Oncidium Gerardo Guachisaca

A floriferous hybrid of Onc. tigroides × Onc. tipuloides, producing branched, horizontal spikes densely set with small, well-spaced flowers. The rounded sepals and petals bear bold, well-defined spots, while the compact lip displays a neat central callus — a striking pattern inherited from both parents.

• Light: Bright indirect light with 40–60% shade cloth; avoid direct sun, which can scorch the foliage.
• Temperature: 55–75°F (13–24°C); an intermediate to cool grower that benefits from a nighttime temperature drop to encourage blooming.
• Humidity: 65–85%; ensure good air circulation to prevent fungal issues at higher humidity levels.
• Watering: Water thoroughly and allow the medium to approach dryness between waterings; never allow roots to sit in standing water.

Additional Notes

Best cultivated in a fine bark or sphagnum moss mix in a well-draining container or mounted on cork. Plants are shipped bare root and well established.
