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!
The technique used to be called ‘worm towers’. See if you can find a blog or post that is about the same size as you’re suggesting.
Personally, I wouldn’t put plastic out in the garden anymore. I found some stainless steel colanders, a pencil holder from IKEA in charity shops etc, and tried that. Works ok. Maybe masonry bits through terracotta or concrete pots would be good.
To add to this, don’t add in any worms. Let the local worms find your tower. You don’t want to accidentally be adding non native species to your soil if you can avoid it.
Old stainless flu pipes with holes would work well.
Thanks, yeah that’s generally good advice. I live in a location where both red wrigglers and european nightcrawlers are native, and I’m using both of those in my worm bin, so wouldn’t be introducing anything new. But always good to advise caution.
Living in an island nation I’m very biosecurity concious haha
That’s a good idea with the flue.
You can find them at recycle centres and the dump fairly often. They’re good for all sorts
