Seeding is a DLC Merc Mission in Xenoblade Chronicles 2. It can be received in the Leftherian Archipelago automatically after clearing the mission Reclamation, obtained after clearing the DLC Quest Cleared of All Charges. The time required to complete this mission is 30 minutes, but it can be reduced down to 7 minutes by dispatching Blades with the "Agronomy" and "Focus" Field Skills.
It uniquely awards more Trust Points than other normal Merc Missions. Completing it will unlock the DLC Merc Mission Growing. It will also restore the Collection Point on the field next to Corinne's House, which is temporarily disabled after accepting the Cleared of All Charges Key Item.
