To root a vanilla orchid, use damp sphagnum moss and carefully position the bottommost aerial roots across the media.
Here's a more detailed guide:
-
Prepare the Potting Medium: A shallow but fluffy layer of damp sphagnum moss provides the ideal environment for root development. Avoid using regular potting soil, as it retains too much moisture and can lead to rot.
-
Position the Aerial Roots: Gently lay the bottommost aerial roots of your vanilla orchid across the prepared sphagnum moss.
-
Cover the Roots (Partially): Do not bury the cut end of the orchid completely. Instead, layer more sphagnum moss over the roots in the container. This helps to keep them moist and encourages growth.
-
Maintain Humidity and Warmth: Vanilla orchids thrive in humid environments. Consider placing the potted orchid in a propagator or covering it with a clear plastic bag to increase humidity. Maintain a warm temperature, ideally between 70-85°F (21-29°C).
-
Water Carefully: Keep the sphagnum moss consistently damp, but not waterlogged. Overwatering can lead to root rot. Water when the top layer of moss feels slightly dry.
-
Provide Indirect Light: Place the potted orchid in a location with bright, indirect light. Avoid direct sunlight, which can scorch the leaves.
-
Be Patient: Root development can take several weeks or even months. Observe the orchid regularly for signs of new growth. As the plant matures, air roots will appear above the soil line.
