Ripple peperomia: root rot
Does it have root rot, and can it be saved?
On ripple peperomia, the likeliest cause is no drainage hole, or soil too heavy. Water sits on the surface, or the decorative pot has no hole and the inner pot is standing in what drained out.
- 1No drainage hole, or soil too heavy
Ranked here because its mix should be two parts peat-free potting soil, one part perlite — standard potting compost holds far too much water for it.
How to tell. Water sits on the surface, or the decorative pot has no hole and the inner pot is standing in what drained out.
What to do. Drill the pot or use a liner you can lift out. This species wants two parts peat-free potting soil, one part perlite.
- 2Watered faster than it dries
Ranked here because the commonest way houseplants die indoors.
How to tell. Soil damp days after watering, yellowing lower leaves, and a sour smell at the drainage hole. Roots brown and slimy rather than pale and firm.
What to do. Unpot, cut every soft root back to firm tissue, repot into fresh dry gritty mix, and do not water for a week. Do not fertilise a damaged root system.
- 3Pot much larger than the root ball
How to tell. A small plant in a large pot, where the soil away from the roots stays wet for a week or more.
What to do. Pot down. A pot an inch or two wider than the root ball dries at a rate the plant can keep up with.
- 4Cold and wet together
How to tell. Rot appearing in winter, on a plant near a cold window or in an unheated room, watered on a summer schedule.
What to do. Keep it above 60°F and cut watering back hard in winter. Cold roots cannot drink.
Why that order, for this plant
The ranking above is not a generic list. It is computed from this species' own record — a watering interval of 7–14 days, a tropical understory origin, a humidity floor of 40%, and a light range from low to bright-indirect. Change those figures and the order changes with them.
That is the whole point of a per-species page. Root rot on a plant watered every three days and root rot on one watered every three weeks almost never have the same cause, and a list that ranks them identically is worth nothing to either owner. You can check the reasoning against the care fields on the species entry, which is where these numbers come from.
No percentages appear on this page. We have not run a grower survey, and a confident-sounding figure with no dataset behind it is worse than none. Order and distinguishing tests are what we can honestly give.

Watch for mealybugs, spider mites and white fly. Leaf spots may occur. Susceptible to rot if soils are kept too moist. Wetness and cold winter temperatures must be avoided.
