Where to Find Free Compost: 4 Unlikely Places to Get Black Gold for Your Garden This Spring

Very few pastimes are completely free, and anyone who has gardened for a few seasons knows how expensive a veggie patch, home orchard, or lovely landscape can be. Not that it deters us! But it does make us eager to find free sources for the items we need, like compost.

Clearly, nutrient-rich soil is a garden necessity, and the garden store offers big and small bags of it…for a price. Compost can turn regular garden soil into super soil. It’s easy to find commercially. However, compost can cost a pretty penny. You can make your own compost at home, too. But if this is your first year gardening and you haven’t delved into the world of compost yet or you simply don’t have room for a compost pile, then you might be looking for places to find free compost.

Lucky for you, there are a few different sources for free compost that will help turn your garden from okay to amazing. However, there are a couple issues to be aware of when sourcing compost for free that will protect both you and your garden. Read on for the scoop.

Benefits of Compost

Compost sometimes seems like magic. You add it to the soil and it pushes your plants to grow bigger and better than you’ve ever seen. It’s pretty amazing because it is made of unwanted scraps, but the compost enriches your soil with this recycled organic matter.

Compost is a mixture of food scraps and yard waste that, when decomposed, becomes an exceptional fertilizer. It improves the nutrient content of the soil and also builds up the soil texture so that it drains better, but still holds moisture.

Free Compost From Your Backyard

Many of us get free compost from our own backyards. It is easy to create a compost pile in a distant corner of the property that gets some sun. You simply clear the area, build “walls” around it, if you wish, then layer brown material (like dry leaves or straw) and green material (fruit and vegetable peelings, coffee grounds, eggshells).

Keep adding brown and green compost material to the pile throughout the year. Setting up a small kitchen compost container makes it easier to carry out scraps. Water your pile every week or so and turn your compost occasionally. Over time, the material will decompose into a rich, dark brown compost that’s ready for your garden.

Composting Essentials

Where to Get Free Compost

If you don’t have space for a compost bin or don’t have the time or ability to tend to one, there are a number of other places where you can get free compost.

1. Your City

Many cities collect organic matter at the same time they collect garbage. Here in San Francisco, each residential household has one blue bin for garbage that can be recycled, one brown bin for garbage, and one green bin for things you can compost. In exchange, they offer free compost to residents.

That is, as a San Francisco resident, you can get high-quality, organic compost made from the materials you put in your green bins. The compost is free at giveaway events throughout the year. These happen every month and compost and free mulch are always available.

Check with your city to see whether it has a similar program. You might call the city government, mayor’s office, or simply do a quick Internet search for "Does [your city name] offer its residents free compost?"

2. Community Gardens & Urban Farms

In some cities, community gardens or urban farms provide gardeners with a good example of using sustainable gardening practices. This often includes composting on the site, generating compost from kitchen scraps and yard waste just like you can compost at home.

They may give away extra compost to residents or you may have to put in some time volunteering at your local community garden to qualify, but it costs nothing to ask.

3. Local Universities & Colleges

Another great place to try for free compost is your local college or university. Many schools have horticulture or agriculture programs that produce free compost by collecting food waste and yard trimmings from campus.

Sometimes they offer free compost to the community. Contact your local university, college, or extension service (usually connected to a university) to ask about their program and how you can access it.

4. Online

What’s your favorite website to get free stuff? Everybody has one. Here in San Francisco, there are several popular neighborhood giveaway sites that don’t allow any sales. Mine is called “Buy Nothing Outer Richmond,” but one exists for just about every neighborhood in the country.

Lots of people love the “free” sections of Facebook Marketplace, Craigslist, the Nextdoor app, Freecycle, or OfferUp as well. Just join the site, then search for free compost. This is a great way to use technology to grow a better garden.

Be Careful With Free Compost

Everyone knows the old adage, "You get what you pay for." That doesn’t mean you should reject free items, but it means you should be cautious. This is also true of free compost. Free compost sources may not all provide the best quality compost.

What could possibly be wrong with compost? Well, actually a lot. The compost might include contaminants, which can impede plant growth or soil health. It’s easy to accidentally include weed seeds in compost. And compost piles can attract unwanted pests, including flies, termites, and beetles.

Finally, compost piles can be breeding grounds for dangerous pathogens, including fungal infections like aspergillosis, farmer’s lung, histoplasmosis, Legionnaire’s disease, and tetanus.

It’s a good idea to wear gloves, appropriate footwear, and even a mask when using compost from an unknown source. Or better yet, make your own compost at home. This is a fantastic way to turn kitchen scraps and yard waste into garden gold.
