For the past few months, I’ve only added food to the left-most side of the worm bin in hopes of convincing all the worms to go over and stay on the left side and let me use the castings on the right. I was trying to avoid the time-consuming task of filtering out the worms when I want to use the castings. The plan kinda worked, but there are still lots of worms left on the right side, even though they haven’t had any added food. What I thought was just worm castings has sunk down a good 3 inches, which tells me the worms are still working on it.
Other observations: I had a lot of worms crawl out of the bin this year. I think this was because I overfed them at one point and created a hostile environment. You can see lots of dead worms on the ground.
This bin has worked out very nicely. The worms are safe from critters and haven’t seemed to have any problem surviving the blistering summer heat or the super cold winter.
