Passion fruit shells

[HollieHock]

We go through an awful lot of these and the shells seem such a waste. I do need some mulch and wondered if anyone has tried drying these out and sticking them in the food processor?

Would this work?

I have no idea if it would work but could you use ( some at least ) as mini seedling pots that you can bury when planting out?

Thanks for the idea. I'm a novice gardener but I have some nasturtium seeds to plant soon. Would there be a benefit of using the passion fruit pods for that?

If you have a garden, then you could start a compost heap in the corner.

@HollieHock in my experience nasturtiums don’t need any help whatsoever to grow from seed. You can just chuck the seeds around and they will get on with it. They are lovely but can get a bit unruly and they self seed vigorously. The seedlings are easy to pull out if you want to get rid of them.

I found an incredibly tedious video on YouTube, I've no idea of the poster's horticultural qualifications, there are no comments and only six thumbs-ups ... but they think shells are "gold for your plants"

@HollieHock , I have no idea if it would work but I can't see the harm in trying.
As @Koulibiak said they grow very easily anywhere . Do you know that the flowers and leaves are edible, they have a pleasant peppery taste.

Good find but yes agree re tedious. I've never seen anyone cut a passion fruit like that - thought he was going to cut his hand.
I will try the drying in oven next time I put it on and then in to processor as he did but don't think I'll try the others. Thanks

I think waitrose sell sorbet that’s served in a passion fruit shell, perhaps use yours to make your own?

I found this: https://www.taste.com.au/recipes/easy-passionfruit-skin-jam-recipe/39jf6b5f

I have several very productive vines, and consequently, literally kilos and kilos of shells...They just go into the compost and quickly become as one with the rest of the stuff. Any seeds left in the shell grow and you have dozens of little plants coming up in the compost heap. They are very vigorous little things.

@pollyglot interesting. Unfortunately I can't have a compost heap as I love passion fruit flowers.

Thanks all. I'm not going to be making sorbet or jam though :)
