Introduction
Cymbidium orchids, also known as “boat orchids,” are a popular choice for indoor and outdoor gardens due to their vibrant flowers and relatively easy care requirements. Properly caring for the bulbs, or pseudobulbs, is essential for ensuring healthy growth and abundant blooms. This article will focus on the key steps for repotting and dividing Cymbidium orchid bulbs to promote their long-term success.
Repotting Cymbidium Orchid Bulbs
Timing and Pot Selection
- Repot Cymbidium orchids every 2-3 years, typically in the spring when new growth is visible.
- Use a pot that is slightly larger than the current one, allowing for about 1-2 inches of additional space around the bulbs.
- Ensure the pot has excellent drainage to prevent root rot.
Potting Mix
- Use a well-draining, acidic potting mix specifically formulated for orchids.
- A mix of fir bark, perlite, peat moss, and other organic materials works well.
Repotting Steps
- Gently remove the plant from the existing pot, being careful not to damage the roots.
- Inspect the roots and remove any dead or damaged portions.
- Place the plant in the new pot and fill in around the sides with the fresh potting mix.
- Water the plant thoroughly, making sure the potting mix is evenly moist but not waterlogged.
Dividing Cymbidium Orchid Bulbs
When to Divide
- Divide Cymbidium orchids when repotting, typically every 2-3 years.
- Division is best done in the spring when the plant is actively growing.
Division Process
- Carefully remove the plant from the pot and gently separate the individual bulbs, ensuring each division has at least 3-4 mature pseudobulbs and one new growth.
- Handle the roots with care, avoiding excessive trimming of live roots.
- Plant the divided sections in individual pots, using the same well-draining potting mix.
- Water the divided plants thoroughly and place them in a shaded area for a few weeks to allow the roots to establish.
Additional Tips
- Maintain a humid environment, especially during the winter months, to support healthy growth.
- Prune back flower stems to the base after blooming and remove any dead or dying leaves or pseudobulbs.
- Monitor for pests, such as spider mites, slugs, and snails, and treat with insecticidal soap if necessary.
- Adjust watering and fertilization as needed to address any disease issues, such as root rot or leaf scorch.
By following these guidelines for repotting and dividing Cymbidium orchid bulbs, you can ensure the long-term health and vibrant blooms of your plants.
