Mounted Orchid

Orchidaceae (various genera)

flower

Mounted orchids are epiphytic orchids grown on tree bark, cork, or driftwood mounts rather than in traditional pots, mimicking their natural rainforest habitat. This growing method allows for excellent air circulation around the roots and creates a dramatic, decorative display. Common mounted varieties include Phalaenopsis, Dendrobium, and Cattleya orchids.

Vegetative Growth

Several months

New shoots and leaves emerge; aerial roots develop and attach to mount

Maintain consistent moisture through misting; provide bright indirect light; fertilize biweekly with diluted orchid fertilizer

3

Maturation

3-6 months

Plant fills out with multiple stems and well-developed root system; pseudobulbs form on some varieties

Continue regular misting and fertilizing; provide slight cooling period (10°F reduction) to trigger blooming
