How to properly care for camellias
Let me tell you about how to care for camellias, the methods, and precautions related to green plants and flowers. Let's take a look together!
Camellias, also known as wild camellias, come in a variety of colors, including red, purple, white, and yellow, making them quite ornamental and popular among many people. So, do you know how to care for camellias? What should you pay attention to in daily maintenance? Let's find out below.
1. Acidic Soil
If the branches of camellias grow slowly, produce few flowers, and do not grow in size, it is likely that the root system is not well-developed. The most crucial factor for root growth is the soil. Generally, poor and compacted soil is not suitable for camellias. To care for camellias well, choose slightly acidic soil, so you can add a lot of decomposed leaf mold or well-fermented pine needle soil to the soil where camellias are grown.
2. Sufficient Light
Camellias enjoy light, and they can be exposed to plenty of light in any season except summer. This will help them grow well. In summer, make sure to provide shade, as placing them in a diffused light or half-day lighting environment is sufficient. Also, if the flower buds are blocked by the top leaves, remove the leaves to ensure the buds get sunlight.
3. Suitable Temperature
Camellias are very sensitive to cold. If the temperature drops below 15 degrees Celsius, they will stop growing or grow very slowly. Above 15 degrees Celsius, they can grow and bloom normally. Therefore, maintaining a higher temperature is necessary for camellias to grow better and produce more flowers. Low temperatures can cause leaves and flower buds to fall, so be cautious.
4. Watering and Fertilizing
The principle of watering camellias is to water them thoroughly when the soil surface is dry, and keep the potting soil as loose and breathable as possible to prevent rotting roots and leaves. Generally, after camellias produce flower buds, the amount of water should be just right, as too much or too little water can cause the buds to dry up and fall off. You can observe the surface soil of camellias; when it turns white or has slight cracks, water immediately. Additionally, since camellias prefer acidity and dislike alkalinity, you can add 2 drops of salt-free edible vinegar or fermented fruit peel water when watering.
The best time to fertilize camellias is when the flower buds start to differentiate in early May. Generally, you can apply a phosphorus-potassium fertilizer every 15-20 days, for about 3 applications. Also, during the growth period of camellia flower buds, promptly supplement with potassium dihydrogen phosphate, which can be diluted in 1000 times water and applied once every two weeks until the camellia flower buds are fully open.
5. Thinning and Pruning
When camellia flower buds grow to the size of soybeans, thinning should be done promptly. Generally, strong branches can retain 2 flower buds, while thin branches can retain 1. When thinning, simply break off the flower buds or cut off half of the flower buds with pruning shears, and the remaining 1/2 will fall off by itself.
6. Ensure Ventilation
When growing camellias indoors, try to maintain good ventilation, as poor ventilation can cause leaf rot or leaf spots. If the ventilation is really poor, you can spray with mancozeb once or twice a month.
Camellias are relatively easy to care for. By paying attention to the above details, they grow quickly, becoming lush and flowering more each year. Whether growing camellias in pots or outdoors, it's important to follow the above care points.
The above content about how to care for camellias, as well as methods and precautions, is provided for green plant enthusiasts to refer to, and it is hoped that it can help solve your problems in green plant and flower management.
