When purchasing potted chili peppers, opt for varieties that are more cold-tolerant, such as小米椒 (小米 chili) and 朝天椒 (朝天 chili). These varieties can maintain a relatively good growth state in low-temperature environments. It is important to select healthy plants that are free from diseases and pests.
Adjust Lighting and TemperatureChili peppers enjoy sunlight, but in winter when there is insufficient sunlight, it is necessary to adjust the lighting time. Place the potted chili peppers in a well-lit indoor area, such as a balcony or windowsill, and maintain an indoor temperature of above 15℃ to prevent the peppers from freezing.
Control WateringIn winter, the lower temperature slows down the growth rate of chili peppers, reducing their water requirement. Watering should follow the "water when dry" principle to avoid overwatering that could lead to root rot. Water the plants only when the surface of the soil is dry, keeping the soil slightly moist.
Fertilization ManagementIn winter, the growth rate of chili peppers is slower, and their ability to absorb fertilizer is also reduced. Fertilization should be moderate to avoid excessive growth due to too much fertilizer. A low-nitrogen, high-phosphorus and potassium compound fertilizer can be used, applying once a month.
Pruning and VentilationIn winter, it is appropriate to prune the plants, removing sick, weak branches, and yellow leaves to maintain good ventilation and light penetration. Keep the indoor air circulation to prevent diseases caused by humidity.
Disease and Pest ControlThe warm and humid indoor environment in winter can easily trigger diseases and pests. Regularly inspect the plants and deal with any diseases or pests promptly. Use biological pesticides or low-toxicity pesticides for control to avoid using highly toxic ones.
Storing Chili PeppersWhen the chili peppers are mature, pick them and place them in a well-ventilated and dry area to dry. Dried chili peppers can be stored for a long time, which is convenient for consumption in winter.
By managing these seven aspects, your potted chili peppers can safely survive the cold winter, bringing you the joy of a bountiful harvest. Growing flowers requires patience and care. I hope you continue to accumulate experience in the process and ensure your potted chili peppers grow robustly!
