Zoo Doo compost is a dark, rich humus, ideal for use as a soil amendment to be mixed into raised beds or used as a top dressing on gardens or potted plants. In this way, the nutrients in Zoo Doo are made available to plants while also providing the benefits of water retention, aeration, and improving soil texture.

Our compost isn’t the only way to get these amazing soil benefits; consider composting at home! Visit the Tilth Alliance or call the Garden Hotline at 206.633.0224 for more home-composting information.

 

 

Worm Doo

Dr. Doo’s private reserve, usually reserved just for the zoo’s greenhouse

Worm Doo is worm castings made from Woodland Park Zoo’s Bedspread compost and organic materials making it a “twice-pooped” commodity! It is an exceptionally rich and fertile soil amendment recommended for seedlings, potted plants or in the garden. Worm Doo has all of the microbes that make Zoo Doo a huge success plus the added benefits of worm castings, like making nutrients more readily available to plants. Look for pint-sized containers in the ZooStores!

Yard Waste

To assist the composting process, the natural decomposers—including microbes and earthworms—need to be fed and cared for.

A properly balanced diet for composting is a thorough mix of fresh (green) and dried (brown) plants—such as fresh grass clippings and old leaves. The more compost material that is chopped or shredded, the faster it will decompose. Gather and mix the shredded materials together in a pile so that about two thirds is brown and one third is green.

• Add just enough water while building the pile to ensure it stays about as damp as a wrung-out sponge.
• The compost pile should be large enough to hold the heat; about three to four feet on a side is ideal. This size insulates but still allows sufficient oxygen throughout.
• Turn the pile occasionally to encourage air flow and to add water as needed to maintain dampness.
• Given a little time (as little as four to five weeks), you too can create rich, crumbly compost in your own backyard!

 

Kitchen Waste/Food Scraps

Although food scraps are organic materials, do not include them in an open compost pile. Left in the open, they tend to attract scavenger animals such as squirrels, rats or flies. Vegetable kitchen wastes are best handled in one or more of the following ways:

Worm Bin (aka Vermicomposting)

Rather than bury the wastes you can also establish a worm bin using compost or manure worms. In this system, set up a container (commonly a box about 3'x2'x1'), mix in shredded newspaper or dried leaves, a little water, food scraps and worms, cover with a top layer of newspaper or leaves, and close the lid. The worms will do the rest.

The simplest method to manage a worm bin is to add food scraps in one half of the bin for about three weeks. Then start working in the other half, again starting with layers of paper or leaves, food and worms. The worms still in the far end will finish their supply and move into the fresher foods leaving their castings behind. These castings can be harvested and used as fine compost.
