What flowers are suitable for planting in Taizhou
Located on the coast of Zhejiang, Taizhou boasts a unique subtropical climate that makes it an ideal growing environment for a variety of flowering plants. With an annual average temperature of 18.5°C and abundant rainfall, it provides a natural greenhouse environment for over 80 ornamental plants. Understanding the local climate and plant growth patterns can make gardening efforts more effective.
Climate and soil characteristics of Taizhou
Obvious advantages of monsoon climate
The climate features no severe cold in winter (extreme low temperature ≥ -4°C) and frequent rain showers in summer, combined with over 1800 hours of annual sunshine, making it especially suitable for cultivating shade-tolerant and moisture-tolerant plants. The unique marine climate regulation keeps the day-night temperature difference stable at 8-10°C, effectively extending the growing period of plants.
Key points for soil improvement
Taizhou is dominated by acidic red soil, so it is recommended to add decomposed leaf soil (in a ratio of 1:3) before planting to improve drainage. For deep-rooted trees such as camphor and osmanthus, the soil layer should be deeply turned to over 60cm to ensure space for root development.
Recommendations for planting special flowers in Taizhou
Main varieties for courtyard planting
Osmanthus, as the city flower, is recommended to plant the Dan Gui variety (blooming from September to October), and the soil pH should be maintained between 5.5-6.5. When planting with the city tree camphor, it is suggested to keep a distance of more than 5 meters to avoid root competition. Woody flowers such as azalea and camellia should be planted in clusters to form a three-dimensional landscape.
Optimal categories for balcony planting
Shade-tolerant plants like虎皮兰 (Huepi Lan) and吊兰 (Diao Lan) adapt well to high-rise environments, and weekly twice spraying can maintain the luster of the leaves. Flowering plants like 蓝雪花 (Lan Xue Hua) and 小木槿 (Xiao Mu Jin) require 4 hours of direct sunlight daily, and should be fertilized with potassium dihydrogen phosphate (0.2% concentration) every half month.
Cultivation of special plants
Coastal areas can try planting salt-tolerant plants like柽柳 (Cheng Liu) and 海桐 (Hai Tong), using elevated planting beds (30cm) combined with pearl rock substrates (20% proportion). In mountainous areas, it is suitable to develop alpine azaleas, and attention should be paid to setting up sunshade nets (50% shading rate) to prevent strong sunlight in summer.
Essentials for maintaining the city tree and flower
Osmanthus fine management
Prune the overgrown branches promptly after flowering (retaining 3-4 buds), and apply organic fertilizer (10-15kg per plant) in March every year. Pay attention to the prevention and control of red spiders, and biological control can be carried out by hanging yellow sticky insect boards (1 board per 5 square meters).
Camphor cultivation techniques
Windbreaks need to be set up during the seedling stage, and drooping branches should be pruned annually on mature trees. For common camphor moth, it is recommended to spray Bacillus thuringiensis (500 times solution) for prevention from April to May. When transplanting, retain a soil ball diameter 8 times the size to ensure survival rate.
Taizhou's diverse microclimate provides endless possibilities for plant cultivation. From the fragrant osmanthus to the towering camphor trees, by utilizing regional climatic advantages and combining scientific maintenance methods, impressive landscape effects can be achieved whether it's courtyard landscaping or balcony greening. With the advancement of sponge city construction, native plants with strong adaptability and high ecological benefits will be more favored.
