Production and maintenance of spring bonsai

Yingchun has strong adaptability, like light, cold tolerance, drought tolerance, alkali tolerance, fear of waterlogging, lax requirements on the soil, can grow in slightly acidic, neutral and slightly alkaline soil, but grows best in loose and fertile sandy soil. Planting is usually carried out after flower withering or in mid-September. If you want to raise the root, you can raise the root appropriately when planting, but don't raise it too high at once, otherwise it will be harmful to the growth. Because the primrose is yellow, it is appropriate to choose the pot of light blue, purple and black when planting, so that the color of the pot and the flowers are in harmony. If cultivated properly, it will be full of yellow flowers in spring, green leaves in summer and autumn, green vines whirling in winter, and the four seasons are full of spring.

Maintenance and management

(1) venue. Yingchun, which has just been planted or changed, should be watered thoroughly, put it in a shaded place for about 10 days, and then put it in a semi-overcast and semi-sunny place; maintain it for a week, and then place it in a sunny, well-ventilated and humid place for maintenance. In winter, the south can safely survive the winter by burying the pot to welcome spring in the leeward and sunny soil, while in the north, it should be moved to a low temperature (about 5C) indoor in the early winter. If you want to make Yingchun blossom ahead of time, you can timely move it into the sunny room at medium temperature or high temperature. If you put it in the sunny place of about 13 ℃, spray clear water to the branches and leaves once or twice a day, it will blossom in about 20 days; if it is placed in the sunny place of about 20 ℃, it can blossom in about lo days. After flowering, keep the room temperature at about 8 ℃, and be careful not to let the wind blow directly to it, which can prolong the flowering period. After blooming, the higher the room temperature, the faster the flowers wither.

(2) watering. Welcome spring like to be moist, especially in the hot summer, in addition to watering once every morning, it should also be properly watered in the afternoon. In order to maintain the humidity of the small environment, water should be sprayed to the ground frequently. Yingchun is afraid of stagnant water in the basin. During the rainy season, when it rains continuously, the basin should be put down or moved to a place free from rain. Low temperature in winter, less water evaporation, should be less watering.

(3) fertilization. When planting to welcome the spring, you should put a few pieces of animal hooves at the bottom of the bowl as base fertilizer. During the spring growing period, mature and thin liquid fertilizer should be applied once or twice a month. Spring flower bud differentiation period is from July to August, so liquid fertilizer with more phosphorus should be applied to facilitate the formation of flower buds. Such as in the early stage of flowering, the application of a rotten thin organic liquid fertilizer can make the flower color bright and prolong the flowering period.

(4) plastic surgery. Primrose germination is strong, in the growth period to often pick the heart, cut or cut some branches in order to maintain the shape of the tree. After the flower withered, the branches should be cut short, generally leaving only 2-3 buds, the main branch can leave a few more buds, after the new branches are born, if properly maintained, the buds will grow.

(5) prevent diseases and insect pests. There are few diseases and insect pests in Yingchun, and red spiders occur occasionally, which should be eliminated in time.
