When repotting orchids, it's crucial to take care of any wounds that may occur on the stems, leaves, or roots. To prevent bacterial infections, apply a fungicide to the affected areas before proceeding. After planting, it’s advisable to mist the plants every two to three days instead of overwatering, ensuring a safer and more controlled environment for recovery.
It's also important to disinfect old pots before reusing them. While it might be tempting to use new containers each time, many orchid growers reuse their pots by thoroughly cleaning them with a disinfectant solution. This not only saves resources but also reduces waste.
Avoid using a pot that is too large for small orchids. A large container can hold excess moisture, leading to poor air circulation and uneven drying after watering. If the planting medium stays wet for too long, it increases the risk of root rot due to bacterial growth.
For blue orchids, such as some species of Dendrobium, it's best to plant them shallowly. Deep planting can cause the roots to remain in a consistently moist environment, which can lead to rot. When planting, make sure the base or pseudobulb is exposed, not buried under the growing medium.
The sprout should be placed in the center of the pot, even if it seems off-center at first. As the orchid grows, the new shoots will naturally develop towards the center, creating a balanced and aesthetically pleasing appearance.
Before placing the orchid in the pot, ensure the roots are evenly spread out and not clumped together. Proper root distribution allows each root to make good contact with the growing medium and promotes better air circulation, reducing the risk of rot.
Orchids should not be planted too deeply, as this can cause instability. To keep the plant upright, use stakes, ties, or hooks to support the stem and prevent it from swaying, which could damage the base or roots.
The planting medium should be slightly compacted, but not overly so. Good drainage and airflow are essential, so gently press the medium from the sides rather than from above to avoid crushing the roots.
After repotting, avoid watering for 3 to 5 days. This gives the plant time to heal and prevents water from sitting on fresh wounds, which could lead to infection. This step is especially important for orchids, as they differ from most other plants in their post-transplant care needs.
Finally, keep newly potted orchids away from direct sunlight. Place them in a warm, shaded area and mist the air to maintain humidity until they show signs of healthy growth. This helps prevent dehydration and supports the plant’s recovery.
