About Notch-Tipped Peperomia
Peperomia retusa · also called Notch-tipped peperomia, African peperomia · houseplant
Notch-tipped peperomia is a small, slightly succulent perennial herb native to tropical and southern Africa — from West Africa through East Africa to KwaZulu-Natal in South Africa — where it grows epiphytically on mossy tree trunks and lithophytically on boulders in moist evergreen forest at elevations up to 2,500 m. Its leaves are obovate to elliptic and notably small, reaching only 5–15 cm (2–6 in) in height as a whole plant. The name retusa refers to the notched or shallowly indented leaf tips. As with all peperomias, restraint with water is the key care rule — it prefers to dry slightly between waterings and resents waterlogged conditions. The ASPCA lists Peperomia as non-toxic to cats and dogs.
Growth habit: Tiny, compact, slightly succulent epiphytic or lithophytic perennial herb.
What fertiliser notch-tipped peperomia actually wants — and why
Notch-Tipped Peperomia is an easy, light foliage feeder — a half-strength balanced liquid feed through the growing months keeps it green without forcing weak, sappy growth.
A balanced general houseplant feed (roughly even N-P-K) is exactly right — it is grown for foliage, so steady, moderate nitrogen for healthy leaves is the goal, not a bloom or root formula.
For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for notch-tipped peperomia: match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.
How often to feed notch-tipped peperomia, and which months
Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For notch-tipped peperomia:
Feed monthly from spring through summer with a half-strength balanced liquid fertiliser; withhold fertiliser in autumn and winter as the plant's growth slows significantly. Treat that as monthly between spring through early autumn (roughly March to September); ease off in autumn and stop entirely in the low light of winter.
The dormant-season rule matters more than the exact interval: skip feeding entirely when notch-tipped peperomia is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.
What strength to mix for notch-tipped peperomia
Half strength is the safe default for notch-tipped peperomia — houseplant feeds are formulated strong, and the diluted dose is gentler on the roots while still ample for foliage.
Feeding always goes onto already-damp soil, never dry roots — water notch-tipped peperomia first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the notch-tipped peperomia watering schedule.
Signs you are over-feeding notch-tipped peperomia
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for notch-tipped peperomia:
- Brown, crispy leaf tips and edges with no sign of underwatering.
- A white, crusty salt deposit on the soil surface or pot rim.
- Weak, pale, stretched new growth that flops.
- Lower leaves yellow and drop while the soil is correctly watered.
Signs you are under-feeding notch-tipped peperomia
- Uniformly pale or yellow-green leaves, oldest first.
- Noticeably small new leaves and stalled growth in good light and season.
- A generally tired, lacklustre look despite correct watering and light.
If the symptoms point at watering, light or roots rather than nutrition, the full notch-tipped peperomia care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of notch-tipped peperomia with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
Organic vs synthetic feeds for notch-tipped peperomia
Organic options
A diluted seaweed or worm-casting feed, or fish emulsion if you can tolerate the smell indoors. UK: Westland or Baby Bio Organic, dilute seaweed; US: Espoma Indoor! or Neptune's Harvest fish & seaweed. Slow, gentle and hard to overdo.
Synthetic / liquid feeds
A general-purpose houseplant liquid at half strength — UK: Baby Bio, Westland Houseplant Feed or Phostrogen; US: Miracle-Gro Indoor Plant Food or Schultz. Convenient and fast-acting; the only risk is overdoing it.
Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.

What does over-feeding notch-tipped peperomia look like?
Brown, crispy leaf tips and edges with no sign of underwatering. A white, crusty salt deposit on the soil surface or pot rim. Weak, pale, stretched new growth that flops. Lower leaves yellow and drop while the soil is correctly watered. Feeding notch-tipped peperomia year-round on a fixed schedule, including dark winter months, is the most common mistake — it cannot use the nutrients in low light and the surplus simply burns the roots and crusts the soil.
Should I flush the soil of notch-tipped peperomia?
Flush the pot of notch-tipped peperomia with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
