Repotting a Cymbidium orchid is a crucial process that requires attention to detail to ensure the plant’s health and continued growth. Here’s a comprehensive guide on the best time to repot, how to handle backbulbs, and the key steps to follow when dividing and repotting a Cymbidium orchid.
When to Repot
Best Time
The best time to repot a Cymbidium orchid is in the spring, after the plant has finished flowering and new growth is visible. This allows the plant to recover quickly and minimizes stress.
Frequency
Cymbidium orchids should be repotted every 2-3 years, as the roots become too dense and the potting mix breaks down over time.
Preparation
Tools
To repot a Cymbidium orchid, you’ll need the following tools:
– Pruning scissors
– A pot of the appropriate size
– Orchid Focus Repotting Mix or a similar mix with good drainage
Hygiene
Before repotting, it’s important to sterilize your tools and wash your hands thoroughly to prevent the transmission of viruses or diseases.
Repotting Steps
- Remove the Plant: Carefully take the orchid out of its pot and gently remove the old bark or potting mix from the roots.
- Inspect and Trim Roots: Examine the roots and cut away any damaged or dead roots to prevent rot and encourage healthy growth.
- Remove Old Pseudobulbs: Discard any leafless or yellowed pseudobulbs, as they can harbor rot and reduce the plant’s overall health.
- Choose a New Pot: Select a pot that is large enough to accommodate 2 years of growth and has good drainage.
- Add New Potting Mix: Place a layer of bark at the bottom of the new pot, then gently position the orchid so that the base of new growth is below the rim and the older pseudobulbs are against one side. Fill the pot with the new potting mix, tapping it down to avoid gaps.
- Water and Establish: Water the plant the day before repotting to make it easier to handle. After repotting, water sparingly until the plant is established in its new pot.
Additional Tips
Divide and Repot
If the Cymbidium orchid has become too large, divide it into smaller groups of 3-4 bulbs. Smaller divisions may not flower the first year, but they will establish more quickly.
Potting Mix
Use a potting mix with good drainage, such as a 50% pine bark and 50% coir peat mix. The specific mix may vary depending on your climate and watering regime.
Fertilization
Avoid fertilizing the Cymbidium orchid for about 2 months after repotting to allow the plant to settle and recover.
By following these steps and considering the specific needs of your Cymbidium orchid, you can ensure a successful repotting process that promotes healthy growth and beautiful blooms.
