What to Do When Aglaia duperreana (Mock Lime) Drops Its Leaves? The Latest Solutions
Aglaia duperreana likes a ventilated, airy, humid, warm and sunny environment. The Aglaia duperreana plants that hit the market in spring are mostly shipped from the south to the north, and the climate difference between the two regions is enormous, posing a huge threat to their survival. Especially in early spring, even for varieties cultivated locally, if they are not managed properly and are moved outdoors too early, they can still drop a large number of leaves or even die, let alone varieties from elsewhere.
Why does Aglaia duperreana keep dropping its leaves?
1. Aglaia duperreana fears wind and cold. Once exposed to wind and cold, its leaves will suddenly drop in large numbers within a short period. During indoor care, leaf drop often occurs if the plant is exposed to wind and cold. Therefore, in spring it is essential to protect it from wind and cold.
2. When Aglaia duperreana is kept at low room temperature with insufficient light for a long time, excessive watering damages the roots and leaves, causing the green leaves to drop. For a plant that has dropped its leaves, immediately stop watering, misting and fertilizing, and use the methods of “loosening the soil to dissipate moisture” and “changing the soil to absorb moisture”. Place it in warm sunlight, and wait until the potting soil is dry and loose before watering again, moistening it gradually until it slowly recovers.
3. Aglaia duperreana tends to drop a large number of leaves over winter. Judging from the signs, blackish-brown wilted leaves are a sign of freezing, and the temperature should be raised promptly or the plant moved to a warmer place so it can gradually revive. Yellow, withered and fallen leaves are caused by poor ventilation or soil that is too dry. Green fallen leaves are caused by soil that is too wet. In winter, the physiological activity of Aglaia duperreana is weak, so low temperature with high humidity, or dry air, must be avoided. Persistent low temperatures below 5°C, draughts and long-term insufficient light can all also cause leaf drop.
4. Cold spring winds blowing directly on the plant also easily cause leaf drop. Move it outdoors only after Qingming when the temperature is stable; this all helps protect the leaves.
5. Fertilizer damage: improper fertilization can cause fertilizer damage and leaf drop. Fertilizer must be fully fermented and decomposed. If raw fertilizer is applied, not only will it fail to make Aglaia duperreana grow strong, but the heat generated during the fermentation of the raw fertilizer will burn the root system; if you apply inorganic fertilizer, applying too much at one time or direct contact with the chemical fertilizer will also damage the roots and cause leaf drop.
How can you keep Aglaia duperreana from dropping its leaves?
1. Fertilizing: generally apply fertilizer once a month, mainly organic fertilizer and high-efficiency phosphorus-potassium fertilizer, and never apply too much nitrogen fertilizer. Each time, apply 25 to 30 grams per pot of composted, decomposed and deodorized peanut cake fertilizer, rapeseed cake fertilizer or tea seed cake fertilizer, plus 15 to 20 grams of potassium dihydrogen phosphate or high-efficiency biological phosphorus-potassium fertilizer, mixed with 2 to 3 kg of clear water or composted, decomposed and deodorized human and livestock manure water, and pour it on
2. Watering: keep the potting soil moist all year round, never let it become so dry that it cracks, but do not let it stay too wet for long either, otherwise the roots will be suffocated, rot, and the leaves turn yellow. Generally, water once a day with clear water in summer and autumn, and once every 2 to 3 days in winter and spring, so that the water can quickly penetrate into the potting soil rather than pooling on top. At the same time, frequently spray clear water on the branches and leaves, especially during high summer temperatures and dry winter periods, spraying all the branches and leaves evenly until water droplets begin to drip down, so as to keep the branches and leaves moist
3. Spraying: potted Aglaia duperreana is quite seriously harmed by pests and diseases such as powdery mildew, leaf spot, anthracnose, red spider mite, scale insects, aphids and rust mites, which make the branches and leaves turn yellow and die. Every 15 to 20 days, spray the leaves once with a clarified liquid leached from a mixture of 25 to 30 times dry, clean plant ash and superphosphate, or a 0.1% clarified limewater solution, for pollution-free control, so as to protect the branches and leaves and prevent damage from various pests and diseases.
