Can You Compost Avocado Pits? (Methods, Tips & Uses)

Would you believe me if I told you that avocados could turn into a healthy and nutritious soil additive for your beautiful gardens? The avocado flesh and peel can be composted as they are soft and can decompose; the big deal is the fruit’s stone, the avocado seed. So, let’s find out, can you compost avocado pits?

Avocado pits are compostable and provide carbon-rich nutrients to the compost as ‘brown materials.’ But you may need to crush them before adding them to your compost pile for faster decomposition, as avocado seeds are stiff and solid and may take longer to break down.

Are Avocado Seeds Good for Compost?

Avocado seeds are a good and healthy composting ingredient because they act as a ‘brown’ material, supplying carbon and energy to the microbes involved in the decomposition process.

Additionally, avocado skin and meat can also be composted as green, nitrogen-rich organic materials so you can chop and toss them in with other compostable food scraps.

How to Compost Avocado Seeds:

Now that you know avocado pits can be composted, and are actually good for fertilizers, let’s understand how to do it.

Well. If you simply want to add avocado pits to an already established and healthy compost pile, then simply crush and bury them in the center of the compost heap, and you’re done.

However, follow these steps if you’ve just begun a new pile.

1. Crush the Avocado Pits:

An avocado seed, as you can see, is very rigid. If you are in a hurry and toss it in a compost pile as it is, it may sit in a corner for months without being broken down at all.

The best way to compost avocado pits is to break them into tiny pieces before adding them to the compost bin. You can do it at home in two simple ways:

You can either grind the avocado seed in a powerful blender or smash it with a hammer from your garage.

2. Mix With Other Brown Materials:

Your crushed avocado pits are now ready to mix with the other brown materials, including yard waste, hay, woodchips, leaves, newspapers, sawdust, chipped tree branches, straws, shredded cardboards, and even paper towels and paper bag shredding.

3. Prepare the Bed:

If you’re setting up a new compost pile, you need to bed it with a thick layer of brown materials. This will prevent any unpleasant odors and spills in your garden.

The brown materials are carbon-rich substances that supply food for all microorganisms working their way through the compost pile to break down the materials you add. Furthermore, these materials help to keep the pile aerated.

4. Add Green Materials:

Now add the second layer of green materials, including your kitchen scraps like coffee grounds, fruit and vegetable skins, eggshells, etc. Ensure you don’t use oily food waste, meat, or bones, as these materials are not compostable in a regular compost heap.

You can also include the meat and skins of an unused or old avocado in your compost pile.

Food scraps and greens are essential for composting as they provide nitrogen and heat for microorganisms to reproduce and grow.

5. Repeat the Process:

Following the green layer, it is now time for brown materials. Rep this cycle until you’ve sorted all of the waste for the week. To provide insulation for the pile, make sure the top layer is made of brown materials.

A healthy compost pile necessitates a good balance of greens and browns. Generally, a ratio of 3 parts browns to 1-part greens is ideal for composting, but you can adjust this depending on needs.

If your compost pile is leaking or stinking, it is time to add more brown matter to it. And, if the pile becomes slow and cold, you may need to add more greens to it.

6. Maintain the Pile/Bin:

Turn or mix your compost heap once or twice a week to allow air and heat to enter and boost the breakdown process. Keep an eye on it regularly to see what it needs and provide it. If you add new material after a week or so, mix it in evenly throughout the pile.

Can You Compost Avocado Pits In A Worm Farm Or Bin?

Crushed avocado pits can be mixed with other brown or carbon-rich materials to make bedding for a worm bin or a large worm farm. This bedding makes for a stable food source for the worms and other microorganisms engaged in vermicomposting.

You can also put the avocado peel in your worm bin, and the worms will decompose it, giving you good, rich organic fertilizer for your plants. Although avocado flesh is an oily substance, worms will also eat it if you put it there.

How Long Does It Take For Avocado Pits To Decompose?

Avocado pits can take six to twelve months to decompose in a compost pile. You can break down the avocado seeds before adding them to the compost bin if you want to harvest the finished compost soon.

Many factors affect decomposition time, including pile temperature, aeration, moisture, material ratio, ingredient surface area, etc. Maintain everything, and you’ll have good compost in a few months.

Benefits of Composting Avocado Seeds:

If you’re wondering why you should compost avocado seeds, here’s what you should know:

  • Avocado pits add carbon nutrients to your compost bin, which will provide food and energy to the microbes for a long time.
  • It reduces the amount of food waste disposed of in landfills.
  • If you do not have enough yard waste to put in a compost heap, avocado seeds are a suitable substitute. 

Additional Tips for Composting Avocado Fruit Pits:

The following tips will help you in composting avocados in a healthier way:

  • Do not put the avocado fruit seeds on top of the pile.
  • Bury the pits in the center of the compost bin because it is the warmest spot and can speed up the decomposition process.
  • Don’t forget to crush the avocado seeds before adding them to the pile.
  • Soak the avocado seed for a few minutes before composting to soften it.
  • Always add the seeds with other soft organic matter in the compost pile. Adding them alone may or may not attract microorganisms for feeding, resulting in a slower breakdown.
