How to Grow Fagraea ceilanica? A Detailed Guide to Light, Water, Fertilizer, Propagation, and Pest and Disease Control

Fagraea ceilanica is an evergreen tree or shrub, sometimes climbing, fond of sunlight but also tolerant of shade, with fairly strong cold resistance; in the southern subtropical regions it stays green and lush all year round and grows well. It is not demanding about soil and is highly adaptable, easy to grow and cultivate, with dense branches and leaves and a graceful tree shape; its leaves are nearly succulent, dark green and glossy, making it an excellent indoor foliage plant. To grow Fagraea ceilanica well, just pay attention to the following points.

Get light adjustment and humidity boosting right, and the leaves will stay glossy green

Fagraea ceilanica likes a sunny, warm environment, but in summer and autumn avoid direct midday sunlight, so the leaves do not get scorched. It has fairly strong phototropism, so when grown indoors the pot should be rotated once every 10 to 15 days to prevent lopsided growth and an uneven crown; in places with insufficient light, do not keep it there for more than two months, otherwise insufficient light will cause the leaves to turn yellow and drop.

Fagraea ceilanica also likes high air humidity and a well-ventilated environment. In summer, water more generously, place the pot in a shady spot, and frequently spray water on the leaves to raise local humidity, so the leaves can stay dark green.

Keep up with water, fertilizer and pruning, and the plant shape will look good

During the growing season, apply a thin, well-rotted soybean cake fertilizer with a moderate ratio of nitrogen, phosphorus and potassium once every 15 to 20 days. Be careful not to apply too much nitrogen fertilizer, otherwise the plant will grow leggy, which both affects flowering and ruins the tree shape. After early autumn, appropriately spray 0.2% to 0.3% monopotassium phosphate; in late autumn gradually reduce watering and stop fertilizing. For potted Fagraea ceilanica in the north, keeping it indoors at above 5°C in winter is enough for it to overwinter safely.

Fagraea ceilanica has fairly strong sprouting and tillering ability and is extremely tolerant of pruning, so it can be shaped freely during the growing season, usually pruned into a spherical, platform or fan shape. To maintain a graceful tree shape, the tiller buds at the base of the plant should be cut off in time so they do not waste nutrients.

For cultivation, choose loose, fertile sandy loam with good drainage. For potted plants in the north, you can use a mix of 7 parts leaf mold, 1 part river sand, 1 part composted organic fertilizer, and 1 part fermented sawdust; loosen the soil once a month during the growing season so the roots always stay well aerated.

Cuttings root easily; prevent and treat pests and diseases early

Fagraea ceilanica can be propagated by cuttings, sowing, layering or division, with cuttings being the main method in the north: in July and August, cut current-year branches into 8 to 10 cm sections as cuttings, keep 3 to 4 top leaves, insert them into clean river sand, and keep them in a greenhouse; they will root in 40 to 60 days, with a survival rate of over 85%.

As for diseases, anthracnose mostly occurs on young branches and leaves. The lesions are nearly round to irregular and sunken, with brown edges and grayish-white to grayish-brown centers, bearing sparse small black dots (the acervuli). At the early stage of the disease, spray 50% carbendazim wettable powder at 800 times dilution plus 25% chlorothalonil wettable powder at 800 times dilution, or 25% tanteling wettable powder at 500 times dilution, spraying alternately once every 10 days for 3 to 4 times in a row. In the intense heat of midsummer, if shading is inadequate, the young shoots and leaves of potted Fagraea ceilanica are also prone to sunscald, developing grayish-white or pale white scorched spots. In this case, use a shade net for shading, adjust the position appropriately, increase the frequency and amount of watering during hot, dry seasons, and sprinkle water on the leaves if necessary; move already scorched plants into a shade shed in time, cut off the damaged leaves, and strengthen water and fertilizer management to help them recover.

As for insect pests, the main one is the Chinese gall thrips; both adults and nymphs damage young leaves and buds and generally do not harm old leaves. They rasp and suck sap along both sides of the main vein of young leaves, forming galls on the leaf surface; in severe cases the leaves become distorted or curl along the main vein, and adults and nymphs are often seen gathered and damaging a single leaf. Control can be done in three ways at once: when only a few occur, cut off the damaged branches and leaves and burn them in a centralized manner; use natural enemies such as the seven-spot ladybird and the tortoise-shell ladybird, whose adults and larvae can both prey on thrips; for unaffected plants, spray Tianwang at 2500 times dilution or Jinzun at 1000 times dilution preventively when new leaves emerge, and for affected plants spray once every 6 to 7 days, for 3 to 4 consecutive sprays depending on the situation.

Overall, Fagraea ceilanica is easy to grow and cultivate; get light, humidity, water, fertilizer and pruning right, and also prevent anthracnose, sunscald and thrips well, and you can grow it with dense branches and lush, glossy green leaves.
