Small-Leaf Peperomia problems — and how to fix them
Small-Leaf Peperomia (Peperomia parvifolia) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root rot from overwatering
Its lithophytic origins mean it is among the more drought-tolerant peperomias but consequently least tolerant of wet feet; the small root system rots quickly in soggy compost — use a very free-draining mix and a terracotta pot to aid evaporation.
Powdery mildew
Dense, compact foliage with limited air movement is prone to powdery mildew in humid, stagnant conditions; space plants to allow airflow, avoid wetting the leaves, and treat early signs with a diluted bicarbonate of soda spray or a fungicide approved for ornamental plants.
