Any London groups for swapping seeds or plants?

Hi everyone,

I’ve recently revamped my garden and I’m getting really into plants (still very much a beginner though!). One thing I’ve realised is that seeds often come in big quantities, and it feels a bit wasteful when you only need a small amount. It would be amazing to share or swap seeds/seedlings/cuttings with other local plant lovers.

Does anyone know if there are any London-specific groups for plant or seed swaps? I found a couple of Facebook groups but they seem quite general or not particularly London-focused.

Alternatively, would people be interested if something like this existed -maybe a small community for swapping plants, seeds or cuttings in London?

Would love to connect with other gardeners and learn from people who know what they’re doing.
