Companion Mounted Orchids

Orchidaceae spp. (mounted on cork or bark)

flower

Mounted orchids are epiphytic orchid specimens attached to cork bark, driftwood, or tree fern slabs to mimic their natural rainforest habitat. This mounting method allows for excellent air circulation and drainage while creating dramatic, naturalistic displays. Multiple compatible orchid species can be grown together on the same mount for a stunning composition.

Growth Stages

1

Attachment & Establishment

2-4 weeks

Fresh mounting with orchid secured to cork/bark; roots begin to grip and aerial roots develop

Keep mounting medium consistently moist; mist multiple times daily; avoid moving the mount; use soft ties that won't girdle stems

2

Root Development

4-8 weeks

Aerial roots elongate and firmly anchor to mounting medium; new root tips appear white and tender

Maintain high humidity (60-80%); provide bright light to encourage photosynthesis; avoid disturbing developing roots

3

Vegetative Growth

Several months to 1+ year

New leaves and pseudobulbs develop; plant becomes established with sturdy root system

Water and mist regularly; apply diluted orchid fertilizer weekly during growing season; ensure excellent air circulation

4

Pre-Flowering

2-4 weeks

Flower spikes emerge; plants show vigor with healthy foliage and mature pseudobulbs

Slightly reduce watering to trigger blooming; provide cooler nighttime temperatures (10°F drop); maintain bright light

5

Blooming & Maintenance

4-12 weeks per bloom cycle

Flowers open and display; blooms last weeks to months depending on species

Resume regular watering; avoid moving blooming plants; mist around (not on) flowers; remove spent flowers to encourage reblooming
