What You’ll Need:

A large plastic garbage bin with a lid A drill A 1/4 inch drill bit 2 bungee cords

Use the drill to create holes all over the plastic garbage can, including the lid and the bottom to allow air to circulate through. You can space these holes out at regular intervals, or get cheeky and create designs or words with them. By the time you’re done with it, this aerated bin will likely look as though a very bad marksman has been using it for target practice. The holes will be small enough that worms and other small insects can get in, but rodents can’t.

Once done, you’ll set the bin atop a couple of cinder blocks to let circulate through the bottom, and also to allow any excess liquid to drain out of it.

Start your bin by pouring a good 5 to 7 inches of dry leaves into it, followed by a handful or two of green/nitrogen materials. Pop the lid on that bad boy and secure it with the two bungee cords in a criss-cross pattern. Roll it around your yard a little bit to mix the green with the brown, and then set it back on its blocks to aerate. You’ll want to roll it at least once a week to ensure proper aeration, especially as you add more to it.

What Goes Into the Bin:

One key to backyard composting is to ensure that you have a high enough ratio of “brown” to “green” materials in there: these are also known as “carbon” and “nitrogen”, respectively. Brown/carbon materials are the dry component, while the green/nitrogen bits tend to be have more water content. For example:

Brown = dry leaves, dry hay/straw, small amounts of sawdust

Green =  grass cuttings, green leaves, vegetable/fruit scraps

Now, most resources will recommend that you have a 25:1 or 30:1 ratio of carbon:nitrogen (or brown:green) in your composter so you don’t end up with a stinking, slimy mess, but it all depends on what’s going into the bin. Some materials have higher carbon content than others, some scraps will take longer than others to break down, etc. ad nauseum. I don’t math well, so I just try to ensure that for every handful of green/nitrogen scrap I toss in, I add several large handfuls of brown/carbon to balance it out. So far, it’s all worked out just fine.

It’s best to do a bit of research when it comes to what can and can’t be composted, as there are many different lists online that contain every bit of compostable material imaginable, from cooked pasta to masking tape. Some items can be composted if your pile gets hot enough to break it down, but that’s a bit more high tech than the average backyard gardener wants to get. Personally, since I’m creating compost to be used in my vegetable and herb gardens (which are full of organic and heirloom plant varieties), I try to make sure that I only compost items that I’d like to use to feed my plants, and by extension, my family. You are what you eat, right?

What’s Great for Composting:

Dry leaves Grass clippings (must be dry!) Vegetable peels (cucumber, eggplant, squash/pumpkin, carrot) Sawdust (from untreated wood only, and sparingly) Corn cobs, husks, and silk (chopped to help them break down) Fruit peels and scraps, (apple, pear), but I don’t add citrus peels to mine. Some sources say you can (except for limes), but I tend to err on the side of caution and leave them out. Coffee grounds Shredded black and white newspaper Tea leaves Leftover stems and unused leaves of culinary or medicinal herbs Crushed nut shells, and any ground nuts left over from making milk (ground almonds, hazelnuts, etc.) Whatever isn’t baked with afterwards can be added to the pile. Droppings from pet birds (herbivore poop is okay too, so if you have a pet rabbit or goat, toss the poopings in!) Eggshells (have to be crushed before adding to the pile, as they break down slowly) Wood ash from the fireplace (used very sparingly, and mostly for pest control: most of my wood ash goes onto acidic areas in my garden to amend the pH levels there).

What You Should NOT Compost:

Used cat litter Wet grass clippings Any animal manure other than herbivore poop (including human, so no baby diapers in here either) Colored paper Animal products (meat, bones, grease/fat/suet, skin, egg yolks/albumen, fish, etc.) Milk products Diseased plants (you don’t want to transfer bacteria or fungus into your healthy, happy compost) Rice, raw or cooked Painted wood Walnuts Cooking oil Bread or baked goods (mostly because you don’t want to attract rats, racoons, or other animals) Coal/charcoal ash

It may take some time to establish a proper balance in your bin, but be patient, and just adjust things as they move along. If you find that your compost smells gross and seems a bit too wet, add a bunch of dry/carbon materials and let things rebalance themselves. Should you find that things aren’t breaking down properly, you might need some more green materials: throw some dry grass and vegetable peels in and give it a good roll.

If you’re diligent about tending your compost pile, the “black gold” that’ll form will be invaluable for your garden. It’ll take 2-3 months for everything to break down into usable compost, and the end result should have a rich, earthy, forest-y scent. Compost is so full of nutrients that it’ll nourish your plants into strong, healthy edibles. You can create compost tea from it as well, to help treat common plant maladies and give a vitamin-filled boost to your garden, like a superfood smoothie for your plants.
