• Abstract: This study aimed to evaluate the influence of a carbohydrate source (sucrose) and a biostimulant based on seaweed extract on the rooting of leaf cuttings of Kalanchoe blossfeldiana. The experiment was conducted in a completely randomized design with three treatments: control, sucrose solution (2 g L⁻¹), and biostimulant solution (5 mL L⁻¹), with eight replications and four cuttings per replication. After 30 days, the evaluated variables were rooting percentage, number of roots per cutting, and average root length. No significant differences were observed among treatments (p>0.05), with overall means of 80% rooting, 2.08 roots per cutting, and 0.43 cm average root length. The results indicate that K. blossfeldiana presents a high natural rooting capacity, not requiring the use of sucrose or biostimulant for vegetative propagation. However, these substances may be more effective in species with low rooting potential.
