What Soil Mix Works Best for a Myristica macrantha?
Rich, well-draining soil with high organic content. Good drainage is essential for Myristica macrantha to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Myristica macrantha?
Feed Myristica macrantha every 6 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.

Where Should You Plant a Myristica macrantha?
Choose a spot with partial shade to full sun and rich, well-draining soil with high organic content. Avoid low spots where water collects after rain.
Myristica macrantha is suited to USDA Zone 11b – 12b.
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 Myristica macrantha?
Myristica macrantha can spread to about 15 ft (4.6 m) and reach about 30 ft (9 m) tall. Space plants about 15 ft (4.6 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 Myristica macrantha?
Prune Myristica macrantha 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.

Myristica macrantha can be propagated through seeds. Similar propagation techniques also apply to wild nutmeg plant care, which shares the same genus.
