Signs to Identify When an Orchid Needs Repotting
Orchids, one of the largest families of flowering plants, can thrive with proper care, and repotting is an essential aspect of that care. Here's a comprehensive guide on when to repot your orchid and how to do it for optimal health.
When to Repot
The best time to repot an orchid is just after it has finished blooming, when the flowers have died off. This is to prevent any risk of losing the blooms. Signs that your orchid may be ready for repotting include:
- White roots growing out of the drainage holes, indicating the plant has outgrown its pot.
- Potting medium breaking down or becoming compacted, which reduces drainage and aeration needed for healthy roots.
- Tightly tangled or root-bound roots, restricting growth and nutrient uptake.
- New root tips emerging, indicating active growth and possibly a need for more space or fresh medium.
- Orchid outgrowing its current pot, such that the roots have little room to expand.
How to Repot
- Choose a container that is 1-2 inches larger than the previous pot. Clear plastic pots with drainage holes are recommended for inspecting orchid roots.
- Prune the old flower stem at the bottom node before repotting. Remove any stakes and clips as well.
- Inspect the roots after shaking off the old media. Cut out any diseased, soft, or discolored roots. Orchid roots should be evenly colored and firm.
- When repotting, it's important to remove dead or diseased roots and prune the plant as needed. The medium should not be too fine, as it can lead to root rot and other fungal diseases.
- Most purchased orchid mixes are made of bark, sphagnum moss, tree fern, and lava rock. The best orchid potting medium may vary depending on the species, with some requiring more absorbent materials and others a drier bark mix.
- Fill the new pot with the chosen potting medium, leaving enough space for the roots. Gently place the orchid into the pot, ensuring the roots are spread out evenly. Fill in the gaps around the roots with more potting medium.
- Water the repotted orchid thoroughly, allowing any excess water to drain away. Some orchid experts recommend sprinkling cinnamon on the roots after trimming to prevent fungal diseases.
Repotting Frequency
Orchids generally benefit from repotting about once a year or every two years to refresh the medium and maintain good root health, even if they aren't root-bound yet.
