The latest maintenance method of Pearl Plum Bonsai

Pearl plum, also known as Spiraea, belongs to the genus Spiraea of Rosaceae, deciduous shrubs, luxuriant branches, umbels, dense white flowers, like snow. The flowering period is from April to May, which is suitable for cluster planting, group planting and slice planting, and the beautiful appearance of family potted plants is more relaxing and pleasant.

Pearl plum originated in northern Asia, is a deciduous broad-leaved shrub plant, is a kind of plant that likes the sun. Because it has multiple resistance abilities such as shade tolerance, cold tolerance, drought resistance and moisture resistance, it is very simple and easy to use, so it is a kind of courtyard decoration plant suitable for novice breeding.

Pearl plum is named for its design and color like pearls. Its flowers, leaves are beautiful, the flowering period is very long, is a very popular ornamental tree species in the garden application, can be planted alone, row planting, cluster planting effect is very good. Pearl plum has strong germination and regeneration ability, wide cultivation range, lax soil requirements, and extensive management of water and fertilizer, temperature and light, which is suitable for greening and beautification cultivation in various places.

Pearl plum, like light and shade, wet and drought, fertile soil, warm and cold, can grow in slightly acidic or slightly alkaline soil with good drainage, but avoid waterlogging and strong tillering ability.

Basin soil should choose good permeability, strong drainage performance, more fertile loam. Organic fertilizer was applied at the end of autumn and early winter, and phosphorus and potassium fertilizer was applied before flowering. Usually appropriate amount of watering, keep the basin soil moist, do not be too wet for a long time, let alone waterlogging. Pot plants should be placed in direct sunlight as far as possible, winter low-temperature dormancy is its physiological needs, can not be put into the greenhouse, so as not to affect the growth and flowering of the next year, placed in the open air, leeward, sunny place or cover the basin soil to cover the winter. Prune every year after falling leaves to before sprouting in the second year, and cut off the weak ones in the diseased, dry and withered branches and overdense branches. Truncate too long branches, so that it maintains a good plant type, ventilation and light, in order to facilitate flowering.

Lighting:

Pearl plum prefers a warm, moist and sunny environment. Adult plants can also tolerate cold and semi-shade. Autumn cutting seedlings, to the following summer, happens to be the tender shoot and tender leaf growth period, the grower should according to the position of the seedling bed, pay attention to shelter shading to avoid strong direct sunlight, so that it can have scattered light. Flowering and fruit-hanging plants should be exposed to sunlight to make their photosynthesis exuberant and promote the exuberant growth of plants.

Temperature:

The most suitable temperature for the growth of Pearl Plum is 18 ℃ ~ 32 tons. If the temperature is suitable, the light is sufficient, coupled with reasonable water and fertilizer management, Pearl Plum will be able to enter the luxuriant growth period, with pearly buds glowing on the crown. Pearl plum is hardy, and it is not necessary to take any cold prevention measures in winter, so it can survive the winter in the open field.

Watering:

Pearl plum needs a lot of water and nutrients in the vegetative growth and reproductive growth period. Pearl plum like to be wet, the growing season, according to the local climate, the level of groundwater level, as well as soil moisture, appropriate watering. Especially after each fertilization, the water should be filled thoroughly to meet the water needs for the growth of pearl plum. In summer, we should pay attention to drainage and waterlogging prevention, and plants cultivated in the courtyard should dig ditches ahead of time and do a good job of drainage and waterlogging prevention. In case of summer drought, it is necessary to increase the frequency of irrigation and keep the soil moist. The amount of water should be reduced appropriately in autumn. Before entering the winter, we should also irrigate the overwintering water once, so that Pearl Plum can survive the winter safely in a humid environment.

Fertilization:

After the new buds germinate in spring, the mature organic liquid fertilizer can be applied every 20 to 30 days with a concentration of 1:4 or 1:6, and the water can be irrigated the next day to make the soil loose, moist and fertile, and promote the vegetative growth of Pearl Plum more exuberant. From April to May, Pearl Plum soon entered the flower bud differentiation stage, when fertilization should be applied with phosphorus and potassium-based fertilizer, once every 10-15 days. Fertilization can be stopped during flowering, and fertilization should continue after hanging fruit. After falling leaves in autumn, the plant should be trimmed once, and ditches should be dug around the plant, and solid fertilizer such as rotten barnyard manure should be applied. This fertilization is very critical, which can lay a good foundation for flowering and fruit hanging in the coming year.
