Compost Tetris

Over the last few weeks I have been slowly doing the almost yearly job of moving compost from one bin to the next. Our compost gets turned twice before it is considered ready for use. We have five compost bins and of course there is a system for how we utilise them. We use a sawdust bucket system for our toilet, we’ve been using this system for ten years now and it works really well for us. We make our own sawdust using our power planer, it costs us nothing to make as we have the timber on our land and we have all the electricity we need for using power tools.

We put both cooked and uncooked kitchen waste into buckets until we have two or three buckets filled, then every time we need to empty the compost toilet bucket we also empty the kitchen-waste buckets, covering everything with a layer of cut grass and rushes. We use one compost bin until it is full, the bins are roughly 4foot square. When the bin is nearly full I start the process of moving the compost in the other bins.

Imagine that all the bins are full and that the bins are A, B, C, D and E in that order and they are all built in one row. Bin A is nearly full so I begin by emptying bin C and putting the soil around trees, creating a new fruit bush bed or topping up a fruit bed. I keep some of the soil to close the bin which is almost full. I then shovel the contents of bin D into bin C and then I shovel the contents of bin E into the now empty bin D. Now we are ready to finish filling bin A and when it is full I close it up by covering it in grass and then topping with soil. Bin E is now ready for use.

It takes roughly nine months to fill a bin, sometimes longer depending on settlement in the bin. So every year I get to play Compost Tetris.

We always keep a pile of cut grass beside the compost bins which sometimes needs replenishing. Sometimes this requires cutting grass and rushes however today I was able to move some which had been cut over a year and half ago – quite a workout!

When I was resting between runs with the wheelbarrow I was struck with the beauty of the sunlight glinting in raindrops hanging from the bare whitethorn  (hawthorn) branches in a nearby hedge. Such beauty is never far away here and I am always grateful to receive it.
