What to Do When an Orange Jessamine's Leaves Turn Yellow? Causes and Solutions

The orange jessamine (Aglaia odorata) is a flowering plant native to southern Asia, and it is now distributed throughout the tropical regions of the world. In our country, it is mainly found in subtropical regions such as Yunnan, Guangdong, Guangxi and Fujian, and for home cultivation it is usually grown in pots. Many people run into the problem of yellowing leaves when growing orange jessamine, so below Qinnong Net will explain what to do when an orange jessamine's leaves turn yellow.

To understand how to deal with yellowing orange jessamine leaves, we first need to understand the causes of the yellowing. Qinnong Net introduces five points here, covering temperature, ventilation, soil, light and watering, all of which relate to routine care. Let's take a closer look below.

1. Low temperature

If the orange jessamine's leaves turn yellow in winter, the first thing to consider is whether low temperature is the cause, as low temperature is the most common reason for yellowing in orange jessamine. Orange jessamine likes a warm environment, and when the overwintering temperature drops below 5°C it will suffer cold damage. In the early stages of cold damage, the leaves gradually turn yellow and then fall off. Another point is that exposure to cold wind can make the orange jessamine's leaves turn yellow overnight.

If the orange jessamine suffers cold damage or is exposed to cold wind, it is very difficult to save; in mild cases it affects the flowering the following year, and in severe cases it can even cause the plant to die. Therefore, attention must be paid to keeping it warm in winter.

2. Improper watering

Orange jessamine is a moisture-loving plant, but if it is not repotted for a long time, the nutrients in the soil will decrease and its air permeability will weaken. After watering, the root system will remain wet for a long time, its respiration will be inhibited, and root rot will occur, which leads to yellowing and dropping of the leaves. If you find that the roots have necrotic areas, you must stop watering immediately; if the potting soil is already very wet, you can take the orange jessamine out of the pot and replant it.

In addition, in the high-temperature season, if watering is not done in time and the potting soil stays too dry for a long time, the leaves will also turn yellow within a short period. At this time, do not water it all at once; proceed gradually so the plant can slowly recover.

3. Insufficient light

Orange jessamine needs plenty of light to grow. If the light is insufficient, the nutrients produced by photosynthesis will be reduced, and the leaves will also turn yellow and drop. If the orange jessamine develops yellowing and leaf drop due to insufficient light, we should immediately move it into the sunlight and rotate its direction every month so that it receives light evenly; in this way the yellow leaves will gradually recover.

4. Alkaline soil

Orange jessamine needs slightly acidic soil to grow. The soil in southern parts of our country is quite suitable for orange jessamine's growth, but in the north the soil is alkaline, and growing orange jessamine in such soil will cause the leaves to turn yellow. The simplest solution is to change the soil's pH; you can apply alum fertilizer water 3 to 5 times a year. Alum fertilizer water contains substances such as ferrous sulfate, which can both increase soil acidity and improve soil fertility, so it can be said to serve two purposes at once.

5. Poor ventilation

Most plants need to grow in an environment with good air quality and good ventilation. If the orange jessamine grows for a long time in a place without air circulation, it is also prone to yellowing leaves. For home cultivation, pay attention to opening windows for ventilation more often in daily life, and promptly prune away excessively dense inner branches and leggy branches to ensure good light and ventilation.

The above is Qinnong Net's explanation of the causes of and solutions for yellowing leaves in orange jessamine, and we hope it can be of some help to everyone. When the orange jessamine blooms, its fragrance is delightful, and it can be placed in the living room or study at home, pleasing to the eye and refreshing to the heart.
