How to plant four-season camellias
This article provides you with experience on how to plant four-season camellias and the cultivation methods for maintaining green plants, please see the detailed introduction below.
Four-season rhododendron camellias are a variety of camellias that can bloom throughout the year, but they require a temperature of 15 degrees Celsius or higher for maintenance, as they are flowers from the south. Therefore, low temperatures are certainly not suitable. If you are growing them in the north, never let them overwinter outdoors. They must be placed in a suitable indoor temperature condition to grow and bloom normally. The leaves of rhododendron camellias resemble those of rhododendrons, and they have a very strong blooming ability. Now commonly found in the market and also popular in homes, how should we care for the rhododendron camellias we purchase to ensure they bloom throughout the year without any issues?
Four-season rhododendron camellias prefer plenty of light. Compared to other camellias, they have stricter requirements for sunlight. During maintenance, they can be exposed to half a day of sunlight, but avoid midday direct exposure. They can be exposed to sunlight before 11 am and after 1 or 2 pm in the afternoon. Sufficient sunlight ensures their leaves do not get sunburned, maintaining deep leaf color and preventing excessive growth without blooming.
Fertilization is also crucial, as they bloom continuously throughout the year. After new lateral buds grow to a certain height and gradually age, flower buds will emerge from the top, which is a characteristic of their blooming and the reason why they bloom throughout the year. Therefore, when choosing fertilizer, do not use pure phosphorus and potassium fertilizers, as they can lead to blooming only one or two times, and without nutrient supply later, the branches will not grow, and flower buds will not develop. Choose fertilizers high in phosphorus and potassium elements, and also containing other elements, and provide them 2 to 3 times a month during the growing season without affecting the growth of lateral buds, ensuring continuous blooming.
Watering frequency is also important. If indoor ventilation is poor, water the plant when the potting soil is half-dry or almost dry. Do not water too frequently, as it may cause waterlogging and root rot. The prerequisite for maintenance is that the soil must be breathable and permeable, which is essential for any plant. I usually use a mix of nutrient-rich soil and river sand in a 1:1 ratio for growing them, which is breathable, permeable, and nutrient-rich. Occasionally, I add a bit of pine needle soil to the soil to increase its acidity, as they are acid-loving flowers. If you do not add pine needles to the soil, you should water the plant with a solution of ferrous sulfate once a month to prevent the soil from becoming alkaline, which can lead to yellowing leaves and stunted growth.
Rhododendron camellias are very easy to grow, and they can bloom and grow throughout the year as long as the temperature is maintained between 15 and 25 degrees Celsius. However, proper ventilation, adequate sunlight, and breathable, permeable soil are essential. Choose fertilizers high in phosphorus and potassium elements. After blooming,剪掉残花 (remove the withered flowers) promptly, and prune the branches if they are too long. This will promote the rapid growth of lateral buds, which, after aging for some time, will produce flower buds at the top and bloom. This will allow them to bloom throughout the year, grow continuously, and not encounter any problems.
