Everything it needs
9 essentials at a glance
Watering
Kalanchoe Blossfeldiana prefers to dry out between waterings.
Water thoroughly when the top inch of soil feels dry, typically every 2-3 weeks. In winter, reduce watering to once a month. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause leaves to shrivel and drop.
Light
This plant thrives in bright, indirect sunlight but can tolerate some direct sun.
Ideally, it should receive 6-8 hours of light daily. Avoid placing it in full shade, as this can lead to leggy growth and poor flowering.
Soil
Kalanchoe prefers well-draining soil with a pH of 6.0 to 7.0.
A cactus or succulent potting mix is ideal, or you can create your own by mixing regular potting soil with sand and perlite to enhance drainage.
Humidity
Kalanchoe Blossfeldiana thrives in average household humidity levels (40-60%).
To increase humidity, you can place a humidity tray filled with water and pebbles beneath the pot. Signs of low humidity include leaf curling and browning tips.
Temperature
The ideal temperature range for Kalanchoe is 65-80°F (18-27°C).
It is hardy in zones 10-12 and can tolerate brief periods of cooler temperatures down to 50°F (10°C), but prolonged exposure can damage the plant.
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 10-10-10, diluted to half strength.
Fertilize every 4-6 weeks during the growing season (spring and summer). Signs of nutrient deficiency include yellowing leaves and poor growth.
Pruning
Prune Kalanchoe after flowering to encourage bushier growth.
Use clean, sharp scissors to remove spent flowers and any leggy stems. Deadheading can be done regularly to promote new blooms.
Repotting
Repot Kalanchoe every 2-3 years or when it outgrows its pot.
Choose a pot one size larger with drainage holes. Signs it needs repotting include roots growing out of the drainage holes and stunted growth. Carefully remove the plant, refresh the soil, and place it in the new pot.
Propagation
Propagation can be done through leaf cuttings or offsets.
For leaf cuttings, take a healthy leaf, allow it to callous for a few days, then place it in well-draining soil. Water lightly until roots develop. The best time for propagation is in spring or early summer.
