Basics of Cymbidium Orchid Care
Basic care of Cymbidium Orchids involves, dividing, identifying diseases, and fertilising. Understand the growing guide and care instructions for Cymbidium orchids and you will produce magnificent flowers.
One of the most popular orchids to grow and Cymbidium orchids are readily available for sale.
The pot of cymbidiums (pictured right), is a classic example of a neglected pot of of orchids, overcrowded and in need of division and a care to bring them back to their best, we tell you how.
Care and repotting
Origins of Cymbidium Orchids
Cymbidium Orchids are originally from the Himalayas, over the years they have been hybridised to produce the beautiful cymbidium orchids with long lasting flowers that we love so much.
Cymbidium Orchids need a cool winter temperatures to flower. Cymbidium Orchids do not flower well in warmer climates. Cymbidiums are widely used in corsages and as cut flowers. Their are two main types of cymbidium orchids, standard cymbidiums and miniature cymbidiums.
So basic care involves fertiliser, dividing watering and of course repotting.
Asked if you really do need to re-pot Cymbidium Orchids, te answer is yes. They do have extensive root systems and although you can feed them and they will flower eventually you will run into two problems.
The first is overcrowding, the plant creates to many back bulbs and pseudo bulbs and becomes tired.
Secondly the root system demands it, pictured right is a pot of Cymbidium Orchids that were left a little to long before dividing and repotting, the roots actually split the terracotta pot apart.
So as with any plant,proper regular care is essential. At the same time we have seem these hardy orchids growing in the ground beside a garden shed, doing very well with little care at all.
Repotting or dividing Cymbidium Orchids.
- Divide and repot Cymbidiums every second to third year, in the spring after flowering has completed.
Cymbidium Orchids will need repotting
- Remember that cymbidiums produce three types of bulbs:
‘back bulbs’ those without foliage are there to store food
‘old bulbs’ bulbs with leaves that may produce flowers
‘lead bulbs’ these are the new bulbs that produce vigorous growth and large flower spikes.
- When dividing cymbidiums aim to have a lead bulb and one or two ‘back bulbs’, the back bulbs provide the energy needed for a new division of cymbidiums to thrive.
- After dividing remove any dead roots and leave the newly divided cymbidiums to harden for a day or two in a cool place.
- Repot cymbidiums in an orchid or specialist cymbidium potting mix
Cymbidium Orchids are easy to grow, basic instructions:
- Use a specialist Orchid potting mix (free draining)
- Plant the bulb with 1/2 above the surface
- Filtered light is best
- Water regularly
- Divide cymbidium orchids when over crowded
- Fertilise in mid winter to spring
- Avoid frost
Growing conditions for Cymbidium Orchids.
Cymbidiums, are from the Himalayas where night temperature is low. With this in mind we can understand that cymbidium orchids require some protection from extreeme heat and an overnight drop in temperature to help produce flower spikes. One technique used is to water early cymbidiums in the morning, this helps produce the drop in soil temperature required to promote flowering.
Cymbidium Orchids prefer bright but indirect light, if the foliage is dark green, chances are your cymbidiums do not have enough light. A healthy cymbidium will have light green foliage with just a touch of yellowing. Try a sheltered position in a shade house, or under the eaves of your house.
Fertiliser and potting mix
A properly formulated cymbidium orchid potting mix is recommended. Fertilise cymbidium orchids as soon as flower spikes appear, we suggest a specialist orchid fertiliser. If you use a slow release fertiliser try every six months, if you use a liquid fertiliser try a diluted (half strength) solution more frequently, every 2 weeks.
Cymbidiums do require regular watering, but don’t like to be water logged. If you are using the right potting mix, water once a week in most conditions, however in hot and drying times water more frequently.
Other than this cymbidiums require little special care and attention.
Yes you can bring Cymbidiums indoors for a while when in flower. Actually growing them indoors is not generally ideal. These are an orchid that require cool nightie temperatures otherwise flowering is poor.
You could try a position near a window where the plant gets good light but not direct sunlight. However many growers simply bring them inside when they are in flower, and them for only 5 – 6 days at a time before resting them
Cymbidiums love lots of feeding, we prefer the liquid fertiliser, once every 2 weeks over summer and regular watering once a week, to help produce the flower spikes that cymbidium orchids are loved for.
