Points to Consider for Potted Camellia
Here are some introductions on the precautions for potted camellias, which will be shared with everyone. Next, the editor will introduce these points.
1. Pay attention to the suitable temperature.
Camellias prefer warmth, with an optimal growth temperature of 18-25°C. The spring shoots usually start to germinate in late March to early April, sprout in April, form terminal buds in mid to late May, and gradually differentiate into leaf buds or flower buds. The summer shoots start to germinate in late July and stop growing in early September. Camellias can tolerate low temperatures, but sudden drops to below 0°C combined with dry northwest winds can cause frostbite and withering of tender branches and flower buds.
2. Pay attention to moderate sunlight.
Camellias enjoy sunlight but are sensitive to strong direct sunlight. They should be exposed to full sunlight in spring and late autumn to promote bud differentiation and ensure strong flower buds. When sunlight is strong, avoid direct exposure to prevent leaf damage or withering of small plants.
3. Pay attention to moderate watering.
Camellias enjoy moisture and need sufficient water. Water once a day in spring and autumn, twice a day in summer (morning and evening), and spray water around the pot 1-2 times. Let tap water sit for 1-2 days before watering, and often water with a 0.5%-1% ferrous sulfate solution, or spray the leaves with a 5%-8% vinegar solution. Keep the soil moist but avoid waterlogging.
4. Pay attention to nutrient supply.
Camellias require a lot of nutrients due to their numerous leaves and long blooming period. When repotting, apply decomposed cake fertilizer or dried chicken and duck manure as a base fertilizer at the bottom of the pot and mix it with the soil, making sure not to let the fertilizer come into direct contact with the roots to prevent root damage. Apart from the coldest and hottest times of winter and summer, apply decomposed cake fertilizer water 1-2 times a month, preferably applying the liquid fertilizer into the soil to avoid odors that attract fly maggots. Alternatively, apply decomposed cake fertilizer powder around the pot and mix it with the soil, allowing the plant to absorb it slowly, or use special fertilizer for flowering plants. Apply less fertilizer in summer and winter, and spray 1-2 times a month with a 0.2%-0.3% phosphorus acid solution and 1%-2% plant growth hormone. Apply thin and frequent fertilization, preferring dilute over concentrated, and avoid applying raw fertilizer.
5. Pay attention to planting in acidic soil, as well as moderate ventilation and the prevention and control of diseases and pests.
