Nearly one third of our food ends up in the trash can. There is hope, however, in the form of worms, which naturally convert organic waste into fertilizer. Learn about vermicomposting – nature’s ultimate recycling system, build your own worm bin, have fun, and assist a local social initiative all at the same time!

Class location: Pacific Mission Garden - 1458 S Canal St, Chicago, IL 60607
Date and Time: Wed, December 18 – 10am – 1pm.
Cost: $40.00 - ($20.00 will be directly donated to Pacific Garden Mission and covers the cost of the worms)
Materials List:
Worm Bin: Please bring a Rubbermaid 10 to 14 gallon Roughneck. May be purchased at Home Depot for under $20.00. All other materials and tools will be provided.

In this three-hour class, you will learn about vermicomposting, build your own worm bin, and we will hand harvest worms in the Pacific Garden Mission’s greenhouse. Each participant will take home their bin and 1 pound of worms. (Please note that the worm harvesting will take approximately 1.5 - 2 hours standing at tables so participants will need to be able to stand for most of that time. If you have a physical difficulty, please let the instructor know). There will also be a demonstration on using the worm castings to make an aerated compost tea in a very low-tech system.

Pacific Garden Mission ( is a homeless shelter in the South Loop section of Chicago, Illinois, founded in 1877, by Colonel George Clarke and his wife, Sarah. It has been nicknamed, "The Old Lighthouse." It is the oldest such shelter in Chicago and is the oldest, continuously operating rescue mission in the country.

On an average night, over 500 homeless men, women, and children receive safe, clean and warm shelter at Pacific Garden Mission. During the cold winter months, that number climbs well above 800. In addition to a clean, comfortable bed, Pacific Garden Mission also provides food and clothing, as well as medical and dental care, if needed. Pastors and counselors provide needed spiritual help. Everything is provided free of charge to all who enter "the doors that never close."

Pacific Garden Mission has a greenhouse run by Robert McKinney, a Windy City Harvest graduate. Small fruits and vegetables are grown to supplement their facility’s kitchens. Within the greenhouse is an area dedicated to vermicomposting and outside PGM has a small fruit orchard and outdoor garden beds. We will be harvesting worm castings for use in their gardens and we will also be harvesting worms for use in our individual bins that we will make that day. Perhaps you will also consider taking a pound home as a holiday gift? !

Why vermicompost?
• After digesting the edible components, worms produce nutrient-rich remains in the form of worm castings, or vermicompost, an extremely rich form of compost.
• Worm compost (castings) can be added to indoor plants as well as outdoor plants as a rich form of plant food or can be used as the basis for aerated compost teas to be used in indoor and outdoor plants.
• Vermicomposting reduces the amount of garbage produced and sent to the landfill, because food scraps, dry leaves, and newspaper are used in their bedding.
• Redworms (Eisenia foetida), the type of worm used in worm bins, reproduce rapidly and can be shared with others for starting their own worm bins.
• Worm bins, when maintained properly, produce little or no odor.
• Worm bins are small, compact and perfect for apartment dwellers.
• It is easy to maintain a worm bin than a compost pile, which needs to be turned weekly.
• Worm bins are an easy way to introduce children to composting and caring for the earth.
• Worm bins can be kept indoors during the winter and relocated outdoors during frost-free months, thus extending the composting season to year-round.
• Worms are great pets – they are quiet and you don’t have to walk them!
