When, Why and How to Aerate Lawn

Aerate Lawn

Lawn aerating is one of the most effective ways to keep your lawn nutritious, powerful, and full of life. Lawn aeration entails removing soil plugs from your lawn, resulting in deep spots that promote healthy growth for your roots. The space that is created by removing the plugs allows your garden’s rootstock to widen and strengthen. Aeration also improves water flow and provides easier access to plant food and nutrients for your plant roots. This article will explore lawn aerator tips and provide information on how to help you get a beautiful lawn.

What Is Lawn Aeration?

Thatch is the scattered, organic layer of dead and living material in the grass that develops between the green plant area and the soil area: it is made up of shoots, the stems, and the roots. When grass creates organic waste quicker than it can be degraded, thatch builds up. Thatch isn’t always a terrible thing. In lawns, a thin coating of thatch acts as insulation against severe temperatures and soil moisture changes. However, upwards of an inch of thatch might cause issues. Too much thatch can trap too much water, reducing the amount of oxygen available to grassroots. By hosting disease-causing organisms and insects, it can further exacerbate pest problems. The accumulation of grass thatch obstructs your grass’s ability to breathe. Aeration of the grass in the spring or fall helps to reduce thatch. Aeration of the grass can be as easy as digging holes in the soil in between (so-called “spiking”), but this is only effective in minor thatch build-up situations. This haphazard technique will not suffice for individuals in desperate need of lawn aeration: core aeration is required. In the fall, instead of merely skimming the autumn leaves off the top of the grass, you should rake thoroughly to eliminate as much grass thatch as possible.

Lawn care aeration also helps to break up compacted soil, allowing water, ventilation, and minerals to reach the root zone. Lawn aeration is required more regularly in grassy areas subjected to continual foot traffic (or, worse, auto traffic) than in out-of-the-way regions.

When to Aerate Your Lawn?

Aerating lawns should be something done during the grass’s peak growing season to allow it to recover fast. For warm-season grasses, aeration can be done in the spring and early summer.

However, for lawns with cooler-season grass, core aeration should be done in the early spring or late fall. If your grass is in good shape and you don’t notice any problems, you can aerate between two to three years.

Aeration is also indicated by the following signs:

  • Your lawn sees a lot of traffic on a daily basis.
  • Your grass has more than a half-inch of thatch.
  • You have a clay-rich soil.

How to Aerate?

A grass core aerator may be simply rented from a large box retailer or a rental facility. Renting rather than buying an aerator makes more financial sense because you should not need to aerate your grass very often. This lawn aeration machine pulls soil plugs, or “cores” (as the name implies), out of the soil, allowing air to circulate. The depth of these plugs must be up to three inches. Every three inches, a plug like this should be removed out of the lawn. Watering the grass the day before will help with the clog removal procedure, but not to the point of watering down the soil. After aerating, water every two to three days.

Rent a vertical mower from a rental facility if your thatch problem is serious (about, 3/4 inch thickness or more). However, you might hire a lawn service to aerate your grass for you. Sodding Canada provides great lawn aeration services for you and your home from raking leaves to additional dethatching.

What to Do After Aeration?

After aeration, lawn maintenance is critical, and fortunately, it’s pretty simple.

Allow the soil plugs to disintegrate and trickle back into the holes created by the aeration machine on the grass. Within two to three weeks, your lawn mower will start breaking them up and support to work them deep into the ground.

To get nutrients into your grass roots, use fertilizer right after aerating your lawn. This helps the grass prepare for the summer heat. Having a lush, healthy grass also helps to keep weeds at bay.

Re-seed your lawn, particularly in places where the grass is thinning. Following aeration, the seeds mingle with the soil plugs and have easier access to non-compacted soil.


Should you overseed after aeration?

Combining a core aeration with overseeding is the best method to get the most out of both treatments at the same time. After a lawn has been aerated, overseeding it creates an open channel for seed to permeate the soil and ensures good seed to the soil contact.
The new seed may sprout and establish itself considerably faster since the removed cores have helped ease soil compaction and thatch formation. The ability to absorb oxygen and water is also improved, paving the way for new, strong roots and nutritionally full soil. You’ll get the most out of both treatments by prioritizing seed-to-soil contact with a mixed aeration and overseeding treatment, giving your grass the best opportunity of growing lush, strong, and vigorous before the Winter season.

Can you aerate too much?

It’s more a case of doing it when it’s not required. Clay soils, for example, should be aerated at least twice a year. If you’re going to do it on a regular basis, one run will be enough in the future. A decent rule of thumb is to thump once a year.

Can you mow lawn after aeration?

If you don’t know where your sprinklers and pop-ups are, you can end up damaging them while mowing. Furthermore, watering the grass before aerating it is a good idea since aeration is most efficient when the soil is somewhat damp. Mowers and lawn rollers are often used to maintain connections between newly put sod and soil, so always aerate after mowing or putting sod to help loosen the newly compact soil on your lawn. After you’ve planted your seedlings, they’ll need time to grow and the correct atmosphere to thrive. Before the first mow, they’ll need to adapt and establish roots, so don’t mow for the first two to four weeks after aerating and overseeding. The length of time depends on your location and the sort of grass you planted. A lawn care specialist can help you choose the best timeframe. Give us a call if you need more tailored advice on aftercare.

Should I fertilize or aerate first?

Fertilizer works best when it reaches deep into the soil, where it can be accessed by grass roots, therefore aerate before applying fertilizer to produce the holes necessary for fertilizer to penetrate effectively.

It is not by chance that you get to have a beautiful lawn. Every homeowner dream of having a lush lawn like those found on golf resorts and major league stadiums. Many homeowners, however, overlook the fact that maintaining a lawn needs the same care and understanding as a farmer producing a revenue crop. The more you understand about what your grass needs to grow, the more likely you are to achieve the lush surface that will make your friends jealous. when the soil gets compacted it suffocates your root system, resulting in developmental problems, dull colour, and an unappealing appearance to your lawn. Too many particles are packed together in compacted lawns, reducing water, air, and fertilizer absorption. High-traffic areas are prone to compaction, but any yard may be revitalized by paying close attention to the grass structure.
