How to maintain in summer h2>
1. Post flower pruning
After the camellia flower withers, we must cut off the flowering branches to reduce nutrient consumption. In addition, we should sparse branches and loose branches, cut off too dense overlapping branches, tangled branches and dead branches, ensure ventilation, and prepare for the next round of flowering p>
2. Watering
Camellia likes to be wet. The water evaporates quickly in summer. We must water more. However, it should be noted that when the soil on the basin surface is obviously dry, it can be watered thoroughly. The watering time should be 7-9 a.m. and 18-20 p.m. every day p>
3. Illumination
The temperature is too high in summer, so Camellia can't be exposed to the sun for a long time. If the outdoor maintenance exceeds 30 degrees, it should be shaded, and the indoor maintenance should be placed at the scattered light p>
4. Fertilization
Camellia likes fertilizer. After flowering, rotten cake fertilizer water or phosphorus potassium compound fertilizer should be applied every 1 week, and thin fertilizer should be applied frequently. But after dormancy in summer, stop fertilization p>
What problems should be paid attention to in summer maintenance h2>
1. Soil management
It is best to arrange the soil on the basin surface into an inclined basin surface with a high basin edge and a slightly concave flower stem base, which can effectively prevent the root soil from drying into a lump and the root can fully absorb water. In rainy days, the accumulated water in the basin shall be poured out in time to prevent large root rot p>
2. Proper water control
Camellia generally has the second flower bud differentiation in July. After new leaves grow, water should be properly controlled and the soil should be kept slightly dry in late August, which is conducive to promoting the stout and lignification of new branches and promoting buds p>
3. Don't move your position often
Often moving the flowerpot and changing the growth direction and light receiving surface are conducive to the formation of beautiful plant types for other flowers. However, Camellia has poor adaptability and often changes its position, which is easy to grow poorly, withered leaves and fallen leaves, and even hurt the root system in serious cases, especially in high temperature seasons p>
Common pest control
Common diseases
Anthrax
From June to July is the high incidence period of Camellia anthracnose. Yellowish brown spots will appear on the infected leaves and spread gradually. Once found, the diseased leaves shall be cut off immediately. Spray 600 times of chlorothalonil water solution once a week or 1% Bordeaux solution once a half month for 3 ~ 4 times continuously p>
Root rot
Camellia root rot is characterized by root rot, blackening, yellow leaves, dry tips and falling flower buds. After root rot is found, the plant shall be dug out immediately, the rotten root system shall be cut off, disinfected with diluted potassium permanganate solution, and the soil basin shall be replaced again p>
Common pests
Scale insects and aphids
In muggy, hot and humid weather, scale insects and aphids are easy to parasitize on the branches and leaves of Camellia. You can kill them with pyrethroids or inhalant insecticides diluted 1000 ~ 2000 times. Spray them once a week and spray water once after spraying p>
Starscream
If there are grayish yellow spots on the leaves, timely check whether there are red spiders on the back of the leaves. To eliminate red spiders, spray the whole plant with 40% dicofol emulsion 1000 ~ 1500 times, once a week p>
