What to Do When Aglaia Leaves Turn Black? Cause Analysis and Solutions
Aglaia, also known as four-season Aglaia or small-flowered Aglaia (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 rich fragrance when in bloom, it is deeply loved by people. But I wonder if you have ever come across Aglaia leaves turning black. After some Aglaia plants are bought from the market and grown at home for a period of time, their leaves turn black. What is going on? Today Qinnongwang will share with you the reasons why Aglaia leaves turn black and the corresponding solutions.
1. Reasons for Aglaia Leaves Turning Black
There are many reasons why Aglaia leaves turn black. Qinnongwang has summarized here that they are mainly related to three aspects: environment, temperature and fertilizer. Aglaia likes warmth and prefers sufficient light and fertilizer. Its most suitable growing temperature is 20°C-25°C. If the temperature is high and there is sufficient light, the flowers produced by Aglaia will have a rich fragrance. If the growing environment is unsuitable, then Aglaia may bloom little or not at all, and the leaves will also be affected to some extent.
2. Solutions for Aglaia Leaves Turning Black
1. Cultivation environment
Growers who have newly bought flowers from the market should not change the soil first, and especially should not fertilize the Aglaia. You should know that plants all have their own adaptation process. It is recommended that you first let the Aglaia 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 sunlight. 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 must not be overwatered. When watering, water thoroughly through the original root ball. If the flower came from a greenhouse, you can spray water in the early stage to maintain moisture. If the potting soil is too wet, you can take the potting soil together with the Aglaia out of the pot. It is recommended that you do not water too frequently. If the Aglaia is not dry, there is no need to water it; if you do water, be sure to water thoroughly.
4. Light
In winter, the plant can be moved indoors to a balcony, windowsill and other places. Apart from shading during strong midday sun, you can provide the plant with plenty of sunlight. For newly sprouted Aglaia, however, we must not expose it to excessive sun.
5. Fertilizing
When Aglaia does not have enough nutrients, its leaves will turn black. When Aglaia blooms many times and its flowers are extremely abundant, each blooming consumes a relatively large amount of nutrients, so growers should replenish nutrients in time after the flowers fade, and can use acidic flower soil rich in leaf mold. Only in this way can it keep blooming and have luxuriant branches and leaves. In summer and autumn, a nutrient solution can be sprayed every week to ensure that the plant has luxuriant branches and leaves.
The above is Qinnongwang's introduction to the solutions for Aglaia leaves turning black. Aglaia is a plant very suitable for indoor potting, and it also has a very long lifespan. Placing such a potted flower in the living room or study at home can decorate the environment and purify the air.
