Id be afraid of putting bannana in there unless it was precomposted or there was enough worms in my pots. Which there aren't yet 😣

I understand. It is a big differenc between homegrowing an plants in the nature
Here you have other possibilities :)

I think banana would be a great idea! Just have to let it rot for a week with some other fruit and leaves together. After could weeks. It's good for mixing with soil. Thank you for coming by! Any suggestions are accepted and appreciated.
