How long After Aerating Should You Fertilize (And Why)?

Exact Answer: One Day

While having a lawn, it’s essential to take care of the lawn. With proper care, one can get the most fruitful results out of the lawn. There are three keys to a proper routine of lawn care. The first step is aeration, which is followed by overseeding. After overseeding, the final step is fertilizing.

Aeration is the foremost and most important step. A machine is used for this purpose which is made to travel throughout the lawn. Plugs are removed from the soil, thereby loosening the soil. This process helps the soil absorb more air, nutrients, and fluids, thereby making it more fertile. After proper aeration, the soil is ready to germinate seeds. The next step that is overseeding, is carried out in cool weather.

How Long After Aerating Should You Fertilize?

Aeration is the key step to a proper routine of lawn care. If the soil is compacted, then the growth of the grass in your lawn won’t be noteworthy. Hence, it is essential to aerate the lawn. After aeration, you can notice that the growth of grass is better than the previous one. The grass would not only be thicker but also healthier. During aeration, holes are created in the soil, which allows the easy exchange of water, air, and nutrients between the soil and the environment.

Most people wonder when it’s the correct time to aerate the lawn. The correct time would be the time when you wish to go for seeding it. However, it also depends on the grass you want to grow. The condition and weather should be favorable for the development of grass. However, if someone tries to aerate the soil during the growth of the grass, then slow aeration should be done. In this way, the grasses won’t be hurt due to the roughness of the process and would recover from the shocks of the process soon.

The ideal time to fertilize after aeration is one day. However, if there is any delay, it must be ensured that fertilization is done within three days.

Why Does It Take That Long After Aerating To Fertilize?

After aeration, a fertilizer with a high amount of nitrogen and other nutrients should be used. After aeration, the soil is the most fertile. During this time, the lawn should be corrected for repairs. After this, one can sow seeds and can wait for fertilization. This is the best time to sow seeds as the roots would have the privilege to get easy access to exchange water and nutrients. This promotes the growth of the grasses in the lawn.

Within two days of aeration, the holes provide the best medium of exchange of all those materials, which would be helpful for the development of the seed. A good amount of fertilizer should also be used. Properly aerated soils even have better drainage facilities. Apart from this, it decreases the chances of weeds and even prevents the deposition of thatch. Aeration even makes the soil capable of taking up more fertilizer, thereby promoting the growth of grasses.

It is always advised to maintain a minimum time gap of about one day between aeration and fertilization. This is because the soil would be left out open to breathe. It would make the soil more productive, thereby ensuring that it yields the best results after this period. Hence, it is essential to maintain the time gap lest the productivity and efficiency of the aerated soil would be reduced. However, one should also be perfect while carrying out these processes. After choosing and getting the appropriate instruments, it is essential to know how to use them properly.


Finally, it can be concluded that one should take proper precautions while going for aeration and seeding. The most important thing is to choose a suitable time during the day to aerate the soil. Dry seasons are the preferable ones. However, if your lawn is facing a drought, it is best to have patience until the first rain. 

On average, a one-day time gap is a must between aeration and fertilization. Insufficient water supply would even pose problems for the germinating seed, thereby making development a difficult process. After sowing seeds, one can’t sit idle waiting for results. It is advised to make prior preparations to fight against weeds if any such appear.
