Food for Worm Composting


Worm composting is an excellent way to recycle kitchen waste, while creating soil for houseplants and outside gardening. When only organic materials are used, the resulting compost will help to produce nutritious food plants and beautiful decorative plants. Feeding the worms is easy, and the composting will be successful if the proper items are added to the worm bin.


Fruits and vegetables are great foods to feed to worms. Grains will work, including cereals. Used coffee grounds and tea bags are also beneficial, as are egg shells, herb stems, and other plant parts.


If the bin materials seem too dry, you can add cooled water from teas or coffees. Cooled vegetable and pasta water can be used as well.

Other Add-Ins

It is important to add dry materials to the bin. Shredded newspaper, burlap and cardboard are great for this purpose. Sawdust and other bedding materials, such as seaweed and dried leaves, can also be used. These items help the worms to create compost as well.

Size of Food

Small is better. Chop food items into small pieces so the compost process moves faster. A blender can be used to process food scraps before adding them to the bin.


Worms need a gritty substance in order to process the food that they eat. Adding some sand, crushed shells or ground egg shells will aid in this process. Add the substance to the bin once a month or so.
