Kalanchoe blossfeldiana ‘White’ is a popular, easy-to-care-for succulent, cherished for its vibrant, long-lasting blooms. Originating from Madagascar, this plant provides continuous color for several weeks. It features thick, waxy, deep green leaves and clusters of small, four-petaled white flowers. This resilient houseplant offers attractive foliage and abundant floral displays, making it a delightful addition to any home.
Kalanchoe Blossfeldiana White Care
Light
Adequate light is important for the health and flowering of Kalanchoe blossfeldiana ‘White’. These plants thrive in bright, indirect light, such as near an east-facing window. Sufficient light encourages robust growth and abundant flower production. Direct, intense afternoon sunlight should be avoided, as it can scorch the waxy leaves. Conversely, insufficient light results in leggy, stretched stems and reduced blooms.
Water
Proper watering is crucial for Kalanchoe blossfeldiana ‘White’, given its succulent nature and susceptibility to root rot. The soil should dry out completely between waterings, typically by feeling the top inch or two. Overwatering is a common issue, leading to soft, mushy stems or yellowing leaves. Underwatering can also harm the plant, indicated by wilting or shriveling leaves, though the plant usually recovers.
Soil
The ideal soil for Kalanchoe blossfeldiana ‘White’ must provide excellent drainage to prevent root waterlogging. A specialized succulent or cactus potting mix is recommended, designed to be porous and fast-draining. Alternatively, a standard potting mix can be amended with perlite, coarse sand, or pumice to enhance drainage. Good drainage is essential, preventing excess moisture that can lead to root diseases.
Temperature and Humidity
Kalanchoe blossfeldiana ‘White’ prefers average room temperatures, typically 60 to 75 degrees Fahrenheit (15 to 24 degrees Celsius). Maintaining these temperatures supports healthy growth and flowering. Protect the plant from sudden temperature drops, cold drafts, and frost, as these can cause chilling injury. Kalanchoes tolerate average household humidity and do not require additional humidity, making them well-suited for indoor environments.
Fertilizer
During its active growing season (spring and summer), Kalanchoe blossfeldiana ‘White’ benefits from regular, light fertilization. Apply a balanced liquid fertilizer, diluted to half strength, every two to four weeks. This provides necessary nutrients for vigorous foliage and bloom production. Reduce or stop fertilization during the plant’s dormant period in winter or while it is actively flowering.
Encouraging Reblooming
Encouraging Kalanchoe blossfeldiana ‘White’ to rebloom requires understanding its short-day flowering cycle. The plant initiates flower buds with prolonged darkness, mimicking its natural conditions.
To stimulate reblooming, starting in late fall, provide 14 to 16 hours of uninterrupted darkness daily for six to eight weeks. This can be achieved by placing the plant in a closet or covering it. During this dark period, the plant should receive bright light for the remaining 8 to 10 hours.
Maintaining a consistent temperature, ideally around 60 degrees Fahrenheit (15 degrees Celsius), during the dark treatment aids flower bud formation. Watering should be slightly reduced during this reblooming induction phase, ensuring the soil remains barely moist. Once flower buds begin to form, usually within a few weeks, return the plant to its regular light and watering schedule.
Propagating Kalanchoe Blossfeldiana White
Propagating Kalanchoe blossfeldiana ‘White’ is straightforward, primarily through stem cuttings. Select a healthy, non-flowering stem 3-5 inches long, cutting just below a leaf node. Remove lower leaves to expose the stem.
Allow the cut end to dry and form a callus for a few days; this prevents rot when planted. After callusing, plant the cutting in a well-draining potting mix, such as a succulent or cactus blend.
Water lightly and place the pot in bright, indirect light, maintaining temperatures around 70 degrees Fahrenheit (21 degrees Celsius). Roots typically develop within a few weeks, allowing care as a mature Kalanchoe. Leaf cuttings can also be used, though they generally take longer.
Common Issues and Solutions
Common issues can affect Kalanchoe blossfeldiana ‘White’, often related to environmental stress or pests. Root rot, a frequent problem, usually stems from overwatering, identified by mushy stems and yellowing leaves. To remedy this, allow the soil to dry completely between waterings and ensure the plant is in a pot with drainage holes.
Leggy growth, characterized by stretched stems and sparse foliage, indicates insufficient light, necessitating a move to a brighter location. Fungal issues like leaf spot appear as small, dark spots, often due to excessive humidity or poor air circulation. Improving air flow and avoiding overhead watering helps prevent this.
Common pests, such as aphids or mealybugs, may occasionally infest Kalanchoes, appearing as sticky insects or cottony masses. Control them by wiping with rubbing alcohol or using insecticidal soap spray.
