Disa Harveiana

5 seeds

1. Pre-germination preparation

• Disa seeds are extremely fine and need sterile conditions.

• Prepare a moist sphagnum + perlite + sand mix (50:30:20) or orchid seed sowing medium.

• Sterilize the medium with boiling water or steam.

2. Sowing

• Do not cover seeds; they need light to germinate.

• Gently sprinkle seeds onto the moist surface.

• Place in a sealed transparent container or plastic pot with humidity dome.

3. Temperature & humidity (Gulf conditions)

• Keep 18–24°C, avoid heat above 28°C — use AC room or shaded greenhouse.

• Humidity 70–90% is needed.

• Avoid direct sun — use bright filtered light.

4. Watering

• Medium must stay constantly moist, not wet.

• Use distilled or RO water, avoid salts.

• Never allow drying out — seedlings die quickly.

5. Germination time

• 2–6 months, sometimes longer.

• Once seedlings are visible, slowly increase ventilation over weeks.

6. Seedling care

• Transplant carefully once seedlings reach 2–3 cm.

• Grow in cool, moist, bright conditions.

• Best outdoors only in cool winter months; keep indoors during hot summer.
