What to Do When the Leaves of a Radermachera sinica Dry Up? Causes and Solutions

1. Causes

1. Normal metabolism

When an organism grows to a certain level, it will produce certain metabolic byproducts or show certain metabolic phenomena, and the Radermachera sinica (China doll) is no exception. When it grows to a certain extent, due to the continuous physiological reactions inside its body, a small number of its leaves will wither.

2. Improper watering

Improper watering methods may prevent the Radermachera sinica from growing normally. If it is watered too little, its leaves will dry up due to lack of water; if it is watered too much, waterlogging will affect the breathing of its roots and will also cause the leaves to dry up.

3. Improper fertilizing

Applying too much or too little flower fertilizer, or choosing the wrong type of flower fertilizer, can also cause the leaves of the Radermachera sinica to wither.

4. Root problems

The root system is the organ most plants use to absorb nutrients, and if there is a problem with it, the leaves will dry up. A newly purchased branch may be unable to absorb nutrients because it has no roots, which causes the leaves to dry up; improper operation when repotting may damage its roots and also make it unable to absorb nutrients, causing the leaves to dry up.

5. Improper air conditions

The air conditions mentioned here include two aspects: one is air humidity, and the other is air circulation. Whether the environment is too dry or too stuffy and poorly ventilated, the leaves may dry up.

6. Light problems

If the place where the Radermachera sinica is placed does not receive enough sunlight and cannot meet its needs for photosynthesis, it will also cause the leaves to dry up.

7. Pests and diseases

Some diseases or insect damage may also cause its leaves to dry up.

2. Solutions

The solutions are given one by one below according to the causes listed above.

1. Directly cut off the withered leaves and wait for new leaves to grow.

2. If it has been watered too little, replenish water in time; if it has been watered too much, take the plant out in time, remove part of the wet soil, mix in some dry soil, and replant it. After that, water according to the specific situation, ensuring that the soil in the pot is only slightly moist.

3. If too little fertilizer has been applied, supplement fertilizer in time; if too much has been applied, take the plant out in time and replace the growing medium. After that, apply flower fertilizer in an appropriate amount according to the actual situation. If the type of flower fertilizer is inappropriate, replace it in time.

4. A new branch can be placed in a suitable environment and left to wait for it to grow roots; if the roots have been damaged, do not water for the time being and wait for it to slowly recover before returning to normal care.

5. Spray some water mist into the surrounding environment to increase the water content of the air; place it in a place with air circulation.

6. Place it in a place with good light.

7. First cut off the diseased leaves and burn them, then spray the corresponding medicine. Usually, you can also spray some diluted medicine to prevent it.
