The Cultivation Methods and Precautions of Pot-Grown Kalanchoe
Kalanchoe, with its beautiful flowers and tenacious vitality, has become a popular choice for home green plants. To make this succulent plant bloom brilliantly all year round, it is necessary to master scientific cultivation methods. This article systematically sorts out the complete maintenance system from soil proportioning to light management, helping you create a colorful balcony landscape.
Substrate Selection and Soil Mixing
High-quality cultivation substrate is the cornerstone of Kalanchoe growth. It is recommended to mix leaf mold soil, garden soil, and river sand in a ratio of 4:4:2. This combination can not only ensure nutrient supply but also form a loose and breathable root environment. The potting soil needs to be changed every two years to prevent soil compaction from affecting plant development.
Light Management System
Daily Light Requirements
In spring and autumn, ensure 4-6 hours of scattered light every day, and place the plant on an east-facing windowsill. In summer, use a shading net to filter strong light and avoid direct sunlight at noon to prevent leaf burn.
Winter Supplemental Lighting Plan
When consecutive rainy days exceed 3 days, use a plant growth lamp to supplement 2 hours of light every day, which can effectively prevent the vines from growing excessively. The supplemental lighting period should be arranged between 9-11 am to simulate the natural light cycle.
Water and Fertilizer Cooperative Management
Precise Irrigation Mode
Adopt the "dry-wet alternation" watering method, and water thoroughly after the top 3cm of soil dries. In winter, control water to once a week, and in the summer high-temperature period, it can be increased to once every 3 days, taking care to avoid water accumulation in the leaf heart.
Nutrition Cycle Control
In the growing period, apply a balanced liquid fertilizer with nitrogen, phosphorus, and potassium every 15 days, and switch to potassium dihydrogen phosphate solution (0.2% concentration) foliar application during the bud formation period. Stop fertilizing after flowering and rest, and resume fertilization when new buds sprout.
Through systematic environmental control, Kalanchoe can bloom multiple times throughout the year. The key is to grasp the balance between substrate permeability, light intensity, and nutrient supply. Regularly observe the plant's condition and adjust the maintenance strategy in a timely manner to ensure that this succulent plant shows its most brilliant life posture.
