One of the most enjoyable times in our flagship Lab was harvesting day. I know what you’re thinking “Duh, Tim. Kids like to eat!” but I’m not talking about produce harvesting. I am referring to the days when we would harvest worm castings.
See, there is something remarkable that happens with worms. The kids essentially adopt them as part of the team. They talk to them, pick them up and hold them gently. The worms become a focal point.
So when I would announce that we would be harvesting worm poo the crowd would go nuts. They would run to our three bins and fight for position. But we created our own problem. Prolific worm bins lead to more worms and more castings. Eventually, we had more than we could use at that time.
Solve the problem, well, before it’s a problem. Create a plan to store castings for future use. You’ll need a vessel to store them in and the proper environment. What conditions would that require? What is the shelf life of cured worm castings? Will they require any maintenance over time?
