What flowers are suitable for cultivation in Qingdao
In Qingdao, located on the shore of the Yellow Sea, the moist sea breeze and the temperate monsoon together create a unique planting environment. With an average annual temperature of 12.3℃ and 1100 mm of precipitation, it becomes a natural greenhouse for flower growth. However, the special marine climate also brings challenges such as salt fog erosion and large temperature differences between winter and spring, so choosing the right variety can make the garden flourish all year round.
Choices of plants for courtyard planting
Salt and alkali tolerant pioneer varieties
The coastal soil is generally alkaline, and plants such as magnolia, crape myrtle, and forsythia perform well. Among them, the purple leaf plum not only tolerates salt and alkali but also has purple-red leaves that can be admired for 200 days, creating a color contrast landscape with golden leaves elaeagnus. It is recommended to dig a pit 60 cm deep when planting and lay a 10 cm layer of碎石 at the bottom to enhance drainage.
Four-season ornamental sequence combination
Early spring forsythia and Ulmaceae lead the way, followed by lilacs and begonias in April, hydrangeas and dahlias in the summer, and pyracantha red fruits that can stay on branches until the Spring Festival. Hydrangea is especially recommended, which can reach a crown width of 1.5 meters in Qingdao's humid environment, extending the flowering period to 45 days.
Balcony pot cultivation plan
Indoor and outdoor transition strategy
Tricolor Jasmines need to be brought indoors below 10℃, but it should be noted that in heated rooms, they should be kept more than 2 meters away from the radiators. It is recommended to use red pottery pots to plant succulents, as their breathability can prevent root rot caused by coastal humidity. You can try clematis on a south-facing balcony, and pair it with an automatic drip irrigation system to solve the watering problem when you are away on business.
Special pot plant recommendation
Fuchsia series shade-tolerant varieties are suitable for north-facing balconies, with rainbow leaf colors that can last for 10 months. Air plants do not require potting soil and can be watered twice a week with a mixture of 2 parts seawater and 3 parts tap water. The recently popular "Bao Lian Deng" flowers perform well in Qingdao, with attention to maintaining a 60% shading rate.
From the rose flower walls of Badaguan to the tea gardens of Laoshan, Qingdao people have long mastered the wisdom of coexisting with nature. Choosing salt-tolerant trees as the framework, combined with wind-resistant shrub layers, and finally filling the gaps with perennial flowers, this 'tree-shrub-ground cover' three-layer configuration method is both scientific and aesthetically pleasing. Remember to regularly test the soil with pH test paper to allow each plant to find its own ecological niche on the shore of the Yellow Sea.
