Isn't really simple at all? And you say you used to play skyblock .. Just grind up some Cobblestone then.. Make (as many as you like) 5x5 platforms where in the center of them you plant your tree .. This method has worked for me and is still working perfectly.. And also stop crying about such a stupid issue (I wouldn't even call it an issue)
Im not crying about an isue and i realy want my vote coins backif i still had then cobnle wont be a problem and i build even biger then 5x5 munch biger
