How to care for a newly bought golden-edged winter daphne, and what is its minimum cold-hardiness temperature?
I believe many people enjoy growing flowers, because growing flowers can please oneself and thereby have a healing effect. In recent years, with the development of science, many native flowers loved by gardeners have been bred into new cultivars. Among them, of course, is the internet-famous "golden-edged winter daphne"; it is not only grown for its flowers but also for its foliage, and the flowers it produces also have a rich fragrance, which can be said to have captivated many new and veteran gardeners alike.
Golden-edged winter daphne is also called Xiang and Penglai flower, among other names. Although quite a few gardeners still do not know it, it is in fact a traditional famous flower of our country. When browsing the flower market, you can easily find it. In terms of care, winter daphne likes a warm, humid and cool environment, and is neither cold-tolerant nor heat-tolerant. When the temperature drops below 10 degrees, the flowerpot should be moved indoors; when the temperature reaches over 20 degrees, it will show sluggish growth, and at this time direct sunlight should be avoided.
As for soil, potted winter daphne is not very demanding about soil; choosing fertile, acidic soil is enough. Generally, it is recommended to repot once every two to three years, and the recommended seasons for repotting are spring and autumn. As for its daily placement, it can be changed according to the season. Although winter daphne likes partial shade, in winter and spring it is recommended to keep it in a spot on the south side that receives sunlight; in summer, when it is relatively hot, it can be placed in a well-ventilated, shady spot, while also misting water around it more to cool it down.
As for watering, winter daphne does best when the soil is kept slightly dry. The watering standard should change according to the season: in summer, when it is hot, choose to water once each in the morning and evening; in spring and autumn, when it is relatively cool, watering can be reduced to once every time needed, but during the autumn bud stage, be careful not to let the potting soil become too dry, and during the rainy season, move it back indoors in time to avoid rain and reduce the occurrence of pests and diseases.
In addition, the roots, leaves, stems and petals of the golden-edged winter daphne are all treasures; basically the entire plant contains daphnetin, which reduces swelling and relieves pain, clears heat and detoxifies, and disperses blood stasis and invigorates blood flow. Its flower extract is also believed to be usable in treating conditions such as mastitis, toothache and sore, swollen throat. Besides this, its branches and stems are also a good raw material for papermaking.
