Organic Composting: Turn Waste into Garden Gold

Composting transforms 20-30% of household waste into the single most valuable soil amendment—saving landfill space, reducing methane emissions, and eliminating fertilizer costs.

What Is Compost?

Not just decayed matter, but applied microbiology—a complex ecosystem of thousands of microorganism species breaking down organic materials into stable humus. Done correctly: no odor, no flies, just rich, dark, earthy-smelling material.

What to Compost

Excellent (Quick Decomposers/Activators)

• Grass clippings
• Young weeds (no seeds)
• Vegetable/fruit scraps
• Coffee grounds, tea bags
• Plant trimmings

Good (Bulk/Structure)

• Dried leaves
• Straw/hay
• Older plant material
• Shredded newspaper/cardboard

Slow (Pre-process First)

• Woody stems/branches — chip or shred
• Corn cobs/stalks — chop
• Nut shells — crush

Avoid

• Meat, dairy, bones, oils — attract vermin
• Diseased plants — pathogens may survive
• Weed seeds — may not reach killing temperatures
• Pet/human waste — parasite risk
• Herbicide-treated grass — chemical persistence

Bin Options

• Free-standing pile — works if large enough (3×3×3 ft minimum)
• Commercial bins — wood or recycled plastic, neat, contained
• Tumblers — easy turning, faster decomposition
• Worm bins (vermicomposting) — indoor/outdoor, premium castings

Four Requirements for Success

1. Air — loose, mixed piles reach 130-150°F, killing weed seeds/pathogens. Turn occasionally.
2. Moisture — damp as wrung-out sponge. Water if dry; avoid waterlogging.
3. Particle size — smaller = faster. Shred/chop large materials.
4. Nitrogen — microbes need it. Add grass clippings, manure, or organic fertilizer (1-2 cups per 4 bushels leaves).

Timeline

• Managed pile — ready in 3-6 months (fall leaves → spring use)
• Neglected pile — 2-3 years
• Finished compost — dark, crumbly, unrecognizable original materials

Municipal programs (like Manchester's brown bin collection) make composting accessible even without yard space. Whether DIY or curbside, composting closes the loop—returning nutrients to soil instead of sealing them in landfills.
