The reasons for leaf loss are generally the same, such as lack of light, too low temperature, too much watering, and insufficient fertilization.
1. Lack of light.
Its origin is in the tropics and requires high light. If there is a lack of light in the breeding process, photosynthesis cannot be carried out, and the leaves will become dull and dull after a long time, and they will fall off in severe cases. Most of the old leaves fall, and the new leaves do not fall.
If you find this situation, you should move it to a well-lit place outdoors as soon as possible, and rotate the direction of the pot regularly to ensure that the light is evenly received, so that the treated plants will slowly recover.
Second, insufficient fertilization.
It is more fertilizing, and if the plant does not have enough nutrients during the maintenance process, it will lead to poor growth and will also lose its leaves. To replenish in time, it is recommended to supplement fertilizer every half a month in the peak growth season, and the fertilizer should be diluted with compound fertilizer, such as Bika water-soluble fertilizer, thin fertilizer is applied frequently, so as to ensure that the nutrients are sufficient, and the growth of the plant will be more luxuriant.
3. Hypothermia frostbite.
Plants in the tropics naturally prefer warm environments and are not hardy. During the maintenance period, we must pay attention to the low temperature in winter, and the temperature should not be lower than 15 degrees, otherwise it is easy to frostbite the plant and fall leaves. After cooling down, move indoors and control the temperature to about 18 degrees.
Fourth, watering too much.
It has a certain drought tolerance, if the management period of frequent watering, the plant is difficult to absorb all the roots, a long time will be roots, rotten roots, can not normally provide water and nutrients to the leaves, naturally will yellow leaves, defoliation. The amount of watering should be reduced, and it is recommended to use the method of watering with dry and wet watering. If the leaf fall is serious, it is necessary to depot, prune rotten roots, and dead roots.

There are mainly the following reasons for the defoliation of variegated wood: (1) Variegated wood is not cold-tolerant and is susceptible to frost damage in winter, and the indoor temperature should be above 15. When the temperature is low, the leaves will fall off a lot, in this case, you can reduce watering to ensure that the potting soil is slightly dry.
After leaving the house in the spring of the next year, change the pot and replant it, and re-prune the branches, and the growth can be resumed. (2) In summer, the strong direct light causes the leaves to lose color and cause leaf fall. (3) Variable leaf wood is not drought, and long-term lack of water in the potting soil can easily lead to leaf litter.
4) The more years are not pruned, which causes the aging and defoliation of the plants. (5) Insufficient nitrogen fertilizer in the peak growth period caused defoliation. (6) Scale insects or red spiders are infested.

Most likely is too much water, give less, although it is said that you like high temperature and high humidity, humidity can be sprayed, do not use more, if the pot has a pot, pour the excess water inside, watering not too much......

Variegated wood likes high temperature and high humidity environment, grows well above 35 degrees, does not ventilate, low temperature, weak sunlight, and water are mostly the causes of leaf loss, as for whether there are carcinogens, according to the data.
Cuttings are made from 1-2 year-old branches, cut into about 10 cm branches, and cut into cuttings to take root in sand or soil. The strip is in the plant growth period when the branches are soft, bent downward, and buried in the soil after the horizontal peeling of the bud eye, and after a period of time, new roots will grow, which can become a new plant. [There is also the high branch strip method] above is asexual reproduction.
Sowing is the sowing of seedlings and multiplication after the seeds produced by the father and mother plants through natural pollination or artificial pollination are matured, and sowing is sexual reproduction.

It's too cold, below 15 degrees is not long, below 10 degrees is in danger of freezing to death.
-
Although the leaf color is rich and the ornamental value is very high, this plant is not suitable for indoor potting, mainly because the species has a strong tumor (what we call cancer) induction, experiments have shown that even the soil that has been planted with this plant will have residual tumor inducing factors, so if it is an indoor potted plant, simply give up, if you live in Hainan, plant it in the courtyard, preferably by the pond (this plant likes heat and humidity), but for the sake of health, I still recommend that you abandon it.

Is air pollution carcinogenic? Don't gasp, okay?

In the past, watering was a little bit of roots, put it on the balcony in a bright and ventilated place, dry and watering, the soil is not dry and not watered, it doesn't matter if the soil is dry, afraid of waterlogging,
-
There are many reasons why the leaves of the leaf tree are easy to fall, such as too frequent watering, excessive fertilization, too dark light, and spider mite damage.
Variegated wood is not resistant to drought because of water, but it is also not resistant to long-term waterlogging, watering should not be too diligent, and the substrate for cultivating variegated wood is peat soil, which can be watered after the topsoil is dry.
Fertilization should be done in small amounts and many times.
At this time, the light should be scattered, and sufficient light should be given in winter, early spring, and late autumn.
After the damage of red spiders, it is easy to drop leaves or fall when touched, and special pesticides should be sprayed to prevent and control them, such as dicofol, nisolan, etc.

The water is big. You can't water once a day, you have to look at the surface of the potting soil, and the surface is dry and watered thoroughly at one time.
If your tree is kept at home, it will easily cause the leaves to yellow and fall off when shaken. This is a lack of photosynthesis, it is better to move the tree to a sunny and ventilated place, after a period of yellowing, the situation of leaf loss will improve. My two lacquer trees used to be in the same situation as you, but after moving downstairs to raise them, they are much better, and now they are growing very luxuriantly, and the new shoots are also very strong.
First, the light is too strong.
1. Reason: Rhododendron likes sunlight, but it can't tolerate long-term strong light exposure. If you put it in a position with too much light when raising it, it may cause the leaf tip to dry out and turn brown. >>>More
Rhododendron cultivation precautions:
1.The rhododendron's roots are as thin as a hair, and the thick taproots are few, and it is afraid of both dryness and wetness, especially heavy fertilizer. If you water too much, the roots will be soaked in water, too dry, the branches and leaves will shrink, and the leaf petals will fall off, which is a great threat to the plant, and as for watering heavy fertilizer, it will be life-threatening. >>>More
1. Cuttings: Its propagation is often carried out by cuttings. It's in spring or autumn. >>>More
1. Watering: It has high requirements for water volume. It is more drought-tolerant, but it needs a lot of water, not only in April and September, but also to spray some water on its leaves, but not to cause stagnant water, otherwise the roots of the plant are prone to rot. >>>More
