Best Compost Aerators in 2021
Updated 04-08-2021 – Mia Cohen
Let’s be honest, a loaded compost bin sitting in your backyard for more than two weeks is not going to decompose the pile unless you are consistent with turning it. Expert gardeners suggest that turning compost pile once every 3 to 7 days is necessary to get the job done.
You might not be turning it because doing the work with fork or shovel is hectic, times consuming and it does not pay well either. When the tool you are using to turn the compost bin isn’t deep enough to reach the bottom of the bin and not enough steady to cut through the material, you are not going to get attractive results.
The compost pile is not the only thing which needs to be aerated, you should aerate your lawn regularly as well. This process will help in regulating the oxygen, stopping drainage issues and helping the grass to grow faster.
If you know this already and are considering buying a professional compost and grass aerator which not only makes the work easy but also lasts for the long term then you have got a lot of options at hand.
The first step in buying a product is doing your research and evaluating the options.
We have reviewed many aerators from almost all of the top brands available in the UK and here are some worth mentioning.
