For the past few months I have been struggling to get compost out of the door at the bottom of my plastic, Lambeth Council supplied, compost bin. It is baseless, physically not metaphorically.

Something tough was hindering the compost falling down. I ignored it to begin with and tried just forcing things down from the top with not much success. Whatever the blockage was, it was so strong that the only thing I could imagine it could be was bamboo.

Last year I had dug up and removed a patch of bamboo around the “Family” sculpture. Despite supposedly being a non-invasive bamboo, it had escaped from the pots and cement I had planted it in and was slowly killing my beautiful Acer by the pond.

Apparently Acers have shallow, spreading roots which don’t like being disturbed. An Acer expert I consulted at the Malvern Spring Gardening Show had made the position very clear - either the Acer would die completely or the bamboo had to go. There was no question. It was a back and two fork-twisting, four days to dig all the bamboo up properly – and I was pretty sure I hadn’t put any of it in the compost bin.

Identifying the compost bin blockage was not easy. During Spring the top of the compost became very unpleasant. First it was a mass of worms and slugs and then, as it got dry, it became a mammoth ants nest. Identifying the blockage from above was not going to be pleasant or straightforward. So I got squeamish and didn’t try. Even if I lay on the ground and looked up through the little door at the bottom (really tricky and painful given its location and generally yucky as a prospect), I couldn’t see what was going on. So I left it and, over time, the “thing” in the compost bin continued to take over physically - and in my mind. It took on ridiculous proportions. I knew it was powerful and strong. It became a monster and I even became a little scared of it.
