What are the key points to note when growing camellias?
Camellia is also called tea flower. It is an evergreen shrub of the genus Camellia. Camellia has high ornamental value and is cultivated in varying areas across China. In addition, camellia also has extremely high practical value. The camellia oil in our daily lives is extracted from camellia seeds. It also has certain medicinal value and is a flower with relatively high economic value. Today, what I want to introduce to you are the key points to note when growing camellias. Let us take a look below!
1. Temperature
Camellia has relatively high temperature requirements. It is a temperature-loving plant, and around 22°C is the most suitable temperature range for camellia growth. Unsuitable temperatures can inhibit camellia growth. Especially when the temperature is extremely low in winter, it is essential to increase the temperature in time, otherwise it will cause the camellia plants to suffer cold damage and die. However, in summer, direct sunlight on the plants should also be avoided, and proper shading should be done.
2. Soil
Because camellia is a fertilizer-loving flower, when growing camellias, the garden needs to be established on soil with sufficient fertility and a loose, deep texture, with a soil pH of around 6. It must not be alkaline, as alkalinity is not conducive to camellia growth. Choosing good soil and then establishing the garden is the first and also a relatively important step in growing camellias. This is because whether the soil is chosen well or poorly is directly related to the subsequent growth capacity of the camellias.
3. Topdressing
Camellia relatively loves fertilizer and has a large demand for fertilizer nutrients. During the growing process, topdressing should be done in time according to the growth condition of the plants. During the vigorous growth period of camellia, the proportion of phosphorus and potassium fertilizer should be increased, which helps promote camellia growth and increase the flowering rate of camellia. However, when fertilizing, attention must be paid to the amount and nutrient ratio. Too much or too little will have a relatively large impact on camellia growth.
4. Water
Camellia has a particularly large water requirement throughout its growth period. It likes to grow in a humid environment, so during the growing process, it is essential to ensure sufficient water to support camellia growth. However, water should not be excessive either; keeping the soil moist is enough. But in hot and dry weather, watering should be done in time, because when the temperature is high, the evaporation rate of water will also accelerate, so timely water replenishment is very important. On the contrary, in a low-temperature environment, the watering frequency can be appropriately reduced.
5. Pruning
Proper pruning is also a very important task in cultivation. During growing, the growth condition of the camellias should be observed at all times. There should not be too many flower buds on the plants. Just like growing fruit, too many fruits should not be left, because the plant's bearing capacity is only so strong. Too many flowers not only consume excessive nutrients, but also affect the flowering rate. Therefore, weak branches and excess flower buds should be cut off in time to concentrate nutrients on the other flower buds.
The above is a brief introduction to the key points to note when growing camellias. Camellia cultivation is very common in China, and there are also specialized cultivation bases. In fact, there is one more point we should especially pay attention to, and that is the prevention and control of pests and diseases. The harm from pests and diseases can be devastating to camellias. So everyone must pay attention. That is all for today's introduction. This article is for reference only. Thank you all for reading and supporting.
