So far i have a biome(with working mob spawns, colors and that stuff) and working logs and leaves for 2 trees(with decay and rotation and all that stuff(loads of copy+paste from BlockNewLog and BlockNewLeaves)).

I cant grow the trees tho, cause i have no idea how i do it.

Now i want to generate one tree everywhere where trees can normally grow(forests,plains and what you have) and the other one only in my own biome...

Update: got some saplings going, but no actual tree growing, just some block you can bonemeal to have some green stars(as i still cant see hth i do actual trees).
