Puerto Rican Zamia Plant Care

Puerto Rican Zamia (Zamia portoricensis) belongs to the Zamiaceae family within the Zamia genus. Puerto Rican Zamia is native to the Susúa State Forest region of western Puerto Rico.

Puerto Rican Zamia 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. Puerto Rican Zamia produces cone-like structures that are not true flowers.

Leaf size: approximately 24 inches.

Water a young or newly planted Puerto Rican Zamia 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.

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

Zamia portoricensis tolerates temperatures of 65–85°F. Puerto Rican Zamia 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 Puerto Rican Zamia to prevent waterlogging, which leads to root rot and fungal issues.

Feed Puerto Rican Zamia 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.

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.

Puerto Rican Zamia is suited to USDA Zone 13b.

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.

Puerto Rican Zamia 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 Puerto Rican Zamia 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.

Puerto Rican Zamia 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.

Puerto Rican Zamia 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.

Puerto Rican Zamia 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.

Puerto Rican Zamia grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Puerto Rican Zamia is native to the Susúa State Forest region of western Puerto Rico. In cooler regions, grow Puerto Rican Zamia as a houseplant or bring it indoors before the first frost.
