Growing Red Wiggler Worms


Raising red wiggler worms is a good way to both create worm casings and compost for your garden and to create populations of worms for sale to others. Red wiggler worms are good for gardens and are also used as a fish bait. Raising worms doesn't require much time or effort. A few worm bins don't take up a lot of space. The red worms will eat waste vegetable and organic products from your kitchen.

Step 1

Drill about 20 eighth-inch holes on the sides, top and bottom of one of the containers. These holes will allow air to flow through the worm production container.

Step 2

Glue enough window screen on the inside of the drilled container to cover the holes and prevent the worms from escaping.

Step 3

Place some bricks in the bottom of the undrilled bin and slip the drilled bin inside. Because the two bins are the same size, the bricks will raise the bin with holes several inches above the bottom of the undrilled bin. Because one bin is higher, the slanted sides will allow air flow between the two bins. You won't need the lid for the outer bin, only the lid with holes for the inner bin.

Step 4

Place the bin in a location that will always be between 40 degrees F and 90 degrees F. Worms don't like overly warm or cold temperatures.

Step 5

Shred some scrap paper to between a half inch and an inch long and wide. Moisten the paper, but don't make it dripping wet. Newspapers, cardboard, old computer printouts are all good sources of scrap paper. If you have a paper shredder, shredded documents and junk mail are good worm bedding.

Step 6

Add the moist paper and about a gallon of garden soil to the bin with holes. The soil is important for worm digestion.

Step 7

Add two pounds of worms for each pound of vegetative waste produced in your household.

Step 8

Continue feeding your worms. The worm composted waste and worm casings are very good for your garden. After the worms have reproduced to the point that you have about one and a half times your original worm population, make another worm bin and split the population. You should have enough worms for a second bin after 30 to 60 days.

Step 9

Harvest your worms every 30 to 45 days to ensure optimal worm production. You can sell your harvested worms to gardeners, other worm farmers, or people who like fishing. Red wiggler worms make good fish bait.
