DanTdm! The Experience tree is awesome! What it does is that at night, it drops xp orbs and bottles! The tree is also Super Huge! Also, try planting it on normal grass not long grass because I think that is why it didn't grow on long grass because it is modded. The seed is supposed to plant a sapling that grows quickly. You definitely need to grow it! Leave a like so that DanTDM can see this!
