About African Bush Mango

Irvingia gabonensis · also called African bush mango, dika nut · edible

African bush mango is a tropical West African canopy tree grown for its mango-like fruit and prized oil-rich dika nut, ground into 'ogbono' for thickening soups. It demands constant warmth, deep fertile soil and high humidity, fruiting only in true tropical or large heated-glasshouse conditions. It is frost-tender and slow to bear, typically 4 to 6 years from seed.

Mature size: 15-40 m in habitat; restricted to a few metres in a large container under glass.

Watch for — Slow to fruit: Seed-grown trees take roughly 4-6 years (sometimes far longer in pots) to bear, testing grower patience.

How to tell african bush mango needs repotting

Repotting on a calendar is less reliable than reading the plant. For african bush mango, watch for these signs:

Roots circling the bottom of the module or pot, or poking out of the drainage holes.
The seedling dries out within a day and growth has visibly stalled.
Roots are white and matted in a tight spiral when you tip the plant out.
It has outgrown its current container for the stage of the season — pot african bush mango on before it becomes hard root-bound.

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot african bush mango

Pot on seedlings as they grow; not a perennial repot. African Bush Mangois grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. Evergreen tree with a dense, rounded crown, fruiting on mature wood..

What size pot to step african bush mango up to

Pot african bush mango on gradually — a seedling jumped straight into a huge pot sits in cold, wet, airless soil and stalls. Step up one or two sizes at a time as the roots fill each container, finishing in a large final pot or the ground. The aim is roots that never circle and never check.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot african bush mango

Pot african bush mango on through the active growing season, whenever roots fill the current container — there is no single date, just "before it becomes root-bound". Avoid potting on during a cold snap.

Step-by-step: repotting african bush mango

Pot on before it is root-bound. Check african bush mango regularly; move it up as soon as roots reach the edge of the cell or pot, not after they have circled.
Step up one or two sizes. Choose the next container up — not a giant one. Cold, wet, unused soil around a small root system stalls seedlings.
Knock it out gently. Support the stem, tip the pot, and ease the rootball out without breaking it. A little teasing of circled roots at the base is fine.
Pot into rich mix. Set it into fresh deep, fertile, free-draining loam at the same depth (tomatoes are the exception — they can go deeper to root along the stem).
Water in and grow on. Water well, keep it in good light, and resume feeding once it is established and growing again.

Aftercare

Water african bush mango in well and keep it in bright light; a freshly potted-on seedling can wilt for a day while roots settle, so do not overcompensate by drowning it. Do not fertilise for about 1 week — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for african bush mango

African Bush Mango wants deep, fertile, free-draining loam. Prefers rich loams or fertile sandy soils, pH 5.5-7. Add organic matter for moisture retention but ensure drainage; it will not tolerate compacted or waterlogged ground. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting african bush mango — frequently asked questions

How often should you repot african bush mango?

Pot on seedlings as they grow; not a perennial repot for african bush mango. African Bush Mango is a seasonal crop, so you pot it on as a growing plant rather than repotting a perennial. Step seedlings up gradually into deep, fertile, free-draining loam so the roots never circle the cell, ending in a large final container. A root-bound transplant stalls and never fully recovers.

What size pot does african bush mango need?

When is the best time of year to repot african bush mango?

Can you put african bush mango straight into a much bigger pot?

No. Even a fast-growing african bush mango should only go up one pot size at a time. A vastly oversized pot holds a reservoir of wet soil the roots cannot reach, which stays cold and soggy and rots the roots — the opposite of what you wanted.

Should you fertilise african bush mango after repotting?

Not immediately. Wait about 1 week after repotting african bush mango. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
