Hi all, I'm new to Minecraft modding and using Forge but i gotta say I'm loving it. I'm making a custom biome and have a custom dirt block as my top block, just wondering if Forge has some way of enabling the vanilla saplings to be planted on my custom dirt ... without turning this into a core mod.

Look at

public boolean canSustainPlant(World world, int x, int y, int z, ForgeDirection direction, IPlantable plant)

    in Block.

Override in your dirt block if needed.

Thanks, exactly what i needed 

I figured this out myself for my custom sapling but the issue I have now is that I cannot get my custon sapling or a vanilla sapling to grow using bonemeal, when I apply the bone meal there is no particle affect showing usage and no matter how many I try to apply no trees grow. I do have a custon Bonemeal event, and it will grow my custom sapling on standard soil.
