What flowers are suitable for Liuzhou
In Liuzhou, where the red flowers of the Chinese redbud and the green shade of ancient banyan trees intertwine, it is particularly important to choose plants that adapt to the local climate. As a typical subtropical monsoon climate city, Liuzhou's unique humid and hot summers and dry and cold winters create a special environment for plant growth. Mastering the regional planting rules can not only create a colorful courtyard but also deeply feel the ecological pulse of the city.
Flower choices under subtropical climate
Adaptability to high temperature and humidity
The climate characteristics with an average annual precipitation of 1300mm and a frost-free period of up to 330 days make species such as bougainvillea and dragon blood tree, which are tolerant to humidity and heat, become preferred choices. These plants can maintain good drainage during the rainy season and continue to bloom even at high temperatures of 35°C.
Winter cold tolerance control
It is crucial to choose varieties that can withstand short-term low temperatures of -2°C. Plants such as hibiscus and camellia, which are not only ornamental but also can survive the winter in Liuzhou, have a critical low-temperature tolerance that fits the local climate characteristics.
Characteristics of plant planting practice
Tree layer configuration scheme
Large flower crape myrtle and toon tree are combined to form an ecological barrier, with a crown span of 6-8 meters, which can effectively regulate the microclimate of the courtyard. It is recommended to maintain a planting spacing of 5-7 meters to ensure that the roots can fully extend.
Implementation of vertical greening
Vertical greening is carried out using plants like Chinese trumpet creeper and ivy, with wall coverage reaching over 90%. It is necessary to set a planting trough 30 cm deep and use a drip irrigation system to maintain moisture.
Cultural connotation of city flower and city tree
Key points for planting Chinese redbud
As a symbol of Liuzhou, Chinese redbud prefers acidic red soil (pH 5.5-6.5), and is fertilized three times a year (once in spring, summer, and autumn), with attention to the prevention and control of scale insects. The flowering period can be extended to 120 days through water control.
Traditional maintenance of ancient banyan trees
The maintenance of thousand-year-old small-leaf banyan trees should follow the principle of 'three thinning and one supplementing': thinning dead branches, thinning dense branches, loosening compacted soil layers, and supplementing organic fertilizers. Air root guidance technology can increase the crown expansion rate by 40%.
From the flowering management of Chinese redbud to the cultivation of air roots of small-leaf banyan trees, the maintenance of characteristic plants in Liuzhou is both a technique and a cultural heritage. Choosing suitable species and scientific maintenance can make the courtyard flow in different colors throughout the four seasons, experiencing the ecological beauty of harmonious coexistence between humans and plants.
