QUESTION: Can garlic go in compost?
ANSWER: Yes, garlic can be composted but there are a couple of reasons why you might want to avoid using garlic in your compost, especially in large quantities. Garlic cloves have a tendency to re-sprout if left whole, so if you are going to compost your garlic, make sure to chop them up so that they won’t start growing out of your compost bin. Also, alliums like onions and garlic are not great for worm composting systems, as worms tend to avoid chomping on garlic and other strongly flavored or spicy food items.
So if you are adding garlic to your compost, try to limit the amount that you add. Instead of composting your excess garlic, why not replant your cloves and grow more garlic for future use?
