Blackening Leaves on Orange Jasmine (Aglaia odorata): Causes and Solutions

Orange jasmine, also known as four-season orange jasmine or broken orange jasmine, is an evergreen shrub or small tree that is deeply loved for its rich fragrance when in bloom. Some orange jasmine plants bought from the market and grown at home for a period of time will develop blackening leaves, so what should be done when orange jasmine leaves turn black? What causes it?

1. Causes of Blackening Orange Jasmine Leaves

There are many causes of blackening orange jasmine leaves, mainly related to three aspects: environment, temperature and fertilizer. Orange jasmine likes warmth and prefers light and fertilizer. Its most suitable growing temperature is 20°C-25°C. If the temperature is high and light is sufficient, the flowers produced by orange jasmine will have a strong fragrance. If the growing environment is unsuitable, orange jasmine may bloom little or not at all, and the leaves will also be affected to some extent.

2. How to Handle Blackening Orange Jasmine Leaves

1. Growing Environment

Growers who have just bought a new plant from the market should not change the soil first, and especially should not fertilize the orange jasmine. You should know that plants all have their own adaptation process. It is recommended to first let the orange jasmine adapt to the growing environment, such as humidity, temperature and light, otherwise it is easy to weaken the plant and harm its later growth.

2. Humidity

It is recommended to place the plant in a warm, dry place without direct light. A temperature between 20-35 degrees is best. It can open as many as five times in summer and autumn. Generally speaking, when the temperature is above 30 degrees, the floral fragrance is the strongest; conversely, if the temperature and light do not meet the requirements, the floral fragrance will be very faint.

3. Watering

Orange jasmine must not be overwatered. When watering, soak the original root ball through. If the flower came from a greenhouse, you can spray water in the early stage to maintain humidity. If the potting soil is too wet, you can take the potting soil together with the orange jasmine out of the pot. It is recommended not to water too frequently. If the orange jasmine soil is not dry, there is no need to water; if you do water, be sure to water thoroughly.

4. Light

In winter, the plant can be moved indoors to a balcony, windowsill or similar place. Apart from needing shade during strong midday sun, you can provide the plant with plenty of sunlight. For newly sprouted orange jasmine, however, we must not expose it to excessive sun.

5. Fertilizing

When orange jasmine does not have enough nutrients, its leaves will turn black. When orange jasmine blooms many times and the flowers are extremely abundant, each flowering consumes a relatively large amount of nutrients, so growers should replenish nutrients promptly after the flowers fade. An acidic flower soil rich in leaf mold can be used, so that it can keep blooming and have luxuriant branches and leaves. In summer and autumn, a nutrient solution can be sprayed weekly to ensure luxuriant branches and leaves.
