This mod enables a very important capability, to advance the growth state of many kinds of plants. However bonemeal (and mulch, which it also adds) are somewhat expensive, so there is good balance. I, for example, ended up farming corn so that I could mulch it and grow saplings. It adds a great deal of depth to the farming mechanics. I use the farming redo mod, and these two mods work well together.

You can craft bonemeal from player bones (created when you die). I wouldn't call that balanced.
