About Thick Gongora

Gongora grossa · also called Thick Gongora · tropical

Gongora grossa is a robust epiphytic orchid from Colombia and Venezuela, producing pendulous racemes of fleshy, fragrant flowers with distinctively thickened, waxy segments. Like all Gongoras it performs best in a hanging basket to allow its drooping spikes to develop unobstructed. Thrives in intermediate to warm conditions with high humidity.

Mature size: Pseudobulbs 8–12 cm tall; inflorescences 30–50 cm long; overall plant spread 25–40 cm

Watch for — Pseudobulb shrivelling: Shrivelled pseudobulbs indicate either underwatering or root loss (which prevents water uptake even when the medium is moist). Check roots — healthy roots are white-green and firm. If roots have rotted, remove dead material, treat with fungicide, and repot in fresh bark.

How to tell thick gongora needs repotting

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

Roots poking out of the drainage holes or coiling visibly around the inside of the pot.
You are watering far more often than you used to because the rootball dries out within a day or two.
Water runs straight through and out the bottom without soaking in.
Top growth has slowed or new thick gongora leaves are noticeably smaller than older ones despite good light.

How often to repot thick gongora

Every 12–18 months — sooner if roots show fast. Thick Gongora's growth habit — sympodial epiphyte forming dense clumps of ovoid to conical pseudobulbs; pendulous flower racemes hang downward from the base of each new pseudobulb, carrying multiple fleshy blooms. — sets the pace. Gongora grossa is a robust epiphytic orchid from Colombia and Venezuela, producing pendulous racemes of fleshy, fragrant flowers with distinctively thickened, waxy segments. Like all Gongoras it performs best in a hanging basket to allow its drooping spikes to develop unobstructed. Thrives in intermediate to warm conditions with high humidity.

What size pot to step thick gongora up to

Step up one pot size — about 2–3 cm (an inch) wider. Thick Gongora grows fast, so it will fill that space within a season, but jumping several sizes at once still backfires: the unused soil stays soggy and rots even a vigorous root system. One size at a time, every year or so, is the rhythm.

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 thick gongora

Early spring, just as new growth restarts, is the ideal window for thick gongora. 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 thick gongora

Time it for spring. Repot thick gongora in early spring as growth restarts so it re-roots quickly into the fresh soil.
Choose one size up. Pick a pot about 2–3 cm wider with drainage holes. One step only — a much bigger pot stays soggy and rots roots.
Ease the plant out. Water lightly the day before, then tip thick gongora out and gently loosen any roots circling the bottom of the rootball.
Repot at the same depth. Put a layer of fresh coarse epiphytic bark mix in a hanging basket in the new pot, set the plant so its soil line is unchanged, and backfill, firming lightly.
Water and pause feeding. Water once to settle the soil. Hold off fertiliser for about a month — fresh mix already has nutrients and feeding now burns new roots.

Aftercare

Water thick gongora once to settle the soil, then let the surface dry before watering again — fresh mix around the roots stays wetter than the old compacted ball, so the commonest post-repot mistake is overwatering. Keep it out of direct sun for a week or two while roots re-establish. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for thick gongora

Thick Gongora wants coarse epiphytic bark mix in a hanging basket. Medium-grade fir bark, perlite, and horticultural charcoal (4:1:1) in an open-slatted wooden or wire basket lined with sphagnum moss. The open structure ensures rapid drainage and airflow around roots. Replace the medium every 2 years as bark decomposes and compacts. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting thick gongora — frequently asked questions

How often should you repot thick gongora?

Every 12–18 months — sooner if roots show fast for thick gongora. Repot thick gongora roughly every 12–18 months, in early spring as growth restarts. It grows fast and circles its pot quickly, so step up one size (about 2–3 cm wider) into fresh coarse epiphytic bark mix in a hanging basket. Don't jump several sizes — that soggy excess soil is what rots vigorous roots.

What size pot does thick gongora need?

When is the best time of year to repot thick gongora?

Can you put thick gongora straight into a much bigger pot?

No. Even a fast-growing thick gongora 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 thick gongora after repotting?

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