Vermicomposting
I started my first worm bin in Brooklyn about 10 years ago. For me it’s the best way to compost if you do flower pot gardening. The worms convert your table scraps directly into castings directly usable in pots and flower boxes.
Now that I have a full back yard, I still keep a worm bin. Every time I plant something new, worm castings are part of the mix.
Here in Phoenix we are lucky to have a great local worm farm. Even as a veteran vermicompster, I learned a lot from their class and tour.
