Composting parsnip scraps with worms
Scraps from parsnips, such as peels, ends, and harder pieces, can be added to your Bonter worm bin. Due to their firm texture, they require a bit more time and patience to compost than softer types of vegetables. With the right preparation and moderation, however, they can be processed well into valuable compost.
Can parsnip go in your worm bin?
Yes, parsnip scraps are suitable for your Bonter worm bin, but with the note that they break down quite slowly. Parsnip is a root vegetable with a dense and fibrous structure; the peel and core, in particular, can be tough. They are not harmful to the worms but remain visible in the bin longer while the worms and microbes work on them.
How much parsnip can you add?
Add parsnip scraps in moderation to your Bonter. Limit yourself to small quantities of peels or snippets at a time and ensure they are well mixed with other, faster-digesting waste. Due to the slow breakdown, it is not advisable to add a lot of parsnip at once; spread it over different feedings for balanced composting.
What to do instead? Alternatives & waste management
Because parsnip can go in the worm bin in limited quantities, you can compost small scraps perfectly well. Larger or thicker pieces that you don’t want to compost can be used to make broth. This gives a delicious, slightly sweet flavor. A traditional outdoor compost heap is also a suitable place for parsnip scraps. Try to prevent food waste by being creative with leftovers and giving them a useful destination.

Tips for safe parsnip composting
The most important tip for parsnip scraps is size reduction! Cut the peels and tough pieces as small as possible, preferably into snippets or small cubes less than 1 cm. This increases the surface area and significantly helps the worms with the slow breakdown. Mix the parsnip snippets with other waste and bury it well under the top layer of the bedding material. Be patient, as you will likely see the fibrous parts of the parsnip longer in the bin than most other vegetable scraps. Your Bonter filters odors effectively.

Frequently asked questions about composting parsnips
Can parsnip peels go in the worm bin?
Yes, parsnip peels can go in the worm bin. However, it is important to cut them very small or grate them because they are fibrous and otherwise digest slowly.
How quickly does parsnip decompose in the worm bin?
Parsnip, particularly the fibrous and dense parts, decomposes relatively slowly in a worm bin. It takes longer for it to break down completely than with softer types of vegetables like leafy greens.
Do I need to make parsnip small before I add it?
Yes, absolutely! Reducing the size of parsnip scraps, especially peels and harder pieces, is crucial to speed up breakdown by the worms. The smaller, the better.
Can the sweet smell of parsnip be a problem in the worm bin?
No, the slightly sweet, earthy smell of parsnip is not a problem in a healthy worm bin and generally does not attract pests if the waste is well buried. The Bonter filtering system also ensures that no odors escape.
Can I put cooked parsnip scraps in the worm bin?
Yes, cooked parsnip scraps can go in the worm bin. Cooked parsnip is softer than raw and will therefore possibly digest slightly faster, but still add it in moderation as part of a varied diet.
