Appearance

Collabium orchids have thin, elongated stems that can grow up to 60 cm in length. The leaves are leathery, green, and lance-shaped, with a prominent midrib.

Care Guide

Collabium orchids are relatively easy to care for and can thrive in a variety of conditions. Here are some tips for caring for your Collabium orchids:

Water

Collabium orchids prefer to be kept evenly moist, but not soaking wet. Water them once a week, or when the top inch of the potting mix feels dry. Avoid getting water on the leaves, as this can lead to rot.

Fertilization

Feed your Collabium orchids every two weeks during the growing season with a balanced orchid fertilizer. Reduce the frequency to once a month during the dormant season.

Soil

Collabium orchids prefer a well-draining potting mix that is made of bark, perlite, and sphagnum moss. Repot your orchid every two years, or when the potting mix starts to break down.

Sunlight

Collabium orchids prefer bright, indirect light. Avoid placing them in direct sunlight, as this can scorch the leaves.
