Nine-leaved Orange (Murraya paniculata) Bonsai Care Methods and Daily Management Tips

Murraya paniculata is a subtropical tree species, distributed in the southern and southwestern regions of China. It prefers sunny, warm and humid climates, is slightly shade-tolerant, and fears cold. It is suitable for cultivation in deep, fertile, loose, well-drained soil. It has strong sprouting ability and tolerates pruning well. Young branches have obvious axillary buds, and old branches have many adventitious buds. This characteristic can be used to build up branches and truncate the trunk of Murraya paniculata, promoting a short trunk and dense branches.

Transplanting, repotting and soil changing of Murraya paniculata should be carried out after March in spring, and it is best to do so when daytime and nighttime temperatures are not lower than 15°C. Transplanting and repotting when temperatures are too low can easily cause death; transplanting and repotting when temperatures are too high can easily cause dehydration, affecting root and branch development, and even causing death. When transplanting, it is best to keep a soil ball, or at least keep the soil clinging to the roots. Keep the tree stump fresh, shorten excessively long roots, and cut off useless roots, branches and trunk. When truncating, leave a little extra length. Minimize the time the stump is out of soil to avoid dehydration that affects its survival. After axillary buds and adventitious buds sprout, select appropriate positions, retain appropriate branches and buds, and prune again.

The potting soil can be made from leaf mold mixed with pond mud, decomposed organic fertilizer or bone meal. Pond mud is sun-dried and weathered or manually crushed into granular form, then mixed evenly to form a loose, fertile, well-drained, well-aerated neutral soil. Generally, suburban vegetable garden soil mixed with a small amount of fine sand and rice husk ash can also be used as potting soil after mixing evenly. The potting soil must not cover the roots too high; it should only cover up to the original root level, because Murraya paniculata easily grows multiple layers of roots, which affects the ornamental appearance of the original roots. The drainage hole should be properly covered with tile pieces to avoid water accumulation that affects new root growth.

After new stumps are potted, they should be placed in a cool place for 1 week of care. Spray water mist on the trunk multiple times a day to keep the trunk moist and promote axillary bud sprouting. Keep the potting soil moist but not waterlogged to avoid root rot. After the stump sprouts and roots develop, gradually increase light exposure. Generally, no fertilizer should be applied within 1 month after potting.

For established Murraya paniculata, during spring, summer and autumn, keep the potting soil moist, and water thoroughly whenever the soil surface dries. Also frequently spray water on the trunk and leaves. In northern regions, when the first frost occurs in winter, move it indoors for warm care. Winter room temperature should be kept above 5°C, and watering should be reduced to prevent frost damage. Apply decomposed organic liquid fertilizer 3 to 4 times each year in spring and summer, and add sufficient base fertilizer each year when repotting and changing soil.

Murraya paniculata has strong sprouting ability, so elongated branches must be pruned frequently to maintain the original shape of the established stump.

Common pests of Murraya paniculata include aphids, stem borers, red spider mites, and wax scale insects. Wax scale insects can be controlled by spraying with 40% dimethoate at 800 times dilution, or 50% dichlorvos at 1000 times dilution can be used to spray and kill stem borers, red spider mites, and wax scale insects. When stem borers are found boring into the tree core, a thin iron wire can be used to pierce and kill them.

Potting Process of Murraya paniculata and Precautions for Caring for Murraya paniculata Bonsai

Murraya paniculata bonsai is a highly ornamental plant that has long received widespread attention. So what are the cultivation methods for Murraya paniculata bonsai? I believe everyone would like to know the answer to this question. Through learning about plant cultivation knowledge, we can better integrate it into practical life. So let us take a look together next.

Potting Process

Pot selection: Murraya paniculata is mostly grown in glazed ceramic pots, and those produced in Shiwan, Guangdong are preferred because of their better water permeability. In addition, purple clay pots can also be used. A medium-deep rectangular or oval pot shape is suitable.

Soil: For potted Murraya paniculata in the south, river mud or pond mud is often sun-dried and weathered into fragments before use. Generally, loose and well-aerated leaf mold or garden soil mixed with an appropriate amount of sand and rice husk ash can be used.

Planting: Potting is best done in April to May in spring, and cannot be done during cold periods. When planting, the root system should be filled in with fertile loose soil, and the bottom of the pot should be raised or covered with a layer of vermiculite to facilitate drainage.

Introduction to Murraya paniculata

Murraya paniculata is a plant of the genus Murraya in the Rutaceae family. It resembles the morphology and structure of Aglaia odorata of the genus Aglaia in the Meliaceae family and is often easily confused with it. Both are evergreen shrubs and can sometimes grow into small tree forms. Young branches are cylindrical, grayish-brown on the surface, with longitudinal wrinkles, tough in texture, not easy to break, and with an uneven cross-section. Pinnately compound leaves have leaflets; the leaflets are obovate or nearly rhombic, with blunt, acute or concave tips, slightly oblique bases, and entire margins; yellow-green, thinly leathery. When observed in sunlight, the upper surface of the leaves has transparent glandular dots. The petiolules are short or nearly absent, and the lower part is sometimes covered with fine hairs. They are ovate, spoon-shaped obovate or nearly rhombic, with entire margins, dark green and glossy. Crushing the leaves releases a citrus fragrance. The flowers are cymes, white in color. The berries are nearly spherical, fleshy and red, with fragrant fruit, a bitter and pungent taste, a numbing sensation on the tongue, and mucus.

Murraya paniculata is also known as Stone Chili, Nine Autumn Fragrance, Nine Tree Fragrance, Seven Mile Fragrance, Thousand Mile Fragrance, Ten Thousand Mile Fragrance, Mountain-crossing Fragrance, Golden Osmanthus, Mountain Yellow Skin, Thousand Eyes and Moon Orange. It is mainly distributed in Yunnan, Guizhou, Hunan, Guangdong, Guangxi, Fujian, Taiwan, China, Hainan and other places in China, as well as some other tropical and subtropical regions of Asia. Its plant form is graceful, its branches and leaves are elegant, and its flowers are strongly fragrant.

The following points should be noted when caring for Murraya paniculata bonsai:

1. Murraya paniculata bonsai needs to be repotted once every 2 to 3 years, and this should be done in April or May. When repotting, prune rotten roots, old roots and overly dense roots. When repotting Murraya paniculata, 50%-70% of the old potting soil around the soil ball needs to be removed and replaced with new soil.

2. Organic fertilizer and cake fertilizer used for Murraya paniculata bonsai must be fully decomposed before use; otherwise, fermentation in the potting soil can easily burn the roots. Liquid fertilizer should not be too concentrated and must be diluted before use; otherwise, fertilizer damage can easily occur.

3. Murraya paniculata bonsai has relatively few pests and diseases, but longhorn beetles, aphids and scale insects sometimes occur. When pests are found, they can be caught manually, or lime sulfur mixture can be used for prevention and spraying.

4. In addition, Murraya paniculata has strong sprouting ability, so crossing branches, overlapping branches, dead branches, and diseased or pest-infested branches need to be pruned continuously and frequently.

The above is the relevant introduction in this article. I believe that after reading it, you have a simple understanding of this. If needed, you can continue to follow No.1 Home Network to learn more information.

Murraya paniculata Bonsai, Cultivation and Care of Murraya paniculata Bonsai

Murraya paniculata is a shrub or small tree plant of the genus Murraya in the Rutaceae family. Its flowering period is in autumn; the white flowers are large but few, fragrant, and the fruit is fleshy and red. Murraya paniculata prefers a warm, humid climate and sunlight, and is also relatively tolerant of shade and drought. It has strong sprouting ability and tolerates pruning. It grows better in fertile, loose, well-drained neutral or calcareous soil. Its bonsai cultivation methods are as follows:

Transplanting is usually carried out in March—April in spring. The potting soil is prepared by mixing highly aerated garden soil with a small amount of sand and rice husk ash. Light yellow, gray-brown and blue glazed ceramic pots are commonly used.

Murraya paniculata is suitable for making into large natural-style bonsai such as straight-trunk style and slanting-trunk style. Murraya paniculata is suitable for styling by pruning, and its trunk can be slightly wired and bent before pruning. The pruning period is best in April-May in spring. The “branch-building and trunk-truncation method” is generally adopted, that is, when the main branches of the trunk are cultivated to a suitable thickness, a section is cut off from each branch and trunk. After years of pruning, the branches and trunk can achieve a naturally winding, vigorous effect, with well-balanced density, full of pictorial charm.

Murraya paniculata bonsai should not be placed indoors in insufficient light for a long time. It should be placed in partial shade. In summer, attention must be paid to preventing exposure to intense sunlight, and in winter it needs to be placed in a greenhouse, where the temperature must not be lower than 5°C. The placement area for Murraya paniculata bonsai should be sprayed with water frequently to maintain air humidity.

Murraya paniculata likes a humid environment, but because the potting soil of Murraya paniculata bonsai is limited, it dries out easily. If water is not supplied in time, it will die from lack of water. Although Murraya paniculata bonsai needs constant watering, it should not be watered too much. Excessive moisture will cause leggy growth of Murraya paniculata. Long-term overly wet potting soil causes poor root respiration and can easily lead to root rot and death. Therefore, watering Murraya paniculata bonsai should follow the principle of “do not water until dry, and water thoroughly when watering.”

The nutrients in the potting soil are limited. In order to supply the nutrients needed for the growth of Murraya paniculata, appropriate fertilizer should be supplemented. However, Murraya paniculata bonsai grows slowly, so too much fertilizer should not be applied, as this would cause leggy growth and affect its appearance. Fertilization should be moderate, and the type of fertilizer and nutrient content should be controlled.

Murraya paniculata likes a warm and humid environment, so it should be placed in a humid environment. In summer, attention should be paid to shading, and in winter, cold protection is needed.

Murraya paniculata has strong sprouting ability, so crossing branches, overlapping branches, dead branches, and diseased or pest-infested branches need to be pruned continuously and frequently. A major thinning prune in August is best.

Generally, it should be carried out in April——May. Repot once every 2——3 years.

Murraya paniculata has relatively few pests and diseases. Longhorn beetles, aphids and scale insects occur in small numbers. For control, manual catching can be done, or lime sulfur mixture can be used for prevention and spraying. It is best to spray lime sulfur mixture once each before winter and when spring turns warm.

After transplanting, the plant begins to produce flower spikes and bloom and bear fruit after a period of growth. In order to reduce nutrient consumption, ensure sufficient nutrient supply to the main branches, and promote growth, corresponding measures for removing flowers and fruits must be taken. Murraya paniculata can bloom all year round. Flowers that bloom from spring to early summer generally do not bear fruit, while flowers that bloom from late summer to early autumn will bear fruit in September to October. According to this characteristic, for the flower spikes produced by smaller plants, because the number of flowers is small but the impact on the plant is great, they can be removed manually in time; however, for plants that have grown for many years, because the plant shape is too large, timely flower removal is relatively difficult, and the impact of flowering on the plant is not as great as on small plants. Therefore, a one-time fruit removal can be organized in September to October when fruit is set, reducing nutrient absorption by the retained fruit.

It likes warmth. The most suitable growth temperature is 20°C to 32°C. It is not cold-tolerant. In winter, when the minimum temperature drops to about 5°C, move it indoors at low temperature (5°C to 10°C) for overwintering. Moving it in too early is not conducive to hardening its cold tolerance. If the room temperature is too low, it easily loses leaves, affecting growth the following year. Below 0°C, it may freeze to death. If the room temperature is too high, the plant cannot enter dormancy well, and may even sprout indoors. When moved outdoors, a cold wind may cause the buds to retract. When new buds emerge again, it affects the growth of that year.

Murraya paniculata is a sun-loving tree species. It should be placed in a place with sufficient sunlight and air circulation (at least five or six hours of direct light per day) to have lush leaves, abundant flowers and fragrance. When flowering, it can be moved to a windowsill, filling the room with fragrance. After the flowers fade, it still needs to be placed in a sunny place. Growth in partial shade is not as robust as in a sunny place, and the fragrance of the flowers is also weaker. If too shady, the branches become thin and soft, the leaf color becomes light, and there are few or no flowers. In winter, when brought indoors, it should also be placed in a sunny place.

Household potted Murraya paniculata rarely produces seeds, so propagation generally uses the air layering method. In May and June, select robust growing branches, and at an appropriate position use a sharp knife to score the bark. Use a mixture of moss and leaf mold as moisture-retaining soil, wrap it well with plastic film, and spray water frequently to keep it moist. After about 2 months, the wound heals and new roots grow. In September and October, cut it off and unwrap the film. Do not scatter the wrapped moss and leaf mold. Plant it in a pot. In late October, move it indoors for care, and in early spring at Qingming move it outdoors. With routine care, it can bloom in 2 to 3 years. In addition, the division method can also be used. In spring, use a sharp knife to cut off rooted suckers growing from the base of the old plant, plant them separately in pots, first place them in a shaded place for 10 to 15 days, and then move them to a sunny place for care.

1. Organic fertilizer and cake fertilizer must be fully decomposed before use; otherwise, fermentation in the potting soil can easily burn the roots.

2. Liquid fertilizer should not be too concentrated and must be diluted before use; otherwise, fertilizer damage can easily occur.
