Grass needs space! lots of space! But not where you think it is. You need an underground space. It needs space to absorb air, nutrients and water. Simply put, the roots of grass must ‘breathe’.
What is lawn aeration?
Golfers always do it! This is one of the reasons why golf courses always look better than the surrounding area. Small branches (spikes) built into the soles of your shoes can help you swing: It not only holds the feet in place as golfers walk, but also drills holes in the ground. That perforation vents the ground allowing the grass to ‘breathe’.
Why do I need to aerate my lawn?
Ultimately, it helps to give the grass some air and allow it to breathe. A healthy lawn can lower the temperature around your home, saving you energy costs. However, ventilation also helps protect the lawn from many common problems with compression. These can include drainage problems, fungal diseases, and weed infestation.
Aeration helps the roots grow deeper and produce a stronger, more vibrant lawn. The main reason for aeration is to relieve soil compaction. Soil compaction limits the amount of nutrients and water that penetrates the grass roots.
How can I ventilate my lawn?
There are different techniques depending on the size of the grass and the amount of energy it can contribute. Here are the three most common methods.
1/ Aeration roller
Aeration rollers are available in a variety of sizes and the largest rollers require a full tractor to tow. If you have a ‘ride-on’ yard, you can find a size that suits you. But if you’re a ‘push-more’ sized yard, you’ll provide a repulsive horsepower similar to the one pictured above.
Spike rollers are also useful for turf aeration to improve drainage or pH by incorporating lime, gypsum or coarse sand into the profile.
If you do not want to purchase a roller, check with your nearest tool rental store. They will probably have what you need.
two/ aerating sandals
If you often do outdoor activities, you can keep a smaller lawn area by wearing breathable sandals. These are sandals with spikes similar to golf shoes, which blow air into the grass as you walk. They’re cheap and effective, but to get the job done, you’ll need to completely miss others without belting them often and walking in the same area.
this old garden fork
If you need exercise, go here! Simply push the tines into the ground and shake them back and forth to break up the soil profile. Ideally, aim for about 10 cm (1″) between each set of holes. For best results, plan to navigate the area twice in different directions each time (eg NS first, EW second).
You can also purchase a vent fork that is specifically designed to remove the dirt plug each time you insert it.
Unlike regular aeration, where solid tines simply drill holes in the ground, core aeration simultaneously removes dirt from the lawn. This is a technique called core aeration and should only be done when the grass is actively growing so that it can recover quickly.
Immediately after core aeration is a great time to put on a top dress with washed river sand. The sand fills the hole and drains freely and allows air and water to permeate due to the open structure.
Of course, all forms of aeration are best done after rainfall, when naturally hard soils are prone to penetration.
How often should I ventilate my lawn?
Other soil types require more frequent aeration. Clay soils compact easily and should be aerated at least once a year. You can aerate the sandy lawn once a year or once every two years. In harsh climates, twice a year ventilation is beneficial for lawn growth and health.
Compression is a common problem in areas with large amounts of pedestrians, pets, or cars on the lawn. Regular ventilation is important to ensure that the ground does not become too hard. Aeration helps the soil breathe and the grass spreads.
When is aeration?
It will depend on your climate. Spring and summer, when the grass is actively growing, are best to air the warm season grasses like lotus leaf buffalo, sofa, kikuyu, and joisia. It is recommended to ventilate at the same time when fertilizing and other lawn care tasks (eg mowing or top dressing).
The same principle applies for cool climate grasses such as fescue and rye grass. Ventilation is possible all year round, except in very cold climates.
Aeration is often overlooked, but the importance of allowing air, water and nutrients to enter the soil cannot be overstated.
grass pH test
The pH level affects the ability of your lawn to absorb the minerals and nutrients it needs to thrive. Immediately after aeration is an ideal time to test the pH level and take any necessary action. If your pH is too high or too low, your lawn may not be able to efficiently absorb the minerals and nutrients it needs to stay healthy.
The ideal pH range for lawns is between 6 and 7. Testing the pH level is easy.. You can purchase a pH test kit here.
If you’re not in a position to need your lawn pH, now is the perfect time to apply the right treatment. An example is:
- Lime (calcium carbonate) helps to increase pH and neutralize acidic soils.
- Gypsum is calcium sulfate dihydrate and helps break down clay soils.
- Fertilizer – Immediately after aeration is a perfect time to fertilize your lawn as aeration allows better penetration of nutrients.
As a bonus, if you have healthy, green grass The curb appeal of the house increases its market value. And you will be the envy of your neighbors ?
