Cast Iron Plant brown tips

Slow-growing cast iron plants can keep leaves for a long time. A brown point on an old leaf may record past damage even when current care is sound.

If newer leaves are also affected

Check for a root ball left dry for long stretches, hot airflow, or salt deposits after heavy feeding. Water thoroughly when the upper mix dries and empty runoff. Flush accumulated salts only from a freely draining pot with healthy roots.

Trim dry tips if desired, leaving a narrow dead margin. Keep the rest of the blade: replacing whole leaves takes this plant much longer than replacing foliage on a fast-growing vine.
