Aeration, like scarification, is another vital step to keeping your lawn looking healthy and vibrant. It involves making small holes in the soil to allow air, water and nutrients to get into the grass roots, helping them to grow deeply, and produce a much stronger lawn. It also helps to relieve compaction from the soil, which stops nutrients and air from circulating. But how do you aerate your lawn?
Before you start to aerate your lawn, it’s a good idea to scarify it first to get rid of any moss, dead grass and thatch. This involves vigorously raking your lawn to get all the organic matter up, then transferring it to your compost heap or disposing of it. Light scarification is best in the spring but you can heavily scarify it in the autumn.
If you’ve got a small lawn, you can use a hand-held hollow tine aerator or even a normal garden fork. Dig deep into your lawn’s surface with the fork, or push the aerator into the ground which will pull plugs, or cores, of soil out of the ground to create air holes. You can let the cores dry and then go over them with a lawn mower or rake to spread them evenly across your lawn. This will recycle all the nutrients in those parts of the soil and stimulate bacterial activity to break down unwanted thatch. Don’t leave them, because they will make your lawn look bumpy over time.
If you’ve got a larger lawn, you might find it easier to see if you can hire a petrol aerator. But there are also rolling aerators that have spikes on a cylinder and you just push along, or even aerator sandals that you can wear and just go to town on your grass!
