In spring, walking on the road, we often see endless fields of crabapple flowers. The crabapple flower, also known as the cold plum blossom, is acclaimed as the "fairy flower" for its elegant and noble temperament. But do we know when crabapple flowers bloom? This article will explore the reasons for the flowering time of crabapple flowers from aspects such as climate, light, and soil.
I. Climate
1.1 Spring Temperature Rise
The rise in temperature in spring is one of the prerequisites for crabapple flowers to bloom. When the temperature rises to 5-10°C, the crabapple flowers begin to sprout.
1.2 Suitable Temperature
Crabapple flowers prefer a warm environment; at a temperature of around 20°C, they will produce more gorgeous blossoms.
1.3 The Effect of Temperature Changes on Crabapple Flowers
If the temperature fluctuates too much, such as high and low temperatures within a single day, the crabapple flowers can easily be damaged, leading to a shorter flowering period.
II. Light
2.1 Suitable Light Duration
Crabapple flowers prefer a well-lit environment. A sunny spring is the best season for crabapple flowers to bloom. A daily light duration of around 8-10 hours is most suitable.
