This title came to me while putting some “mature” compost, what most would consider garbage, through the shredder in preparation to feeding it to my gardens. I feed my compost a fair amount of coarse material – twigs, sod, corn cobs, egg shells, etc.. They decompose to a point, and would completely break down to humus as all organic material must, but I don’t have the storage facilities for that many years. Hence, the shredding!
Is the shredding absolutely necessary – no! But it does reduce the material to a consistency that makes for a nice smooth seed bed. If the compost is destined for something like the raspberry patch or flower beds, then I don’t shred it, but the veggie garden gets the royal treatment – through the shredder it goes.
Since I use my own compost in my Soil Block mix, that too must be of a finer consistency, or the blocks will fall apart. In fact, for the mini blocks, I go one step further and actually pass the shredded compost through a 1/4″ hardware cloth screen. Is the work worth the little bit of effort – sure is, at least in my garden.
