Script Grammatophyllum Plant Care

Script Grammatophyllum (Grammatophyllum scriptum) belongs to the Orchidaceae family within the Grammatophyllum genus. Script Grammatophyllum is native to south east Asia. Script Grammatophyllum is also known as Dotted Grammatophyllum.

Script Grammatophyllum displays a large epiphytic orchid growth habit, reaching up to 6 ft tall with a spread of approximately 3 ft. Script Grammatophyllum produces showy, large flowers in yellow, green, brown or red.

Leaf size: approximately 12 inches.

Water a young or newly planted Script Grammatophyllum every 7–10 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established trees mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Script Grammatophyllum thrives in bright indirect light. Avoid placing Script Grammatophyllum in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Grammatophyllum scriptum tolerates temperatures of 60–85°F. Script Grammatophyllum prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining orchid mix with bark and perlite. Good drainage is essential for Script Grammatophyllum to prevent waterlogging, which leads to root rot and fungal issues.

Feed Script Grammatophyllum every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

Choose a spot with bright indirect light and well-draining orchid mix with bark and perlite. Avoid low spots where water collects after rain.

Script Grammatophyllum is suited to USDA Zone 13a.

Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.

Script Grammatophyllum can spread to about 3 ft (0.9 m) and reach about 6 ft (2 m) tall. Space plants about 3 ft (0.9 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Script Grammatophyllum while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the tree in one year.

Script Grammatophyllum is frost-tender (hardy to USDA zone 13). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Script Grammatophyllum can be propagated through division, back bulbs.

Script Grammatophyllum is susceptible to aphids, scale insects, spider mites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Script Grammatophyllum grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Script Grammatophyllum is native to south east Asia. In cooler regions, grow Script Grammatophyllum as a houseplant or bring it indoors before the first frost.
