Bonsai Trees Upgrades & Automatic Harvesting

The four upgrade slots change what the pot does when a tree finishes growing:

• Cutting tools (axes) - REQUIRED for automatic harvesting. With a cutting tool installed, the pot chops the grown tree by itself and drops go to the output slots. Without one, the pot just holds the grown tree until you break it manually.
• Silk-touch tools - a cutting tool enchanted with Silk Touch harvests blocks intact where the tree supports it.
• Fortune-style boosts - fortune-enchanted tools increase drop amounts, exactly as they would on real blocks.
• Hoppers - hopper upgrades add item-transfer behavior; a plain hopper block under the pot also extracts the output slots.
• Bee hives - bee hive upgrades add their products to the harvest.

Tools in the upgrade slots take durability as they chop, so unbreakable or well-enchanted tools last accordingly.
