...compost!
how's, why's, when's, and where's:
Why compost? compost helps retain moisture, attracts worms and bugs into your soil (that's a good thing), provides gentle and easy-to-absorb nutrients for the plants, hosts beneficial bacteria and microorganisms, acts as a mulch by stabilizing soil temperature and suppressing weeds, AND is a great way to recycle your kitchen and yard waste and some paper products. organic gardeners (the only way to be, in my opinion) live by the mantra, "
grow the soil, not the plants". this means that by putting most of your time and energy into creating healthy soil, you have naturally strong and disease-resistant plants as a by-product (without nasty pesticides, chemicals, and synthetic fertilizers).
Where to compost? pretty much anywhere you don't mind a little bit of a mess (certainly not next to your patio where you entertain, for example). many gardeners use the
three-bin system, which entails using a set of three bins or even just piles of compost, in succession of least-finished to mostly finished compost. as you add waste to the first pile and turn it to let it break down and decompose, the second bin you add the partially degraded compost to the second bin, and then in turn the third bin receives the mostly finished or completely ready compost. by using this method, you always have a fresh pile to receive your yard waste and kitchen scraps, and a finished pile ready to be used in your garden and pots. i add a continual supply of kitchen scraps to a covered plastic tumbler, similar to a trashcan, which will result in one big "crop" of compost at the end of the season, rather than a steady supply of compost like the three-bin system. you can have a heap enclosed by fencing, chicken wire, old recycled wooden pallets, whatever. just make sure it is able to be covered (compost needs heat and only a minimal amount of rainwater) and that occasionally you can access it to turn it (with a pitchfork, shovel, whatever.) compost can be fast, made in a few weeks under a high-heat aerobic pile, or very slow--basically a slowly rotting pile of leaves-- that takes several seasons to finish.
How to compost? bear with me as i get (slightly, slightly, SLIGHTLY) chemistry-ical on you. compost needs both a carbon source and a nitrogen source, as well as air and water. air prevents anaerobic (i.e. stinky) conditions from forming and water nourishes the bacteria and keeps them moist (aka alive). your carbons, or "
browns", are things like sticks, twigs, old mulch, bark chips, newspapers, paper bags, etc...anything dead-ish or dry. your nitrogen source-- the "
greens"-- are the fruit peels, old rotting veggies, grass clippings, rabbit poop (...thanks, Mopsie)...basically anything alive or mushy, wet, etc. what else can you compost? any paper that isn't glossy (picky composters check on the ink...soy-based is best), eggshells, guinea pig or hamster bedding, expired plants from your garden, leaves in the fall, your christmas tree once chopped up, etc etc etc... what can you NEVER EVER EVER compost? human waste, cat or dog or pig feces, meat products, dairy, mayonnaise, magazine papers, plants treated with pesticides, plants with diseases like mold, fungus, powdery mildew, invasive plants or weeds with seed heads (unless your pile is running at a super-high temperature)...you get the point. aim for a 60:40 ratio of nitrogens to carbons. keep the pile moist, sprinkling with a hose if you need to, and keep it covered (black plastic works great) to accelerate the heat and keep rain from slushing it all away into a moldy mildewy mess. turn it occasionally (about six times a season). compost, if maintained properly with the balanced ratios, should not stink or attract any pests. it actually smells quite sweet and earthy when finished correctly.
and, finally....
what for?
i use my compost to top off houseplant soil, to mulch beds in need of a boost, to mix into new containers' dirt, to rake into new beds i'm digging, to brew compost "tea" and spray on plants' foliage, and to cover beds in the fall to help them winter over. use it in place of any mulch or fertilizer that you would normally use.
that's all there is to it! add worms to your beds along with your compost and you get bonus points.
