🌿 Choose a healthy leaf: Select a mature leaf from the African Violet mother plant, preferably from the center of the plant.
✂️ Cut at an angle: Cut the leaf with a stem of approximately 3-5 cm, making the cut at a 45-degree angle.
🪴 Plant in moist soil: Place the leaf stem in a pot with light, moist soil, ensuring the cutting is in contact with the substrate.
💧 Maintain humidity: Cover the pot with a clear plastic bag to create a humid environment, but be sure to ventilate occasionally to avoid mold.
☀️ Indirect light and patience: Place the pot in a location with indirect light and wait 4-6 weeks for new plants to develop at the base of the leaf.

Summary: Propagating African Violet from a leaf is a simple process that requires a healthy leaf, proper cutting, and a humid environment for the development of new plants.
