8. What to leave out of a compost heap
- meat and other scraps likely to attract animals, especially in winter when decay is slow.
- thorny material (because thorns stay sharp).
- diseased material.
- weed seeds and seeding material (unless the heap reaches 82 degrees C).
- roots of dandelion and bindweed, bulblets of celandine, rhizomes of couch grass, and the below-ground parts of any perennial plants that you don't want to spread in your garden.
- leaves (instead put in separate wire netting enclosure or bag them up because leaf mould takes 2 years to form).
