Overwatering
Wet soil plus yellowing, dropping lower leaves points squarely at overwatering — the most common way to lose a baby rubber plant.
Diagnosis
Overwatering
What's happening
Peperomia obtusifolia is semi-succulent: it stores water in its thick stems and glossy leaves, so it needs far less watering than most houseplants. When the soil stays soggy, the fleshy roots can't get oxygen and begin to rot, and the plant sheds its oldest leaves first, which turn soft and uniformly yellow before they fall.
How to fix it
Stop watering and let the soil dry out well. Slip the plant out of its pot and check the roots — healthy ones are firm and pale, so trim any brown, mushy roots with clean scissors and repot into fresh, airy mix in a pot with drainage holes. From now on, only water when the top inch or two feels dry; this plant is far happier slightly dry than wet, and its thick leaves will tell you when it's genuinely thirsty.
What fixes it
- A soil moisture meter — A moisture meter removes the guesswork — only water when it reads dry an inch or two down.
If that doesn't fix it
This is general guidance based on common symptoms; individual plants vary.
