When my children were younger I wanted to share the cycle of life with them in a real way. I wanted them to be able to see, feel, experience how the circle of life really works. I purchased some worms, (red wigglers), and purchase a box that would allow earthworms to procreate, as well as eat all the garbage that we generated. We would put our shredded papers in the box, coffee grounds, and the filter, apple cores, banana peels, and various other food in our worm box. We had our worm box outside. I have read that some people keep their box in the home. NO!
When my son was 18 months old, he would take all the daily refuse for the worms to the box. The box did not smell bad, since they eat the bacteria that generates the odor from the food. What does smell is the poo from the worms. Every couple of months we would have to clean out the box, and that wasn’t a fun job. We would separate what was the “black gold” from the garbage, and save the worms. We would then have another generation of worms, and we add the black gold into our garden. We grew some of the biggest pumkins on the block, and then when we were done with Halloween, the worms had their favorite food. Honestly, after having these creatures in our life all these years, I can tell you with confidence that they love mellons, pumkins, etc.
This is the newest edition, it has layers, after a few months, we take it apart and sort out the gold, and start all ove with new food. This system ensures nothing goes to waste. We dont like waste doing nothing, we want to make the most of it.
