Peperomia is a huge and wonderfully varied genus, and the plants sold under the name look so different from one another that people are often surprised they are related. There is the watermelon peperomia with its silver-striped leaves, the ripple peperomia with deeply puckered foliage, the trailing string of turtles, and the upright baby rubber plant with thick glossy leaves. What they have in common is compact size, semi-succulent leaves and a very relaxed attitude to being looked after.
There are well over a thousand species in the genus. Most come from the tropical Americas, particularly Central and South America, with others in Africa and Asia. Many grow as epiphytes on tree trunks and mossy branches, or in shallow pockets of leaf litter on rocks, rather than in deep soil. That is why they have small root systems, thick water storing leaves and a real dislike of heavy, wet compost.
Their small size makes them ideal for desks, shelves and windowsills where a Monstera would never fit.
Peperomia does best in bright, indirect light. A position near an east facing window, or a little back from a south or west facing one, suits most varieties well.
Keep it out of strong direct sun, which scorches those fleshy leaves and fades the markings. In light that is too low, a Peperomia becomes leggy, with long bare stems and leaves spaced far apart, and the variegated and silver-patterned types lose their contrast. The more heavily variegated the variety, the more light it needs to look its best.
Let the top half of the compost dry out before watering. In spring and summer that is usually once every one to two weeks, and in winter every three to four weeks.
Those thick leaves are full of stored water, so Peperomia is genuinely drought tolerant and far happier slightly dry than slightly too wet. The leaves will go a little soft and limp when the plant is thirsty, and firm up again within a day of a good drink. Water thoroughly until it runs from the drainage holes, then let the pot drain completely. Use a small pot with a light, free-draining mix, because a large pot full of wet compost around such a small root system is the fastest route to rot.
Peperomia is comfortable at 40% to 50% humidity, which covers most homes without any help from you.
Although many species come from humid tropical forest, they live on tree bark and rocky ledges where conditions dry out quickly, and their thick leaves are built to hold moisture in. That makes them far less demanding than thin-leaved tropicals. Higher humidity does encourage faster growth if you can offer it, and the trailing types in particular enjoy a bathroom, but there is no need for a humidifier or a pebble tray.
Peperomia grows best between 18°C and 26°C and is happy at ordinary room temperature.
The lowest temperature it can withstand is around 10°C. Below that the leaves develop soft dark patches and drop, and cold combined with wet compost will rot the stems quickly. Keep it away from cold windowsills in winter, which is easy to forget with a small plant that naturally ends up sitting on one.
Peperomia is one of the most rewarding plants to propagate because many varieties will grow a whole new plant from a single leaf.
For leaf cuttings, pick a healthy leaf and cut it off with 2 to 3 cm of its stalk attached. Push the stalk into damp, free-draining compost so the base of the leaf sits just above the surface. Keep it warm, bright and lightly moist, and cover it loosely with a clear bag or propagator lid to hold humidity. A tiny new plant appears at the base of the stalk within four to eight weeks. Large-leaved types like the watermelon peperomia can even be cut in half across the leaf and the cut edge pushed into compost.
For stem cuttings, which work well on the trailing and upright types, cut a section of stem with two or three leaves just below a node, remove the lowest leaf and root it in water or damp compost. Roots usually appear within two to four weeks.
Overwatering is by far the most common reason, and with this plant it happens fast. Yellow leaves that feel soft and limp, leaves dropping off at a touch, or stems going black and mushy at soil level all point to compost that has stayed too wet. Stop watering immediately and let it dry right out. If the base of the plant has already gone soft, take cuttings from the healthy top growth straight away, because that is often the only part you can save.
Check the other possibilities too. Yellow leaves that are also wrinkled and thin mean the plant has been left dry too long, so give it a thorough soak. Bleached yellow leaves with dry brown patches mean too much direct sun. A batch of yellow leaves after a cold snap points to chill damage. And the occasional oldest leaf at the base yellowing and dropping while the plant keeps producing new growth is nothing to worry about.
The simplest way to keep a Peperomia healthy is to under pot it and under water it. Use a small pot with drainage holes and a gritty, free draining mix, water only when the top half is dry, feed at half strength every six weeks or so in spring and summer, and repot only every two or three years.
