When Does海棠 Bloom
As the plant business card of a tropical coastal city, the blooming season of Sanya's海棠 always attracts the collective attention of tourists and plant enthusiasts. With the catalysis of the coconut breeze and sea rhyme, what kind of spatial and temporal variations will these beautiful flowers perform?
Association Between Sanya's Climate andBlooming Period
The unique geographical coordinate of 18 degrees north latitude allows Sanya's海棠 to enter the full bloom stage 1-2 months earlier than in the north. Measured data shows that when the north is still in the cold spring of March, Sanya's海棠 is already unfolding its flower buds in a microclimate with an average daily temperature of 22-26°C and humidity of 75%. This climatic advantage makes Sanya the earliest region in China to admire海棠.
Flowering Time Axis of Varieties
Monitoring by the Sanya Botanical Garden shows: Weeping海棠 takes the lead, showing initial buds at the end of February;贴梗海棠 takes over and enters the full bloom period in mid-March; and西府海棠 reaches its peak for viewing around Qingming Festival. With artificial control, Four Seasons海棠 can achieve annual cyclic blooming, becoming a permanent guest in hotel landscapes.
Extended Blooming Care Plan
Professional horticulturists recommend using the "3 Controls and 1 Supplement" method: control the temperature to maintain a day-night temperature difference of no more than 8°C, control water by implementing a red-line management of 60% substrate moisture, and control fertilizer by using slow-release phosphorus-potassium fertilizer. By adjusting the light intensity with a shading net, the single flower blooming period can be extended to 12-15 days.
From Yalong Bay to Tianya Haijiao, Sanya's海棠 is writing a unique chronology of tropical flowers with its blooming rhythm of intertwined time and space. Mastering these growth codes allows one to encounter the beauty of different海棠 in all seasons on the coconut island.
