What to Look For

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
Using 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!
