I'm looking for a plugin that will not allow harvesting other people's plants, regardless of whether they grow in beds or on the ground. If the player is not the owner or is not authorized in the cabinet, he will not be able to harvest them. The PlanterBoxDefender plugin is not suitable for this reason. Thank you

Your best possible course of action would be to always ask the Developer of a plugin you would consider, if only it had "this option" The Plugin Support for Planter Box Defender.  Pose the question to @Kaucsenta, and ask if this is possible.  Otherwise this post should have originated in https://umod.org/community/plugin-requests
