To avoid problems with odors, pests, reseeding, or slowing down the compost process, don’t put any of these items in your pile.
- Invasive weeds that spread by roots/runners — e.g. crabgrass, bamboo
- Weeds with seed heads (pull them before they set seeds)
- Meat, fish, dairy products, bones, fats, bread
- Large branches or pieces of wood
- Pressure treated woods
- Bar-b-que or coal ashes
- Dog or cat wastes
- Materials with thorns or spines-e.g. rose branches, cactus
