Composting passion fruit with worms
Passion fruit peels and the leftover pulp with seeds are suitable for your Bonter vermicomposter but require some attention when adding them. The juicy inside and seeds are processed quickly, but the peel is tough and requires some time and help with breakdown. Read here how best to process passion fruit waste.
Can passion fruit scraps go in your worm bin?
Yes, passion fruit peels, the remaining pulp, and the seeds are allowed in the worm bin. The pulp and seeds are soft, moist, and sugary, so they break down very quickly and are direct food for worms and microorganisms. The peel, however, is quite tough and fibrous, which slows down breakdown. The small seeds are digested, although the hard kernels within them may compost slower. Passion fruit primarily provides ‘green’ material.
How much passion fruit can you add?
Add passion fruit peels and scraps regularly, but in balance with other waste and sufficient ‘brown’ material (shredded cardboard, paper). Passion fruit pulp contains a lot of moisture and sugar, so always compensate for this with a generous amount of dry material to prevent your bin from becoming too wet or too attractive to pests. Do not add too many peels at once, but add small quantities, spread throughout the bin. Watch how quickly the peels are processed; if they accumulate, reduce the quantity or cut the peels smaller.
What to do instead? Alternatives & waste management
Passion fruit waste is well suitable for the Bonter if properly prepared and added in the right quantities. Should you have a large quantity, a traditional compost heap is a good alternative. There, the tough peels can be better processed in a larger mass. Try to prevent food waste of the delicious pulp and seeds by eating them or using them in dishes; that is the most efficient ‘processing’. The worm bin is an efficient place for the leftover peels and small pulp/seed scraps.

Tips for safe passion fruit composting
Cut passion fruit peels into smaller pieces (about 2-5 cm) to speed up breakdown. Always mix passion fruit waste (peel and pulp) with a generous amount of dry ‘brown’ material (cardboard, paper) to absorb excess moisture and ensure good structure. Bury passion fruit scraps well under the bedding. The high sugar content attracts fruit flies if left on top. Covering well is crucial, even with the effective Bonter air filtration system. This helps stop unwanted pests at the source.

Frequently asked questions about composting passion fruit
Can passion fruit peels go in the worm bin?
Yes, passion fruit peels are compostable, but they are tough and break down relatively slowly. Cutting them into smaller pieces helps speed up breakdown.
Do I need to remove the seeds from passion fruit?
No, the seeds, including the small hard kernels, are digested by the worms. You do not need to remove them from the waste.
Is passion fruit too moist for the worm bin?
Passion fruit pulp is very moist. It is essential to always add a generous amount of dry ‘brown’ material when adding passion fruit waste to maintain moisture balance.
Does passion fruit attract pests?
Yes, due to the high sugar content, passion fruit quickly attracts fruit flies. Always bury passion fruit waste well and deep under the bedding.
What about the tough peel, does it break down?
The peel is tough and breaks down slower than the pulp. Cutting it small is important, and add it limitedly so it does not accumulate in the bin.
