The problem: giant jungle trees don't seem to grow anymore after the bonemeal nerf. I used a few bonemeal stacks to make 4 saplings grow, first using it in one sapling and then using it in all of them, but it didn't work. It's not a big issue, just another little thing to add to the list
When i used bonemeal on wheat it took only 1-3 stages usually sometimes 4 stages but that was the farthest stage I got.
this bonemeal issue is driving me nuts.. it is indeed on my single player game, i was so frustrated that it just... sparkles, and never grows. >.< hopefully it shall be fixed soon.
This is If your tree has noting near it. For Tree machines or tree farms, I have commonly had to use 12 or more bonemeal to get 1 sapling to grow .
