In contrast to the tricky sowing of seeds, the vegetative propagation of orchids is uncomplicated and promising. Read here which orchids are suitable for this form of breeding. This is how you share the exotic plants professionally.
If the orchid is large enough, it can be best propagated by division
Which orchids are suitable for division?
Within the large orchid family, a rough distinction is made between monopodial and sympodial species. Monopodial describes the growth with an axis whose growth takes place exclusively at the top. These include Phalaenopsis or Vanda orchids. It is obvious that a single shoot axis cannot be divided without destroying the plant.
Sympodial orchids, on the other hand, thrive with multiple bulbs or shoots connected by a rhizome. Classic representatives of this growth form are the genera Cymbidium, Oncidium or Brassia. Almost all species and varieties of sympodial orchids are suitable for propagation by division.
How to properly divide an orchid
If repotting an orchid is on the care plan in spring, this is also the best time for division. Water, dip and fertilize the plant a day or two before the appointment to keep the aerial roots supple. In these steps you divide the root ball:
- Unpot the root ball and remove the substrate
- Pull the roots apart with both hands so that there are 2 parts with at least 2 bulbs each
- If necessary, cut up a stubborn root ball with a disinfected scalpel
- Take this opportunity to cut off dead aerial roots
Immediately afterwards, pot each segment with at least 2 or 3 bulbs in a separate culture pot. Fill in fresh orchid soil so that all roots are covered. It is helpful to hit the pot several times on the tabletop.
tips
Freshly divided and potted orchids should be able to regenerate in peace. To do this, refrain from watering or submerging the plants for the first 5 days. It is better to spray the leaves and aerial roots daily with filtered rainwater.
