Silver Queen Aglaonema Plant Care

Silver Queen Aglaonema (Aglaonema modestum) belongs to the Araceae family within the Aglaonema genus. Silver Queen Aglaonema is native to Bangladesh, Thailand, Laos, Vietnam, and southeast and south-central China. Silver Queen Aglaonema is also known as Chinese Evergreen, Aglaonema.

Silver Queen Aglaonema displays an upright, bushy shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Silver Queen Aglaonema produces rarely flowers indoors, inconspicuous blooms resembling peace lilies.

Leaf size: approximately 8 inches.

Water a young or newly planted Silver Queen Aglaonema every 7–14 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Silver Queen Aglaonema thrives in bright indirect to low light. Avoid placing Silver Queen Aglaonema in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Aglaonema modestum tolerates temperatures of 65–85°F. Silver Queen Aglaonema prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, peat-based potting mix with perlite for added aeration. Good drainage is essential for Silver Queen Aglaonema to prevent waterlogging, which leads to root rot and fungal issues.

Feed Silver Queen Aglaonema every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs 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 to low light and well-draining, peat-based potting mix with perlite for added aeration. Avoid low spots where water collects after rain.

Silver Queen Aglaonema is suited to USDA Zone 10b – 12b.

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

Silver Queen Aglaonema can spread to about 2 ft (0.6 m) and reach about 3 ft (1 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Silver Queen Aglaonema 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 shrub in one year.

Silver Queen Aglaonema is frost-tender (hardy to USDA zone 10). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Silver Queen Aglaonema can be propagated through stem cuttings, division of offsets. Similar propagation techniques also apply to chinese evergreen plant care, which shares the same genus.

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

Silver Queen Aglaonema grows outdoors in USDA Zone 10b – 12b. It survives winters down to planting zone 10b. Silver Queen Aglaonema is native to Bangladesh, Thailand, Laos, Vietnam, and southeast and south-central China. In cooler regions, grow Silver Queen Aglaonema as a houseplant or bring it indoors before the first frost.
