Camellia varieties are abundant: master their characteristics and care methods for fuller blooms

Camellia is an evergreen shrub or small tree of the genus Camellia in the family Theaceae, also known as the camellia flower, and is one of China's traditional famous flowers. Its leaves are leathery and glossy, staying green all year round, and its flowers are large and showy, with colors covering red, pink, white and many others. Its blooming period is mostly concentrated in winter and spring, precisely filling the ornamental gap of the flower-sparse season.

The horticultural varieties of the genus Camellia are very rich. According to the arrangement of petals, they can be roughly divided into single, semi-double and double groups, and the flower forms include trumpet-shaped, lotus-shaped, peony-shaped and many other shapes. Common cultivated groups include the East China camellia, the Yunnan camellia and the golden camellia with golden-yellow flowers, among others. Different varieties differ in cold hardiness, plant form and flowering habits, so local climate conditions can be taken into account when choosing.

In caring for camellias, soil is key; a loose, fertile, well-drained, slightly acidic sandy loam is best. Daily watering should follow the principle of watering when dry and letting it dry out between waterings, avoiding water accumulation in the pot that causes root rot. During the growing season, fertilizer can be applied lightly and frequently, mainly matured organic fertilizer or acidic fertilizer. The plant likes a semi-shaded environment, so appropriate shading is needed in summer, and in northern regions it should be moved indoors in winter to keep warm. After flowering, promptly cut off spent flowers and dead or weak branches, which helps blooming the following year.

Camellias are suitable both for planting in the ground in courtyards and for growing in pots placed on balconies and in living rooms, making them a much-loved ornamental flower. In daily care, if the leaves turn yellow, it is mostly related to alkaline soil, iron deficiency or improper watering; bud drop is often caused by sudden temperature changes and dry air, so the environment should be kept stable and management adjusted promptly.
