Orange jessamine (scientific name: Murraya exotica), 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, moon orange. Latin name: Murraya exotica L. An evergreen shrub of the Rutaceae family and the genus Murraya, sometimes able to grow into a small tree form, with graceful plant posture, elegant branches and leaves, and a rich floral fragrance. The chemical components contained in the roots, stems and leaves are similar to those of Murraya paniculata. It is produced in the southern parts of five provinces and regions: Taiwan, China, Fujian, Guangdong, Hainan and Guangxi. It is commonly found in shrub thickets on flat land, gentle slopes and small hills not far from the coast. It likes to grow in sandy soil and sunny places. In the southern regions it is mostly used as hedging material, or as an ornamental accent for flower gardens and hotels, and also as bonsai material.


Cultivation Methods for Orange Jessamine

1. Propagation. Orange jessamine is mostly propagated by seeds, cuttings and layering.

Seed propagation: first pick ripe fresh fruits of orange jessamine, remove the skin and flesh in clean water, dry the inner kernels, and sow in either spring or autumn. Before sowing, the nursery bed should be prepared by deep digging and breaking up the soil. Sprouting occurs in about one month.

Cutting propagation is best carried out in spring or during the rainy season in July and August. Select mature branches of orange jessamine that are more than one year old, make the cut smooth, insert them into the seedbed, and water thoroughly. With proper management, spring cuttings can be planted out in the same year, while autumn cuttings need to be planted out the following year.

Layering propagation: layering during the rainy season gives the *** highest survival rate. Select semi-mature branches, cut and wound the outer part that is pressed into the soil so that it roots and sprouts better, and it can be separated and planted out the following year.

2. Care. Orange jessamine likes a growing environment with good light and suitable warmth, and can tolerate partial shade. Because it is not cold-tolerant, it needs to be moved indoors for care in winter. The indoor temperature in winter should not be too high, otherwise it will force buds, and when cold air arrives the buds will shrink back again, affecting the growth of the following year.

When transplanting orange jessamine or changing its soil, mix some nitrogen-phosphorus-potassium compound fertilizer into the new soil, which can give the plant ample nutrition and more flower buds. Do not use too much nitrogen fertilizer, to avoid excessive vegetative growth. Orange jessamine originated in the southern regions and likes slightly acidic soil, so once or twice a year apply alum fertilizer water at intervals. Orange jessamine is drought-tolerant, so it should be watered less; in the rainy season, it should be placed in a sheltered place away from rain.


Care and Management


When planting, place a few pieces of animal hoof and horn slices at the bottom of the pot as base fertilizer. In addition to applying base fertilizer at planting, when potting up or repotting and changing soil, it is advisable to mix some bone meal or nitrogen-phosphorus-potassium compound fertilizer into the growing medium. During the growing period, apply a decomposed organic liquid fertilizer once a month. Do not apply nitrogen fertilizer alone, otherwise the branches and leaves will grow excessively without forming flower buds. From April to June, to promote flower bud differentiation, spray a 0.2% potassium dihydrogen phosphate solution on the leaves once a month, and pour the leftover solution at the roots. Because orange jessamine is native to the south and likes slightly acidic soil, it is best to apply "alum fertilizer water" twice a year at intervals. However, do not fertilize during the winter dormancy period. If cultivating young trees, fertilizer and water can be appropriately increased to promote faster growth and development, so as to reach the height and thickness required for shaping as early as possible.
Orange jessamine is drought-tolerant, so watering should follow the principle of watering when dry and stopping when wet, and there should be no water accumulation in the pot. During continuous rainy weather, the pot should be laid on its side or placed in a rain-sheltered place. If watered too much, it often causes root rot. If the leaves curl and lose their luster, this is a signal of root rot, and attention should be paid to taking remedial measures as early as possible. First, control watering and observe the changes. If after 2 to 3 days there is not only no improvement but it becomes even more serious, then the plant should be taken out of the pot, the soil around the roots washed off with water, the plant dried, then soaked in a 1:5000 potassium permanganate solution for disinfection, and then placed in a 1:2000 naphthalene acetic acid rooting solution and soaked for 8 hours before being repotted. During the growing period, watering should not be too much; it is enough to keep the soil slightly moist at all times. In the hot summer season, watering should not be too much, but there must be no water accumulation in the pot (bucket). At this time, it is also necessary to frequently spray water on the branches and leaves, which can both cool and humidify, and help make the branches and leaves glossy green. After being moved indoors in winter, water less, as long as the potting soil is kept moist.

In spring, a pruning should be carried out together with planting or repotting. Over-dense branches and leggy branches should be shortened or thinned at any time. Major pruning should be carried out in late October or November. Do not prune heavily during the flowering period, so as not to affect the ornamental effect.


Precautions for Orange Jessamine

Orange jessamine should not be placed in a place with direct sunlight. Placing it in a place with sparse light can make the flowers and leaves luxuriant and the floral fragrance rich. Courtyard cultivation is a relatively ideal choice.

Orange jessamine likes fertile, loose soil. Newly transplanted orange jessamine should first be placed in a shady place for a few days, and after growth is stable, moved to a place with good light conditions. Orange jessamine is in its dormancy period in winter, so do not fertilize. If the leaves are found to be curled and lusterless, root rot may have occurred, and attention should be paid to early prevention and control. First, water less. If there is still no improvement, it should be pulled out with the roots, dried, disinfected in diluted potassium permanganate solution, and then repotted.
