What flowers are suitable for cultivation in Xinyang

Located in the transition zone of the north and south climates, Xinyang's unique geographical location has created a rich diversity of plants. As a typical monsoon climate zone, the distinct temperature and humidity changes throughout the year provide excellent conditions for the growth of various flowers, and have also nurtured representative plants with regional characteristics.

Analysis of Xinyang's geographical and climatic features

Double advantages of temperature and humidity

A mild average temperature of 15℃ combined with 1900 hours of abundant sunlight creates a super-long growing period of 220 days for plants. The alternation of 75% air humidity in spring and 50% dryness in winter not only meets the needs of most flowers but also avoids the common diseases and pests found in tropical plants.

Key points of seasonal management

Special attention should be paid to soil drainage during the plum rain season, and it is recommended to use a 30cm deep gravel isolation layer. In winter, windbreak shelters should be built for evergreen plants such as camellias and cassias, and using straw mats can increase the surface temperature by 3-5℃.

Recommended list of suitable flower varieties

Advantageous perennial varieties

Crape myrtle, begonia, and hibiscus trees have prominent ornamental value throughout the year, with crape myrtle flowering for up to 120 days. Ground cover plants recommend a mix of scallion orchid and clover, which can inhibit weeds and maintain soil and water.

Seasonal ornamental combinations

In spring, forsythia and elaeagnus can be used to create a golden waterfall of flowers, in summer, lotus and water lilies can be combined to build an aquatic landscape, in autumn, cassia and chrysanthemum can form a fragrance matrix, and in winter, the red fruit combination of pyracantha and nandina has great visual tension.

Tips for cultivating characteristic city flowers and trees

Cultivation system of cassia

Choose cold-resistant varieties such as dan gui and jin gui, and add decomposed leaf soil to improve the soil during planting. Applying phosphorus and potassium fertilizers 30 days before flowering can increase the number of flowers, and attention should be paid to controlling red spiders by spraying matrine in advance.

Details of ginkgo care

Seedlings require sunshade net protection, and mature trees need to be fertilized in a circular pattern every winter. For the common ginkgo leaf blight, it is recommended to use a preventive spray of mancozeb 800 times solution.

By properly combining trees, shrubs, and herbaceous plants, Xinyang's courtyards can achieve a landscape effect of flowers in three seasons and greenery in all four seasons. Choosing native suitable varieties such as cassia and ginkgo not only has a high survival rate but also reflects the regional cultural characteristics. Regularly monitoring the soil pH (maintaining 5.5-6.5) and scientifically managing water and fertilization are key to maintaining healthy plant growth.
