In the net red foliage plants, in addition to a variety of potatoes, vine green velvet and arrowroot, there is also a type of net red plants that are ignored by many friends, that is, leaf-viewing begonias, including common angel wings, trout begonias, small snails, rexes, painter palettes and silver language varieties.

Some flower lovers will say that these begonias are easy to die in the summer, in fact, because they are particularly afraid of heat, and they must learn to shade and cool them.
Begonia is a perennial herb belonging to the genus Begonia in the family Begonia, with a short plant that grows up to 30 to 60 cm tall.
Above are the Lig Begonias and the Begonias of the Four Seasons
Many friends know a variety of flowering begonia varieties, including the common four-season begonia, lig begonia, large-flowered begonia, bulb begonia and bamboo begonia. Now there are many begonia varieties on the market, most of which belong to hybrid breeding, that is, some native begonias are used as the father and new varieties as the mother, so that the hybrid can produce offspring that can grow normally.

Now there are still some friends who can't distinguish the difference between begonias and woody begonias (such as Begonia Xifu, Begonia weeping and begonias with longevity crowns, etc.), in fact, they are the difference between herbs and woody flowers (some friends joke that they are the difference between wives and wives), the former is begonia family, and the latter belongs to the rosaceae family, which is completely two types of plants.
Precautions for the conservation of begonias:
Begonias are mainly ornamental leaves, they can also flower, but the amount of flowers is very small, and the flower color is not very conspicuous, but the colorful leaves are more loved.
Many friends fail to maintain potted begonias, in fact, the environment at home is not suitable, they are afraid of high temperatures (especially stuffy environment), but also afraid of cold, many friends feel that these begonias are very delicate.
1, the appropriate temperature
The optimal maintenance temperature of foliage begonias is between 12 and 25 degrees, and the temperature is higher than 32 degrees, which is easy to rot the black rod. In the hot, humid and unventilated environment of summer, if the leaves are still often wet and do not pay attention to shade, these begonias are particularly easy to hang.
Begonia is very afraid of cold, and if the winter maintenance temperature is lower than 7 degrees, it is prone to frostbite (it can be frozen overnight). If the temperature is low and frequent watering, it will aggravate frostbite?
The peak growing season of begonias is in spring and autumn and winter, and in the summer heat, begonias will enter a semi-dormant or slowed-down state, especially after the temperature rises to 33 degrees.
2. Proper lighting
When we maintain potted begonias indoors, we can place them in the air-conditioned room in the summer, which can make them safe in the summer, and we can also move the potted begonias to a cool and ventilated position in the summer, which can give appropriate scattered light, and can even be placed directly in the shade of the tree, and there is more than 3 hours of soft light every day to meet its growth needs.
Begonias can tolerate a semi-shaded environment, but can not be raised in an over-shaded environment, in a bright light can not be raised in a good state, you need to ensure that there is more than 3 to 6 hours of oil and scattered light every day, in order to ensure that they grow healthy.
In the cold season, the temperature between 5 and 22 degrees can be more sun, avoid the sun exposure. If it is in the high temperature season, it must pay attention to shading maintenance, and often spray water on the ground to reduce the ground temperature.
3. Suitable potting soil
Loose, breathable, well-drained soils for the planting of potted begonias, such as the common peat soil, fine coconut bran and coarse coconut bran, mixed in a 5:3:2 ratio, can be sprinkled with a little slow-release fertilizer in the potting soil.
When planting potted begonias at home, try to avoid the use of organic fertilizers, because organic fertilizers are easy to breed diseases and insect pests in a poorly ventilated environment.
4. Precautions for fertilization
To raise potted begonias, you only need to sprinkle some slow-release fertilizer on the potting soil in the spring and autumn. If the temperature can be maintained between 15 and 25 degrees, you can supplement the water-soluble fertilizer every 10 days or so, such as the common flower More No. 1 or HuaDuo No. 2, which can be sprayed alternately, which can not only promote long leaves, but also make the leaves grow more colorful, and occasionally you can also open a little flower.
However, be careful not to give fertilizers that only nitrogen, and do not give too much nitrogen too much fertilizer, otherwise it will lead to the degradation of leaf markings.
Wait until late spring, or in the summer and autumn seasons with higher temperatures, when the temperature exceeds 25 degrees, stop fertilizing.
Many flower lovers raise potted begonias to see the leaves of the begonia will appear rotten roots, black rot, rotten leaves, etc., most of them are due to the environment is sweltering, high temperature exposure, excessive fertilization, poor environmental ventilation, or long-term humidity of the potting soil caused.
5. Pay attention to watering
Leaf-viewing begonias prefer large water, after the cultivation of pots, do not let the pot soil completely dry and then watered, that will definitely lead to plant wilting (especially when there is more sunlight), and even the plant wilting.
When the environment is good, generally wait for the topsoil to dry, you can water it once in time, touch the lower soil before each watering, and then water the soil when the soil is relatively dry.
6. Humidity and ventilation
Conservation of leaf begonias should also pay attention to maintaining a certain air humidity, to avoid excessive drying of the air, the relative humidity is best maintained at more than 50%, but if it is in a sweltering environment, the environment ventilation is not good, then do not always spray water on its leaves, do not let the leaf surface often remain water, otherwise it is easy to cause begonias to be infected with germs, including common rhizome rot or leaf spots.
Begonias prefer higher air humidity, can not be overly dry environment, can occasionally spray water around, can increase the environmental humidity. But don't always spray water on its leaves, and the leaves can't be left with water for a long time.
You can put some pottery or pebbles at the bottom of the pot, add a little water, the water level does not cross the stone, and then place the pot on the stone, you can continue to increase the humidity, but not to make the pot soil wet for a long time.
If the environment is not well ventilated, after spraying water on the leaves, the water cannot be volatilized in time, and it is easy to be infected with germs. If the water can evaporate within 1 to 2 hours after spraying water on the leaves, you can occasionally spray water on the leaf surface.
7. Prevention of fungal diseases
Begonias that conserve foliage are more susceptible to fungal diseases, including common leaf spot disease, gray mold and root rot. Usually pay attention to reasonable watering, improve environmental ventilation, give more soft scattered light, but also pay attention to spray it every once in a while, generally sprayed every 20 days, you can use the common phenoxymethaclazole, oxanthin or putrex and so on. When spraying, pay attention to the uniform spraying of the leaf surface and the back of the leaf, and can also be used to irrigate the roots, and 2 to 3 kinds of alternating spraying can be used to avoid drug resistance.
Other common fungicides, such as methyl thiopheptam, methyl tolbuzin or bacillus, can be used occasionally and can play a certain preventive effect.
summary:
In general, the most important thing to do in potting and planting foliage begonias is to maintain a suitable temperature, give soft scattered light, water reasonably, ensure that the soil is loose and breathable, and regularly spray fungicides to raise begonias well.
