How Far Apart Should Aeration Holes Be?

How far apart should aeration holes be? Aerating Guidelines

Aerator holes should be 3 inches deep, 3 inches or less apart, and about 3/4 inch in diameter. Several passes may be required for correct spacing. Aeration frequency depends on soil type, thatch, and traffic, among other factors.

Can you over aerate a lawn?

Especially thick types of grass may also call for aerating more frequently. As a general rule, you shouldn't need to aerate more than once a year at any time ("too much of a good thing" applies here, since you don't want to damage your soil).

How far apart should you core a lawn?

Simply insert the fork into the lawn and wriggle it back and forth to fracture the soil profile. Aim for a spacing between the holes of around 8 – 10cm. In order to achieve adequate aeration, you may need to go over the area twice in a different direction each time.

Should I mow before or after aeration?

In general, aeration creates the most benefit on soil that is a little bit moist. Then, try not to mow right after aerating. Instead, mow beforehand, and consider laying seed and fertilizer over your lawn after aeration and give your lawn time for that new seed to germinate before you mow again.

Should I rake my lawn after aerating?

Coupled with foot traffic and rainfall, the soil below the thatch slowly becomes more compact -- a dense soil structure hinders water and air pocket retention while causing stress to the grass itself. You should not rake the lawn after aeration unless you are breaking down the removed cores.

How do I prepare my lawn for core aeration?

Prior to aeration and seeding, a lawn should be mowed at a height of 1.5 to 2 inches. Any clippings left on the lawn after this close cut, should be bagged, blown or raked off the lawn. This is necessary to maximize seed to soil contact as the seed is spread. This is a key factor in successful germination.


Should you water right after aerating?

Your lawn's watering needs immediately after aeration and overseeding are going to be a bit different than what you might be used to. Your lawn is going to require less water but more frequently. You need to keep the soil moist but you don't want to water for too long.


When should I fertilize after aeration?

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. If the fertilizer contains weed control, your grass seed won't germinate properly.


Do you scarify before aerating?

When considering both aerating and scarifying, it's better to scarify first, then aerate- but leave a few days in between the two exercises to allow your lawn to recover before you put it through all that work again.
