About Restrepo's Chigua

Chigua restrepoi · also called Restrepo's Chigua, Chigua · tropical

Chigua restrepoi is a critically endangered Colombian cycad from wet tropical forests of the Chocó and Antioquia regions. It produces a small trunk or largely subterranean caudex and bright green pinnate fronds adapted to deep shade. One of the rarest cycads on Earth, it demands warm, humid, shaded conditions. All parts are severely toxic to pets and humans.

Mature size: 0.5–1.5 m tall, 1–2 m spread

Watch for — Root disturbance sensitivity: Chigua restrepoi is sensitive to repotting and root disturbance. Repot only when rootbound, in late spring or early summer, into a container only marginally larger than the previous one. Handle roots gently and water minimally for several weeks post-repot.

How to tell restrepo's chigua needs repotting

Repotting on a calendar is less reliable than reading the plant. For restrepo's chigua, 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 restrepo's chigua 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 restrepo's chigua

Every 2–3 years; top-dress in the in-between years. Restrepo's Chigua's growth habit — short or subterranean trunk, rosette of arching, glossy pinnate fronds; forest understorey habit — sets the pace.

What size pot to step restrepo's chigua up to

Move up exactly one pot size. A heavy restrepo's chigua 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 restrepo's chigua

Early spring, just as new growth restarts, is the ideal window for restrepo's chigua. 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 restrepo's chigua

Consider top-dressing first. If restrepo's chigua 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 rich, moist, free-draining forest loam 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 restrepo's chigua in the same spot and light — moving and repotting at once is what makes it drop leaves.

Aftercare

Leave restrepo's chigua 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 restrepo's chigua

Restrepo's Chigua wants rich, moist, free-draining forest loam. Mimick tropical forest floor conditions: a mix of loam, composted bark fines, coco coir, and coarse perlite in roughly equal parts. Should retain some moisture while allowing excess water to drain freely. Slightly acidic pH (5.5–6.5) preferred. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting restrepo's chigua — frequently asked questions

How often should you repot restrepo's chigua?

Every 2–3 years; top-dress in the in-between years for restrepo's chigua. Fully repot restrepo's chigua 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 rich, moist, free-draining forest loam. It is heavy and hates being moved, and a vastly oversized pot holds water against the roots and rots them.

What size pot does restrepo's chigua need?

When is the best time of year to repot restrepo's chigua?

Should you top-dress or fully repot restrepo's chigua?

For a big, heavy restrepo's chigua, 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 restrepo's chigua after repotting?

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