I have a happy worm bin that takes care of most of my composting needs. I use the castings around my garden, mostly when I’m planting something new, but I also feed my established plants with it when I can.
But! I’ve also been thinking it’d be great to deliver castings right into the ground, and would love to use semi-buried containers in the beds to compost right there. There are plenty of native composting worms in my location.
I have a bunch of small (1-1.5 liter ish?) buckets with lids that I’d love to repurpose for this. I was thinking I’d make a bunch of holes in the body and lid of the buckets, and bury them up to the rim. Then fill with some bedding and some scraps, and inoculate with come castings and some worms. And just feed whenever there’s space, hoping the castings spread a bit into the ground, or otherwise dig it up when it’s full of castings and bury it in a new spot.
My main concern is that the buckets would be too small. The reason I’m aiming for this size is honestly because I want to use these containers for something useful instead of tossing them out. I’d love any suggestions and to hear about your experiences with in-ground composting!
You’re right about the blog posts, I used to say the same thing on reddit. Almost everybody that writes one is freshly into it, it’s hard to find someone with 20 years experience writing something online.
I tried worm towers, I tried trenching beside planting lines, I was a moderator on the PRI forum (Permaculture Research Institute) and was exposed to many others doing it (forums were great at about 2005 onwards, people like Darren Doherty et al were regularly posting). The trenching worked well but only because I was urban, there was minimal animal pressure (no rats even). There is no chance I could do anything in-garden now without it being Fort Knox because the pressure is freakishly high, even all types of gardening is difficult. I prefer methods of composting that don’t require labour inputs so tower, trench, worm farm are the best for me. I used to do proper piles at the right ratio but that was full on work gathering ingredients. I use pyrolysis to clean up everything else and chop/drop.
Once I decided to use the worms to process char and my experiments with ratios were finished, I just stopped all that, moved fulltime into the bathtub and started cycling more in there. I found an old blender and could increase processing speed some too. And then years passed and I’m still doing it as it handles out family output just fine as is.
