Suitability of Huai'an Climate for Flowers
Unique Advantage of Alternating Temperature and Humidity
An annual average temperature of 14℃ combined with 1000mm of precipitation creates the typical characteristics of spring moisture, summer humidity, autumn coolness, and winter cold. This temperature and humidity variation makes Huai'an a natural testing ground for both north and south flowers, where both the grandeur of northern peonies and the delicate beauty of southern camellias can be seen.
Key Points for Soil Improvement
The yellow-brown soil, which is the main soil type, needs to be mixed with humus soil to enhance fertility. For acid-loving plants like wintersweet, pine needle soil can be mixed in. For flowers that prefer slightly acidic conditions, such as roses, it is recommended to apply ferrous sulfate every quarter to adjust the pH value.
Selected Plant Growth Guide
Preferred Courtyard Flowers
Lilacs and Chinese redbud form an early spring flower corridor, while hibiscus and crape myrtle take over the summer and autumn landscape. The red oxalis, known for its strong resistance, is especially recommended as a ground cover plant, utilizing its shade-tolerant characteristics to make full use of courtyard corners.
Planting Solutions for Balconies
