What should I do if the azalea leaves dry up and fall off at the slightest touch? Find a solution in 2 minutes
Azaleas make many flower enthusiasts love and hate them. Why is that? Love is because the blooming of azaleas is really beautiful, and the flowering period is also very long. Hate is because many flower enthusiasts think that azaleas are really difficult to grow, easily turning yellow, shedding leaves, and withering. Is that really the case?
The cultivation history of azaleas dates back over a thousand years, and the great Tang Dynasty poet Bai Juyi was particularly fond of azaleas.
In fact, growing azaleas is not that difficult. The reason why many flower enthusiasts encounter many problems with yellowing and shedding leaves is mainly because of a few aspects that are not handled well. Let's make a summary here, hoping it will be helpful to you in growing azaleas.
Reason for yellowing leaves 1: No new roots
Many flower enthusiasts buy azaleas and plant them directly into new pots with the original soil ball. After the flowers bloom in the spring, they will find that the leaves of the azaleas begin to show dry tips, slowly wither, and eventually, only the stems are left, and then the stems wither.
Have you encountered this situation too? In fact, this is because the root system of the azaleas has not grown. Although they can bloom normally, blooming has already consumed a lot of nutrients, and the nutrients in the original soil ball have also been depleted. With no new roots growing and old roots being moist and闷 for a long time, the old roots will slowly rot, so after the spring flowers, the azaleas begin to wither slowly.
The best solution for this situation is to handle the root system when planting the azaleas.
The azaleas we buy often have the entire soil ball completely wrapped with roots, but there are rarely any new roots among these roots. These roots grow together, and when planted directly due to the difference in soil matrix, it is difficult for new roots to germinate, so the root system should be handled first before planting.
Remove the soil from the outer circle of the original soil ball of the azalea, allowing the roots to have a small number of断面, making the roots loose, and only with断面 can stimulate the growth of new azalea roots. After handling it this way and then planting, it is easier for azaleas to grow new roots.
Reason for yellowing leaves 2: Iron deficiency
Sometimes we find that even though the root system of the azalea has been treated when planted, it is still prone to yellowing leaves during the cultivation process. Why is that?
This type of yellowing leaves can be seen as new leaves turning yellow, which is a typical symptom of nutrient deficiency, specifically iron deficiency.
Azaleas are typical acid-loving flowers. When grown in pots, the soil often becomes alkaline, affecting the absorption of iron by the azaleas. When azaleas show new leaves turning yellow due to iron deficiency, you can apply chelated iron foliar spray to supplement iron. At the same time, add a small amount of ferrous sulfate fertilizer to the water when watering to adjust the soil pH and supplement iron.
Reason for yellowing leaves 3: Excessive sunlight
Sometimes, even though we take good care of them, we still find in the summer that the leaf tips of the azaleas are prone to drying out, and even some yellow spots appear on the leaves. This time, we need to consider the issue of sunlight.
Azaleas are not sun-tolerant and prefer shade. In the summer, you must shade the azaleas or place them under the tree shade. Excessive sunlight, especially strong direct sunlight, can easily cause sunburn and yellowing leaves and shedding.
Reason for yellowing leaves 4: Leaf blight
If your azaleas can rule out root causes and lighting issues but still show dry leaf tips, then it's time to consider the possibility of disease.
Azaleas are prone to leaf blight, especially in indoor balconies with poor ventilation, where the likelihood of disease increases significantly. Therefore, if your azaleas show dry leaf tips and can rule out root and lighting causes, it is likely that they have leaf blight, and it is recommended that you use a fungicide spray for treatment.
The cultivation of azaleas is actually quite simple. Once you master the rules, everything becomes easier. The difficulty is mostly due to a lack of understanding of the cultivation methods and not knowing the causes of the problems.
