When Do Cherry Blossoms Bloom in 2020? A Detailed Guide to Cultivation Techniques

Cherry blossoms have elegant, delicate colors and are extremely beautiful flowers. At present, they are cultivated in many places in our country, and in recent years the number of people admiring cherry blossoms has gradually increased. So, in which month do cherry blossoms bloom in 2020? Cultivation techniques attached!

1. When do cherry blossoms bloom in 2020?

The blooming time of cherry blossoms is affected by factors such as temperature and rainfall. It is expected that in 2010 most cherry blossoms in our country will bloom in mid-to-late March. It takes about 7 days for a single cherry blossom to go from opening to withering, and about 16 days for an entire cherry tree to go from flowering to full withering, forming the characteristic of cherry blossoms blooming and falling at the same time. Cherry blossoms bloom in March. For example, at Wuhan University, a famous cherry blossom viewing spot in our country, the cherry blossoms at Wuhan University bloom most abundantly from mid-to-late March each year, and the flowering period is relatively short, only about 13-20 days.

1. Planting

Before planting, level the ground. Dig a pit 0.8 m in diameter and 0.6 m deep. First fill the pit with 10 cm of organic fertilizer, then place the seedling into the pit and spread its roots out in all directions. After filling the pit with soil around the cherry blossom, lift the seedling slightly so the roots spread deeply, then firm the soil. The planting depth should be about 5 cm above the upper layer of the seedling roots. After planting, water thoroughly and irrigate fully, and support it with a stick to prevent it from being blown over by strong winds.

When planting, apply 15 kg-25 kg of decomposed compost per pit. In July, apply 1 kg-2 kg of ammonium sulfate per plant. After flowering and before budding in early spring, prune out dead branches, diseased and weak branches, and leggy branches. Try to avoid pruning thick branches so as to keep the crown full and rounded.

2. Watering

After planting, seedlings are prone to drought damage. In addition to thorough watering at planting, water once every 8-10 days thereafter, keeping the soil moist but without standing water. After watering, loosen the soil promptly. It is best to cover the ground surface with a thin layer of grass to reduce water evaporation. Within 2-3 years after planting, to prevent the trunk from drying out, it can be wrapped with rice straw. However, after 2 to 3 years, once the seedlings grow new roots and their adaptability to the environment gradually increases, there is no need to wrap them with straw anymore.

3. Fertilizing

Cherry blossoms are fertilized twice a year, and acidic fertilizers are preferable. One is winter fertilizer, applied in winter or early spring using organic fertilizers such as bean cake, chicken manure, and decomposed fertilizer; the other is after the flowers fall, applying quick-acting fertilizers such as ammonium sulfate, ferrous sulfate, and superphosphate. Generally, for fertilizing large cherry trees, the hole application method can be used, that is, at the edge of the vertical projection line of the tree crown, dig a ring-shaped trench about 10 cm deep and apply the fertilizer into it. This method is both simple and conducive to root absorption. As the tree grows, the diameter and depth of the fertilizing ring trench should also increase accordingly. The cherry blossom root system is shallow and requires good drainage and aeration. Therefore, around the tree, especially within the root distribution range, never let people, livestock, or vehicles compact the soil. Trampling by pedestrians will weaken the tree, shorten its lifespan, and even cause root rot and death.

4. Pruning

Pruning mainly involves cutting off withered branches, leggy branches, overlapping branches, and diseased and pest-infested branches. In addition, when many branches grow from the trunk of a large cherry tree, several vigorous branches should be retained and the rest cut off entirely from the base to improve ventilation and light penetration. After pruning, disinfect the wounds on the branches promptly with medication to prevent pathogens from invading after rain and causing rot. After long exposure to the sun, the bark of cherry blossoms is prone to aging and damage, causing rot. It should be removed promptly and disinfected. After that, wrap the rotted area with leaf mold and charcoal powder to help it recover normal physiological function.

5. Pest and disease control

Cherry blossoms mainly need prevention against gummosis and root nodule disease, as well as pests such as aphids, red spider mites, and scale insects. Gummosis is caused by moths drilling into the trunk to lay eggs. You can dig out the eggs with a sharp knife, while also improving the soil and strengthening water and fertilizer management. Root nodule disease causes the roots of affected trees to be unable to grow normally. No matter how you fertilize, the tree still will not be vigorous. The tumors should be removed promptly, the soil disinfected, and the soil improved using leaf mold, charcoal powder, and microorganisms.

Because the cherry blossom flowering period is relatively short, friends who want to admire cherry blossoms in 2020 can start paying attention to the blooming situation of cherry blossoms in early March.
