1, root rot. The main cause of root rot is excessive watering, or poor drainage of pots and soils, and long periods of stagnant water that are not breathable, resulting in the inability of the roots of the camellia to breathe. As a result, the roots are rotted.
To solve this problem, it is best to remove the plants from the pots, remove the peripheral soil, cut off the rot from the base with scissors, and then disinfect the wound with 0.1% potassium permanganate solution or use clean grass ash. Apply the wound and replant it or plant it under the ground.
2, can not fall leaves, pruning dead. This phenomenon is mainly caused by long-term use of tap water irrigation tea leaves, so that potting soil alkaline and compaction, resulting in the plant's root water absorption function is blocked, branches and leaves withered due to water loss caused by the death of the whole plant. Or the sun exposure, or in the bud period, light conditions and other sudden changes, camellias is difficult to adapt to this change, there will be no leaves, pruning dead phenomenon.
Therefore, the problem of watering the camellia is of utmost importance. It must not be sloppy. The best water is rain, pond water, and tap water must also be sun-dried in the sun for three to five days. Then add a little ferrous sulfate. In the seasons of spring, summer and autumn, the camellia should be moved to the shade to feed them. Indoor winter viewing, we must pay attention to the humidity of the air, the temperature is too dry, the same will make the camellia leaves the pruning dead.
3, planting tea flower pots basin drainage holes can not be blocked. The best selection of tile pots, this type of pot permeability. The soil is better with slightly acidic mountain mud, and the mud is the worst. It must be reminded that the soil used for the cultivation of camellia should be high in water-holding capacity. Absolutely no soil with strong water permeability, such as pine needle soil, should be used.
4, once a year, turn over basins, turn basin time in the spring after Xiehua.
5, high temperature and winter indoor dry season, should be ground water spray to the camellia. When water is sprayed, edible vinegar can be dripped in the water, which can not only clean the leaf surface, but also increase the acidity of the basin soil and avoid the yellowing disease.
