Composting beets in your worm bin
Beets, whether beetroots or other varieties, can be processed in your Bonter worm bin. The dense structure of the bulb requires a bit more attention than, for example, soft vegetable peels. With the right approach, you can successfully compost beet scraps too.
Can beets go in your worm bin?
Yes, beets (the bulb) can go in your worm bin, but they fall into category B – add in moderation. The beet bulb is quite dense and watery, meaning it can take longer to break down than softer materials. Beet greens, on the other hand (the leaves and stems), receive an A rating and compost quickly and easily. So, be more cautious with the quantity of the bulb.
How much beets can be added?
Add beet bulb scraps (such as peels or small pieces) only in limited quantities. Due to the high moisture and sugar content, it is crucial to balance this with plenty of dry ‘brown’ material, such as cardboard or paper. This helps absorb excess moisture and prevents the contents from becoming too compact. Too many beet bulbs at once can lead to anaerobic (low-oxygen) conditions, which can cause unpleasant odors. You can add beet greens more generously, again in combination with brown material.
What to do instead? Alternatives & waste management
If you have a lot of beet bulb scraps, or if you notice your worm bin is struggling with the amount, there are alternatives. Larger quantities are better suited for a traditional outdoor compost heap. Small scraps that don’t fit in the worm bin can go with the organic waste if that option is available. However, by adding beet bulb in moderation and smartly prepared to your Bonter, you maximize the amount of waste you can process at home.

Tips for safe beet composting
The key to successful beet composting is reducing the size. Cut beet peels and pieces of the bulb as small as possible (ideally 1-2 cm). The smaller they are, the faster the worms and microbes can do their work. Bury the beet scraps well under a layer of dry bedding. This helps keep fruit flies at bay and ensures good aeration. Add extra dry cardboard or paper to compensate for the moisture from the beet bulb. You don’t need to cut beet greens as finely, but burying them is also recommended. With Bonter’s air filter, unwanted odors stay within the bin.

Frequently asked questions about composting beets
Can both the beet bulb and the greens go in?
Yes, both are allowed. The bulb in moderation and finely chopped (Rating B), the greens are highly suitable (Rating A) and compost quickly.
Do I need to peel beets before they go into the bin?
No, peels do not need to be removed. However, make sure the peels from the bulb are very finely chopped.
Can cooked beet go in the worm bin?
No, preferably only add raw beet scraps. Cooked vegetables can contain too much moisture and unsuitable additions like salt.
How long does it take for beets to compost?
Beet greens compost quickly, often within a week or two. The beet bulb, even finely chopped, can take longer, sometimes several weeks to a month, depending on the conditions in the bin.
Can beets cause unpleasant odors?
If you add too much beet bulb, especially without enough dry material, it can become moist and compact, which can cause odor. Feeding in moderation, cutting finely, and balancing with brown material prevents this, and the Bonter filter helps extra.
