Now these might not be the prettiest of compost bins, but they do the job well. They were made out of bits of an old fence, and no, I didn't have a plan, they just evolved. They were built to replace a temporary compost heap we made when I first moved in. A local grass snake loved that heap, but I didn't love him. He caused me to shake every time I went near it, and don shoulder length aquatic gloves (for some reason they made me feel safer!). He's left now, but last weekend I spied a baby rat leaving these bins at high speed. I've done a lot of prodding and I don't think he's returned or left any friends in there - only time will tell I guess. No-one told me compost could be this stressful!
