Kalanchoe

SCENTIFIC NAME: Kalanchoe Blossfeldiana

KNOWN AS: Kalanchoe, Widow's Thrill, Christmas Kalanchoe

CLIMATE (LOCATION): Madagascar & Africa | Arid

DESCRIPTION: The Kalanchoe is a popular succulent cherished for its thick, waxy leaves and long-lasting, vibrant flowers that bloom in shades of red, pink, yellow, and orange. Known for its drought tolerance and low-maintenance nature, it is a great choice for adding a burst of color to any room.

Kalanchoe Plant Care

Lighting

Light Requirement: High Light (Bright Indirect Light)

The Kalanchoe thrives in bright, indirect light. It needs plenty of light to bloom, so a south- or west-facing window is ideal. While it can tolerate some direct sun, be careful with intense afternoon light, which can scorch its leaves. To re-bloom, the plant requires a period of 12-14 hours of complete darkness each night for 6-8 weeks in the fall.

Watering

Quick Tip: Allow soil to completely dry out before watering.

As a succulent, the Kalanchoe stores water in its leaves and is very susceptible to overwatering, which is the most common cause of root rot. Water thoroughly only when the soil is completely dry to the touch. Reduce watering significantly during the dormant winter months.

Temperature

Preferred Temperature: 60º - 85º

The Kalanchoe prefers warm, stable temperatures. The ideal range is between 60-85°F. It is sensitive to cold and should be kept away from temperatures below 50°F and from drafts.

Humidity

Preferred Humidity: 30 - 50%; Low/Moderate Humidity

The Kalanchoe is a desert succulent and prefers a low to moderate humidity environment. The average humidity of most homes is perfect for this plant, and you do not need to take any special steps to increase it.

Additional Plant Care

Propagation
The Kalanchoe is very easy to propagate by stem cuttings, leaf cuttings, or offsets. Take a cutting and allow the cut end to form a callus for a few days before planting it in a well-draining soil mix. A single leaf can be planted in moist soil and will root. Some varieties produce small offsets from the leaves that can be easily removed and planted.
Toxicity
The Kalanchoe is toxic to pets.The plant contains cardiac glycosides (bufadienolides) that can cause vomiting, diarrhea, and in rare cases, an abnormal heart rhythm if ingested by cats and dogs. It is important to keep this plant out of reach of pets.
Repotting
Repotting a Kalanchoe is a minimal task. Repotting is typically only necessary every 1-2 years, or when the plant has completely outgrown its container. Select a new pot that is only slightly larger and has drainage holes. Use fresh, well-draining soil and carefully place the plant in the new pot, filling in the sides with fresh soil.
Pruning
Pruning is a simple task to keep your Kalanchoe looking its best. Trim away any spent flowers, dead leaves, or leggy stems. Use clean shears to cut the stem off at the base. This redirects the plant's energy and encourages a fuller plant.
Fertilizer
Kalanchoes do not require a lot of fertilizer. A balanced, water-soluble fertilizer diluted to half strength is ideal. Fertilize once a month during the spring and summer growing season. Do not fertilize during the fall and winter.
Soil
The right soil is crucial for a healthy Kalanchoe. The plant requires a well-draining soil mix to prevent root rot. A good mix is cactus or succulent potting mix amended with extra perlite or coarse sand. Always use a pot with a drainage hole to ensure excess water can escape.

Kalanchoe Lighting Requirements: High Light (Bright Indirect Light)

Living in New York City often means making compromises, but your plant collection shouldn’t be one of them. Whether you are dealing with a classic Manhattan "brick-wall view," a narrow Brooklyn railroad layout, or deep Queens window sills, the struggle for natural light is a universal urban experience.

Understanding whether your plant is thriving or merely surviving often comes down to one factor: light. Because plants use light as their primary fuel source, a lack of it causes the plant to stall and eventually decline.

For years, indoor gardening often meant hiding unsightly purple-hued equipment in basements or behind furniture. However, a significant shift in interior design has transformed plant care into a centerpiece of the home. Modern interior designers are no longer tucking grow lights away; they are treating them as intentional, sculptural elements that define the atmosphere of a room.
