Understanding Bark Formation on Rubber Plant Stems

Bark on Lower Stems Is Normal Aging

Green stems become woody/barky over time—this is natural, not a problem.

But Repotting Was Risky

Unnecessary repotting is the #1 cause of plant failure. Risks you took:

• Pot too large → excess moisture.
• Root hairs damaged (they do most absorption).
• New soil mismatch with old.
• Drainage material at bottom (harmful myth).

Any issues in coming months likely trace to this repotting. Monitor closely; avoid further disturbance.
