QUESTION: Can flowers go in compost?
ANSWER: Flowers, like most other plants, can be used as a composting ingredient. Fresh flowers should be considered green compost material, while dried flowers should be considered brown compost material.
Don’t add any flowers to your compost pile that died from any kind of plant disease, as the disease could infect your compost and then spread to your garden when you amend your soil.
Flowers that come from the florist are fine for composting.
