How to propagate Polyscias balfouriana by cuttings? These key points you need to master
Polyscias balfouriana is native to the Pacific Islands, and it is not difficult to cultivate artificially. Because its leaves are bright and variable, it has become a very popular foliage plant in recent years. Artificial propagation of Polyscias balfouriana can be done by cuttings. The editor will briefly introduce it for you.
Polyscias balfouriana
For propagation of Polyscias balfouriana, cut 1- to 2-year-old branches for cuttings. There is no strict requirement for the choice of growing medium, but drainage must be good. It can be done in both spring and autumn, but spring cuttings give better results. From March to April, cut 10-15 cm leafy sections, keep only 2-3 leaves at the tip, and make the lower cut preferably 0.2 cm below a node. Soak in 500 ppm indolebutyric acid or No. 1 ABT rooting solution for 10 seconds, then insert into a sand bed or vermiculite. For small numbers of cuttings, a wide-mouthed flower pot filled with vermiculite can serve as the cutting bed. After watering thoroughly, cover with plastic film to retain moisture, maintain the optimum rooting temperature of 25-30°C, and provide 40-50% shading; roots will form in 20-30 days. After the cuttings sprout new buds, transplant them into pots.
From May to June, choose robustly growing stems and perform ring barking 20-25 cm from the top. The width of the bark removed should be about 2-3 times the stem diameter. Wrap the ring-barked area with peat soil or mud, knead it into a soil ball, and bind it tightly on the outside with plastic film, leaving an opening at the top for water. If the stem is relatively thin and cannot support the soil ball, insert a bamboo pole as support, tie the soil ball against the bamboo pole, and keep the soil ball moist at all times; roots will form after 2 months. You can also buy lignified stems specially sold for cuttings at flower markets and use them for cuttings, which also root easily.

Cultivation and management of Polyscias
Polyscias (scientific name: Polyscias guifoylei Bailey), also known as: round-leaf Polyscias, round-leaf Panax, is an evergreen shrub in the Araliaceae family. Native to the Pacific Islands. The plant height is 1-3 m, with slender side branches and prominent lenticels on the branches. Leaves alternate, odd-pinnately compound, leaflets in 3-4 pairs, opposite, elliptical or oblong, with serrate margins; the green leaves often have white spots. Umbellate inflorescences, flowers small. Pale white-green. Mainly used for potted plants, garden trees, and hedges. Contact with its sap may cause a red rash; when it touches the mouth, it can sometimes cause swelling and pain that makes swallowing impossible. Cultivation methods:Cuttings can be done in both spring and autumn, but spring cuttings give better results. From March to April, cut 10-15 cm leafy sections, keep only 2-3 leaves at the tip, and make the lower cut preferably 0.2 cm below a node. Soak in 500 ppm indolebutyric acid or No. 1 ABT rooting solution for 10 seconds, then insert into a sand bed or vermiculite. For small numbers of cuttings, a wide-mouthed flower pot filled with vermiculite can serve as the cutting bed. After watering thoroughly, cover with plastic film to retain moisture, maintain the optimum rooting temperature of 25-30°C, and provide 40-50% shading; roots will form in 20-30 days. After the cuttings sprout new buds, transplant them into pots.
Layering From May to June, choose robustly growing stems and perform ring barking 20-25 cm from the top. The width of the bark removed should be about 2-3 times the stem diameter. Wrap the ring-barked area with peat soil or mud, knead it into a soil ball, and bind it tightly on the outside with plastic film, leaving an opening at the top for water. If the stem is relatively thin and cannot support the soil ball, insert a bamboo pole as support, tie the soil ball against the bamboo pole, and keep the soil ball moist at all times; roots will form after 2 months. Clump-planted plants in the ground can also be propagated by ground layering.
Cultivation points: It likes a high-temperature environment and is not very cold-tolerant; it requires bright light, but is also fairly shade-tolerant and avoids direct sun exposure; it likes moisture and is also fairly drought-tolerant, but avoids waterlogging.
Temperature Its optimum growing temperature is 15-30°C, of which it can be kept at 20-30°C from April to October, and at 13-20°C from October to April of the following year. Beautiful plants are usually a bit delicate, and Polyscias is the same. Its variegated-leaf varieties are less cold-resistant. In general, even for ordinary pure green-leaf varieties, the room temperature in winter should be maintained at no lower than 10°C. When the summer temperature reaches above 32°C, it should not be left to its own devices either. For mass production, shade frames should be set up; for home display, it should be placed in a cool place and water sprayed around it to lower the temperature, creating a cool micro-environment relatively close to its native conditions. In late autumn and early winter, when the temperature drops to 15°C, it should be moved indoors promptly to prevent the plant from suffering cold damage. In winter, if the room temperature can be maintained above 20°C, its stems and leaves will continue to grow; if the temperature is not high, the plant stops growing and enters a semi-dormant state.
Light Taking Polyscias balfouriana as an example, it needs bright light. Insufficient light easily causes leggy stems and leaves, dull leaf color, and fading of markings, but at the same time it avoids strong direct sunlight, especially in early summer after a long rainy period when the sky first clears, to prevent the leaves from being scorched. For home potting, it can usually be placed in a well-ventilated spot near a south-facing window; in summer it can be placed in front of a north- or east-facing window; in winter it should be placed in a brighter spot indoors. For production cultivation, from mid-spring to mid-autumn, it should be placed under a shade frame, with 40-60% shading according to light intensity and duration. In short, it grows most vigorously in an environment with partial light and bright scattered light.
Water Potted Polyscias likes a relatively moist soil and air environment. During the growing season, there must be a sufficient water supply. Water after the surface of the potting soil dries; it does not matter if the soil is slightly dry, but do not water too much, to avoid water accumulation and root rot. In midsummer when the temperature is relatively high, in addition to sufficient watering, it is also necessary to spray the leaf surface once a day, which can both keep the leaves clean and glossy and raise the air humidity around the plant. In late autumn and early winter, when the temperature drops below 15°C, watering should be controlled. In winter, watering should be reduced, or spraying can replace watering, keeping the potting soil slightly moist and a little dry, but when spraying the leaf surface, pay attention to making the water temperature basically consistent with room temperature.
Soil The best is loose, fertile, well-drained sandy loam, providing it with a loose, moist, and fertile soil environment. For potting soil, mix 4 parts leaf mold, 4 parts garden soil, 2 parts sand, and a small amount of decomposed cake fertilizer powder or bone meal. During the growing season, combined with fertilizing, loosen the soil of the potted plant once a month, so that the potting soil remains well aerated for a long time, avoiding root rot caused by soil compaction. For plants in the open ground or under shade frames, during the plum rain season or continuous rainy weather, inspections should be strengthened. If water accumulation is found in the pot, it should be poured out promptly and the soil replaced, so as to avoid leaf drop or root rot. In general, replace the soil once every two years in spring.
Fertilizing Polyscias balfouriana and others require sufficient fertilizer. During the vigorous growth period from April to June, apply a dilute cake fertilizer solution once a month, or use low-concentration decomposed poultry manure solution, but organic fertilizer must not adhere to the leaf surface. Fertilizing can be scheduled after loosening the soil and pruning and pinching, or before rain. After applying organic fertilizer, it is best to rinse the leaf surface once with water. For home potting, a mixed solution of 0.2% urea and 0.1% potassium dihydrogen phosphate can be applied, or a small amount of multi-element slow-release compound fertilizer granules can be spread or buried on the surface of the potting soil. After mid-autumn, stop applying nitrogen fertilizer and apply 1-2 additional phosphorus and potassium fertilizers to increase the plant's cold resistance and help it overwinter smoothly. After entering winter, the plant has stopped growing, so fertilizing should be stopped to avoid damaging the roots.
