Boat Orchid (Cymbidium Orchid) Description

Boat Orchids are popular easy to grow indoor orchids that bear large waxy flowers arranged on an unbranched flowering stem which last for weeks.

The lip (lowermost petal) in Boat Orchids is significantly different from the other petals and sepals and has three lobes and a spotted center. The shape of the lip gives this orchids their common name, 'Boat Orchids'.

Boat Orchids are prolific bloomers; with several flower spikes bearing up to 100 blooms per season.

Some species of Boat Orchids have thin stems but in most species the stems are modified to pseudobulbs.

Where leaves in Boat Orchids are present, there are 3-12 light-green leaves arranged in two ranks and they last for several years.

The genus name Cymbidium is derived from the Latin name Cymba meaning "cup", "bowl" or "boat" in reference to the shape of the lip (lowest lower petal).

How to Water Boat Orchid

Boat Orchids are more tolerant of dry soil conditions due to the presence of pseudobulbs and their thick leaves.

As such take care not to overwater your Boat Orchid as it may begin to rot. Read more on how to water houseplants.


Temperature for Boat Orchid

The best temperatures for growing Boat Orchid indoors are between 10-290C.

Warmer days and cooler night temperatures with a difference of 10-150C are ideal for Boat Orchid. The cool nights are essential to trigger flowering.

Ensure there is good air circulation as your Boat Orchid cannot tolerate hot and stuffy conditions.

Humidity for Boat Orchid

Moderate humidity is ideal for Boat Orchids. Where the air is too dry, set the pot on a wet pebble tray to raise humidity for your Boat Orchid.

Withhold feeding for your Boat Orchid during the cold season as growth is minimal at this time. Do not feed an orchid that is in flower.

It is better to err on the side of underfeeding than overfeeding your Boat Orchid.

Overfeeding your Boat Orchid may result in loss of roots thus death of the orchid.

If you overfeed your Boat Orchid, it can also lead to vegetative growth instead of flower production. Read more on how to feed houseplants.

How to Repot Boat Orchid

Boat Orchids bloom best when they are pot-bound. Repot Boat Orchid only when growth begins to suffer.

Repot Boat Orchid when the orchid has outgrown its pot and the new growth reaches out over the edge of the pot or when the soil has broken down completely.

Basically repotting your Boat Orchid every 2-3 years should be adequate.

Repot your Boat Orchid only when new growth begins, shortly after blooming is over.

Use a pot with proper drainage holes or slits as the roots of your Boat Orchid need good air circulation.

The pot for your Boat Orchid should be only 1 size larger than the previous one.

Use loose, free-draining bark soil for your Boat Orchid.

When repotting your Boat Orchid, shake off excess soil and trim off any dried and shrivelled pseudobulbs.

The large Boat Orchids can be divided to propagate new plants.

How to Prune Boat Orchid

Pruning Boat Orchid is easy. Remove dead and diseased leaves by cutting them at the base with sharp scissors or a knife.

When flowering is over for your Boat Orchid, cut the flower stalk 1 in. above the 3rd node from the bottom.

How to Trigger Flowering in Boat Orchid (Cymbidium Orchid)

Give Boat Orchid 6 weeks of cool temperature of about 7-100C during the cold season.

Reduce watering for your Boat Orchid but maintain the soil moderately moist during this period.

Boat Orchid (Cymbidium Orchid) Propagation

Boat Orchids can be propagated at the beginning of the growing season once flowering is over from the pseudobulbs.

Gently split the Boat Orchid pseudobulb into sections and ensure there are at least 3 shoots on each section.

Seperate the roots attached to each Boat Orchid division from the mother root-ball.

Remove the old potting soil attached to the roots of the Boat Orchid sections.

Place each Boat Orchid section in the center of the pot.

Bury the roots of the Boat Orchid section in the soil while ensuring that the bottom of the pseudobulb is level with the top of the soil.

The best pot should be about 1-2 in. larger than the pseudobulb of the Boat Orchid section.

Ensure the pot has enough drainage holes and slits to prevent root-rot of the Boat Orchid section.

Place the set up in a shaded place until the Boat Orchid sections have established their own roots.

Water the new Boat Orchids lightly to enhance root development. Stake each newly repotted plant.
