What do compost worms eat?
Compost worms eat organic waste and, together with microorganisms, break it down into valuable worm humus. Anyone running a worm farm or compost bin quickly asks themselves: What exactly do compost worms eat?
In principle, compost worms love soft, moist, and plant-based materials. This includes much of the kitchen waste generated daily in households.
Suitable food for compost worms
Compost worms eat, for example:
- Fruit and vegetable scraps
- Lettuce leaves
- Potato peels
- Coffee grounds including filter
- Tea leaves and tea bags without plastic
- Crushed eggshells
- Paper and cardboard in small quantities
- Wilted plant remains
It is important that the food is given in small quantities and distributed well. This keeps the system balanced and makes it easier for the worms to process the material.
What compost worms don't like
Some substances are less suitable for compost worms or should be given very sparingly:
- Meat and fish
- Dairy products
- Heavily spiced foods
- Large amounts of citrus fruits
- Oily or very salty food scraps
- Heavily molded waste
Too much unsuitable material can lead to odors, acidification, or an imbalance in the worm farm.
Tips for feeding
Compost worms feed best when the conditions are right:
- Feed regularly, but not too much
- Cut food as small as possible
- Ensure sufficient moisture
- Supplement with dry materials like cardboard or paper
- Always adapt feeding to the worms' pace
With the right food, compost worms remain active and multiply particularly well under good conditions.
