Composting arugula scraps with worms
Arugula scraps, such as leftover or no longer fresh leaves, can be added to your Bonter worm bin. This leafy green decomposes quickly, but due to its moisture content, it is important to add it in moderation and combine it with dry material for a healthy composting environment.
Can arugula go in your worm bin?
Yes, arugula is suitable for your Bonter worm bin. It is a soft leafy green that is broken down very quickly by the worms and microorganisms. As with other types of lettuce, the high water content is the most important factor to consider. Too much arugula can make the bin too wet if not well-balanced, which makes the worms uncomfortable and can potentially cause odors. The slightly peppery taste of arugula is generally not a problem for the worms.
How much arugula can you add?
Add arugula scraps in moderation to your Bonter. Limit the quantity to small handfuls at a time, and add it as part of a diverse mix of waste. Combine arugula, like other moist waste, always with a generous amount of dry, carbon-rich material such as shredded cardboard, paper, or egg cartons. This helps absorb the extra moisture and keep the structure of the bedding airy. Pay close attention to the reaction of your bin and add extra dry material if needed.
What to do instead? Alternatives & waste management
Because arugula can go in the worm bin in moderation, you don’t have to throw away small scraps. Arugula that is no longer fresh enough for salads can sometimes still be processed into a pesto, soup, or wilted into warm dishes. An outdoor compost heap is also an option for larger quantities of leafy greens, where moisture is less likely to be a problem. Try to minimize waste by using arugula as fresh as possible.

Tips for safe arugula composting
Arugula scraps require little preparation. You can put the leaves and thin stems in as they are, or optionally tear them a bit smaller to speed up decomposition slightly more. Mix the arugula thoroughly with a generous amount of dry bedding material before adding it. This is essential for moisture management. Bury the mix under the top layer to discourage fruit flies. After feeding wet waste like arugula, add extra dry material on top. Although your Bonter filters odors, an overly wet bin can smell musty; so always ensure good moisture balance.

Frequently asked questions about composting arugula
Can arugula go in the worm bin?
Yes, arugula is suitable for the worm bin, but like other types of lettuce, it is important to add it in moderation and combine it with dry material due to its high moisture content.
Does arugula cause odors in the worm bin?
Arugula itself does not smell strongly, but due to its high moisture content, an excess can contribute to an overly wet bin. An overly wet environment can lead to anaerobic decomposition and consequently to musty odors, despite the Bonter filter. Ensure a good moisture balance to prevent this.
How quickly does arugula decompose in a worm bin?
Arugula decomposes very quickly in a worm bin. Because it is a soft and leafy material, the worms and microorganisms break it down rapidly, often within just a few days.
Is arugula different from other types of lettuce for composting?
No, arugula behaves similarly in the worm bin to other types of lettuce such as butter lettuce or iceberg lettuce. All types of lettuce are moist and require attention regarding moisture balance and combining with dry material. The slightly peppery taste of arugula is not a problem for the worms.
Is the slight spiciness of arugula a problem for the worms?
No, the slight peppery taste or spiciness of arugula is not a problem for the worms in normal quantities and as part of a varied diet.
