How to Grow Pilea peperomioides: Cultivation Methods and Precautions
The leaves of Pilea peperomioides have a rather peculiar shape, looking like a small mirror, which is why people gave it this name. Generally, if you want to grow Pilea peperomioides well, temperature conditions are one of the main requirements for growing it. So next, let's take a look at what other precautions, besides temperature conditions, need our attention.
How to Grow Pilea peperomioides
First, we need to know its growth habits. It is a plant that prefers a warm, humid environment, with an ideal temperature of 15°C to 25°C. In spring and autumn, when the climate is warm, it grows relatively vigorously. In summer, when the air is dry, it grows slowly, so it can be placed in a cool location. In winter, it is not cold-tolerant, and the temperature must not drop below 10°C. If exposed to prolonged low temperatures, it can easily die, so it can be placed in a warm greenhouse.
Cultivation Methods and Precautions for Pilea peperomioides
I. Cultivation Methods
1. For propagation and cultivation, choose loose, fertile, sandy loam rich in humus. You can mix garden soil, leaf mold, and river sand in equal parts. Keep the potting soil moist at all times. During the growing season, apply dilute liquid fertilizer once every half month. Some propagate by sowing seeds, but division or cutting can generally be used. March to May each year is the best time for division and cutting.
Pilea peperomioides is dioecious, with a flowering period in April and a fruiting period from May to June. In Yunnan, it can be propagated by sowing seeds; the seeds of Pilea peperomioides are tiny, so they should not be sown deep, as deep sowing makes it difficult for seedlings to emerge. Pilea peperomioides is relatively cold-tolerant and can overwinter safely outdoors in the south. It prefers shade and should be cared for in a location with shading conditions. Its ideal growth temperature is around 15°C, and it also grows well in a well-lit greenhouse. It is generally used as a potted ornamental plant.
When planting, use humus soil mixed with sand that drains well; line the bottom of the pot with tile pieces to facilitate drainage. Pilea peperomioides is very shade-tolerant; as long as there is enough light to read an ordinary newspaper, it can grow, so it is very suitable for indoor potting at home. It prefers a warm, humid environment. Below -4°C, chilling damage occurs, the leaves lose their luster, or even fall off.
2. For leaf cuttings, you can refer to the leaf-cutting method for begonias. You can also cut the stem into small sections of about 3 cm for cuttings. If the leaves fall off due to freezing damage, but the stem is undamaged, you can manage it according to routine winter care, and in the spring of the following year it can still produce leaves and become a plant again. In summer, do not place it in direct strong sunlight. Throughout spring and summer is the vigorous growth period of Pilea peperomioides, so strengthen fertilizer and water management, and frequently water or spray the leaves with a 0.1%-0.5% potassium dihydrogen phosphate solution. During spring, supplement with a small amount of nitrogen fertilizer from time to time, and in summer apply as little or no nitrogen fertilizer as possible.
Throughout the growing period, the pot should mainly be kept moist. In winter, it can be relatively drier, but dryness must not occur, otherwise the leaves are prone to withering and turning black. In dry seasons, frequently spray water on the leaves and surroundings to create a humid micro-environment.
II. Precautions
1. Choose loose, fertile, sandy loam rich in humus. You can mix garden soil, leaf mold, and river sand in equal parts.
2. Keep the potting soil moist at all times, but avoid waterlogging, to prevent leaf discoloration, wilting, or even stem rot. Water according to the principle of watering when dry and letting it dry somewhat between waterings. To maintain air humidity, you can frequently spray the leaves.
3. It prefers bright indirect light and avoids harsh sun exposure, to prevent scorching the leaves and turning the leaf color yellow. From late autumn to the following spring, it can receive more sunlight.
4. It prefers warmth. The ideal growth temperature is 15°C to 20°C, and the minimum winter temperature is 10°C. When summer temperatures exceed 30°C, growth stagnation occurs, and leaves easily fall off. In particular, note that a sudden drop in temperature can cause the leaves and stems to discolor, with some falling off.
5. During the growing season, apply dilute liquid fertilizer once every half month, but note that too much nitrogen fertilizer can cause leggy leaf growth and lodging of the plant, and concentrated fertilizer or raw fertilizer can cause root rot or even death of the plant.
Main Value of Pilea peperomioides
1. Ornamental
The thick, nearly round fleshy leaves of Pilea peperomioides, with leaf stalks attached in a peltate manner, closely resemble the mirror in which ancient immortals looked at their faces. The leaves are dark green and glossy, and at the upper center of the leaf, where the leaf stalk attaches, there is a golden-yellow round dot. Radiating leaf veins extend from the center to all sides, with clear lines like golden threads, showing a touch of elegant, high-end refinement.
Since Pilea peperomioides was introduced to Europe in the early 20th century, in countries such as the United Kingdom, Sweden, and Norway, it has been introduced and cultivated by botanical gardens and gardening enthusiasts, and is regarded as a treasure among indoor foliage flowers, deeply loved by people. Its leaf shape is peculiar, its posture beautiful. It grows quickly. It is easy to propagate, suitable for greenhouse, courtyard, and indoor cultivation, and is a relatively ideal foliage plant worth promoting, as well as a good material for making and decorating bonsai.
3. Air purification
The respiration of Pilea peperomioides can absorb waste gases from the air and then convert them into conventional gases harmless to humans. Pilea peperomioides can also absorb a certain amount of radiation, preventing radiation from harming the human body. Placing a pot of Pilea peperomioides at home is not only pleasing to the eye, but even the air becomes fresher! Leaf after leaf sways in the wind and also absorbs dust from the air. It is truly a treasure that is both good-looking and useful! No wonder Europeans regard Pilea peperomioides as a treasure.
3. Medicinal
Pilea peperomioides is a very important medicinal material in western Yunnan. In the hands of the Dai people, it can be a good medicine for reducing swelling and relieving pain, a detoxifying marvel, and can also set tendons and bones. It is simply the dearest plant one could encounter when surviving in the wild. For red, swollen, inflamed skin, Pilea peperomioides can effectively reduce inflammation and detoxify. It is recorded in the Dian Yao Lu.
Differences Between Pennywort and Pilea peperomioides
1. Different appearance
The stems of pennywort are thin and long, and the leaves are roundly peltate, with dense T-shaped hairs attached to the back, covering the entire margin. However, its leaves are relatively small, with shallowly split veins, and when rubbed by hand they give off a celery fragrance. In summer and autumn, it produces yellow-green flowers.
Pilea peperomioides is a perennial succulent herbaceous plant. Its leaves are dark green, plump and glossy, and its round, chubby appearance is extremely lovable. Where it joins the leaf stalk, there is also a golden round dot, and the leaf veins naturally spread radially from the center to all sides. Seen from a distance, it closely resembles an ancient mirror.
2. Different growing environment
Pennywort likes humid environments and can survive both in water and on land. It mostly grows in wetlands or in artificially maintained aquariums. It is not suitable for growing in direct sunlight; partial sun or shady locations can satisfy its sunlight needs.
Pilea peperomioides is suitable for growing in warm, humid environments. It prefers loose, well-drained loam rich in organic matter and can only survive in soil in semi-shaded locations, unlike pennywort, which can grow both aquatically and terrestrially. Its ideal growth room temperature is 16 to 20°C, and if it is below -4°C, chilling damage occurs.
3. Different value
Pennywort is non-toxic, and the whole leaf can be used as medicine. It has effects such as reducing internal heat and promoting urination, clearing heat and detoxifying, and reducing swelling. It can also be used for conditions such as damp-heat jaundice, heatstroke diarrhea, sand strangury and blood strangury, carbuncle swelling and sore poison, and traumatic injuries.
Pilea peperomioides can not only serve as an ornamental flower, but also has extremely high medicinal value. Its nature is "sweet and bitter" and "cool in nature." It can be used as a raw material for clearing heat and detoxifying and for removing blood stasis and reducing swelling. It mainly treats erysipelas and also significantly helps with recovery from fractures and the like.
Pilea peperomioides has multiple effects. Personally, I rather like its air-purifying effect. Placing a pot indoors is not only pleasing to the eye, but also absorbs some of the bad air at home. In particular, it can absorb a certain amount of radiation, which is very beneficial for people who work at computers all day, reducing harm to the body.
