Composting Success Guide

ðŸŒĄïļ Temperature Monitoring

Hot composting should reach 140-160°F in the center during the active phase. This heat kills pathogens and weed seeds while accelerating decomposition. Turn when temperature drops below 100°F.

💧 Moisture Management

Your compost should feel like a wrung-out sponge - moist but not dripping. Too wet leads to anaerobic conditions and odors. Too dry slows decomposition significantly.

🌊ïļ Aeration Importance

Oxygen is crucial for aerobic decomposition. Regular turning, proper layering, and coarse materials help maintain air pockets and prevent anaerobic decomposition that causes bad odors.

Troubleshooting Common Compost Problems

😷 Odor Issues

Symptoms: Bad smell, slimy texture, flies

Causes: Too much green material, too wet, not enough air

Solutions: Add brown materials, turn more frequently, ensure drainage

🐌 Slow Decomposition

Symptoms: Materials not breaking down, cold pile

Causes: Too much brown material, too dry, pile too small

Solutions: Add green materials, water lightly, increase pile size

Seasonal Composting Calendar

ðŸŒą Spring

  • Start new hot compost piles
  • Screen finished compost
  • Add yard waste from spring cleanup
  • Resume regular turning schedule

☀ïļ Summer

  • Monitor moisture levels closely
  • Add grass clippings gradually
  • Harvest early spring compost
  • Maintain regular turning

🍂 Fall

  • Collect and shred fallen leaves
  • Build final hot piles of season
  • Insulate bins for winter
  • Apply finished compost to gardens

❄ïļ Winter

  • Continue adding kitchen scraps
  • Reduce turning frequency
  • Plan next year's composting system
  • Maintain indoor worm composting

Using Your Finished Compost

🌚 Garden Amendment

Mix 2-4 inches of compost into garden beds before planting. Compost improves soil structure, water retention, and provides slow-release nutrients for plants.

ðŸŒŋ Mulch Alternative

Use partially finished compost as mulch around trees and shrubs. It suppresses weeds while continuing to decompose and feed the soil.

ðŸŠī Potting Mix Component

Screen finished compost finely to mix with other ingredients for homemade potting soil. Use up to 30% compost in potting mix ratios.
