Back at the Potwell Inn allotment to install some fronts on the new compost bins this afternoon. We were eager to see whether the worms had sorted themselves out after being moved into a new home and we were delighted to see that they had resumed their activities at the top of the heap. They’re not keen on daylight so you need to be pretty sharp to get a photo before they all disappear. One thing that interested us greatly was how they appear to enjoy the cardboard in the heap. Yesterday I threw all of the half -rotted carboard that we took off the California cylinder into the heap and today the worms seemed to be congregating especially densely around it. One of the challenges with any heap is keeping the moisture level right. I heard somewhere that it should be moist but not wet enough to squeeze water out. This lot looks pretty wet, but the presence of woodlice suggests it’s not too wet. Having mixed it all up whilst turning it yesterday there’s quite a mixture of fresh material and worm cast – that’s the dark looking stuff that contins all the goodess. It’s a miraculous thing to watch, plant material decomposing through the action of all manner of fungi and bacteria and then being passed through the worms and turned into highly valuable garden gold. I swear I can hear the heap shouting “feed me now” every time I walk down the path. So that’s bin number one and we’ll probably stop feeding it when there’s enough fresh material in the adjoining bin to attract the worms through the gaps in the structure. I’m assuming that once the fungi and bacteria have kicked the process off, the worms will move next door where they’ll find a greater abundance of food. That’s the theory – bearing in mind that we had no idea they would colonize the cylinder so abundantly. If they’re happy they just seem to keep multiplying, presumably until their appetite fails to be matched by the food supply. Our only task is to feed and to turn the heaps regularly.
