeration Too many soil plugs can leave your lawn uneven and rough. That makes mowing difficult and causes patchy water coverage. Pro Tip: Allow recovery time between aerations so the soil can settle naturally.While not crucial, it is recommended to aerate your lawn before fertilizing or overseeding. It is important to make sure the soil is loose enough for seeding so the roots can grow deeper for better water and nutrient access.For highly compacted soil or soil that hasn’t been aerated in more than a year, make two passes with the aerator: one following your mowing pattern, and the second at an angle to the first. Aim to create 20 to 40 holes per square foot.There are two methods for aerating your lawn — spike aerating and plug or core aerating. Spike aerating requires simply poking holes in the soil, creating space for air and water. Plug or core aerating involves removing cores from the ground, pulling up chunks of soil entirely and leaving small gaps in the lawn.
What are the two types of aerators?
The two primary types of lawn aerators are plug aerators and spike aerators. Plug aerators, also called core aerators, have hollow tines and remove plugs of soil from your lawn. Spike aerators have rollers with solid spikes that puncture holes in the ground. Deciding between these two methods depends on the specific needs of your lawn. If your soil is heavily compacted or clay-based, core aeration might be the best option. If your lawn has light compaction and you prefer a quicker solution, spike aeration can be effective.Why is core (plug) aeration generally recommended over spike aeration? Professional landscapers consistently choose core aerators because they deliver superior long-term results for your lawn’s health. While spike aerators can loosen soil temporarily, they often create more problems than they solve.Ross says that spike aerators are best for small lawns or small patches you plan on aerating several times a year. He also recommends plug (core) aerators for all lawn types, including heavy clay soil and large lawns.Never aerate dormant lawns. For cool-season grasses common in northern lawns, early fall or early spring are the best times for aerating. For warm-season grasses common to southern lawns, the best time for aerating is late spring or very early summer.
Which type of aerator is best?
Types of Aerators – Spike Versus Plug Aerators Spike aerators are suited for smaller lawns that are mildly compacted while plug aerators are ideal for larger and more compacted lawns. Plug aerators open the ground up to more ventilation compared to spike aerators. Core aeration comes ahead of spike aeration because it yields long-term results in small- to large-sized lawns, and can counter moderate to severe soil compaction. The removal of soil plugs allows roots to absorb more water, oxygen, and nutrients. Following this, your grass will grow denser and greener.The best time for aeration is during the growing season, when the grass can heal and fill in any open areas after soil plugs are removed. Ideally, aerate the lawn with cool season grass in the early spring or fall and those with warm season grass in the late spring.If you want to go the extra mile for your lawn, you should schedule core aeration twice a year – both in the spring and fall! When you do, it’ll result in even healthier, more resilient grass. Not only that, but it’ll also help it stay lush and green throughout stressful times of the year, while other lawns won’t!It’s best to fertilize right after aerating and seeding, allowing the fertilizer to sink into the aeration holes ensuring deeper soil penetration. Proper fertilization encourages a lush, green, healthy lawn that stands out and offers a beautiful outdoor space for relaxation and play.
What does a coring aerator do?
Core aeration for lawns is a mechanical process, which extracts cores of soil, thatch, and grass from the surface of the lawn to increase nutrient availability, water penetration, soil air exchange and reduce compaction. You want to aerate the lawn when your grass is in its peak growing period so it can recover quickly—think early spring or fall for cool-season grasses, and late spring through early summer for warm-season grasses. If you have high-traffic areas or heavy clay soil, you will want to aerate every year.After you’ve had your lawn aerated, you can expect to see results within a few weeks. Because core aeration helps to loosen compacted soil and allows essential resources to reach the roots of your grass more easily, your lawn will begin to look healthier and more vibrant shortly after the service is complete.In most cases, aerating is best before laying fertilizer as it allows for more oxygen and deeper growth of grass roots. If you have compact soil or clay soil, it is especially crucial to aerate before so that the fertilizer reaches deeper roots.How often should I aerate? Aerate your turf once every 1–5 years for optimal growth. Turf on heavy soils or suffering from heavy foot traffic will benefit from more frequent aeration.Is late October too late to aerate? It can be, depending on the weather and your grass type. Aeration should be done while grass is still actively growing and before the ground cools too much. If frost is approaching or the grass has gone dormant, you’ve missed the perfect conditions for recovery.
Is core aeration better?
Core aeration is the method of choice for lawn pros because it effectively loosens the soil, giving root systems access to nutrients and keeping soil more nutrient-rich in the long term. Core aeration will leave your yard freckled with little holes, but they’ll fill in with denser, healthier grass. Core aeration is the preferred method for long-lasting lawn health. However, spike aeration may be the way to go if your lawn is mildly compacted and you’d like an inexpensive DIY fix to spur grass growth.
