It sounds like a product, but it’s really just a small pack of bacteria and fungi. The manufacturers make them specifically to help your compost break down faster than ever.
If you’re a existing composter, then you know that you need to get your compost broken down as fast as possible.
On a side note, compost accelerators are also referred to as compost activators or compost starters. So unless all of those names are confusing to you, they all denote the same thing.
Of course, it would be nice if they were all equal in quality as compost accelerators, but like any product, they are not.
So it’s good to know which ones are the best.
With that being said, let’s take a look at the 6 best compost accelerators!

2. GreenPiG Compost Accelerator

GreenPiG’s compost accelerator comes in at number two on our list for a number of reasons.
One of the biggest reasons is that it uses bacteria already in your soil. When you use their compost accelerator, you are adding more bacteria to help speed up what the bacteria already in your soil are doing.
And if that is not enough to get you excited, it is good to know that it starts working in 30 days. It also helps to control compost odors.
In addition, when you buy one bag you get 12 water soluble packets instead of one. The individual packets are also nice, since you are able to be more precise in your use of the compost accelerator. For reference, each one treats 9 cubic feet (0.25 cubic meters).
You can also have peace of mind knowing GreenPiG has been operating since 1996.
To use GreenPiG’s compost accelerator, do the following:
- Wet the area you’re applying it to
- Put the packet into 1-2 gallons of water
- Let the packet dissolve
- Pour the packet-dissolved solution over the area
- Keep the pile wet and reapply every week
