Friend Huey was already immensely successful growing garden produce for his wife and twelve kids. He enjoyed reading publications by the Rodale Press that showed him how to achieve success. But he also was an avid reader of publications penned by red wiggler enthusiast Earl B. Shields. Shields promoted raising earthworms outdoors.
Our TakeTimes were tough. Work was hard to come by. We were in a position to devote time to developing our own red wiggler business. At first we were inclined to dub it the ridiculous name, H&V Wormery (for Huey & Vince). Wisely, we changed our mind. We called it the Year-Round Worm Farm. Because we didn’t wish to limit ourselves to seasonal sales, we elected to move operations (including breeding) indoors. We appropriated Huey’s basement.
Red Wiggler Breeding LayoutThe layout was fairly simple. Worms multiply at a prodigious rate. We needed to provide bedding, moisture, food, and appropriate health care. The temperature of most basements is ideal—from the 60s to the 70s.
Many forms of bedding can be used, and a variety of foods can be chosen. We elected to combine peat moss and coffee grounds plus limestone (NOT lime, which burns). The worms love coffee grounds. But we supplemented their diet with dry-ground rabbit food pellets. We would cover the containers of worms with some newspaper sheets, though I would recommend slightly undersized Masonite sheets.
Food and lightly moist bedding were placed in each of the smaller boxes lining the wall, along with a portion of the breeders. After a month, the breeders are removed and the remainder, which included earthworm cocoons, was emptied into the first large box on the floor. The process was repeated, except after that month passed, the boxes were emptied into the second large box. And similarly for the third month. At the end of that time, the worms in the first large box were separated. An appropriate number of the breeders were put into the smaller boxes and the rest were sold. of the worms and the box contents (rich in worm castings “fertilizer”) were sold.
When shipping, we placed the worms in an aerated container with peat moss, a bit of limestone, and a bit of peanut oil for food. If we had put some bait containers in stores for consignment sales, we would have done much the same thing. The primary markets for worms were threefold. 1) To provide worms to other, smaller providers, 2) For organic gardeners, and 3) For fishermen.
The primary health culprit is the Pacific red mite, a tiny, tiny critter that raised havoc in the beds. Choice of an appropriate pest control was difficult, since many of them attack the worms as well! We chose diazinon. Since 2004, many restrictions have been placed upon its use, which almost seems a shame, as it did such a remarkable job for the wigglers.
Juggling the NumbersIt takes some three months to raise mature red wigglers from egg sacs and a mature population of red wigglers doubles approximately monthly. Let’s assume the grower wishes to achieve a relatively modest total population of 1,000,000 worms. Working backward, we get
Month 1: 500,000 worms
Month 2: 250,000 worms
Month 3: 125,000 worms
Month 4: 62,500 worms
Month 5: 31,250 worms
Month 6: 15,625 worms
Month 7: 7,800 worms
Month 8: 3,900 worms
Month 9: 2,000 worms
Month 10: 1,000 worms
Month 11: 500 worms
Month 12: 250 worms
