What to Do When Aglaia odorata Leaves Turn Black? Find the Cause and Treat It Accordingly
Aglaia odorata, also known as four-season Aglaia odorata or small-flowered Aglaia odorata, is an evergreen shrub or small tree mainly distributed in the subtropical regions of southern China. This plant prefers a warm and humid growing environment and is not cold-tolerant. Because of its strong fragrance when in bloom, it is deeply loved by people. But I wonder if you have ever encountered blackened leaves on Aglaia odorata. Some plants bought from the market and grown at home for a period of time will develop blackened leaves. What is going on? Today Qinnongwang will share with you the causes of blackened Aglaia odorata leaves and the corresponding solutions.
I. Causes of Blackened Aglaia odorata Leaves
There are many causes of blackened Aglaia odorata leaves. Qinnongwang has summarized here that they are mainly related to three aspects: environment, temperature, and fertilizer. Aglaia odorata likes warmth and prefers sufficient 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 Aglaia odorata will have a strong fragrance. If the growing environment is unsuitable, then Aglaia odorata may bloom less or not bloom at all, and the leaves will also be affected to some extent.
II. Solutions for Blackened Aglaia odorata Leaves
1. Cultivation Environment
Growers should not repot newly purchased flowers from the market at first, and especially should not fertilize Aglaia odorata. You should know that plants all have their own adaptation process. It is recommended that you first let the Aglaia odorata 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 that you place the plant in a warm, dry place without direct light. A temperature between 20 and 35 degrees is best, and it can bloom 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
Aglaia odorata must not be overwatered. When watering, soak the original soil ball thoroughly. 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 Aglaia odorata out of the pot. It is recommended that you do not water too frequently. If the Aglaia odorata 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, and similar places. In addition to shading during strong midday sun, you can provide the plant with plenty of sunlight. For newly sprouted Aglaia odorata, we should not expose it to excessive sun.
5. Fertilizing
When Aglaia odorata does not have enough nutrients, its leaves will turn black. When Aglaia odorata blooms many times and the flowers are extremely lush, each blooming consumes a lot of nutrients, so growers should replenish nutrients promptly after the flowers fall. An acidic flower soil rich in leaf mold can be used. Only in this way can it bloom continuously and have luxuriant branches and leaves. In summer and autumn, a nutrient solution can be sprayed weekly to ensure luxuriant branches and leaves.
The above is what Qinnongwang has introduced regarding the solutions for blackened Aglaia odorata leaves. Aglaia odorata is a plant very suitable for indoor potting, and its lifespan is also very long. Placing such a potted flower in the living room or study at home can play a role in decorating the environment and purifying the air.
