What if you don’t have a lot of space for composting as Ruth commented awhile back? Your leftover salad greens, apple cores, egg shells, and gnarly vegetarian leftovers can go straight to the root of your garden when you use this method, which is ideal for urban gardeners.
Toss compostable items into your blender so that it’s about a third full. Fill the container with water and blend until very finely chopped. Walk out to the garden and with a trowel, dig a small hole alongside a garden plant and pour some of the contents of the blender in. Cover with dirt and let the worms and microbes go to work. One blender full will fill three small holes (or, of course, one larger one). It’s so easy, I even did it single-handedly (LEFT-handedly) so I could take a video:
