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.
Or at least as much of it as I could force on to a PDF and then convert to a JPEG. It’s harder and slower than you’d think. I suppose it would have made more sense to do the plan before the seed order but we had a clear idea of what we wanted to grow and – as always happens – it’s only when you start the detailed planning as to where exactly things are going to go, that you realize you just need a few more square metres. But we don’t have a few more square metres and so it’s going to be a very tight fit. There’s another challenge, inasmuch as some crops come out in time to get a second crop in afterwards, but the very thought of trying to plan successions that way (although the software allows it) – makes my head spin.
All this planning is attributable to my being felled by a cold and kept indoors with only my protestant work ethic for company. Oh and miserable weather just about topped it. But after three or four days, the streaming eyes, the sneezing and the hacking cough have subsided a bit and we were able to go up to the allotment clutching the print-off in order to see just how difficult the plan is going to be. It’s now true midwinter and growth has slowed almost to nothing among the plants. It’s as if everything is taking a break and waiting for a sign to wake up again.
But one group of residents has not stopped for a moment this winter. The compost heap has become a wormery without any effort at all on our part. With plant growth at a standstill the only thing going on to the compost heap has been our household green waste – peelings, eggshells, cardboard, coffee grounds and leaf tea all go on every couple of days but the heap never grows. Down at the bottom of the heap the magic has happened and when I separate the two layers I’m confident we’ll have excellent compost. Lifting up the old carpet and the cardboard on top reveals an astonishing amount of worm activity. I’ll need to be careful when the heap is turned into its new home. The worms have found their own way into the heap and they are really thriving, so I’d quite like to start a proper wormery, but what would be the point when the system is working so well without any interference from me?
Now the new raised beds are almost finished there’s still a bit of old-fashioned digging to do in order to remove the last of the bindweed and couch before we forsake digging altogether and rely on our friends the worms to do the work for us as they take the mulch down into the ground. It’s a win-win situation, but I’m not sure the summer is going to be all about lounging around drinking Pimms. It’s going to be just as hard work to source and produce the quantity (about 10 cubic metres) of compost we’ll need to run the no-dig system really well. And there in the middle of the plan are the three new compost bins that will be the engine of our productivity – when I finally get around to building them.
