Culture methods and matters needing attention of potted camellias

Camellia, also known as Camellia, Camellia, etc., is a Camellia shrub or small tree plant, the flowering period is longer, it blooms from October to May of the following year, and the flowering period is usually from January to March. Here is an introduction to the cultivation methods and matters needing attention of camellia potted plants!

1. Selection of basin soil

According to the growth characteristics of camellia, we should choose slightly acidic, loose, fertile and well drained mixed soil as basin soil, especially pay attention to good drainage, do not use calcareous soil, the proportion of mixed soil is 6 parts of red soil, 3 parts of orchid mud (rotten leaf soil), 1 part of fine sandy soil, the basin size should be moderate, should not be too large or too small. In general, the ratio of pot to seedling is that a camellia with a height of 40~50cm and crown width of 20~25cm should be planted in a purple sand basin or tile basin with a diameter of 20cm, and so on.

Second, the time of potting.

The potting time of camellia is November in winter and February to March in early spring, when the buds are hypertrophic and the flowers are in full bloom, which is most suitable for potting. When the flowers are withering and the new roots are still sprouting, special attention should be paid not to hurt the roots if they are to be potted. Generally, they stop potting before and after the budding period, because at this time the new shoots are waiting for sprouting and the leaves are developing, which requires a lot of water. If the new roots are injured, it is easy to affect the growth and development of the year. High temperature and severe winter season also avoid pots, so as not to cause plant atrophy and death.

Third, the method of putting on the basin

First, put 3 or 4 pieces of broken tiles on the bottom hole of the selected flowerpot, then fill some coarse soil, plant the seedlings in the basin, fill the roots with fine soil, and then slowly fill the four sides of the basin with larger grains of potted soil, gently shake the basin, press it by hand, so that the potted soil is close to the root, and the big pot can be gently compacted down with bamboo sticks, and be careful not to hurt its root. The potted soil should account for 412% of the pot height for watering.

Fourth, watering method

The newly potted seedlings remain moist, and can be watered like other potted seedlings after 2 months. the watering times should depend on the climatic conditions, and the principle of keeping the soil moist is to keep the soil moist. It is generally possible to water more in spring to meet the needs of sprouting and shooting. summer watering should be carried out in the morning and evening, water should be prevented in the Meiyu period, timely watering in autumn drought, and watering in winter should be carried out at noon to prevent basin soil from freezing, soil drying and freezing even more intense.

5. Fertilization methods

Camellia does not like fertilizer very much, and it is not necessary to apply too much fertilizer. Generally, mixed fertilizers (human feces and urine, cake manure, barnyard manure, phosphate fertilizer) are generally used for 2 to 4 times before flowering and 4 ~ 5 months after flowering. Phosphate fertilizer is the main fertilizer and nitrogen fertilizer is used as a secondary fertilizer to prevent branches from growing and flowers decreasing. All kinds of fertilizers must be used after full ripening, but rapeseed cake and fish meal can be removed directly on the soil surface and covered with a thin layer of soil without decay. Allow it to slowly rot and infiltrate into the soil for root absorption, the amount of fertilizer should be mastered that strong seedlings should be applied more, weak seedlings should be applied little or no, and for seedlings whose growth is too weak, the effect is also very good by replacing pot soil instead of fertilization.

VI. Shelter from the cold

Camellia likes warm and humid climate, too cold and heat is not conducive to growth and development, spring and Meiyu period should give potted camellia sufficient sunshine, otherwise the branch development is weak, it is easy to cause bituminous disease and scale insects, or epiphytic moss, resulting in withered branches, senescence or death, timely shade and cooling in summer and autumn, and the temperature drops below zero in winter, it will cause flower buds to fall off or stamens frozen. It affects the flowering quality, so the indoor overwintering temperature of potted seedlings should be kept at about 3-4 ℃. If the temperature is higher than 16 ℃, it will promote early germination, and seriously cause deciduous leaves and buds.

VII. Disease prevention and control

The main pests of camellia are stem borer and shell worm, and the main diseases are anthracnose on leaves, black coal disease and mossy parasitism on branches.

VIII. Points for attention

Camellia is not suitable for intensity pruning, its flowers, leaves and buds take a long time to develop, and the crown is formed evenly, basically without special pruning, as long as the disease and insect branches, overdense branches, weak branches and truncated long branches are cut off. Camellia is a multi-flowered tree species, especially on weakly growing plants, if the buds are dense, it will consume too much nutrients, which is disadvantageous to the plant growth, so picking buds is an important part of cultivation and management. It is appropriate to leave 1 bud and 2 buds on each branch, leaving only 3 buds at most, and keep a certain distance. The buds thinned can be used for medicinal purposes. The flowering period of camellia is longer, and the whole flowering period is as long as half a year, so picking close to withered flowers in time is of great benefit to reduce nutrient consumption and enhance tree potential.

The above is the introduction of Tuliu.com on the cultivation methods and matters needing attention of potted camellias. Friends who have planted potted camellias at home can refer to them. The flowering period of camellias is as long as half a year, and it is worth planting flowers and plants at home to watch.
