When does the latest flower bloom?

Camellia, also known as Camellia, is a camellia plant of the family Theaceae. it likes a warm and humid environment and blossoms for a long time from October to May of the following year. The blooming period is usually from January to March. It is native to eastern China and is one of the most valuable flowers and trees in the world. Let's take a look at when the camellia blossoms.

When do the camellias bloom?

Camellia blossoms continuously from the end of September to the beginning of May because of different varieties. It is full of vitality in late autumn, cold winter and early spring. Camellia has two shoots a year, the first is spring shoots, which begins from March to April and summer shoots from July to September. The flowering period of camellia is long, most varieties are 1-2 months, the single florescence is 7-15 days, and the flowering period is 2-3 months.

Maintenance of Camellia after flowering

Camellia has colorful flowers, beautiful and diverse patterns, elegant and polymorphic flowers and fragrant smell. the maintenance and management after flowering period should pay attention to the following points:

1. Pruning in time: after the full flowering period, the remaining residual flowers should be removed, and at the same time, the overdense overlapping branches, cross branches and dry branches should be cut off to prevent empty consumption of tree nutrients on the one hand, and enhance the ventilation and ventilation ability of the plant on the other hand. Prevent the occurrence of diseases and insect pests (such as shell insects, black spot) and promote the healthy growth of plants.

2. Timely fertilization: Camellia consumes a lot of nutrients from pregnant buds to blossoms. In order to restore the tree potential quickly, it must be supplemented by fertilization. Apply thin liquid fertilizer every other week or so after flowering. Liquid fertilizer can be made with bean cake, hoof horn, fish bone meal and black alum combined with sealed bubble. After ripening, the upper fermentation liquid can be diluted with water. Do not irrigate with thick fertilizer and raw fertilizer to avoid rotting roots. At the same time, 0.2% potassium dihydrogen phosphate can also be used for extra-root topdressing, spraying once every ten days for 5 times in order to promote the stout spring shoots and improve the ability of pregnant buds.

3. Appropriate watering: around the middle of April, the spring shoots of camellias begin to grow, but at this time the climate is dry and the air humidity is small, so they should be properly watered and spray foliar water once or twice a day to increase local air humidity to facilitate plant growth.

4. Change the pot in time: the plant that should change the pot should be changed immediately after flowering. When changing the basin, it is best to use the delayed fertilizer such as hoof horn and hair as the base fertilizer, pour water once after changing the basin, put it in a moist and cool place, and carry out normal management after 20 days.

Culture methods of Camellia

1. Selection of basin soil and basin: according to the growth characteristics of camellia, the mixed soil with slightly acidic, loose, fertile and good drainage should be selected as basin soil. Special attention should be paid to good drainage and do not use calcareous soil. The proportion of mixed soil is 6 parts of red soil, 3 parts of orchid mud (rotten leaf soil) and 1-2 parts of fine sandy soil. The size of the basin should be moderate, not too big or too small. The ratio of general basin to seedling is: a camellia with a height of 40-50 cm and a crown of 20-25 cm should be planted in a purple sand basin or tile basin with a caliber of about 20 cm. Other sizes, and so on.

2. The potting time: the potting time is November in winter and February-March in early spring. At this time, the buds are enlarged and the flowers are in full bloom, which is the most suitable for pots. When the flowers are withering and the new roots are still sprouting, if you want to put them on the pot, you must pay special attention not to hurt the roots. Generally stop potting before and after the sprouting period, because at this time the new shoots are waiting to be sent and the leaves are developed, which requires a lot of water, such as pots, new roots are injured, which can easily 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.

3, pot method: first put 3-4 pieces of broken tiles on the bottom hole of the flowerpot, then fill part of the coarse soil, plant the seedlings in the basin, fill the root with fine soil, and then slowly put the larger grain of basin soil all around the basin, gently shake the basin and press it by hand to make the basin soil and root close. Large pots can be gently compacted down with bamboo sticks, and be careful not to hurt their roots. The basin soil should account for 4% of the basin height and 5% for watering.

4. Watering method: the seedlings newly put on the basin should be watered for the first time until the bottom of the basin is permeable. The seedlings newly put on the pot should be kept moist and can be watered like other pot seedlings after 2 months. The frequency of watering depends on the climate, based on the principle of keeping the soil moist. Generally, it can be watered 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 the basin soil from freezing, and the soil is dry and frozen more intensely.

5. Fertilization method: Camellia does not like fertilizer very much, and there is no need to apply too much fertilizer, generally 10-11 before flowering, 4-5 months after anthesis, fertilizing 2-4 times. General use of mixed fertilizers (human feces and urine, cake fertilizer, barnyard manure, phosphate fertilizer), it is best to give priority to phosphate fertilizer, nitrogen fertilizer as a deputy, in order to prevent branches from growing and flowers decreasing. All kinds of fertilizers must be fully mature and used, but rapeseed cakes and fish meal can be removed directly on the soil surface without decay, covered with a thin layer of soil, and allowed to slowly rot and seep into the soil for root absorption. The amount of fertilizer application should be mastered that the strong seedlings should be applied more, and the weak seedlings should be applied less or not. for the seedlings whose growth is too weak, replace the pot soil instead of fertilization, the effect is also very good.

6, shade and cold protection methods: Camellia likes warm and humid climate, too cold and heat are not conducive to growth and development. The potted camellias should be given plenty of sunshine in spring and Meiyu period, otherwise the branches are weak, which can easily cause bituminous disease and shell insects, or epiphytic moss, resulting in withered branches, senescence or death. The high temperature season in summer and autumn should be sheltered and cooled in time. When the temperature drops below zero in winter, it will cause buds to fall off or stamens to be frozen, affecting the quality of flowering. Therefore, the indoor overwintering temperature of potted seedlings should be kept at about 3-4 ℃. If the temperature exceeds 16 ℃, it will promote early germination and serious defoliation and buds.

7. Pest control: the main pests of camellia are stem borer and shell insect. The main diseases are anthracnose on the leaf, black coal and mossy parasitism on the branches. The damaged branches should be cut off and sprayed in time.
