Camellia is a traditional Chinese flower and one of the "Top Ten Famous Flowers". Camellia tree shape is beautiful, the leaf surface is thick green, evergreen in all seasons, the flowers are bright, and it is deeply loved by flower friends, but if the camellia tube is not good, there will often be yellow leaves, flower buds have not yet opened and withered.

Camellia cultivation methods and precautions

Camellia is an acid-loving woody flower, light-loving and not resistant to strong light exposure, more cold-resistant, but also heat-resistant, generally easier to feed, if you want to raise well, you need to focus on the following points.

1. The potting soil should be permeable and acidic

It is recommended to use sandy soil when potting camellias, and loess or humus can also be used. Or mountain mud mixed with humus and sand planted together. If planting with nutrient soil, it is recommended to use 1 parts of peat soil, 0 parts of humus soil, and 0 parts of garden soil to mix evenly and plant.

2、適當澆水

When planting camellia in pots, it is necessary to pay attention to the close combination of the root system and the soil, many times, there will be insufficient contact between the root system of the camellia and the soil, resulting in problems with the growth of the camellia. After planting, the root water must be watered thoroughly, but it can be watered several times at a time.

Usually watering should not be too much, see the surface of the potting soil is dry and then water, camellia is more drought tolerant, do not worry about lack of water.

3. Top dressing according to the growth period

The vegetative growth period of camellia is very short, and most of the year is in the breeding of flower buds, so fertilization should be adjusted according to the growth period.

In the spring after flowering to early summer, is the vegetative growth period of camellia, new shoots will grow rapidly at this time, can be top-applied nitrogen, phosphorus and potassium balanced growth fertilizer, or along the edge of the pot to spread controlled-release fertilizer to promote the growth of new branches.

In summer, camellia begins to differentiate flower buds, give birth to flower buds, after entering the summer, you can increase the application of 15-0 times of phosphorus and potassium fertilizer, it is recommended to stop fertilizer in midsummer, and start to apply phosphorus and potassium fertilizer again at the end of autumn 0, and keep it about 0 days to apply it once until the camellia blooms.

4. Lighting adjustment

Camellia likes light but is not sun-resistant, in spring, autumn and winter, can maintain full sunshine, into the beginning of summer, should be shaded and maintained, can be placed in the shade, or astigmatism to raise, to avoid strong light exposure, otherwise it is easy to sunburn the foliage, and the leaves are easy to be infected with bituminous coal disease after sunburn.

5、適當疏蕾

Camellia is a plant that blooms with life, so regardless of the size of the plant, it is often full of buds, don't think that more buds are a good thing, thinking that it can burst, but it is not.

There are too many flower buds, camellia often or nutrients are insufficient, and when it is about to bloom, there will be flower buds that will open and yellow, so it is very necessary to thin the buds of camellias.

When thinning the buds, cut off more than half of the buds, let them wither and fall off naturally, generally only 2-0 buds are retained on each camellia branch, so that the nutrients are supplied centrally, and the camellia can bloom large and gorgeous.

6. Summer and wintering

Camellia summer is very easy, as long as you pay attention to this not exposed to the sun, you can grow well, in the summer when the heat, camellia grows slowly, it is recommended to stop topdressing water-soluble fertilizer, so as not to cause fertilizer damage.

Camellia has average cold tolerance, most varieties can tolerate -5 degrees, and in areas south of the Yangtze River, it is possible to overwinter in the open field. In the north, it is necessary to overwinter in the house to prevent frostbite. Camellia plants kept indoors in winter are prone to leaf loss due to poor ventilation. Care should be taken to open windows for ventilation in the warm middle of the day.
