Introducing Orchid Cymbidium

These particularly ornamental orchids are famed for their impressive influence indoors but they also like to spend some of their time outdoors. They are hardy orchids, being easy to grow in most regions of Australia and they generally only require basic attention and care. 

Enjoy stunning winter flowers for up to 3 months each year in shades of white, yellow, peach, burgundy, pink, hazel or even green. 

There are many decorative species and varieties to choose from that can each add their own charm so, you’re bound to find the perfect pick for your home. 

Orchid Cymbidium also known as boat orchids

The Cymbidium genus, also known as boat orchids, consists of about 55 species of evergreen flowering plants in the orchid family, Orchidaceae. There are a further 16 natural hybrids as well as many cultivated varieties from modern breeding, each sporting its own flower colour and uniqueness.

Cymbidium is native to the subtropical and tropical regions of Asia and Australia, where they thrive in moderate climates. They are medium-growing plants, taking about 2 to 3 years to mature before flowering. 

Boat Orchid Growing Habits

In cultivation, they usually grow to 50cm to 100cm tall and 60cm to 80cm wide, depending on which species you choose. They do their best potted in tall containers but they can also be hung in large baskets for a more cascading effect.

The cut flowers will also look fantastic in floral arrangements around the house, adding long-lasting spectacular colour and variation to your vases. 

Foliage can be mildly toxic to pets if ingested so be sure to place your plant accordingly if you’re concerned about your fur baby munching on the leaves.

How to Grow Orchid Cymbidium

As with most orchid species, growing these plants from seed is not recommended as the process requires a heavy investment in time, patience and skill.

Even if you can get it right, seeds can take 2 years or longer to show any signs of growth and it could take a further 8 years before your seedling grows big enough to produce blooms. 

Cymbidium Propagation

Cymbidium Propagation

Luckily, you can easily propagate cymbidium orchid using division as these plants are quite forgiving. Alternatively, young and healthy plants should be readily available at your local nurseries or garden centres.

These nursery plants will take far quicker to flower and they are a lot easier to establish in your desired growing location. 

Propagating Orchid Cymbidium Using Division

  • Larger specimens will always need to be repotted every couple of years so during this time, immediately after flowering, you can propagate a disease-free plant. 
  • Gently lift the orchid from its current container to expose the root system.
  • Using a sharp and clean pair of secateurs or a shovel or spade, cut right through the root mass to divide the plant. (Check out these premium pruning shears for reference).
  • Depending on the size of the plant, you can cut it into 2 to 4 pieces. Be sure to divide the plant so that the smaller sections are a decent size for repotting to ensure good flowering next season. 
  • Each newly divided clump should have at least 3 to 4 bulbs with leaves and a few leafless bulbs as well. 
  • Remove any damaged or dead parts from the clumps, including any dry, thinning roots. 
  • Replant each new clump into fresh orchid potting mix and water in lightly. 
  • After a few weeks, once the newly divided plants have started to settle in the new container, you can add a small amount of fertiliser to encourage new roots. 

Tips on Establishing Nursery Plants

  • Young orchids from a nursery may need a little extra protection as they settle in their new environment at your home.
  • Place new nursery plants in a sheltered position indoors for the first few weeks, away from any strong winds, drafts, harsh light or frost. 
  • Mist them occasionally to help with humidity and prune away any damaged parts. 
  • After about a month, you can move them around as needed to allow them to get the right amount of light and water they need to grow and flourish.

Best Conditions for Growing Cymbidium Orchid 

Growing Orchid Cymbidium

Being winter bloomers, you can plant orchids almost any time of the year. For younger plants, planting in spring or autumn is recommended to avoid the hottest and coldest times of the year.

These hardy orchids are however sensitive to strong winds so be sure to position them accordingly. 

Lighting for Boat Orchids

Lighting is the most crucial factor for orchids. Your plant will thrive in good, filtered light or indirect sun for half of each day. Only in the colder months can you expose it to more full sun to encourage flowering as these plants do enjoy the gentle winter sun.

Too much shade will create attractive darker green foliage but with no flowers. On the other hand, too much sun can quickly bleach the leaves, causing them to yellow and burn. 

Orchids don’t respond well to any direct summer sun. Use your leaves as an indicator to see if the lighting is optimal by aiming for mid to light-green leaves. 

Ideal Soil Conditions

As with most orchids, using a premium orchid potting mix with large chips of bark should be perfect. Orchid mixes ensure excellent drainage so be sure to also always use containers with fast drainage for the best results. These plants don’t enjoy sitting with wet feet.

Orchid Cymbidium Care Guide

Caring for orchids will always be a little intensive but luckily, orchid cymbidium is far less demanding overall. Here are our tips for caring for cymbidium to ensure it thrives and flowers best. 

Orchid Cymbidium Care Guide

Boat Orchid Watering Schedule

Water sparingly in winter as rain should be enough. Water when the soil has been dry for more than a week in general. In the summer months, you should water about 3 times per week and in very hot and dry conditions, daily watering may be needed. 

Fertilising Needs

There are two main growing seasons for orchid cymbidium. For healthy leaf growth in summer, the plant will need lots of nitrogen so feed with a fertiliser high in nitrogen (the N ratio in NPK).

After summer, you can cut back on the nitrogen and feed your plant with more potash (potassium) to encourage more prolific flowering. After flowering, you can feed with some high-quality orchid food once.

In general, a balanced liquid fertiliser applied at half strength can be used for the other periods of the year if your plant needs it. 

Improving Flowering

Orchid cymbidium will need a clear distinguishing difference between day and night to flower best. Try to avoid deeply shaded positions and cold night temperatures.

When flowering, bring your plant indoors for the best results. However, these plants are not suited for permanent indoor positions so, after flowering, your plant will need some indirect light outdoors to refuel its processes.

Be sure to also cut off old flower spikes straight after flowering. 

Is Pruning Needed?

Pruning may not be needed for most periods of the year. Prune lightly as needed only to remove damaged or dead foliage and old flowers in spring to early summer. 

For more pruning tips, see our guide on pruning Australian native plants.

Repotting Boat Orchids

Repotting should not be done too often as these plants do enjoy sitting tightly snug in their pots. They also flower best if not disturbed annually. Your plant will need to be repotted every 3 years or so when the roots become overly compacted.

When repotting, you can divide the plant into large clumps and repot each clump. Alternatively, you can simply repot into the next container size. 

Possible Boat Orchid Pests & Diseases

Few pests and diseases trouble these hardy orchids when they’re grown in good conditions. But in many cases, they can suffer from a few nagging issues. 

orchid cymbidium varieties

Scale Insects/Aphids/Spider Mites/Mealybugs

These smaller sap-sucking insects can be a nuisance, especially for indoor plants. Luckily, they can all be treated quite easily by using neem oil which you can spray into the foliage and on the flowers.

Apply your non-toxic neem oil every couple of weeks to get rid of infestations. Alternatively, you can also use a mixture of soap and water to spray and knock them off the plant.  


These larger pests can be attracted to the scented flowers and foliage. They will chew away at the leaves and stems and in severe cases, they can cause some serious damage.

Luckily, they are far easier to identify. If you see your foliage has been eaten away, these guys are probably the cause, especially overnight outdoors. To get rid of them, you can also apply good eco-neem oil or pest control pellets to deter them. 

Bring your plant indoors overnight while treating to avoid them from coming into further contact with your plant. You can also remove them by hand using gloves and dispose of them elsewhere. 

Orchid Cymbidium Frequently Asked Questions

What month do cymbidium orchids flower in Australia?

The most commonly grown species will bud in winter and flower from May through to August and September. The flowers are long-lasting and each species can produce a different amount of flower spikes. 

What is the best potting mix for cymbidium orchids?

Most orchid enthusiasts will recommend using a mixture of bark, perlite, coconut coir and other loose organic material for these orchids. A commercial orchid mix should be able to serve your plant very well. 

When should I buy cymbidium orchids?

Most nurseries stock these spectacular plants between November and March. 

Why is my cymbidium not blooming?

Excessive shade will quickly cause these orchids to become non-flowering, more dormant versions of themselves. Be sure to move your plant into more filtered light or even full winter sun for half of each day to encourage more blooms next season.
