This flower will be decapitated in hot weather, cut a few knives to make up some water quickly, and burst the basin after autumn!

How to maintain in summer?

1. Pruning after flowering

After the camellias fade, be sure to cut off the failed branches to reduce nutrient consumption. In addition, to sparse branches and scattered branches, cut off overdense overlapping branches, tangled branches, dead branches, to ensure ventilation and ventilation, in preparation for the next round of flowering!

2. Watering

Camellias like to be wet, and water evaporates quickly in summer, so you must water more. But should pay attention to wait until the basin soil is obviously dry before watering, watering thoroughly. Watering time should be 7-9 a.m. and 18-20:00 in the evening.

3. Lighting

Summer temperature is too high, camellias can not bask in the sun for a long time, outdoor maintenance more than 30 degrees to shade treatment, indoor maintenance should be placed in scattered light.

4. Fertilization

Camellia like fertilizer, after flowering every week or so to apply mature cake fertilizer or phosphorus and potassium compound fertilizer, thin fertilizer is applied frequently. But after summer dormancy, stop fertilizing.

What problems should be paid attention to in summer maintenance?

1. Soil management

It is best to arrange the basin soil into an inclined basin with a high edge and a slightly concave base of the flower stem, which can effectively prevent the root soil from drying into a lump, and the root can fully absorb water. Pour out the stagnant water in the basin in time on rainy days to prevent the water from rotting the roots.

2. Proper water control

Camellia will generally differentiate flower buds for the second time in July, and 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 sturdiness and Lignification of new branches and promoting buds.

3. Don't move your position often

Often move the flowerpot, change the growth direction and light surface, is conducive to other flowers to form a beautiful plant type, but camellia adaptability is poor, often change the position, easy to poor growth, withered leaves, serious will also hurt the root system, especially in the high temperature season.

Control of common diseases and insect pests

Common diseases

Anthrax

From June to July is the high incidence period of camellia anthracnose, the infected leaves will appear yellow-brown disease spots, and gradually spread. As soon as it is found that the diseased leaves should be cut off immediately, spray 600 times chlorothalonil solution once a week or 1% Bordeaux solution every semimonthly for 3 or 4 times in a row.

Root rot disease

The root rot of camellia is characterized by root rot and blackening, yellow leaves and dry tips, and flower buds falling. After the root rot is found, the plant should be dug up immediately, the rotten root system should be removed, disinfected with diluted potassium permanganate solution, and the soil should be changed again.

Common insect pests

Shell insects, aphids

In muggy and humid weather, the branches and leaves of camellias are prone to parasitic scale insects and aphids, which can be killed with pyrethroids or internal insecticides diluted 1000 to 2000 times. Spray once a week, and spray water after spraying.

Red spider

When it is found that there are gray-yellow spots on the leaves, it is necessary to timely check whether there are red spiders on the back of the leaves. 40% diclofenac EC 1000-1500 times the solution can be used to kill the red spiders, spray the whole plant, once a week.
