Can strawberries go in your worm bin?
Yes, absolutely! Strawberries are almost ideal food for compost worms. Both the strawberries themselves (even overripe) and the green tops, stems, and leaves can go in the worm bin without problems. They are soft, moist, and contain many easily digestible sugars, so they are quickly converted into valuable compost. They primarily provide ‘green’ material that adds nitrogen to your bin.
How many strawberries can you add?
Strawberries can be added regularly, just like most other fruit scraps. Because they contain a lot of moisture, it is crucial to balance them with sufficient ‘brown’ material, such as shredded cardboard, paper egg cartons, or unprinted paper. Do not add a large quantity of strawberries all at once; spread it over multiple feedings to keep the moisture balance and temperature in the bin optimal. Your worms will naturally show how much they can handle.

What to do instead? Alternatives & waste management
Strawberries are so well suited for vermicomposting that there is usually no reason to use them for anything else if you have a Bonter! Should you have a huge abundance (more than your worms can handle), you could possibly process them on a traditional compost heap. But for daily kitchen scraps, strawberries are a welcome treat for your worms. They compost excellently together with most other fruit and vegetable scraps.

Tips for safe strawberry composting
Although not strictly necessary, you can optionally cut larger strawberries or the green tops into smaller pieces to further speed up breakdown. The most important thing with strawberries is that you always bury them well under the bedding (such as a layer of shredded paper or cardboard). The sugars quickly attract fruit flies if the scraps are left on top. Covering well is the key, and thanks to your Bonter’s integrated air filtration system, any odors (which can develop faster with fruit) will not leave the bin.
