What to Do When Night-Blooming Jasmine Leaves Turn Yellow? Causes and Solutions

Night-blooming jasmine, also known as night fragrant flower, night orchid fragrance, night clove, and thousand-mile fragrance, is a weak vine-like shrub of the genus Cestrum in the Solanaceae family. Its flowers are fragrant, especially stronger at night, and it is often cultivated for ornamental purposes. However, during cultivation, the leaves of night-blooming jasmine often turn yellow, and people do not know what to do. Below, let us take a look at what to do when night-blooming jasmine leaves turn yellow!

Yellowing Caused by Overwatering

The tender leaves at the top of night-blooming jasmine turn pale yellow, the old leaves gradually turn yellow as well, and the new shoots wither. This is because overwatering, rain, or excessive watering causes the pot soil to become too wet, the soil lacks oxygen, and the fibrous roots rot. The correct approach is to loosen the soil regularly and control watering.

Yellowing of Leaves Caused by Lack of Water

The color of the leaves at the top of night-blooming jasmine is normal, but the lower leaves gradually dry, turn yellow, and fall off from the bottom upward. This is generally caused by the pot soil being too full, so water cannot penetrate thoroughly for a long time, causing the lower leaves and branches to age. The excess pot soil should be properly removed, and watering should be done in appropriate amounts to keep the soil moist.

Yellowing of Leaves Caused by Lack of Fertilizer

The leaves of night-blooming jasmine are thin, tender, and yellow, generally caused by the plant being large while the pot is small, or by not repotting or changing the soil for a long time, resulting in insufficient fertilizer. Fertilizer and water should be gradually increased, but care should be taken not to make them too concentrated. Potted flowers should be repotted once every one to two years, and tree bonsai once every 2 to 4 years. When repotting, add a small amount of base fertilizer at the bottom of the pot and replace part of the soil with new soil.

Yellowing of Leaves Caused by Fertilizer Damage

When night-blooming jasmine shows uneven and unspread leaves, thick new leaves, and yellowing old leaves, it is mostly caused by excessive fertilizer. Water more frequently, pause fertilization, and sow some vegetable seeds or other seeds in the pot. After the seedlings emerge, pull them out to consume the excess fertility in the pot.

Yellowing of Leaves Caused by Pests and Diseases

Yellow spots appear on night-blooming jasmine due to scale insect damage. Rough, dry, and yellow leaves are caused by red spider mite damage. You can spray with 70% trichlorfon at a dilution of 1:1000 or 40% dimethoate diluted 2000 times with water. Leaf yellowing caused by viruses will spread rapidly into patches. The affected leaves should be promptly removed and burned, then carbendazim or Bordeaux mixture should be sprayed for control. Do not spray excessive pesticide, otherwise pesticide damage may also occur.

Yellowing Caused by Insufficient Light

If night-blooming jasmine is placed indoors in a place without sunlight for a long time, its leaves are prone to turning yellow. Some other sun-loving plants such as jasmine and white orchid will also develop yellow leaves if they do not receive enough light. Conversely, some plants that prefer cool environments, such as lucky bamboo, fuchsia, and Chloranthus, will also develop yellow leaves and drop them if exposed to high temperatures and strong sunlight with improper shading.

Summary: That is all for what to do when night-blooming jasmine leaves turn yellow. We should know that there are many reasons for the leaves of night-blooming jasmine to wither and turn yellow, and the characteristics of yellowing also differ. Therefore, analysis should be made according to the specific situation, and judgment and treatment should be made after comparison.
