Rubber Plant brown spots

A dry fixed patch can follow sun exposure or a bruise. Corky bumps may be related to edema, while wet-looking spots that expand need a closer disease check. Appearance alone cannot identify a pathogen.

Follow the active sign

Filter intense sun if damage is limited to newly exposed leaves. For expanding lesions, separate the plant and keep foliage dry. Photograph changes and seek a plant diagnostic service if they spread rapidly.

Inspect undersides and stems for pests and sticky residue. If spotting also comes with wilt or yellowing, check the root ball and drainage. Use the brown spots comparison to distinguish these patterns.
