Things You'll Need
- Microworm starter culture
- Plain, unsalted oatmeal
- Empty margarine tub with lid
- Yeast
- Eyedropper
Instructions
Purchase a microworm starter culture from a garden center or aquarium supply store.
Prepare a single serving of plain oatmeal according to the directions on the oatmeal's container or packaging. Add slightly more oatmeal than called for, to make the mixture thicker.
Fill a margarine tub ½ inch deep with the oatmeal and allow it to cool.
Smear microworms from the starter culture on the surface of the oatmeal. (Microworms can only breathe on the oatmeal's surface.)
Sprinkle a pinch of yeast over the microworms.
Cover the margarine tub with a lid that has 10 holes poked in it for ventilation. Store the culture in a well-lit room at a temperature between 68 and 85 degrees Fahrenheit.
Harvest your microworms after a week: scrape the worms off the side of the margarine tub and add them to water. Water your plants with the mixture, or use an eyedropper to feed the worms to fish singly.
