Why Does a Azalea Keep Losing Its Leaves? Causes and Solutions

The azalea, also known as the "ying shan hong" (mountain azalea), symbolizes passionate enthusiasm and the spirit of unremitting self-improvement. In addition, between lovers, the azalea's flower language also carries the meaning of "forever yours," so many couples give each other a bouquet of azaleas on special days.

Below we discuss why, in the daily process of caring for azaleas, gardeners often report that the azalea's leaf drop is very severe, and what the causes are. In fact, the frequent falling of azalea leaves can be roughly divided into several major categories. The first is soil choice: azaleas like acidic soil, so if the soil used for planting is on the alkaline side, then the azalea is very likely to drop its leaves. At this point, it is recommended to buy some acidic soil online for planting.

Azaleas also have requirements for their living environment: they like to grow in a semi-shaded, well-ventilated environment, and exposure to blazing sunlight should be avoided. In addition, where watering is concerned, the soil's moisture must be maintained, yet the plant must not be overwatered. During planting, it is recommended to pay more attention to the azalea's leaves; if the leaves look dry and withered, you can water it to maintain moisture. Of course, the pot used for planting azaleas should not be too large either, because if it is too large, waterlogging easily occurs.

In addition, in most cases where azaleas drop their leaves, the azalea has developed root rot. Because root rot also affects the branches and stems, causing them to fall off and rot. If root rot is discovered, it must be dealt with promptly, and the rotten roots must be completely removed. During the cleanup, you can cut away the rotten roots, then soak them in a carbendazim solution and rooting water; once the water has been absorbed, replant them. In winter, you should also pay attention to keeping azaleas warm, to prevent them from suffering cold damage.
