8. Red Vanda : Propagation By Seeds: Seedpod of orchid grow after fertilization, and ripens in 6 months to 1 year After ripening the seeds are collected and stored in a cool and dry place or in a desiccator Under natural condition, the seeds germinate S eedlings grown in a flask of culture media containing agar, inorganic nutrients and sugar .

9. Red Vanda : Propagation By Seeds: Seedlings grow for 8 to 12 months before they are transferred. After flask seedlings transferred to the community pots of 7 to10 cm in diameter which hold about 20 to 25 small plants. A shady but well aerated location with high humidity in the greenhouse will promote the growth of seedlings Watering: Daily in normal seasons and 2-3 times in summer by spraying. Alkaline water is injurious to orchids and slight acidic water or at pH up to 7 should be used.

10. Red Vanda : Propagation By Vegetative Propagation: Commercial Method of Propagation P ropagation is done by cutting As these large-sized plants produce adventitious roots, the stem is cut in section 3 to 4 nodes Cutting are usually potted in propagation beds or directly in pots after treating the cut ends with fungicides to prevent rotting. Placed in a cool and dry place for healing of wound and allowed to root in moist sand or damp sphagnum moss

11. Red Vanda : Propagation Nutrients: A balanced feed on nitrogen, phosphate and potash in the ratio of 10:12:10 In addition with  very small amount of magnesium, calcium, manganese, iron, boron and zinc Mixture: Two table spoonful of the above fertilizers mixed in 10 ltrs of water Sprayed once a week on plants

12. Red Vanda : Propagation Climatic factors: Temperature : can survive in 13 C to 35 C but 18 C to 30 C is ideal. Watering: Daily/ 2-3 times in summer Humidity: 80% is ideal during day time and minimum 30% during night. Sunlight: Indirect sunlight is idle for orchids. The light should be very bright, but it will be beneficial to filter the sun at noon
