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
– Seedlings 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
– Propagation 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 130C to 350C but
180C to 300C 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

13. Red Vanda : Propagation
• Fungal and bacterial Diseases
– Leaf spot - caused by Colletotrichum and
Gleosporium
– Leaf blight - caused by Pythium
– Collar blotch - caused by Penicilium thomii
– Collar rot - caused by Sclerotium
– Orchid wilt - caused by Sclerotium rolfsli
