Cardboard plant Plant Care

Cardboard plant (Zamia wallisii) belongs to the Zamiaceae family within the Zamia genus. Cardboard plant is native to Colombia. Cardboard plant is also known as Zamia cardboard palm.

Cardboard plant displays a slow-growing, cycad plant with a palm-like appearance growth habit, reaching up to 3 ft tall with a spread of approximately 3 ft. Cardboard plant produces cone-like structures that are not true flowers.

Leaf size: approximately 24 inches.

Water a young or newly planted Cardboard plant every 14–21 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.

Cardboard plant thrives in bright indirect light to partial shade. Avoid placing Cardboard plant in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Zamia wallisii tolerates temperatures of 65–85°F. Cardboard plant prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, slightly acidic soil with added organic matter like peat moss or compost. Good drainage is essential for Cardboard plant to prevent waterlogging, which leads to root rot and fungal issues.

Feed Cardboard plant every 8 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with bright indirect light to partial shade and well-draining, slightly acidic soil with added organic matter like peat moss or compost. Avoid low spots where water collects after rain.

Cardboard plant is suited to USDA Zone 11a – 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.

Cardboard plant can spread to about 3 ft (0.9 m) and reach about 3 ft (1 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 Cardboard plant 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.

Cardboard plant is frost-tender (hardy to USDA zone 11). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Cardboard plant can be propagated through by division of offsets or from seeds. Similar propagation techniques also apply to pineapple plant plant care, which shares the same genus.

Cardboard plant is susceptible to mealybugs, 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.

Cardboard plant grows outdoors in USDA Zone 11a – 12b. It survives winters down to planting zone 11a. Cardboard plant is native to Colombia. In cooler regions, grow Cardboard plant as a houseplant or bring it indoors before the first frost.
