"Tree" Boosts Worm Production
 ✖  |
Paul Coleman has gone vertical with his worm production. After starting out growing worms in plywood boxes, he gradually expanded to 2,000 sq. ft. of outside concrete beds (FARM SHOW Vol. 26, No. 5). He still uses the concrete beds for seasonal worm and casting production. However, a new worm tree system inside his greenhouse is showing promise.
"I hang 10 split 55-gal. drums on wood frames," says Coleman. "Each drum holds 10 to 15 lbs. of worms so one tree will produce up to 150 lbs. of worms in a 4 by 4-ft. area."
Each tree consists of a 4 by 4-in. upright with two 2 by 4-in. crosspieces at each level, supporting two barrel halves. Each level is at right angles to the previous level for easy access. The uprights are secured at their tops to the greenhouse frame.
With 20 trees in one end of his 28 by 100-ft., plastic covered greenhouse, Coleman keeps around 3,000 lbs. of worms busy making castings year round. Two wood stoves keep the worms warm in the winter. In the summer, an evaporative cooler keeps them cool.
Coleman also uses the greenhouse for starting seedlings for his intensive market garden. However, the worm castings are his primary product. That's a big switch from earlier years when worm sales were his main product and he couldn't give away the castings. In fact, he used more than 7 tons of castings as fill when he built his greenhouse. Now he can't produce enough castings to meet market demand.
"Everybody is back into gardening, and they want to do it with worm castings instead of chemical and petroleum based fertilizers," he says.
To feed his worms, Coleman has developed a ration based on cotton gin trash, corn, wheat and oats run through a hammer mill.
Coleman harvests castings from his worm trees and beds at the rate of 1,000 to 2,000 lbs. per week, depending on the season. He bags them for sale through retail outlets, the local farmer's market and from his farm.
"In the spring, I have people waiting for the castings to fall from my harvester," he says.
Coleman does still sell worms, especially to gardeners who want to produce their own castings. He sells Can-O-Worms, a home vermicomposting unit that comes with two pounds of worms. The multi-layer, flow-through method is designed for home use.
"I keep two of them in my greenhouse and feed them plant clippings and kitchen scraps," says Coleman. "More and more people are keeping worm bins at home."
One reason may be the price. While he sells his castings for 50 cents per lb., Coleman says he has seen others charging from $1 to $2 per lb.
Coleman also sells worms to large-scale composting facilities.
"Some outfits have 1,000 to 5,000 lbs. of worms, though others are as small as 50 lbs. or less," reports Coleman. "I still have people asking for 1,000 lbs. of worms, but I advise them to start small and get good at castings production. As sales increase, try to stay one step ahead of demand."
