How to Revive Your Orchid: The Ultimate Guide to Repotting Cymbidiums

Repotting cymbidiums is an essential task for maintaining the health and vigor of these beautiful orchids. Whether you’re a seasoned orchid enthusiast or a novice gardener, this comprehensive guide will provide you with all the knowledge and techniques you need to successfully repot your cymbidiums.

Understanding the Importance of Repotting

Cymbidiums, like all living organisms, require fresh potting mix and nutrients to thrive. Over time, the potting mix breaks down, becomes compacted, and loses its ability to provide adequate support and drainage. Repotting rejuvenates the potting mix, provides essential nutrients, and allows the roots to expand and breathe.

When to Repot Cymbidiums

The ideal time to repot cymbidiums is after they have finished blooming and before new growth begins. This typically occurs in late winter or early spring. However, if you notice any signs of root rot, pests, or disease, repotting should be done immediately.

Materials You’ll Need

• Cymbidium plant
• New orchid potting mix
• Sharp, clean pruning shears or scissors
• New pot with drainage holes
• Potting stick or chopstick
• Watering can or hose

Step-by-Step Repotting Instructions

1. Remove the Cymbidium from the Old Pot

• Gently squeeze the sides of the old pot to loosen the potting mix.
• Turn the pot upside down and tap the rim to release the plant.
• If the plant is stuck, gently use a knife or screwdriver to loosen the potting mix around the edges.

2. Inspect the Roots

• Carefully remove any old potting mix from the roots.
• Inspect the roots for any signs of damage, rot, or pests.
• Trim away any dead or damaged roots using sharp, clean pruning shears.

3. Choose a New Pot

• Choose a new pot that is slightly larger than the old one, with adequate drainage holes.
• Terracotta or plastic pots are suitable for cymbidiums.

4. Prepare the New Potting Mix

• Fill the new pot with fresh orchid potting mix to about one-third of the height.
• Moisten the potting mix slightly to make it easier to work with.

5. Position the Cymbidium in the Pot

• Place the cymbidium in the center of the new pot.
• Spread the roots evenly around the bottom of the pot.

6. Fill the Pot with Potting Mix

• Gradually fill the pot with the remaining potting mix, gently pressing down to remove any air pockets.
• Fill the pot to within about an inch of the rim.

7. Water the Cymbidium

• Water the cymbidium thoroughly until water drains out of the drainage holes.
• Allow the excess water to drain completely.

Post-Repotting Care

• Place the repotted cymbidium in a bright, indirect light location.
• Keep the potting mix evenly moist, but not soggy.
• Fertilize the cymbidium monthly with a balanced orchid fertilizer.

Troubleshooting Common Problems

• Root Rot: If you notice any signs of root rot, such as brown or mushy roots, remove the affected roots and repot the cymbidium in fresh potting mix.
• Pests: Cymbidiums can be susceptible to pests such as aphids, mealybugs, and scale. Treat infestations promptly with an appropriate insecticide.
• Yellowing Leaves: Yellowing leaves can be a sign of overwatering, underwatering, or nutrient deficiency. Adjust your watering schedule and fertilize the cymbidium regularly.
