How to Fix Yellowing and Dropping Leaves on Azaleas
Azaleas are neutral flowers; growing a pot of them at home adds a lot of atmosphere to your home decor and makes people feel very comfortable, but some friends find that as they grow them, their azalea leaves get more and more yellow, which is very distressing. Below, the editor will introduce the ways to solve this problem.
What to Do When Azalea Leaves Turn Yellow
1. Improper watering and fertilizing
If azaleas are watered too little or too much, or fertilized with too strong a dose or with undecomposed raw fertilizer, the leaves will turn yellow, and in severe cases the whole plant will die. Water and fertilizer should be applied appropriately; when water or fertilizer is excessive, you can repot and change the soil.
2. Soil and water too alkaline
If the potting soil is alkaline or the plant is watered with alkaline water for a long time, it will affect the plant's absorption of iron, causing iron deficiency and thus yellowing leaves. You can buy some ferrous sulfate and water the azalea with a 0.2% solution daily, or add a few drops of edible vinegar to the water used for watering to increase the soil's acidity.
3. Poor root absorption
When summer temperatures are high, the yellowing is especially obvious, and after the weather turns cool in autumn it improves somewhat or returns to green. For this kind of yellowing phenomenon, measures to protect and care for the roots must be taken. In winter, keep the temperature relatively high; in summer, when temperatures are high, provide shade, spray water to cool the plant, and maintain good ventilation to promote healthy growth and development of the plant's root system.
How to Solve Azalea Leaf Drop
1. Maintain the humidity of the air and potting soil, provide appropriate shade, and ensure air circulation; there is no need to rush to change the soil or fertilize. In winter, give it plenty of light; when growing it indoors, place it under a south-facing window as much as possible, and the ambient temperature must not be lower than 5 degrees. Do not move it around casually, to avoid sudden temperature changes. Also do not place it in a place with relatively polluted air.
2. The growing medium must be an acidic soil with good aeration and rich in humus, with a pH of 5.5 to 6.5 being most suitable. Usually, apply some alum fertilizer water appropriately, or add a little ferrous sulfate to the water when applying it. If alkaline soil is used, it will cause the leaves to yellow and drop.
3. When repotting, add an appropriate amount of controlled-release fertilizer to the potting soil (the fertilizer is coated with an organic film, and the fertilizer is slowly released through the film to supply the plant with nutrients); it is safe, clean, long-lasting, and produces bright flowers and lush leaves.
4. Take care to place the azalea in a spot with morning and evening sunlight and shelter from the wind for cultivation.
How to Grow Azaleas
1. Soil: Generally, the cultivation methods for plants and flowers cannot do without a good soil environment, and for azalea cultivation methods, the soil environment is even more important.
2. Watering: Watering is a very important task. For azalea cultivation methods, the techniques of watering are very important. When watering, water appropriately, and it is best to water in the morning and evening, which helps the azalea absorb water well.
3. Fertilizing: Azaleas are a very imposing flower and do not need much fertilizer to grow, so when fertilizing, be careful not to apply too much. Over-fertilizing will make it hard for the azalea to absorb nutrients and cause it to die; appropriate fertilizing is what allows the azalea to grow well and produce beautiful flowers.
4. Sunlight: Among cultivation methods, another very important and indispensable one is the absorption of sunlight. For plants and flowers, promoting photosynthesis is very necessary. Therefore, the growth of azaleas cannot do without sunlight either, but they cannot be exposed to the sun all day long; suitable sunlight can make azaleas produce even more beautiful and charming flowers.
Points to Note When Planting Azaleas
1. The growing medium must be an acidic soil with good aeration and rich in humus, with a pH of 5.5 to 6.5 being most suitable. Usually, apply some alum fertilizer water appropriately, or add a little ferrous sulfate to the water when applying it. If alkaline soil is used, it will cause the leaves to yellow and drop.
2. Azaleas do not like heavy fertilizing; once raw fertilizer or concentrated fertilizer is used, fertilizer damage will occur.
3. When repotting, add an appropriate amount of controlled-release fertilizer to the potting soil (the fertilizer is coated with an organic film, and the fertilizer is slowly released through the film to supply the plant with nutrients); it 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 with it have lush leaves and bright flowers. Azalea roots are slender; if the potting soil does not have good permeability or the plant is watered too much and too often over a long period, plus poor ventilation, the roots will be damaged, causing wilting leaves and leaf drop.
4. When watering azaleas, be sure to remember “water thoroughly when you water”; usually spray water on the leaves and around them to raise the environmental humidity.
5. Azaleas like light but fear the scorching sun; they like ventilation but fear strong winds. Placing them under the scorching sun in summer, or in a drafty spot in spring (especially early spring) and autumn, will cause a large number of leaves to drop. Take care to place the azalea in a spot with morning and evening sunlight and shelter from the wind for cultivation. The soil used for azaleas must have good permeability and be acidic.
What is provided above is some small tips for growing azaleas as well as the points to note. You can follow the methods above, but other situations may still arise during the process, so we should combine the theory above with the actual situation to find the most suitable method for growing them.
