Buyer’s Guide

Because compost aerator is a simple tool, there aren’t many features to put to memory. They just need to be designed well enough to pierce through the compost and introduce air pockets and mix the compost up well, which is crucial to decomposition. The best compost mixer is one that you can use for years to come without succumbing to rust or corrosion so being made from quality material is the number one consideration.

Reasons to buy one

Why should you purchase a compost aerator tool? You could always use tools like shovels or forks but there are reasons as to why the aerator tool is the best. 

  • They are designed to get to the bottom of the compost which is difficult with a fork or spade ensuring that all the moisture and air is present for decomposition.
  • They allow you to work without getting messy. Once you push the tool into the compost you can slowly move it out without splashing any of the liquid compost.
  • Compost mixers with handles allow the user to work without straining their back or shoulders.
  • They are easy to clean and maintain as they have no complex features that require repair.
  • Because they are so easy to use, you can easily manage your compost, therefore, preventing the accumulation of odours.

Plunge or corkscrew

There are various designs of compost aerator tools on the market but the majority of them are categorised under plunge or corkscrew types.

Corkscrew aerator tools are shaped like a corkscrew as the name suggests. One needs to twist the tool into the compost and pull it out to introduce air into the compost and mix the compost. These tools are recommended for light compost mixing meaning that the compost material should not be too heavy to get through.

Plunge aerator tools usually come with blades that are retractable. The blades open wide when the aerator is pulled out to create the air pockets needed. These tools are more well-suited for compost that contains a lot of fibre. Because they mostly feature T- handles, they make it easy to push and pull the tool in and out of the compost without straining your muscles.

Durability

The material used to make the aerator will determine how long you are able to use it. Compost aerator tools sold on the market are made of steel or aluminium. In most cases, these materials have to be given protective coatings so that they are able to handle constant use without bending or rusting. If you have a large compost settle for compost mixer tools whose material is a bit thicker. This is because as you are twisting, pulling and plunging, the material is able to remain firm.

Length

It is important to consider the length of the compost aerator tool so that it is able to get to the bottom of the compost bin. Using a tool that is too short will leave some of the compost material without air, therefore, causing an uneven decomposition. If you are unsure, measure the height of your compost bins and compare it with the product description details of the tool.

Comfort

Some of us suffer from sore muscles, arthritis and other ailments that need some care. Using tools that are designed to keep your hands and muscles comfortable is advisable. Products such as the Darlac Compost Aerator provide comfortable handles that have grip. You can use it for some time without applying too much strain to your body.

Price

Decide how much you can spend before heading to the marketplace otherwise it is easy to get swayed. With compost aerator tools, being the most expensive doesn’t always mean it’s the best tool. You just need to pick one that does the job for you. Like always, it is advisable to check through customer reviews so that you can have an idea of the pros and cons of the tool.

Warranty

If you can get a brand that offers a warranty then run with it. A warranty will allow you to test the strength and functionality of the tool. If any problems arise, the warranty will be your ticket to getting a replacement or refund.


Final Conclusion

We believe that by now you are a compost aerator tool guru and we send you forth to select the best compost aerator tool you can find. Pass this information around and support others in finding the best compost mixer. Remember that mixing compost is a physically demanding job and if you are not strong enough for it, you may want to consider a tumbling compost bin instead, which is easily turned whenever required. Still, you are better off with a compost aerator tool than a fork.
