What Soil Mix Works Best for a Philippine Rafflesia?

Rich, loamy soil with high organic content. Good drainage is essential for Philippine Rafflesia to prevent waterlogging, which leads to root rot and fungal issues.

Where Should You Plant a Philippine Rafflesia?

Choose a spot with partial shade and rich, loamy soil with high organic content. Avoid low spots where water collects after rain.

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.

How Far Apart Should You Plant a Philippine Rafflesia?

Philippine Rafflesia 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.

How Do You Prune a Philippine Rafflesia?

Prune Philippine Rafflesia 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.
