What Is the Mountain Cycad?
Mountain Cycad (Encephalartos ghellinckii) belongs to the Zamiaceae family within the Encephalartos genus. Mountain Cycad is native to sub-Saharan Africa. Mountain Cycad is also known as Forest Cycad.
Mountain Cycad displays a slow-growing cycad growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. Mountain Cycad produces cones rather than typical flowers.
Leaf size: approximately 24 inches.
How Often Should You Water a Mountain Cycad?
Water a young or newly planted Mountain Cycad every 14–21 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.
Watering Frequency
Every 14–21 days
Until established; then in dry spells
What Light Does the Mountain Cycad Need?
Mountain Cycad thrives in bright indirect light. Avoid placing Mountain Cycad in direct, harsh sunlight for extended periods, as this can scorch the foliage.
Light Requirement
Bright indirect light
What Temperature and Humidity Does the Mountain Cycad Prefer?
Encephalartos ghellinckii tolerates temperatures of 50–80°F. Mountain Cycad prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Humidity

What Soil Mix Works Best for a Mountain Cycad?
Well-draining sandy soil mix with added organic matter like compost or peat moss. Good drainage is essential for Mountain Cycad to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Mountain Cycad?
Feed Mountain Cycad every 8 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.
Fertilizing
Every 8 months
During the growing season
The PlantoScan app can remind you when to water and when to fertilize each plant.
Where Should You Plant a Mountain Cycad?
Choose a spot with bright indirect light and well-draining sandy soil mix with added organic matter like compost or peat moss. Avoid low spots where water collects after rain.
Mountain Cycad is suited to USDA Zone 8b – 11b.
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.
How Far Apart Should You Plant a Mountain Cycad?
Mountain Cycad can spread to about 4 ft (1.2 m) and reach about 6 ft (2 m) tall. Space plants about 4 ft (1.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

How Do You Prune a Mountain Cycad?
Prune Mountain Cycad 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.
How Do You Care for a Mountain Cycad in Winter?
Mountain Cycad is hardy down to USDA zone 8b, so once established it can stay outdoors through winter in that zone and warmer ones.
Water deeply in late autumn before the ground freezes, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.
Young and container-grown trees need extra protection: roots in a pot freeze much more easily than roots in the ground.
How Do You Propagate a Mountain Cycad?
Mountain Cycad can be propagated through seeds, offsets (pups). Similar propagation techniques also apply to krantz aloe plant care, which shares the same genus.
