What to do about yellowing and falling leaves on a Radermachera sinica? Water it with this kind of water in summer, and it will recover its glossy green in 3 days

Radermachera sinica yellowing and falling leaves

1. Too much watering, leaves rot and fall

Radermachera sinica likes a relatively humid environment, but if you water too much, or the potting soil is compacted so water does not penetrate, it is easy for the roots and leaves to rot.

Solution: Control watering. Before watering, check whether the potting soil is dry. For a money tree that has already been flooded, it is best to take it out of the pot and let it dry for a day, then dry it and put it back in the pot. If the potting soil is severely compacted, you can use a bamboo stick to poke some holes along the edge of the flowerpot, and wait until the weather cools down before changing the soil.

2. Not enough watering, drying out and dropping leaves

In summer, evaporation is high. If you do not pay attention to watering it for three to five days, the Radermachera sinica will immediately wilt, and the leaves will fall in droves. Look at the fallen leaves, are they dry?

Solution: Water thoroughly right away. Ordinary flowerpots have holes at the bottom. Watering thoroughly means watering until you see water flowing out of the small holes. After watering, let it rest for half a day to see whether it recovers.

If the situation is relatively serious and most of the leaves have already dried up and fallen, it is best to cut the Radermachera sinica bare, soak the flowerpot in a basin of water for 20 minutes, then place it in a cool, ventilated place to recover for 3-5 days. If new buds appear, it has survived.

3. The weather is too hot

Once the temperature exceeds 32°C, Radermachera sinica tends to wilt. That is a distress signal, and you must pay attention.

Solution: "Take off its clothes" and prune the Radermachera sinica all over so it can dissipate heat better. Do not be reluctant to do it. The more you prune Radermachera sinica, the faster it grows. One month after pruning, it can grow back to its original appearance. If you do not believe it, try it!

4. Exposure to strong sun or lack of sunlight

Summer light is relatively intense. Many flower lovers like to put Radermachera sinica near the glass window of a balcony. If the sunlight is strong in this position, it is simply grilling the Radermachera sinica. Conversely, if you move Radermachera sinica to a dark corner in the house, where both light and ventilation are poor, it is also prone to yellowing and falling leaves.

Solution: Move it indoors to a place with balanced light, preferably a semi-shaded place. Huahua suggests placing it on the north side of the living room sofa. If the temperature at home is still too high, or if the air conditioner is on, you can spray water around the leaves of the Radermachera sinica, which can both lower the temperature and increase humidity.

5. Pests and diseases

Scale insects and aphids are the natural enemies of Radermachera sinica. Once these small insects infest it, they are not easy to completely eliminate and always recur.

Solution: Flower lovers who have professional insecticides at home can spray some Jiebi Si, zinc phosphide, or Jiebi Zhi. It is best to spray after 3 p.m. Move the Radermachera sinica outdoors, wear a mask well, and spray both sides of the leaves with the medicine.

Huahua also has some homemade insecticides here. Put pure milk in a small spray bottle and spray it on the leaves with insects. After 2 hours, wipe them clean with clean water. Wiping with alcohol can also kill insects. Mix laundry detergent with hot water evenly, let it cool, then spray it on the insect-infested leaves. After 1 hour, wipe them clean, and that also works.

Grown this way, Radermachera sinica becomes green and strong

1. Sufficient light, controlled watering, and ventilation

Radermachera sinica cannot be grown in shade. The location must have bright light. Do not water too frequently. Water thoroughly only after the potting soil is dry. This can stimulate Radermachera sinica to keep producing new leaves.

2. Proper pruning

Radermachera sinica is very prone to leggy growth. If your Radermachera sinica has new branches stretching out very long, there is no doubt that it is leggy. Hurry and prune off half so it grows into a ball shape.

3. Fertilizer water and foliar fertilizer

The leaves of Radermachera sinica are the main feature. Air conditioner condensate water and fish tank water can both be used as fertilizer water. Usually, you can also spray some beer water (beer after being left open to release gas, mixed with water = 1:20), which can make the leaves green and shiny and keep growing like crazy.
