Grammatophyllum Orchid – Pakkret Leo 'Sabre' - Assam Orchids

🌺 Introducing the Grammatophyllum Orchid

Make a bold statement in your collection with the Grammatophyllum Orchid, sourced from Assam Orchids. Known for producing some of the largest orchid specimens in the world, Grammatophyllum orchids feature robust pseudobulbs and long arching sprays of strikingly patterned flowers. They are low-maintenance, resilient giants that add drama and tropical splendor.

💚 Care Instructions

Grammatophyllum orchids are known for being relatively low-maintenance, thriving under specific conditions to ensure robust growth and prolific blooming. Follow these guidelines for a healthy plant:

• Temperature: Maintain daytime temperatures between 22°C to 30°C (72°F to 85°F). Nighttime temperatures should ideally drop to 18°C to 24°C (65°F to 75°F) to encourage flowering.
• Humidity: Aim for 50% to 70% humidity. Ensure good air circulation to prevent fungal issues.
• Fertilizer: During the active growing season (spring through early fall), feed consistently with a balanced NPK (20-20-20 or 15-15-15) fertilizer at half the recommended strength. To encourage blooming, a high-phosphorus fertilizer (e.g., 0-52-34) can be used after a brief dry period. Flush monthly with clear water to prevent salt buildup.
• Repotting: Repot every 1-2 years, ideally in the spring, when the medium begins to break down.

☀️ Light & Water Needs

• Light: Provide bright, filtered light, similar to what Cattleya or Dendrobium orchids prefer. Morning sun is beneficial, but protect the plant from harsh midday sun to prevent leaf scorch. Healthy leaves typically exhibit a vibrant lime-green color.
• Watering: During the active growing season (spring through early fall), water frequently and heavily, allowing the potting mix to nearly dry out between waterings. Reduce watering frequency significantly during the cooler winter months. The large pseudobulbs serve as water storage and should remain plump.

📏 Size & Dimensions

• Potting & Media: Use a coarse, well-draining orchid mix comprising materials such as bark, charcoal, and sphagnum moss. These orchids prefer to be slightly pot-bound. Due to their extensive root systems and mature size, large specimens are often best grown in wire or wooden baskets.
• Plant Size: Mature plant with large pseudobulbs, suitable for growth in spacious containers or hanging baskets.

🌍 Origin

Grammatophyllum orchids are typically native to tropical and subtropical regions of Southeast Asia, thriving in the warm, humid conditions of forest canopies.

Q: What is the best way to water my Grammatophyllum orchid?
A: During the active growing season, water frequently and heavily, letting the potting mix almost dry out between waterings. In winter, reduce watering. The pseudobulbs should stay plump.

Q: How often should I fertilize my Grammatophyllum orchid?
A: During the growing season, feed consistently with a balanced NPK fertilizer at half strength. You can use a high-phosphorus fertilizer to encourage blooming after a dry period. Flush with clear water monthly.
