What are the landscape trees
In courtyard design and urban greening, landscape trees are not only the finishing touch in spatial aesthetics but also an important carrier of ecological balance. The reasonable selection of landscape tree species should consider both seasonal ornamental value and growth characteristics, as well as regional adaptability. This article will systematically analyze the unique charm and matching skills of five classic landscape tree species.
Analysis of the characteristics of the five classic landscape trees
Ginkgo Tree: A living fossil intertwined with time and space
The ginkgo tree, as a relic plant left after the Quaternary glacial movement, has both ornamental leaf and flower characteristics. The fan-shaped leaves are light green in spring, turn deep green in summer, and turn golden yellow in autumn, forming a unique seasonal landscape. It is recommended to pair it with evergreen shrubs as a background to highlight its seasonal change characteristics. Note that the fruit of the female tree is prone to decay and produce an unpleasant odor, so male grafted seedlings should be chosen for public areas.
Osmanthus Tree: An expert in creating aromatic landscapes
The osmanthus tree, with its evergreen characteristic and Mid-Autumn Festival blooming period, has become a choice that excels in both olfactory and visual aspects. Varieties such as golden osmanthus, red osmanthus, and four-season osmanthus can be planted in combination to extend the viewing period. Planting tips: Plant 5-8 meters away from building doors and windows to enjoy the fragrance while avoiding root damage to the foundation. Regular pruning to maintain an umbrella-shaped canopy can be combined with landscape stones to create a Zen space.
Maple Tree: The protagonist of the autumn visual feast
Variegated maple and Chinese maple varieties demonstrate the rhythm of the seasons through leaf color changes. Acidic soil can enhance the red leaf effect, and it is recommended to interplant with acid-loving plants such as azaleas and gardenias. Planting maple trees around water features can create a double landscape dimension with reflections and red leaves. Be aware of preventing longicorn beetle pests and regularly check for holes in the trunk.
Banyan Tree: Master of tropical landscape creation
What are the landscape trees
The aerial root characteristic makes it a core element of the rainforest landscape, and the effect of a single tree forming a forest requires maintaining an air humidity of over 70%. Shaping and pruning focus: Retain 3-5 main aerial roots to guide the growth direction, and pair with ferns to create a three-dimensional ecosystem. It is recommended to use local varieties with strong wind resistance for municipal projects, and to control the root range in courtyard planting.
重阳木: Multipurpose ecological protector
The umbrella-shaped canopy provides excellent shade, and the spring flowers and autumn leaves create a double scenic characteristic. It has strong resistance to pollution and is suitable for planting in road median strips. Planting suggestions: Plant alternately with crape myrtle to form an upper and lower flowering landscape. Pay attention to the prevention and control of the锦斑蛾 caterpillar, and set up traps in advance each May.
The selection of landscape trees needs to consider the spatial scale, soil conditions, and maintenance costs. It is recommended to adopt a three-layer matching mode of "trees + shrubs + ground cover," such as a combination of ginkgo + red maple + Korean Fir, which can ensure all-season viewing and form a stable ecosystem. Regular professional pruning and pest and disease control are necessary to showcase the best ornamental effect of landscape trees.
