About Pedalai

Artocarpus sericicarpus · also called Pedalai, Hairy-fruited Breadfruit · tropical

Pedalai is a rare Bornean Artocarpus species producing large, hairy-skinned fruits with sweet, yellow-orange arils surrounding seeds, eaten fresh or cooked across Borneo and the Philippines. Less well-known than breadfruit or jackfruit, it is a collector's tree grown by tropical fruit enthusiasts. It requires a consistently hot, humid, lowland tropical climate and deep, fertile, well-drained soil.

Mature size: 10–20 m tall (33–65 ft) in native habitat; typically 5–8 m in cultivation

How to tell pedalai needs repotting

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

Thick roots out of the drainage holes, or circling the surface and lifting the plant.
The pot dries out unusually fast and pedalai wilts between waterings it used to shrug off.
The plant is visibly top-heavy and tips over easily.
Stalled growth and small new leaves over a full season — though with a big specimen, top-dressing is often the better first response before a full repot.

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 pedalai

Every 2–3 years; top-dress in the in-between years. Pedalai's growth habit — medium to large evergreen tree with broad, glossy leaves and a dense canopy — sets the pace. Pedalai is a rare Bornean Artocarpus species producing large, hairy-skinned fruits with sweet, yellow-orange arils surrounding seeds, eaten fresh or cooked across Borneo and the Philippines. Less well-known than breadfruit or jackfruit, it is a collector's tree grown by tropical fruit enthusiasts. It requires a consistently hot, humid, lowland tropical climate and deep, fertile, well-drained soil.

What size pot to step pedalai up to

Move up exactly one pot size. A heavy pedalai dropped into a vastly bigger pot sits in a reservoir of wet soil its roots cannot reach, which rots them and destabilises the plant. In the years between repots, lift off and replace the top 3–5 cm of soil (top-dressing) instead — it refreshes nutrients without the shock of a full repot.

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 pedalai

Early spring, just as new growth restarts, is the ideal window for pedalai. The plant is moving into its strongest growth phase and re-roots into fresh soil quickly. Avoid repotting in winter dormancy or, for flowering plants, while it is in bud or bloom — recovery is slowest then and you risk dropping the flowers.

Step-by-step: repotting pedalai

Consider top-dressing first. If pedalai is not badly root-bound, scrape off and replace the top 3–5 cm of soil instead — far less shock for a big plant that hates moving.
Get help and one size up. For a full repot, choose a pot just one size larger. A heavy plant needs two people and a stable, free-draining pot.
Ease it out on its side. Lay the plant down, slide the pot off, and gently loosen the outer roots. Do not bare-root a mature specimen.
Repot at the same depth. Add fresh deep, rich, well-drained tropical loam or clay-loam with high organic matter (ph 5.5–6.5). beneath and around the rootball, keeping the original soil line. Firm it so the trunk is stable and upright.
Water and leave it put. Water thoroughly, then leave pedalai in the same spot and light — moving and repotting at once is what makes it drop leaves.

Aftercare

Leave pedalai in exactly the same spot and light it was in before — moving and repotting at the same time is what makes a big specimen drop leaves. Water it in well, then let the top of the soil dry before watering again so the larger volume of fresh soil does not stay sodden. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for pedalai

Pedalai wants deep, rich, well-drained tropical loam or clay-loam with high organic matter (ph 5.5–6.5).. Native to the deep, humus-rich, lateritic soils of Bornean lowland rainforest. Amend planting sites extensively with compost and well-rotted manure. Good drainage is critical despite the high moisture requirement — the tree needs moist soil, not standing water. Raised planting mounds help in low-lying sites. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting pedalai — frequently asked questions

How often should you repot pedalai?

Every 2–3 years; top-dress in the in-between years for pedalai. Fully repot pedalai only every 2–3 years; in the in-between years just top-dress the top 3–5 cm of soil. Step up one pot size in spring with deep, rich, well-drained tropical loam or clay-loam with high organic matter (ph 5.5–6.5).. It is heavy and hates being moved, and a vastly oversized pot holds water against the roots and rots them.

What size pot does pedalai need?

When is the best time of year to repot pedalai?

Should you top-dress or fully repot pedalai?

For a big, heavy pedalai, top-dressing — replacing the top 3–5 cm of soil — is the gentler option most years, with a full repot only every 2–3 years. A mature specimen sulks and drops leaves when fully repotted, so do it as rarely as the roots allow.

Should you fertilise pedalai after repotting?

Not immediately. Wait about 4 weeks after repotting pedalai. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
