I just spent 10 minutes tearing up a cardboard box. Now the pieces are soaking in my kitchen sink. In an hour or so, I'll drain the sink, and take the soaked cardboard out to my worm box. My two year old and I both think it is pretty cool that we have worms on our patio to eat up our trash (at least our non fatty food trash and a good bit of paper). If that'd weren't reason enough to be excited about my worm box, those little crawlers also provide rich compost. Woohoo! All this on our tiny patio.
Things I've learned so far:
If you buy a watermelon that tastes kinda yucky, don't put the whole watermelon in your worm box (or at least not all on the same day). This will turn the worm box into a swamp.
You definitely need holes drilled on the bottom of the box. This also helps prevent swamp like conditions.
If the box is smelly, something is wrong. Probably you've overwhelmed the worms with too many fruit scraps.
L loves to "feed the worms." This is the exact kind of pet our lifestyle can handle right now.
