I upgraded my 1.14.4 world to 1.15.2 (final release version) earlier this year and have become interested in trying out the new bee feature.

Problem is finding the little buzzers and I read on the Minecraft wiki that trees planted by the player have a 5% chance of spawning a bee nest. 

But I've had no luck with this and feel like I am wasting bonemeal and time. 

I have also read in reddit and youtube comments that this was a one-off feature from the snapshots/pre-release versions that got removed from the final 1.15.2 release?

If this is true, I may be left with either exploring unloaded chunks in my world or just spawning it in my village via creative mode.

Hoping to get some clarification and closure on this

EDIT: I tried it out in a creative world and caused it to happen and when I returned to my regular survival world and planted a tree near a flower, a bee nest spawned. Now I have a nice group of bees!
