Willies Worm Farm
first a disclaimer...I was informed by uhhhh..I want to say dickhead,,,,,,,,,,,,but I'll say superior grower/grow legend in his own mind instead,,,,,,,,that this method doesn't work. (Ha!)
All it is are planks and boards layed down in a garden path. I lay them on the sod that's there. There they sit for a year. The worms like the cover and eat and poop out all that sod. Roll over the board and skim the worm turds off the top. Square shovel rocks for that... Wash , rinse, repeat. Hell there are still worms under there eating yesterday .. it's cold!
Ymmv...........but these are basically free turds for the scooping. I netted a true 7 gallons of worm castings and they were promptly dumped where one outdoor plant goes next year. you see at the end.....the boards are back on the sod. Weeds will take over the cleared space and make new sod.
