With in-ground composting, you can enrich the soil in your garden without bins, piles, or pitchforks. You won't even need red wigglers (the Cadillac of worms). So, what will you need?

Tools You Need for In-Ground Composting

  • Something to dig with
  • A bucket of kitchen waste
  • A minimal amount of time.

Of course, compost holes may not be the right choice for all gardeners all of the time. But, there are certain situations for which they're very well-suited, and certain types of gardeners for whom they're perfect.

Below, you'll find five good reasons to compost in-ground, as well as advice on what to compost. And, you'll get directions for two methods of in-ground composting—the one-hole and the two-hole method.

Reasons to Hole Compost

Here are some good reasons to hole compost.

Small Yard? No Problem.

If your yard is too small to accommodate a compost bin or tumbler, you probably don't have a spot in the sun big enough for a compost pile either. But you do have room for compost holes. The only space they take up is about 12 inches--underground.

Lean Wallet? That's Okay.

On a tight budget? Compost holes are a good alternative to expensive bins and elaborate boxes. The equipment required is minimal: a shovel (or a spade if the ground is soft) and kitchen scraps. And you don't have to add costly composting activators either.

No Time? No Worries.

Hole composting (at its most basic) requires only three steps: digging a hole, dumping kitchen scraps into it, and then refilling the hole with soil. If the ground is soft, it takes five minutes or less. What a great way for busy gardeners to enrich their soil!

Planting Trees? In-Ground Compost First.

Before you buy a new tree or shrub, create a compost hole where you intend to plant it. During the summer or fall, fill it with composting materials and soil, and top it with mulch. By spring planting time, the soil will be friable and rich--perfect for feeding the newest member of your landscape.

Raised Beds? You Can Definitely Dig It.

Compost holes are also a super-easy method for building up the soil in raised beds. Because raised-bed soil is usually soft, holes take little time to dig. And you can in-ground compost all year round, so long as the ground isn't frozen.

What's in Your Compost Pail?

What is in your compost pail is very important.

What to Use

Fill your compost pail with vegetable and fruit trimmings, such as potato and banana peels, apple cores, and the butt-ends of Romaine lettuce and celery. Egg shells, tea leaves, coffee grounds (with filters), peanut shells, and soured milk are also great additions.

Additional common household wastes that can be added to your bucket include wood ashes, shredded newspapers, and recyclable egg cartons. You can even empty your hairbrush and your pet's brush into the bucket. After all, hair contains nitrogen.

What Not to Use

All kitchen scraps aren't compostable. For instance, meat, grease, bones, and cheese shouldn't go into your compost bucket. Not only will they attract animals, but they will also take a long, long time decompose.

Anything that could harbor disease or that contains ingredients harmful to plants should be excluded, such as pet feces, sick houseplants, coal ash, and color newspaper supplements.

pet and human hair

pet feces/used kitty litter

black & white newspaper

color supplements

wood ash

coal ashes/charcoal briquettes

The One-Hole Method

The one-hole method is simple:

  1. Dig a hole eight to 18-inches deep. The hole should be at least eight inches deep so that the soil barrier protects the composting material from pests. And it should be no more than 18 inches so that it won’t leach into the water table.
  2. Dump in one to two quarts of composting material (about one or two inches).
  3. Fill the hole back up with soil.

Want to Speed Up the Process?

Kitchen scraps take one to six months to decompose, depending upon moisture levels in the soil, the temperature, the soil type, and the type of scraps that you bury. If you want to speed up the process, cut kitchen waste into small bits or process it in a blender before dumping it into the hole.

As soon as you bury your scraps, you can plant seeds and small seedlings on top. For large transplants, like trees, wait until the scraps have decomposed.

When you want to prepare the soil for a new tree or shrub, sow seeds, or transplant seedlings, try the one-hole method. It’s also great for gardeners with a pail full of kitchen waste on their hands and little time.

Have time to experiment? Check out the three-part blog at "Real Food & Scandalous Gardening Secrets." It offers step-by-step directions for layering a variety of composting materials.

The Two-Hole Method

The two-hole method is a little more complicated than the two-hole, but not much.

  1. First, dig a hole between the rows in your garden. For the reasons noted above, it should be approximately one-foot deep.
  2. Dump about two quarts of kitchen waste into the hole.
  3. Then, fill it with dirt acquired from digging a second hole beside the first one.
  4. Fill the second hole with kitchen scraps topped off with dirt, either from the first hole or from a third one.
  5. Stop at two holes, or continue until you run out of composting materials. If you don't have enough kitchen waste, you can dump in store-bought compost instead.

The two-hole method is also a good way to improve the soil in a fallow raised bed.

Questions & Answers

Question: Will a compost hole attract gophers?

Answer: Since gophers eat vegetation, they might be attracted to compost holes filled with green matter, at least prior to decomposition. If you have a gopher issue, you could deter them from buried vegetable matter by adding onions and/or castor oil granules into the mix. Gophers dislike the scent of both. You could also plant allium bulbs and/or narcissus bulbs in the covered hole to repel them

Question: How far apart should the compost holes be?

Answer: You don't have to worry about the distance between compost holes. In fact, instead of a hole, you could dig a trench the same depth as you would a hole and fill it in the same manner as a compost hole. This is called trench composting. I did this recently for new flowerbeds, digging the trenches and filling them with composted manure.

Question: Can I put horse manure in my compost hole?

Answer: Of course! Just be sure the horses have been munching on herbicide-free grass. Here's a link about this problem from the MD Extension:

Question: Will any problem arise in mud with stones when attempting to enrich the soil?

Answer: That would probably depend on how muddy and rocky the area is. I think it would be difficult to dig through a highly rocky site; likewise, digging in a swamp-like area might result in a muddy hole. You can but try!

Awesome! Yes, it is really cool to know others are recycling, reusing and re-purposing. We're in it together! Thanks for your comment. J

I've been doing this at my summer cottage by digging shallow holes in the woods for my vegetable and fruit scraps. I take them out daily so I won't get fruit flies inside. Glad to know that others are doing this too.

Hey Jill this is Shiva...... How did you like the story?..... When I was writing it I had tears in my eyes.... The story reminds of someone who is looking in the mirror and their own image turns around and walked away... The Bible says that man was created in God's own image.....

ed on June 11, 2018:

The last part of the story is...... All the people had to do is what the messenger said. Being said from the spirit of God. To help create the new world order. Under God...

But the messenger would need the permission from the people all over the world. For it to happen. After reading this, listen to. One republic : apologize. The song...

ed on June 11, 2018:

So in the man's moment in the pit of despair and tears, God gave the man power, and the man took the Earth and all the people in it , placed them in the palm of his hands and crushed them into dust from which they came. And the Earth and the people were placed into the kingdom of darkness, never to see the light of god again. As for the man, he was sent to the kingdom of darkness and never to come back out again. Then God sat on top of his stone crying and crying and crying, which seemed like forever. Then God forgot about the Earth and the people; so he got up and walked away to make his next creation. But in the back of his mind he knew that everytime he would create, whatever he creYed would not want him too... So as a form of love that was his his spirit he kept on moving forward creating, because that is what he loved to do. Hoping that one day one of his creations would come looking for him as his own form of love.

From the messenger of God. AKA Eddie aka Shiva

To do was make the entire world and all the people rich and overflowing with mansions as far as the eyes could see. For preparations for the coming of God into his own creation. But when the man came into the world the people would not have him, they would not help him, they would not accept him.

Yes, that's trench composting. I add fertilizer on top of the compost then put the dug-out dirt on top. I did that today-- 10 x 3 feet. What a job! But well worth it. Thanks for sharing, Ed. All the best, Jill

ed on May 03, 2018:

Digging out your given area garden a foot deep. Take all the dirt out. Put dirt to the side. Fill the entire area with compost....... Deep.... Then take the left over ground dirt and cover all the compost area. So the sun does not dry out the compost..... Do not step in your garden.... You will cut off oxygen supply to the roots... Plant your plants all along the outside area.. In the compost... Let the rain do the rest.... Yours truly.... Shiva

Hi Dalia. Compost holes may not be the best way for you to go if you have no space, although I guess you could bury scraps in pots and leave them out in the weather on your deck to decompose then, the next season, add plants. Have you considered composting in a black plastic bag? Again, leave the bag in the sun, turning it every so often. How quickly you create composted soil depends on how hot it gets where you live. You could also try worm composting, which can be done indoors.

dalia hosnii on July 22, 2017:

thanks it's very helpful , I was looking a method to use my kitchen scraps , but I don't have a garden , I plant a few plants in my balcony , so , can I do it in a big bucket ? , should I wet the soil , say every week ? .. If I grind the scraps , and the weather is hot , It will take how long to be ready ? .. and can I add more scraps and mix it and cover again ?.. too much questions , but I'll be very grateful for your help ?

Hi kalinin1158! Thanks for dropping by. Hopefully you can at least add some fresh soil to the area around your patio even though it's shallow. All the best, Jill

Lana Adler from California on January 13, 2016:

I like this method but the soil depth on my patio is so shallow, I'm not sure it'll be deep enough for the compost hole. . . But I love the idea! Thanks for the tips.

Hi rogolo! I bet your soil has become much a lot fertile over time. A post-hole digger would truly expedite things-- if I could pick ours up! lol. Thanks a lot for stopping by. It was great to hear from you. --Jill

rogolo on June 04, 2014:

I do this with a post hole digger. After I dig a hole and put the scraps in, I crush the scraps using the digger with the blades closed. Then I push the dirt in and tamp it with the digger and finally cover it over. Usually, I have mulch where I dig, so the mulch gets mixed in too.

Jill Spencer (author) from United States on March 09, 2014:

Hi Tom! Thanks for stopping by. Yes, I too sometimes slice through a worm when digging holes. We have a lot of them in our garden, for which I'm very thankful. I just learned at an MG class the other night that earthworms are not indigenous to North America. They were brought, caught up in roots balls, with settlers. I had no idea! Take care, Jill
