When do cherry blossoms bloom?
This article explains the blooming time of cherry blossoms and offers some green plant maintenance tips for managing the flowering period of cherry trees. Here is a detailed introduction.
Cherry blossoms, also known as cherries, are a favorite fruit for many people. They have beautiful flowers and nutritious fruits,被誉为 "a treasure among fruits." So, when do cherry blossoms bloom? How can we manage the flowering period of cherry trees? We will discuss these two questions.
Cherry blossoms typically bloom from March to April each year, with the specific time affected by climate, variety, and region. In southern China, where the climate is warm, the blooming time of cherry blossoms might be earlier; in northern China, the blooming time is relatively later.
To ensure the yield and quality of cherries, the management of the flowering period is crucial. Here are some key points for managing the flowering period of cherry trees:
Irrigation: Cherry trees require a significant amount of water during growth, especially during the flowering period, to keep the soil moist. However, excessive water can lead to oxygen deprivation in the roots, affecting the growth of cherry trees. Therefore, it is necessary to irrigate appropriately according to the weather and soil conditions, keeping the soil moisture at 60%-80%.
Fertilization: Cherry trees have high nutritional requirements during the flowering period. An appropriate amount of organic fertilizer and phosphorus-potassium fertilizer should be applied before the flowering period to ensure nutrition. However, excessive fertilization can lead to excessive growth of cherry trees, affecting the normal progress of the flowering period.
Disease and pest control: Cherry trees are susceptible to diseases and pests during the flowering period, such as grey mold and aphids. Disease and pest control should be carried out before and after the flowering period, using low-toxicity and low-residue agents and alternating their use to reduce resistance.
Pruning: Moderate pruning should be done on cherry trees before the flowering period to remove sick, weak, crossed, and dense branches, allowing for better ventilation and light penetration, which is beneficial for the growth and development during the flowering period.
Pinching: During the flowering period of cherry trees, new shoots grow rapidly, which can affect the nutrition. Therefore, pinching should be done at the right time to control the growth of new shoots and ensure nutritional needs during the flowering period.
Environmental control: The flowering period of cherry trees requires certain environmental conditions. It is important to maintain the greenhouse temperature between 15-25℃ and relative humidity between 60%-70%. In case of continuous cloudy days, ventilation and light penetration should be enhanced to reduce humidity and prevent diseases and pests.
Promoting flowering measures: To improve the quality of cherry blossom flowering and fruit setting rate, the following measures can be taken:
a. Spraying growth regulators: Such as paclobutrazol, chlormequat, etc., which can inhibit the vegetative growth of cherry trees, promote reproductive growth, and improve flowering quality and fruit setting rate.
b. Thinning flowers and fruits: During the flowering period of cherry trees, thinning should be done based on the tree's vitality and the amount of flowers, removing weak flowers and fruits to ensure fruit quality.
In summary, managing the flowering period of cherry trees is a key link to improving yield and quality. Through the above measures, we can effectively ensure the quality of cherry blossom flowering and fruit setting rate, laying the foundation for a good harvest. Of course, in actual production, management measures should be adjusted flexibly based on local climate, soil, and variety conditions for optimal results.
