Posts Tagged ‘worm humus’

Have I mentioned most of the potting soil here leaves much to be desired?  As a result, over the past 6+ years, I’ve been experimenting with ways to enhance the soil I’ve been dealt to help my rooftop garden grow.  Besides, freezing (to speed up the fiber break down) and then adding green kitchen scraps, augmenting the soil with sawdust and sand, I’ve added worm farming to my arsenal.

Back in early August, blogger buddy and gardening guru Chris and I, armed with our new red bins, headed out to Sikanda (just outside Santa María del Tule) to purchase and be schooled in earthworm (lombriz, en español) farming.  P1130268

Our goal was to provide a nurturing environment for earthworms to go forth and multiply and to produce worm casting (aka: vermicompost, worm humus, worm manure) to enrich our soil.  Since then, I’ve spent the last five months keeping their home moist and feeding my worms more green kitchen waste, coffee grounds and tea leaves, and garden clippings.  Saturday, I finally harvested my first castings.

There are several ways to separate the worms from their castings.  I chose the photosensitivity filter method — laying cheesecloth over another bin filled with compost and placing it in the sun, I transferred a thin layer of my worms and their castings onto the cheesecloth.

Earthworms hate the sun and most quickly started burrowing down through the cheesecloth in search of cool moist darkness..  Once the worms had made their way into the moist compost of their new home (stragglers received hand-picked assistance), I removed the cheesecloth, now filled with worm-free castings, and dumped it onto my sifter, where I sifted the nutrient rich castings into my soil bin.
