Have you ever heard of a compost accelerator?

It sounds like a device, but it’s actually a little pack of bacteria and fungi. Manufacturers specifically make them to help your compost decompose faster than ever. And if you’re a compost enthusiast, then you already know how important it is to get your compost to decompose as quickly as possible.

As a side note, compost accelerators also go by the names of compost activators or compost starters. So, if you see those names, know that they’re all referring to the same thing.

Of course, it would be easy if compost accelerators were all the same in terms of quality. Unfortunately, just like any product, they’re not.

So, it’s essential to know which ones are the best.

With that in mind, here are the 6 best compost accelerators we recommend!

1 – Dr. Earth 727 Compost Starter

Key Features

  • 100% organic and natural
  • Turns organic waste into humus
  • People and pet-safe
  • Alfalfa and seaweed formula
  • All-purpose composter
  • Recycle waste from the kitchen and yard

Dr. Earth 727 Compost Starter is one of the best in the market.

It’s made with a special blend of alfalfa meal and seaweed extract, and full of gentle soil microbes that will make decomposition go faster than ever. 

It’s organic and all-natural, making it perfect for the conscientious nature lower!

What’s more, it’s both people and pet-safe.

In a nutshell, it’s the ideal, all-natural, non-toxic, compost accelerator!

2 – GreenPiG Compost Accelerator

GreenPiG’s compost accelerator is second on our list for several reasons.

One of the most important to us is the fact that their compost accelerator uses bacteria you’ll already find in your soil. Using their compost accelerator means you’re adding more to speed up what the bacteria already there are doing.

If that’s not enough to get you interested, it’s also worth knowing that this starts working within 30 days. They also help control compost odors

Plus, purchasing one bag gets you 12 water-soluble packets instead of one. Having the individual packets is also nice since they allow you to be more precise in using your compost accelerator. For reference, each one treats 9 cubic feet (0.25 cubic meters).

You can have some peace of mind as well, knowing GreenPig has been in business since 1996.

To use GreenPiG’s compost accelerator, take the following steps:

  • 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

3 – Dr. Connie’s Natural Compost Accelerator

Key Features

  • Compost-accelerator  
  • Super-concentrated
  • Creates a nutrient-rich compost
  • Helps fight compost odor
  • Works with or without a compost bin (super-effective)
  • Non-toxic (pet and person-friendly)

Dr. Connie’s Natural Compost Accelerator works through the use of a refined formula, which increases the heat and O2 in the composter.

This is done with the use of certain bacteria and fungi, which specialize in composting.

Not only is this brand super-concentrated, but it also fights against any unpleasant compost odor!

It works with or without a compost bin (although a bin will make it go faster, of course).

Finally, Dr. Connie’s Natural Compost Accelerator claims to be 100x more potent than the leading brand – wow!

What to Look For In Compost Accelerators

To get you started, here are a few things that, when it comes to finding the best compost accelerators, you’ll want to consider! 


The best compost accelerators are those that are all-natural.

Keep an eye out for any mentions of chemicals, as these are not ideal.

Fortunately, most accelerators are, by nature, all-natural.

They’re made up of a combination of bacteria that speed biological activity along.

This means that, with a quality compost accelerator, you’ll have compost faster than ever!


The best compost accelerators should take no more than 1 month for the results you’re looking for.

In this time, they will cause the necessary biological activity (speeding along with the natural processes) to create nutrient-rich compost (which will then make your garden healthier than ever).

Best Homemade Compost Accelerators

If a brand appeals to you overall but takes a bit longer, it’s also up to personal preference, of course.

But you can definitely find certain compost accelerators – such as those above – that work fast, possibly faster than ever!


Does it create compost the way it should?

This is something you’ll have to check the reviews for!

All of the organic accelerators on this list do.

They are top-quality, and any of them will do the trick!

An Easy Distributor

This is less important than some factors, but may also matter.

Does it have an easy distributor?

Some bags have their own easy-close spout. Others come in packets.

While neither of these is strictly necessary, especially if the brand is good, it will still make your task a bit easier!

Final Thoughts

So, there you have it: some of the best compost accelerators out there, and how to find the ideal one yourself.

All of these accelerators will work in roughly a month, giving you quick access to nutrient-rich compost, and a garden that’s healthier and more beautiful than ever!
