How to Grow and Care for Grammatophyllum martae
Hardiness: USDA hardiness zone 10a to 11b: from 30°F (-1.1°C) to 50°F (10°C).
Grammatophyllums grow well in moderate light intensity. Morning sun is best until about noon. Observing leaf structure can be your best guide to the light conditions a type is best suited to. Lime green foliage indicates proper light. While very attractive, dark green foliage does not help the plant reach its full blooming potential. Yellow-colored foliage indicates too much light. In very mild climates, most members of this genus can be grown outdoors, with protection from the hot summer sun and winter colder nights.
The ideal annual temperature range for most members of the genus Grammatophyllum is 75°F to 85°F (24°C to 30°C) during the day and 55°F to 60°F (13°C to 16°C) at night. Plants will tolerate temperatures up to 45°F (10°C) and up to 100°F (38°C) for short periods. At higher temperatures, increase air circulation and humidity, or damage can occur.
