I don’t know if this is the right category or not but this kelp is growing out of stone under ground is that normal?
Yes. You can plant kelp anymore, just tap a block below water while holding kelp.
It’s suggested that you still plant kelp on compost, sand, black sand, or dirt because it usually makes the kelp occupy the spot longer.
Blockheads logic at its finest.
Absolutely! We can haz lodgick!
Kelp does grow on stuff like rock irl, so blockheads might not be that far from reality.
