Pick a method that fits your space and commitment level, then start tossing in kitchen scraps. Composting does not need to be complicated, and California's mild climate makes it easier here than most places.
The three most common home methods are a bin, a tumbler, or an open pile. For most Santa Cruz yards, a simple two-bin system works well: one bin receiving new material while the other finishes breaking down. Tumblers are good for smaller spaces and keep rodents out, but they produce less volume. Open piles work if you have room and do not mind the look. UC ANR's composting guide breaks down the pros and cons of each method and provides detailed instructions for getting the ratio right.
The core rule is balancing "greens" (nitrogen-rich materials like fruit scraps, coffee grounds, and fresh grass clippings) with "browns" (carbon-rich materials like dried leaves, cardboard, and straw). Aim for roughly 3 parts brown to 1 part green by volume. Keep the pile as moist as a wrung-out sponge. Turn it every week or two, and you will have usable compost in 2 to 4 months.
Worth knowing: California's SB 1383 law requires cities and counties to divert organic waste from landfills. Santa Cruz County offers curbside green waste pickup, but home composting gives you a better product and keeps nutrients in your own garden. If you have limited outdoor space, worm bins (vermicomposting) work well indoors or in a garage, and red wiggler worms process scraps quickly with almost no odor when managed properly.
This week: Set up a collection container in your kitchen (any lidded bucket works). Save a week's worth of fruit and vegetable scraps, then layer them into a bin with twice as much shredded cardboard or dried leaves.
