An idea about rejuvenation of trellis plants.
There are a plant, that not dissapear after harvesting (pepper, grape, hops) - it will no grow in quality after harvest.
The idea is next - you can destroy a plant, just rip it. If you didnt plant something to that tile, and not destroy trellis - this plant will sprout from the root, with better quality.
Like grape rejuvenation in real life.
