This mod adds a Foliage regeneration technology that unlocks refoliant capsules, to heal trees damaged by pollution. Works on wild trees as well as trees planted by the agricultural tower in Space Age.

Throwing a refoliant capsule sprays aerosolised fertiliser over a 15-tile radius. Any pollution-damaged trees in this radius will regrow their leaves and have their colour fully restored.

Trees that were already dead on the ground do not regrow.

Refoliant capsules are crafted in assemblers from steel, circuits, water and explosives. Foliage regeneration technology requires Explosives and Chemical science pack research to be unlocked.

Settings

• Refoliant requires going to Gleba (enabled by default, no effect if Space Age is not active): changes technology to require Tree seeding research and crafting recipe uses nutrients instead of explosives
• Regrow foliage instantly (enabled by default): a capsule instantly restores a tree's foliage to maximum. Disabling this option restores only one level per capsule.
• Regrowth damages trees (disabled by default): enabling this option causes capsules to damage trees if they restore foliage, and only restores foliage if a tree is at full health. The effect is to force a cooldown between uses.
