Xian Dan flower is a type of evergreen shrub that can bloom throughout the year. Its flowers cluster together and look very beautiful. This plant is drought-resistant and heat-tolerant, making it easy to cultivate. However, to grow Xian Dan flowers well, one must learn the cultivation methods. Proper methods will ensure the plant grows robustly. Let's discuss the cultivation methods for Xian Dan flowers.
One, Potting Soil Selection
When cultivating Xian Dan flowers, it is best to choose unglazed clay pots, as they have good permeability. The potting soil should be loose and fertile, with a high content of humus, and the soil's pH value should be maintained between 5 and 6.5. Many gardening enthusiasts prefer to mix their own growing soil, which consists of decomposed leaf mold, sandy loam, and river sand in a ratio of 2:2:1. Some well-rotted soybean cake meal or rapeseed meal can be added to the growing soil, and some gardeners place hoof meal at the bottom of the pot as a base fertilizer.
Two, Temperature Requirements
A temperature range of 15 to 25 degrees Celsius is most favorable for the growth of Xian Dan flowers. Between March and September, the temperature should be controlled between 24 and 30 degrees Celsius. From September to the following March, the temperature should be maintained between 13 and 18 degrees Celsius. The temperature in winter should be above 0 degrees Celsius.
Three, Fertilization Requirements
Xian Dan flowers enjoy fertilizer. During their growing period, a balanced NPK compound fertilizer should be applied every two weeks. From mid-April to early May, apply twice the well-rotted soybean cake water. From mid-May to the budding period, apply twice the well-rotted nitrogen-phosphorus liquid fertilizer. During the blooming period, apply twice the well-rotted phosphorus liquid fertilizer.
Four, Watering Requirements
Water Xian Dan flowers according to the "moist when dry" principle. In spring, water once every four days. In summer, water every one or two days with soft water, and sprinkle water around the plant twice a day, morning and evening, to increase humidity. During the growing season, water once a week with an iron sulfate fertilizer solution to make the leaves greener.
Five, Light Requirements
In summer, when temperatures are too high, it is necessary to provide some shade. After autumn, it is important to increase the duration of sunlight exposure.
Six, Proper Pruning
In early winter, pruning of the Xian Dan plant should be done to remove diseased, dense, and weak branches, while strong branches should be retained. After pruning, it is also necessary to do pinching. When the seedlings reach about 18 centimeters in height, pinching should be done once. After flowering, pruning should also be done. Every spring, the potted Xian Dan flowers should be repotted with new soil. For overwintering old plants, leave about 20 centimeters and do a severe pruning.
Seven, Pest and Disease Control
During the growth of Xian Dan flowers, leaf spot or anthracnose may occur, and appropriate fungicides should be sprayed for prevention and control. If there are scale insects on the plant, they can first be wiped with a damp cloth. If the number is particularly large, apply dimethoate. If there are aphids, apply pyrethrin.
