Anybody who has a composting bin or compost pile at their house knows that old apple cores, banana peels, and potato skins can be composted. The list of compostable items doesn’t stop there, in fact, it barely scratches the surface.

Did you know that you can compost an old teabag? Old spices? Grass clippings? How about sticky notes? Yes, each of those items can be composted!

There are many compostable items, and this list will get you started with the first ninety-nine. Composting at home is a very effective method to reduce the amount of waste you contribute to the landfill.

If you are composting for an organic garden, use organic starting materials. Some of the items below I would not recommend for organic gardens. For clarity, I will specify those items below.
