Gomesa radicans (Rchb.f.) M.W.Chase & N.H.Williams

Gomesa radicans is a miniature orchid from Brazil, previously known in many collections as Oncidium radicans. It grows as a creeping plant, with small pseudobulbs and firm leaves, and a mature plant gradually forms a compact clump from which pleasantly fragrant yellow flowers emerge. It is a species that does not impress with its size, but with the density of a well-established specimen.

Light and the right location. Provide medium, filtered light, near an east-facing window or some distance from a very bright window. Strong direct sun can leave spots on the leaves, while insufficient light slows growth and reduces flowering. Intermediate to warm temperatures are suitable, and gentle air circulation helps limit problems when the air becomes humid.

Watering and humidity. The fine roots prefer a lightly moist substrate, not a pot full of water. Water when the growing medium is nearly dry, then allow the excess to drain away. Do not leave the plant completely dry for many days in a row, especially during the growing season. Moderate humidity is beneficial, but it cannot compensate for poor drainage.

Fertilizing and growth. During the active growing season, apply diluted orchid fertilizer after watering. Do not try to encourage rapid growth with large doses: small roots are more sensitive to salt buildup. New leaves and pseudobulbs that gradually become rounded indicate that the plant is growing well.

Potting, mounting, and repotting. A small pot, an airy basket, or a stable mount is more suitable than a large container. The plant needs room to spread laterally rather than being planted unnecessarily deeply. Repot when new roots appear, using a fine, airy mix; you can adapt the substrate for vigorously growing orchids with finer bark and a little sphagnum.

Flowering and signs to watch for. The flowers appear more impressively on a mature, well-lit clump. Wrinkled pseudobulbs indicate thirst or compromised roots; soft bases indicate stagnant water. Avoid dividing the plant frequently: leaving several new growths together helps build a plant that will flower more successfully the following season.
