How to Propagate Chinese Evergreen? A Detailed Guide to Common Propagation Methods
Division method:
Generally carried out in February-March in conjunction with repotting, dividing clustered plants into several plants with roots and replanting them separately. They can also be divided and planted in other seasons. After division, they can be divided again after three years.
Sowing method:
Sowing is generally carried out in March-April. Sow in a flower pot filled with culture soil, water, then temporarily place in a shaded area, keep moist, and at 25-30 degrees, germination occurs in about 25 days. During the growing season, sufficient water supply is needed; in midsummer, spray water on the leaf surface every morning and evening; in winter, stem and leaf growth slows down, so water should be controlled and the pot soil should not be too wet. In southern regions, it is often placed in semi-shade for maintenance in summer. From May to October, during the period of vigorous stem and leaf growth, fertilize once every half month. When moved indoors in winter, if the leaves turn yellow, apply one additional application of diluted nitrogen fertilizer. After several years of growth, the mother plant often becomes prostrate with a poor appearance and should be re-propagated by cuttings for renewal.
Cutting method:
Can be done in May-June or September. Select strong young stems, cut a 12-15 cm section from the top downward, cut the lower part at 0.61 cm below the node, coat the cut with plant ash to prevent rot, dry in the shade, then insert into clean plain sand, with a planting depth of 45 cm, place in a concealed area, always keep the pot soil moist, and maintain 80% air humidity. After 34 weeks of insertion, roots can form, and when roots grow to 23 cm, they can be planted in pots.

Propagation Methods of Chinese Evergreen
Chinese Evergreen, also known as Chinese Evergreen, Guangdong Evergreen, Cantonese Evergreen, Large-leaf Evergreen, and Well Grass. Latin name: Aglaonema spp. It is a plant of the Aglaonema genus in the Araceae family. Commonly propagated by division and cuttings.Division propagation: Carried out during spring repotting. Remove the plant from the pot, cut the rhizome at the stem base, coat with plant ash to prevent rot, or leave for half a day until the cut dries before potting. After planting, do not water excessively.
Cutting propagation: Best in spring and summer. Select 12-15 cm long, sturdy young stems as cuttings, keep the top 2 leaves, insert into a sand bed, maintain high air humidity, room temperature 25-30°C, roots form 20-28 days after insertion. Water propagation can also be used; the cuttings can be slightly longer, preferably 15-20 cm, inserted directly into a glass bottle filled with clean water, changing the water every 2 days, new roots grow in about 15-20 days, and when roots are 3-4 cm long, pot them.
At the same time, in industrial production, Chinese Evergreen stem nodes are cut into small sections, but must include the internodes, wrapped with fresh sphagnum moss and placed in a seedling box, maintaining a room temperature of 20-25°C, roots and shoots emerge from the stem nodes in about 20-25 days. In its place of origin, it is propagated by seeds, requiring high temperatures of 25-28°C for germination, with a high germination rate.

[Chinese Evergreen Propagation] Cuttings, division, sowing, etc.
(1) Cuttings: Carried out from April to September. Cut 10-15 cm long sturdy stem sections as cuttings. Keep the top 2 leaves, coat the cut with plant ash, let dry slightly, then insert into the seedling bed. After insertion, maintain high air relative humidity and a temperature of about 15°C; roots and survival occur after 15-20 days. Stem sections without leaves can also be used as cutting material, but rooting and sprouting are slightly slower than with leafy tips. It is also very suitable for water propagation; simply insert the cut branches into water, and roots will emerge in just over 10 days.
(2) Division: Often carried out in spring in conjunction with repotting. After removing from the pot and cleaning off the soil, use a sharp knife to cut the plant into several clumps from the underground rhizome between the clustered stems, coat the cut with plant ash for preservation, or place in a cool place for half a day, and plant separately after the wound dries.
(3) Sowing: Best carried out under high temperature conditions of 25-28°C to maintain a high germination rate.
[Key Points for Cultivating Chinese Evergreen]
(1) Temperature: Prefers warmth, the most suitable temperature for growth is 20-30 degrees. Relatively cold-tolerant, it is one of the most cold-tolerant species among Araceae foliage plants. As long as the temperature is above 0 degrees, it can safely overwinter. Not very tolerant of high temperatures; high temperature environments above 35 degrees are not conducive to plant growth, so measures such as shading, environmental spraying, and enhanced ventilation should be taken in summer to lower the temperature.
(2) Light: Prefers semi-shade environment, avoid strong direct sunlight; even short-term strong direct light will cause leaf surface burns, turning white and scorched. Excessive light will also cause leaves to turn yellow and smaller, and lose luster. From May to September, shading should be applied, blocking about 50% of sunlight. Under semi-shade conditions, leaves are large and glossy, and appear a beautiful tender green. Although very shade-tolerant, even in too dark places it will not become leggy, but its growth condition is inferior to plants under semi-shade conditions. At other times, it is best to provide sufficient sunlight.
(3) Watering: Prefers moist soil environment, very tolerant of waterlogging but not drought. During the growing period, sufficient water should be supplied to ensure the pot soil does not dry out, but waterlogging and excessive wetness should be avoided; watering should follow "alternating dry and wet with a tendency toward wet." In winter, watering should be controlled, only keeping the pot soil slightly moist. When temperatures are low and the pot soil is too wet, leaves will turn yellow, and root rot is likely, even leading to plant death in severe cases.
(4) Environmental humidity: Prefers a humid environment. During the growing season, especially when it is sunny and dry, water should be sprayed frequently on the plant and surroundings to maintain a humid environment, which is beneficial for lush plant growth and makes the branches and leaves more vibrant and fresh green. When the air is dry, leaves will turn yellow, lose luster, and develop scorched edges.
(5) Fertilization: Prefers fertilizer; sufficient fertilizer can make leaves large and glossy, stems sturdy, and tillering vigorous. When fertilizer is lacking, leaves become smaller, plant growth is poor, and in severe cases, the lower leaves of the plant turn yellow and fall off. During growth, apply a nitrogen-based fertilizer once every 15-20 days. After autumn, if the plant grows vigorously, stop applying nitrogen fertilizer and appropriately increase phosphorus and potassium fertilizer to help improve the plant's cold resistance. Stop fertilizing in winter.
(6) Repotting: Usually repot once every 1-2 years. Prefers loose, fertile, well-drained slightly acidic sandy loam, avoid using heavy clay soil. If drainage is poor, plant growth will be poor in mild cases, and root rot in severe cases. The substrate can be made from materials such as leaf mold, garden soil, perlite, or rice husk ash. After many years of growth, old plants will become prostrate and the plant shape will be unattractive, so cutting propagation should be carried out for renewal.
(7) Pest and disease control: During high temperature and dryness, red spider mites are prone to occur, and attention should be paid to control. Other pests and diseases include blight, leaf blight, mosaic virus, leaf spot, anthracnose, root-knot nematodes, etc.
