Compost wood or spoilage into artificial grass tiles that consume pollution.
Build Zen Towers for compact wood production on Nauvis or Gleba.
Grow wood in Zen Gardens on any surface.
This mods seems to make it so that seeds can not be planted on Eneas tiles. Specifically Eneas Grass this seems unintended. Enias is a planet mod with Nauvian conditions and a focus on removing pollution so it would be good if you could plant trees there. I can not put down artifical grass either.
