Pigeon poo is free.
I’m always on the lookout for free stuff. My search for fertilizer lead me to a local bridge that was home to hundreds of pigeons.
I thought ‘where there’s pigeons there must be pigeon poo’ and there was. Tons of it, all nice and dry, ready for the taking.
I dug up about 10 kilos of it and took it home where I put it into a plastic bin and covered it in water. There it will sit for month or so to rot down before I use it on the plants.
