Cymbidium Orchid /Ground Orchid – Bulb (Mix Colour)

Growing a Cymbidium orchid from a bulb-like structure (called a pseudobulb) is usually done by division rather than from seed. Here’s how to encourage healthy growth.

1. Choose a healthy pseudobulb

• Select a firm, green pseudobulb with at least one healthy growing eye (bud).
• For best results, divide a mature plant so each division has 3–5 pseudobulbs, including at least one with active new growth.

2. Use the right pot

• Choose a pot with excellent drainage.
• Cymbidiums prefer being slightly crowded rather than overpotted.

3. Prepare the potting mix

Use a coarse, well-draining orchid mix such as:

• Medium fir bark or pine bark
• Perlite
• Charcoal
• Coconut chips (optional)

Avoid regular garden soil, which holds too much water.

4. Plant correctly

• Position the pseudobulbs at the surface of the mix.
• Cover only the roots—do not bury the pseudobulbs deeply.
• Place the newest growth facing the center of the pot with room to expand outward.

5. Watering

• Water thoroughly after planting.
• Then allow the top of the mix to become slightly dry before watering again.
• During active growth (spring and summer), water more frequently.
• Reduce watering somewhat in winter, but don’t let the roots dry out completely.

6. Light

• Provide bright, indirect light or gentle morning sun.
• Leaves should be light green. Very dark green leaves often indicate insufficient light.

7. Temperature

Cymbidiums enjoy cooler conditions than many orchids:

• Day: 18–25°C (64–77°F)
• Night: 7–13°C (45–55°F) in late summer and autumn helps trigger flower spikes.

8. Fertilizing

• Feed every 2–4 weeks during active growth with a balanced orchid fertilizer at half strength.
• Flush the pot with plain water once a month to remove fertilizer salts.

9. Repotting

• Repot every 2–3 years, ideally after flowering when new roots begin to grow.

How long does it take?

• New shoots usually appear in a few weeks to a few months, depending on the season.
• A newly divided plant may take 1–2 years to bloom again while it re-establishes.
