Cultivation and Management of Cherry Blossom

Cherry blossoms are deciduous trees of the genus Prunus in Rosaceae. They bloom successively from March to May, with corymbals or racemes, often with 3-6 flowers, with white, light green, pink and red petals. The petals are single, semidouble and double, and some of them are more than 50 petals. The flowers are large and gorgeous, such as clouds and clouds.

Cherry blossoms are mainly planted on the ground, and the pot should be deeper and larger. Rotten leaf soil and vegetable garden topsoil can be used to cultivate soil, and a layer of broken charcoal or hard plastic foam blocks can be placed at the bottom of the pot to enhance air permeability and drainage anti-rot roots. Turn the basin and change the soil once in 2 ~ 3 years, transplant or turn the pot to change the soil, and the north should take the soil before sprouting in spring, after falling leaves in the south or before sprouting.

Cherry blossoms are positive flowers and trees, like sunny environment, so they should be planted in open gardens or courtyards with plenty of sunshine, and should not be shaded by high-rise buildings or tall trees. If the sunshine is insufficient, the branches will be less and the color will be light, and if there is too much shade, there will be no flowers. It is afraid of dry wind, grow poorly on the balcony of high-rise buildings, and can often spray water to branches and leaves or sprinkle water to the balcony floor to increase air humidity. It is hardy and can be planted from the north to the south, but some varieties are not resistant to heat and grow worse and have fewer flowers in the subtropics.

The propagation is mainly grafting. The seedlings of cherry, mountain cherry or single cherry blossom are used as rootstocks and grafted in late March or late August by bud grafting. Cuttings should use 1-or 2-year-old twigs growing near the trunk, cut horseshoe-shaped branches from near the trunk with a sharp knife before sprouting, cut them again, leave 2 or 3 buds to sprout new branches, and place them in semi-shaded places after insertion, often spray water to moisturize, but the soil should not be too wet, and then gradually move to the sunny place for maintenance when the new buds are 10 cm long, and then plant with soil in the following spring, the survival rate of cuttings with upper branches is low, especially the excellent varieties are difficult to survive. In addition, the seed plants sometimes germinated between the root plants of cherry blossoms, and the 1-and 2-year-old seeds were dug up in early spring and planted separately, with a survival rate of 100%.
