Florist Kalanchoe (Kalanchoe blossfeldiana) is a popular succulent known for its vibrant, long-lasting flowers and relatively easy care requirements. These plants, native to Madagascar and tropical Africa, feature fleshy leaves that store water, contributing to their drought tolerance. Propagating Kalanchoe allows gardeners to expand their collection, share plants with others, or simply rejuvenate an older plant, all while saving money. Stem cuttings are a straightforward and effective method for creating new Kalanchoe plants.
Best Time for Propagation
The optimal time for propagating Florist Kalanchoe from cuttings is in late spring and summer after flowering. Increased daylight and warmer temperatures (65-75°F / 18-24°C) during these months encourage robust root development. This timing allows the parent plant to focus energy on new growth, promoting faster recovery. While indoor propagation is possible year-round, spring and early summer yield the most successful results.

Gathering Your Tools
Gathering the right materials is essential for successful propagation. You will need:
A healthy Kalanchoe plant for cuttings.
Sharp, clean pruning shears or scissors to ensure precise cuts and prevent disease transmission.
Small pots with drainage holes.
A well-draining succulent or cactus potting mix.
Rooting hormone powder (optional, for faster root development).
Taking the Cutting
Select a healthy, non-flowering stem from the parent plant, at least 2-3 inches long with several leaves. Make a clean cut just above a leaf node, the small bump on the stem where leaves or branches emerge. This cut encourages new growth on the parent plant and provides a starting point for roots on the cutting.
Preparing the Cutting
After taking the cutting, remove leaves from the bottom inch or two of the stem to expose nodes where roots will form. Allow the cut end to dry and form a callus before planting; this typically takes 2-7 days. Callousing helps prevent rot and disease once the cutting is placed in soil. If using rooting hormone, apply it to the calloused end just before planting.
Planting the Cutting
Fill pots with a well-draining succulent or cactus potting mix. Create a small hole (half an inch to an inch deep) in the center of the soil. Gently insert the calloused cutting, ensuring the bottom leaf is just above the soil line, and lightly firm the soil around the stem. After planting, mist the soil lightly for initial moisture, avoiding excessive wetness to prevent rot.
Caring for Your New Kalanchoe Plants
Once your Kalanchoe cuttings are planted, place the pots in a location that receives bright, indirect light. Direct sunlight can scorch the delicate new cuttings, so a south or west-facing window is often ideal. Maintain consistent, moderate temperatures, generally between 55-80°F (13-27°C), avoiding extreme fluctuations.
Water newly planted cuttings carefully to prevent rot. Allow the soil to dry out completely between waterings, checking moisture by inserting your finger an inch or two into the soil. When dry, water thoroughly, allowing excess water to drain. Overwatering is a common cause of failure, as Kalanchoe are highly susceptible to root rot in soggy conditions.
Troubleshooting Propagation Issues
Common issues can arise during Kalanchoe propagation. If cuttings rot, it is often due to overwatering or insufficient callousing before planting. Ensure the cut end has adequately dried and the soil is not overly moist to prevent this problem.
Failure to root or slow growth might indicate inadequate light or incorrect temperatures. Moving the cuttings to a brighter, indirectly lit location and ensuring consistent warmth can stimulate root development. While Kalanchoe cuttings typically root within a few weeks, patience is important, as some may take longer to establish.
