Spring is here, and with that extra hour of sunlight upon us, it is time to start thinking about getting back out into the garden, or at the very least, laying down the foundation for this summer’s bountiful harvest. Dig through most of our trash bins (I’m not volunteering), and you will find that most of us have one major item in common – food waste.
Good for the Garden, Good for the Earth
According to the U.S. EPA, “Yard trimmings and food residuals together constitute 24 percent of the U.S. municipal solid waste stream.” And lest you think that your compostables are off to do just that in the landfill when buried underneath everybody else’s garbage, think again: Food and yard waste rots and emits methane, a global warming gas. According to NASA, methane is 20 times more potent than carbon dioxide.
Compare the landfill route with backyard composting, which adheres to natural systems and puts our food and yard waste back to work doing what nature intended – enriching the soil so it can grow more food.
Spring Into It
According to Jeffrey Simeon, the Backyard Composting Program Specialist for Santa Barbara’s Public Works Department, “While you can start composting any time of the year, spring is a great time to begin. As the air temperatures increase and rain falls or snow melts, the micro and macro organisms in the soil become more active.”
All you need to start your compost is the organic waste found in your kitchen, yard and garden. Outside, it’s warming up, gardens are waking up and melting snow is probably uncovering decomposing twigs and branches. Depending on the system you choose, you may also need to purchase a bin or some worms for vermicomposting.
A System for Every Lifestyle
Whether you live in an apartment and only have a small deck or porch, or you have a large yard and garden, there is a composting method that is right for you. According to The Answer is Backyard Composting
and Yard Waste Reduction, a booklet available online from Santa Barbara County Public Works, when deciding on a system, it is important to ask yourself these four questions:
- What materials do I want to compost?
- What volume of materials do I generate for composting?
- How much time and effort can I dedicate to the maintenance of a composting system?
- How much yard space, if any, do I have available for a composting system?
Depending on your answers, you can then establish a vermicomposting bin, an aerobic bin, an anaerobic bin or a multi-bin system. For example, vermicomposting and aerobic bins take up the least amount of space, so they are better for urban composters, but they also have less capacity for processing waste.
Make Way for New Matter
If you already had a compost pile in the fall, clear out the humus (nutrient rich finished compost) from your bin. If using the humus in your garden, Simeon recommends spreading it out for a few days on a plot of land to let the compost age a bit before planting, or you can just sprinkle it directly onto your lawn.
Start Collecting the Goodies
Compost ingredients are generally broken down into two main categories – “green” and “brown.”
“Brown” ingredients are leavings from your lawn and garden that tend to be older and dryer. They will take longer to decompose, but they are a necessary complement to the wetter “green” ingredients that may come from your kitchen or weeding efforts.
Leftover leaves and weeds are a good base ingredients when starting a new pile. You may also have tree trimmings, which should be chopped into small pieces, as they take a long time to break down. Add kitchen waste as it is available, and keep the pile moist in order to encourage the right level of decomposition, Simeon recommends keeping your pile as wet “as a wrung out sponge.”
You’re a Natural
No matter what type of composting system you use, be sure to utilize nature’s cycles. According to Simeon, “With all your plants and compost helpers (good bacteria, fungi, worms, bugs) waking up from the winter, your pile will be composting in no time. If you want to introduce these little guys to your new pile, you can add some of last year’s compost or just a handful of soil.”
Simeon also recommends patience, especially with a new pile and the changing season. He says, “Remember, composting takes time, so even if your pile isn’t hot and steaming it doesn’t mean you aren’t composting correctly; it just means you are composting more slowly, so don’t get discouraged.”
Composting is an excellent way to establish a sustainable waste system in your own backyard. If you need further incentive to get out there and start your own system, imagine all of the delicious fruits and veggies that you could be enjoying year-round thanks to your efforts this spring.
