What is the meaning of core aeration?
Core aeration, also known as plug aeration, is the process of using a machine to remove 2-inch to 4-inch soil plugs from your lawn. These plugs are left behind to break down and enrich the soil, while the holes improve airflow, water, and nutrient penetration for stronger grass growth. After aeration, the soil becomes loose, which can cause it to dry out quickly. It is essential to water your lawn immediately after aeration to prevent the soil from drying out. Water your lawn deeply, and ensure that the water penetrates the soil to a depth of at least six inches.When is it Not Recommended to Aerate Your Lawn? Your lawn needs time to adjust and regrow after aeration, which is why winter should be avoided as your lawn is in its dormant state. Grass simply won’t grow and thrive if the ground is very wet or cold.For best results, aerate lawns when the soil is moist. Avoid aeration when soils are dry or wet. The tubes or tines will not be able to penetrate deeply when the soil is dry.If you don’t have an aerator, a simple garden fork is one of the best tools for the job. Simply push it into the soil every few inches, wiggling it to loosen the ground. Water your lawn a day before aerating to soften the soil, and make sure to work methodically to cover the entire lawn.A lawn aerator is a workout to use but the results are really worth it. Aerating your lawn just once per season will improve the quality of your soil, reduce compaction and will set your grass apart from the competition. Right after aerating is a great time to fertilize or apply biostimulants like Essential-G.
How deep should core aeration go?
The ideal lawn aeration depth typically falls between 1 to 6 inches deep with a spacing of 2 to 6 inches between the plugs. However, it’s important to tailor your aeration depth to your lawn’s specific needs. Take into account factors such as soil type, grass variety, and the presence of thatch. Standard core aeration removes plugs of soil 2-3 inches deep, which is ideal for most lawns. However, going beyond this depth can lead to aeration overload, as it may disturb the structure of the soil beyond what is beneficial for root growth. Timing: aerating during the wrong time of year can stress your lawn.After aeration, it is best to avoid heavy traffic on your lawn for at least two weeks. The holes created in the soil need time to heal and settle, and heavy traffic can cause further damage to the grass. Avoid parking heavy equipment or vehicles on your lawn during this time.For best results, aerate lawns when the soil is moist. Avoid aeration when soils are dry or wet. The tubes or tines will not be able to penetrate deeply when the soil is dry. The tubes or tines may get plugged with soil when the soil is wet.Together with proper lawn care, heavy rain can actually benefit your lawn after it’s been aerated, and aerating can help improve lawns with poor drainage. However, torrential rains and flooding may potentially cause damage so soon after aeration, including: Root damage. Loss of nutrients.
Which aeration is best?
Hint: Core aeration almost always outperforms spike aeration. Both aeration methods create holes in your lawn, but you won’t obtain the same results in the long run. Spike aeration pushes soil into the ground, which could worsen things if the soil is moderately compacted. Core aerators will require a little more effort but are generally better than spike aerators. One day before aerating, water your lawn so that the soil is moist and easy to aerate. Soil that is too dry will be difficult to puncture or may crumble, preventing the aerator from removing cores.It’s too late to aerate and overseed your cool-season lawn as the season transitions from late fall into early winter. In many regions across the US, this could be around November. If you live in a frosty area, be sure to aerate and overseed at least 45 days before the first frost.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.It is possible to over-aerate your lawn. While aeration is beneficial for soil health, excessive or improper aeration can cause damage to the grass and disrupt the overall balance of the lawn. Aeration should not be done too frequently.Late Fall Fertilizer Timing (October – November) This last application of fall lawn fertilizer before the winter can make all the difference in the health of your lawn next spring. Taking the time to fertilize in the fall will strengthen your lawn’s roots, giving them a strong base to thrive on next spring.
Is there a downside to aerating?
On the other hand, one drawback of core aeration is that it can be invasive for your lawn. Because professionals mechanically pull up plugs of soil during this process, it can leave behind holes in the ground where those plugs were removed. As a result, it can stress it out. Core aerators will require a little more effort but are generally better than spike aerators. One day before aerating, water your lawn so that the soil is moist and easy to aerate. Soil that is too dry will be difficult to puncture or may crumble, preventing the aerator from removing cores.Within 48 hours after you aerate you should over seed, fertilize, and water your lawn. The seed, fertilizer, and water will have the best chance to get down into the holes made by the aerator if applied soon after aeration.Plug Aerators Are Better Than Spike Aerators Both methods allow for drainage and create more space for roots to grow, but plug aeration causes less compaction and gives your lawn more time to take advantage of the aeration process.The Right Conditions for Aeration The ideal time for aeration is during mild, dry conditions when the soil is moist but not soggy. This allows the aeration tools to penetrate effectively without causing compaction or damage.Soil Type. Consider the type of soil in your lawn. Heavy clay soils benefit most from core aeration, as removing plugs helps break up compaction. Sandy soils may need less frequent aeration and could be suitable for a spike or liquid aeration.
What are the drawbacks of aeration?
Core aeration also breaks up the thatch layer, which consists of dead organic matter between the soil and grass, which can cause problems for your lawn if it becomes thick enough. Fall is considered the best time of the year to seed a lawn and the aeration process allows direct seed to soil contact for maximum germination. Aerating a lawn in the fall also helps loosen the soil prior to the winter freeze/thaw cycles which will help set the stage for aggressive root development come springtime.September: Time to Core Aerate Cool Season Lawn It naturally wants to grow and thrive. This is why it is important we give the grass what it needs to fully recover from the stress of summer. September is a good time to aerate your lawn as part of a healthy maintenance program.Whether your lawn is spongy and diseased or rock-hard and patchy, dethatching and aeration are long-lasting treatments that can work together or separately to improve the flow of nutrients to roots.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.A proven technique is to use plug aerators, which remove a core or plug of grass and soil from the lawn. The excavated soil plugs are allowed to dry and once dry, the soil is broken up through mowing. This is deemed a reliable way to aerate because the process doesn’t create compaction around the holes.
What are the three types of aeration?
There are three different types of aeration an aerator will produce – aerated, laminar, and spray. Each has its benefits. Aerated – Introduces air into the water stream to produce a larger and whiter stream that is soft to the touch and non-splashing. This is the most common residential aerator type. METHODS OF AERATION The most common in industrial use is the water-fall aerator. Through the use of spray nozzles, the water is broken up into small droplets or a thin film to enhance countercurrent air contact.
