Through the mutual communication with the flower friends, Huahua summarized nine reasons why the camellia lost its leaves and buds.
1. The lack of water in the root will lead to the falling of leaves and buds.
2. Standing water and rotten roots will leave leaves. Large flowerpots, frequent watering, and long-term over wetting of the root soil will lead to rotten roots and leaves of Camellia.
3. The lack of nutrition leads to the loss of buds. In spring and autumn, the best fertilizer is organic fertilizer, and the content of nitrogen, phosphorus and potassium is rich.
4. Excessive fertilization will lead to the loss of buds. Camellia likes to be thin and thin, and can only be applied if it is thinly diluted.
5. The newly purchased Camellia should first adapt to the humidity, temperature and environment at home, and then change the basin. It is better to buy Camellia in spring, so that there will be no falling leaves and buds.
6. After the flower bud of camellia is hit, the leaves covering the flower bud can be pinched off to let the flower bud receive sufficient light.
7. If there are too many flower buds, you need to remove some and leave the ones with good light on the top. Otherwise, if the nutrients are not enough, you will lose the flower buds.
8. When there is a lot of rain in the south, the flowers will fall off within a few days. Remember to cover them with plastic for a few days. In the dry weather in the north, you can also cover them with plastic bags for heat preservation and moisture preservation.
9. It is not ventilated and the temperature is too high. Especially in winter, when camellia is kept indoors for a long time, the air is dirty and the temperature in the heating room is over 20 ℃, the leaves and flower buds will fall.
When buying camellia, you should choose healthy branches and leaves without obvious diseases and insect pests. When you just buy camellia, you must not wash the roots, remove part of the surrounding soil, and leak out a little root system to cultivate it in the original ball. This way, the survival rate is very high.
If you are curing outdoors, you can use yellow mud or red soil, and add some river sand. This kind of plain soil is very good for its root system. It is exposed, ventilated, and not afraid to clog the root.
It is recommended to raise Camellia indoors: coconut bran 1, peat soil 1, sandy laterite 2. If there is microbial agent, it can be added a little to increase soil activity.
Note: do not use too much nutritious soil!
It is the first time to pour water into the basin and put it in the place of astigmatism and ventilation. After that, when the basin soil turns white and 2cm below the basin surface is dry, it can be poured; those raised in the open can be poured in more than once.
After entering the room in winter, the growth rate slows down. Try to dry it thoroughly before pouring.
Autumn and winter are the growing season of tea flower bud, so the light must be sufficient. It's good to have more sunshine. In spring and summer, the scattered light is accepted. Don't sun the newly potted tea flower.
The family raises camellia, use these kinds of fertilizer commonly:
Bean cake or sesame cake; huaduo No. 1 and No. 2; aolvfei, potassium dihydrogen phosphate.
Huaduo No. 2, soybean cake and potassium dihydrogen phosphate were used alternately in different seasons, and huaduo No. 1 or soybean cake fertilizer was used in January in winter and before sprouting in spring.
In winter in the north, Camellia must be placed in a low temperature environment. If the temperature is over 15 degrees, it will fall, and it should not be too low to cause frostbite.
In addition, don't open the window on the balcony, just leak a seam. The dry and cold northeast wind is the killer of Camellia.
