Leaf-Cutting-Propagation: method
Quick answer
method for Leaf-Cutting-Propagation: Leaf cuttings root via wound-induced meristematic activity. When a leaf is detached and placed in contact with moist medium, wound signals trigger dedifferentiation of parenchyma cells near veins into meristemoids. These form adventitious roots first, then shoots — the leaf blade provides carbohydrates for the initial recovery phase while roots develop.
Start here:
- 1. For leaf-petiole cuttings (African violet, begonia): select mature leaf with 2-inch petiole; cut cleanly 1 inch from blade
- 2. Insert petiole vertically into moist perlite/peat mix, leaving blade above surface at 45° angle

How to handle method on Leaf-Cutting-Propagation
- 1
For leaf-petiole cuttings (African violet, begonia): select mature leaf with 2-inch petiole; cut cleanly 1 inch from blade
- 2
Insert petiole vertically into moist perlite/peat mix, leaving blade above surface at 45° angle
- 3
For leaf-blade cuttings (snake plant, Streptocarpus): cut leaf into 3-5cm squares or 2-inch strips each containing a main vein
- 4
Place squares flat on moist medium, pressing firmly to ensure contact
- 5
Cover with humidity dome; maintain 70-75°F; roots form in 4-8 weeks, shoots emerge 2-4 weeks later
- 6
Pot individual plantlets once they have 2-3 leaves and visible roots
Keeping Leaf-Cutting-Propagation on track
Use healthy, turgid leaves from actively growing plants; maintain >80% humidity to prevent desiccation; use rooting hormone on petiole cuts to accelerate root initiation.
