Mass Cane (Dracaena fragrans) Green Trunk Algae: Wait to Repot

Situation

Mass cane in 12-inch pot, 3 trunks, 2 show green on bark. Using self-watering globes. Owner plans spring repot.

Advice

  • Spring repot is fine.
  • Green on bark is likely algae/moss from moisture—harmless.
  • Self-watering globes risk overwatering; monitor soil moisture manually.
  • If green is fuzzy or spreading, send close-up photo.
