Every now and then, when we open up one of our compost piles after they’ve been sitting for several months doing their thing, we uncover a pile which hasn’t quite broken down everything the way we want or we find lots of plastic strips that were not removed from boxes. Sometimes the odd cake box wasn’t waxed like we thought but rather plastic coated and causes issues in the composting process.
While our wonderful composting organisms try their darnedest to break down the plastics, it’s evident that the plastic short circuited the decomposition on the underside of the deposit. When these frustrations arise, we rise to the challenge and create our spud-compost-mansion.
“What on earth are you on about?!?!” you say. Put simply, it is a chicken wire basket that is lined with mulch on the bottom, composted straw around the sides, half finished compost on the core and spuds all around!
Here is one we started today…
The wire basket is held in place by bamboo stakes and since we were being lazy, we used our electric mulcher to break down some weeds into a fresh mulch bed.
I’d like to say that our logic is based on scientific fact… Rather it’s based on observation. We need to ensure that the too much moisture doesn’t leach out from the pile, and anyone who’s mown a lawn before and left a pile of clippings on the garden can attest to the fact that, fresh lawn clippings create a dense also impenetrable layer. So this is our retention mulch.
The next layer is rotten straw. We place a good wad of it on top of the mulch in the wire basket, then start lining the sides of the basket with it. Here is a pic of just that.
Next, we shovel in a layer of partially finished compost and add our chitted potatoes around the straw edges and back fill it with more compost.
Voilla! You very own compost-potato-mansion.
Once the spuds have sprouted, be prepared to keep adding straw lined walls and compost backfill all the way to the top of the wire basket. We wished we had a photo of last years’ one. It was awesome!
This design tends to keep possums away from you spuds too, which is handy in an urban setting, and then when it’s time to harvest the potatoes, you don’t need to do anything special than pull apart the wire mesh, harvest and spread out the spent compost on your garden. Almost no work at all!
We have started setting up a few of these baskets all around our garden so that when we are weeding, we slowly fill the basket and it composts away. Then we can use it straight in the garden without having to use a wheel barrow to cart it around. Win-win!
