A Detailed Guide to Kalanchoe Propagation and Seedling Methods: Easily Grow Robust Seedlings
Kalanchoe is mostly propagated by asexual methods; besides cuttings, tissue culture is also widely used. There are two types of cuttings: leaf cuttings and tip cuttings. Generally, leaf cuttings and tissue culture are mostly used for producing stock plants; tip cuttings are mostly used for pot flower production.
In pot flower production, unrooted cuttings are generally inserted directly into the pots where they will ultimately be planted, so the growing medium and the rooting medium are the same: peat and perlite mixed at a ratio of 7:3, with the pH of the medium adjusted to between 5.5 and 6.0. Growers can adjust the ratio according to water quality, the variety being grown, and the production season, or add vermiculite, sand, and other soilless media to create a well-drained medium with moderate nutrient content.
1. Leaf cuttings. Remove the entire leaf (the larger the leaf, the better), place it in a shady spot to let the wound dry, and after several hours insert the petiole completely into the moist medium. If the petiole is too short, part of the leaf blade can also be inserted into the medium in place of the short petiole. At this stage, do not keep it too wet, to avoid the leaf becoming diseased and rotting.
After inserting the cutting, place it in a spot with slightly weak sunlight, keeping the temperature between 20°C and 25°C. After 3 to 4 weeks, roots begin to form, at which point it can be placed under full sun and given a low-concentration fertilizer. After another 7 to 10 weeks, seedlings differentiated from callus tissue will become visible. Once the seedlings grow to 15 to 20 cm, they can be separated from the leaf and grown on their own, while the leaf can continue to produce more seedlings. The separated seedlings can be used as stock plants for producing unrooted cuttings.
2. Tip cuttings. Use the prepared stem tip as the cutting, insert it directly into a pot filled with medium, keep the medium moist, avoid overly strong light intensity, and maintain the temperature between 20°C and 25°C. Roots will form in about 2 to 3 weeks, after which the plants can enter production-period management. Tip cuttings are generally mostly used for pot flower production (Note: Kalanchoe is a typical long-day flowering plant; during cutting propagation, the day length must be longer than 12.5 hours, and when propagating by cuttings in winter, supplemental lighting must be provided).
