What Trees are Suitable for Southern Courtyards
In the warm and humid southern climate, courtyard greening should not only consider the adaptability of plants but also pay attention to their ornamental and functional aspects. Choosing tree species that match the regional characteristics can not only create a courtyard landscape with scenery all year round but also convey the host's aesthetic taste through plants. The following four classic tree species have both ecological value and cultural connotation, making them ideal choices for creating a poetic dwelling.
Plum Tree: The Noble Gentleman in the Courtyard with Unyielding Spirit
Ecological Adaptability Analysis
Plum trees are native to the south of the Yangtze River, and their well-developed root systems can effectively adapt to the rainy climate of the south. Low temperatures below 5℃ in winter can promote the differentiation of flower buds, and the blooming period coincides with the less rainy months of January to March, avoiding the risk of diseases during the southern plum rain season.
Landscape Configuration Techniques
It is recommended to use the diagonal planting method, combined with Taihu stones and white sand to create a dried landscape effect. In early spring, planting February兰花 can form a color contrast, and choosing narrow-leaved罗汉松 as the evergreen background tree adds elegance.
Osmanthus Tree: The Fragrant Star of Autumn
Water Management Tips
Young trees need to maintain soil moisture at 60%-70%, and drip irrigation should be used during the flowering period. The amount of water can be calculated using the tree crown projection method: projection area (㎡) × 3 liters = daily water requirement. After heavy rain, it is necessary to clear the drainage ditches promptly.
Plant Variety Selection Guide
Dan Gui is suitable for color viewing but has a mild fragrance, while Si Ji Gui has a long flowering period but weak cold resistance. It is recommended to plant Jin Gui and Yin Gui mixedly, which can extend the flowering period (September to November) and create a gradient change in fragrance.
Orange Tree: A Practical Choice for Auspiciousness
Anti-Freezing Maintenance Secrets
Use the "triple insulation method": in November, apply white paint to the trunk to reflect sunlight, heap 30cm of soil at the base, and cover the tree canopy with non-woven fabric. Spraying phosphorus and potassium solution every month during the fruiting period can increase the sugar content of the fruit by 2-3 percentage points.
Cultural Scene Creation
Hang red wish notes on the branches before the Spring Festival, combined with elements like stone mills and bamboo fences, to recreate the classical image of "orange yellow and green". It is recommended to plant dwarf varieties such as sand sugar oranges, which are convenient for children to participate in the picking experience.
Cherry Blossom Tree: A Romantic and Beautiful Visual Feast
Flowering Regulation Techniques
Temperature intervention can achieve staggered blooming: moving into a 5℃ greenhouse 30 days in advance in winter can promote flowering, while cold storage treatment can delay flowering. It is recommended to plant southern suitable varieties such as eight-petal cherry and Kizami cherry, which have a flowering period of 20-25 days.
Light and Shadow Design Techniques
Laying a mirror-like water feature in the tree crown projection area can create a visual wonder of "double cherry blossoms". Using 2700K warm light from the bottom up at night, the light transmission rate of the petals reaches 75%, creating a dreamy night effect.
The combination of select tree species and scientific maintenance can achieve the dual sublimation of function and aesthetics in southern courtyards. The character of plum blossoms, the fragrance of osmanthus flowers, the auspiciousness of orange trees, and the brilliant cherry blossoms together construct a rich and layered three-dimensional landscape. It is recommended to use the "3+1" planting mode (3 main landscape trees + 1 seasonal supplementary tree), combined with an intelligent irrigation system, to create a modern courtyard with low maintenance and high aesthetics.
