Unfortunately, it does not work. Bonemealing grass blocks just creates foliage (short grass, flowers, etc.) around the block. Moss blocks on the other hand convert natural blocks around them to moss when bonemealing them.
Best thing to do is, if you have silk touch, get a couple of grass blocks and dot them around the dirt to encourage spread from multiple locations.
Just finished American McGee’s Alice. I have not played this since I first played it the year it came out (2000). I have not had this much fun with a game in a while. Also, have not experienced the drive to finish a game like I did this one in a good long while.
The game is janky and difficult to control but I just found it so much fun and the atmosphere of the game is fantastic.
I cannot wait to replay the sequel.
