What to Do When a Newly Bought Azalea Drops Its Leaves? Causes and Solutions
For those of you who want to grow azaleas, the azaleas you buy from the flower market are generally grown in greenhouses, and when you bring them home from the flower market, they no longer have the greenhouse environment, which easily leads to yellowing leaves and wilting in azaleas. At this point, you need to take some measures! The specific steps are as follows.

1. First, you should figure out the condition of the azalea's root system
Azaleas grown in greenhouses have a very good growing environment and proper care, so once these conditions are lacking, leaf drop occurs. In fact, comparatively speaking, it is like a pampered child suddenly sent to live in a poor area, which makes it hard for them to adapt.
2. Measures
(1) For a newly bought azalea, you should give it as much air humidity as possible and keep its potting soil moist. Do not place it directly outdoors in cold wind. Those caring for it at home can place it on a sunny south-facing balcony.
(2) In winter and early spring, it should be given sufficient light, and the temperature should not be lower than 12°C, preferably between 18 and 22°C.
(3) Once you place the azalea in one spot to grow, do not casually move it to another location, to avoid the azalea failing to adapt due to drastic temperature changes. If the azalea's tender leaves wilt, this indicates a lack of water. If the potting soil is not dry, you should spray water on the pot and the surrounding environment to increase the ambient humidity.
(4) If you find that the azalea you bought home already shows signs of root damage, at this point you should first nurse its roots. If it still cannot recover, you should remove the azalea's flower buds and keep only a few buds, which can reduce the azalea's nutrient consumption. After it recovers, resume normal care operations.
(5) In autumn, we should focus on spraying water and use watering as a supplement. At this time, the climate has gradually begun to cool and the temperature has dropped, so the azalea's potting soil no longer dries out so easily. Once you water it too much, root rot can easily occur.
(6) Prune it. If the azalea has yellow leaves or diseased branches, these can also easily cause leaf drop. At this point, you should promptly cut off these branches and leaves, so as to prevent them from consuming too many nutrients.
The editor reminds everyone that if the azalea you bought home shows leaf drop, you should pay attention at this point. When you see this phenomenon, you can first refer to the several situations introduced above by the editor, then find the corresponding method, so as to solve this problem in time.
Why Do Azaleas Drop Leaves, and How to Solve Azalea Leaf Drop
The main causes of azalea leaf drop are improper watering and fertilizing, alkaline soil and water, nutrient deficiency yellowing, and poor root absorption. Azaleas have fibrous roots and are not drought-tolerant. During cultivation, you must water them in time, but also be careful not to water too much; an appropriate amount is enough. Normally, you should appropriately give azaleas some alum fertilizer water, and give azaleas reasonable light.
Cause of azalea leaf drop 1: Improper watering and fertilizingThis is mainly caused by poor management. The azalea's root system is delicate and weak; it fears drought, waterlogging, and heavy fertilizer. If watering is insufficient or missed, it will cause leaves to wilt and droop, and in severe cases the leaf tips will scorch, with leaves and flower buds falling off in large numbers. If watered too much and the soil stays wet for a long time, it will suffocate and rot the roots, easily causing the lower old leaves to turn yellow and fall off, and in severe cases the leaves are almost completely shed. Fertilizing too heavily or applying unrotted raw manure will cause fertilizer damage to the plant; in mild cases the leaves turn yellow, the leaf tips scorch, the branch tips shrivel, and a large number of leaves fall, while in severe cases the whole plant dies. Once fertilizer damage occurs, increase watering so the fertilizer flows out through the drainage holes, and if necessary, repot and change the soil.
2. Alkaline soil and waterAzaleas like slightly acidic, loose soil. If the potting soil is alkaline or you water with alkaline water for a long time, it will inevitably affect the roots' absorption of elements such as nitrogen and iron, causing iron deficiency and other issues that lead to leaf yellowing. To prevent yellowing disease caused by iron deficiency, you can buy a small packet of ferrous sulfate (commonly known as black alum) at a chemical store. Soak it in a water vat until it turns reddish-brown, then water with 0.2% black alum water every day, and the leaves will not turn yellow or even dry up and fall off. In addition, you can also add a few drops of edible rice vinegar to the water used for watering flowers, which can also increase the soil's acidity.
3. Nutrient deficiency yellowingWhen the plant lacks iron or magnesium, it will cause the areas between the azalea's leaf veins to lose their green color, but the leaf veins remain green; when it lacks sulfur, it will also cause young leaves to turn yellow, and in severe cases turn white and spread to old leaves. You can determine which element is lacking through leaf analysis and soil analysis, then supplement the corresponding element. Usually, iron deficiency is the most common, and whenever the leaves turn yellow it is assumed to be caused by iron deficiency, but sometimes this is not the case.
4. Poor root absorptionWhen various azaleas are kept under the same environmental conditions and cared for by the same person, some varieties yellow easily, such as “Xintiandi” and “Dahong Shuangtao”, which is related to the plant's own absorption function and environmental adaptability. This is especially obvious when summer temperatures are high, and after the autumn cool most improve somewhat or return to green. Although the symptoms resemble iron deficiency, supplementing iron has no effect on them. For this type of yellowing phenomenon, measures to protect and care for the roots should be taken. In winter, keep a relatively high temperature; in summer when it is hot, provide shade and spray water around the environment to cool it down, maintain good ventilation, and promote healthy growth and development of the plant's root system.
5. Temperature/sunlightTemperature and humidity are unsuitable: the temperature is either too high or too low, and the humidity is either dry or damp. None of these environments suit azalea growth, so leaf drop often occurs. Long-term lack of light: if the azalea is placed in a dark corner for a long time, then leaf drop and withering are inevitable. As the saying goes, everything that grows needs the nourishment of sunlight; without light, it naturally cannot survive.
Solutions for azalea leaf drop1. Water an appropriate amount: Azaleas have fibrous roots and are not drought-tolerant. During cultivation, you must water them in time, but also be careful not to water too much; an appropriate amount is enough. Be sure to remember "water thoroughly when you water", and normally spray water on the leaves and around them to increase ambient humidity.
2. Keep the soil acidic: Normally, you should appropriately give azaleas some alum fertilizer water, or add a little ferrous sulfate to the water when applying it, to maintain the acidity value of the soil in which the azaleas are grown.
3. Fertilize an appropriate amount: Add an appropriate amount of slow-release fertilizer to the azalea's potting soil (the fertilizer is coated with an organic film, and the fertilizer is slowly released through the film's permeation to supply plant nutrients), which is safe, clean, long-lasting, and produces bright flowers and lush leaves. This fertilizer is often used in horticultural production; it is both labor-saving and clean, and the azaleas grown have lush leaves and bright flowers.
4. Reasonable sunlight: Give the azalea reasonable light. You can place the azalea in a place with sufficient light, and after the weather warms up in spring, move it to a semi-shady place. It is best to grow the azalea in a place with morning and evening sunlight and shelter from the wind.
