The maintenance difficulty of the red color of wintersweet (usually referring to red wintersweet or red heart wintersweet) is relatively moderate. As long as certain maintenance techniques are mastered, it can bloom into beautiful flowers from winter to spring. Here are some key points about maintaining the red color of wintersweet: 1. Growing environment
Light: Chimonanthus prefers sunny environments, but it can also tolerate shade. During the growth period, it is necessary to ensure that wintersweet receives sufficient sunlight exposure, but avoid prolonged exposure, especially during high temperatures in summer, where appropriate shading is needed to prevent leaves from getting sunburned.
Soil: The requirements for soil for wintersweet are not strict, but loose, fertile, and well drained sandy loam soil is preferred. Before planting, one can choose soil rich in organic matter and add an appropriate amount of humus or perlite to improve soil permeability and water retention.
Temperature: wintersweet prefers a warm and humid climate, but is not tolerant to high temperatures and extreme cold. During low temperatures in winter, it is important to take measures to keep warm. Plants can be moved indoors or insulated to prevent freezing damage. 2. Water management
Lame prefers a moist environment, but excessive watering can easily lead to root rot. When watering, follow the principle of "see dry, see wet", that is, water thoroughly, but do not let the soil in the pot stay moist for a long time.
During the growing season (spring and summer), the soil should be kept moist and watering should be increased in a timely manner to meet the growth needs of the plants. In autumn and winter, watering frequency should be reduced to avoid frost damage. 3. Fertilization management
Plum requires sufficient nutrients during its growth period. During the vigorous growth period in spring and autumn, mature organic fertilizer or compound fertilizer can be applied every half month to promote plant growth.
Before the flowering of wintersweet, the application of phosphorus and potassium fertilizers should be increased to promote flower bud differentiation and flower opening. However, it is important to control the amount of fertilizer applied to avoid excessive fertilization that can cause root burning. 4. Trimming and shaping
Proper pruning can promote the ventilation, transparency, and aesthetics of wintersweet. During the growth period, branches that are too dense, too long, or diseased should be pruned regularly to maintain the healthy growth status of the plant.
After the flowering of wintersweet, residual flowers and dead leaves should be cut off in a timely manner to avoid nutrient consumption. At the same time, pruning can be used to adjust the plant shape and height of wintersweet to make it more beautiful. 5. Disease and pest control
Common pests and diseases of wintersweet include powdery mildew, anthracnose, aphids, and scale insects. During the maintenance process, it is important to regularly check the growth status of the plants and take timely preventive measures such as spraying insecticides if any pests or diseases are found.
At the same time, attention should be paid to preventing the occurrence of diseases, such as strengthening the ventilation and transparency of plants, reducing humidity, etc., to reduce the probability of disease occurrence.
The maintenance of the red color of wintersweet is not complicated. As long as you master the above maintenance points and take care of it carefully, it can bloom beautifully from winter to spring, adding a warm color to the cold season.
