Cultural practices
Orchids need repotting regularly, usually every two to three years.
1. When the plant grows large and overgrows its container.
2. When the potting material deteriorates
3. When the plant has to be split or divided
4. It is better to repot epiphytes every year.
The best time for repotting is when fresh roots emerge at the bases of the previous year’s growth. In monopodial climbers, repotting or division has to be done when new leaf growth shows at the top and there is new root growth.
Foliar application of GA3 50 ppm at bimonthly intervals starting from 30 days after planting.
