Composting green asparagus scraps with worms
The woody ends of green asparagus don’t have to go to waste. With a little preparation, you can add these scraps to your Bonter worm bin. They contribute to your compost, although they require a bit more patience to digest.
Can green asparagus go in your worm bin?
Yes, the scraps of green asparagus, such as the ends you snap off, can in principle go in your Bonter worm bin. However, these parts are often very fibrous and tough. This makes them slower to digest for the worms and microorganisms compared to softer green waste. They can be added, but with attention and the right preparation.
How much green asparagus can you add?
Add green asparagus scraps in moderation. Limit yourself to small quantities at a time, and spread out the additions over different feedings. Due to their fibrous nature, it takes a while before they are fully broken down. Always add them as part of a varied mix of kitchen waste and ensure sufficient carbon-rich bedding material to maintain good structure and moisture balance in your Bonter. Patience is a virtue here.
What to do instead? Alternatives & waste management
The ends of green asparagus are fine for the worm bin, but there are also other uses. They are excellent for making broth, which forms a delicious base for soups and sauces. This is a zero-waste way to utilize the flavor. You can also add them to an outdoor compost heap. If composting is really not an option, then discarding is the last resort. Always think of reuse first!

Tips for safe green asparagus composting
The most important tip for green asparagus scraps is: make them as small as possible! Finely chop the fibrous ends to speed up the decomposition process. Add the finely chopped scraps along with other, more easily digestible food and bury it under the bedding layer. This helps discourage unwanted visitors and ensures that the worms can access it better. Although they are fibrous, they generally do not cause strong odors, and the Bonter filters the air anyway.

Frequently asked questions about composting green asparagus
Can the hard, woody ends of green asparagus go in the worm bin?
Yes, but it is crucial to chop them very finely first. Large, fibrous pieces break down very slowly.
How quickly do green asparagus decompose in the worm bin?
Green asparagus, especially the fibrous ends, decomposes quite slowly compared to softer vegetables and fruits. They remain visible in the bin longer while the worms and microbes work on them.
Do I need to do anything special with asparagus peels?
Green asparagus is usually not peeled, so you only have the ends. If you peel white asparagus, you can add the peels (also finely chopped) in the same way as the ends of green asparagus.
Can cooked green asparagus scraps go in the worm bin?
Yes, cooked green asparagus scraps (ends), provided they are without salt or unsuitable additions, can go in the worm bin. Cooking makes the fibers slightly softer, which can promote decomposition, but still make them very small and add in moderation.
Can the entire fibrous stalk (not just the end) of green asparagus go in?
The entire fibrous stalk can in principle go in, but it decomposes very slowly. It is advisable to compost only the snapped-off, tougher ends and chop these very finely.
