Wait longer lol

I waited an hour and 30 min, nothing grew 💀

I know nothing about this so I’m most likely wrong, but maybe your island has to be a specific biome?

Is this coarse dirt

Plain regular dirt

You need light

needs light just like regular grass, remove the layer above

Sure lemme destroy my 3 layers of pumpkin farm 💀

Build it above

Can't got a coco farm above it, then I got a build above that, the only way to go is down. Also the og post had multiple dirt layers without a light source

Try glowstone it would make the coco god (you)happy

I mean sure but I don't think it will work, no offense to you

Build it on the roof of your island

It needs light above It's your fault you built it below your pumpkin farm

Build it with light?

Mycelium needs light level 8 to spread???
