Growing trees

Change trees that when sapling is planted they change the dirt block underneath into a dirt root block which makes the tree ‘alive’ when it is alive the sapling can grow into a young tree and then eventually a adult tree and then older and have other levels of growth depending on the type of tree. You could get the root out using a hoe or shovel (converting back to regular dirt) and freezing the growth in the current stage. Then you could also maybe use the newly harvested root to craft something new like a basket or new recipes for ladders or vines or mossy blocks.
