Cymbidium Orchids – 10 Essentials for Growing Stunning Cymbidiums

Cymbidium Orchid CareCymbidiums are said to be the exception to the rule when it comes to orchid care. Among the types of orchids, this is one that can grow freely outside the confinement of greenhouses and similar structures. In fact, because it thrives so well outdoors, it has been a favorite garden plant. It is not “choosy” in soil, temperature and humidity requirements.

To be able to grow them successfully, here are 10 essential rules that you need to follow:

Temperature

Cymbidiums are one of the most enduring types of orchids when it comes to temperature. They have been observed growing in temperatures ranging from as low as 18°F to as high as 110°F, for a certain limited period of time. These species of orchids are best grown outdoors because they can survive virtually any temperature change.

During harsh winters these orchids should be transferred inside if you wish to have them live through the season. Although they could stand the extreme cold for a combined total of two weeks, it could still mean death to them if left outside unattended.

If you want to make sure that your cymbidiums will bloom and thrive then leave them alone in a place where the temperature is between 20° to 40°. Although there are certain parts Florida that these plants refuse to bloom because apparently the night air is a little hotter than they would like it. Other than that, cymbidiums are the perfect flowers for places with varying temperature.

Light

Since cymbidiums are mostly the outdoor type of orchids, they require a lot of sunlight. During summer they can be exposed to direct sunlight and still survive. Remember though, anything that is too much can cause death to any plant, as is the case with these orchids.

The perfect setting for cymbidiums is under the shade of a larger tree where the sunlight is filtered by the leaves and the shade. If you cannot find a place like this, anything that can provide sufficient shade for them during the harsh summer is fine. During winter, these plants need sunlight more than ever so whenever you can, find a spot for them where they can sulk in the light for hours at a time.

Soil

Although cymbidiums can grow in almost any kind of soil, these type of orchids seems to thrive best in leafmold. Mix equal parts of leafmold and leafsoil together with a little bit gravel and you have the perfect soil mixture for cymbidiums.

Drainage

An important part and sometimes one of the things that growers forget when cultivating these orchids is the drainage. In their natural habitats, cymbidiums are found to grow in places where there is proper and adequate drainage, so you must recreate this when they are cultivated.

A suggested way to do this is by planting them in raised beds, six to twelve inches above the ground. This will ensure that the excess water will naturally exit the soil. Some orchid growers even place a bedrock at the bottom of their plants then fill it with compost to act as a drainage system.

Bedrock

Aside from providing adequate drainage, placing a bedrock beneath the soil will also help your cymbidiums with moisture management. Bury them under the ground with less than half of the rock showing. This will make sure that during the summer their root systems stay cool and in winter will keep them warm enough by removing excess water.

Fertilizer

When it comes to plant food and these types of orchids, the jury is still out. Most orchid growers who use fertilizers say that feeding cymbidiums do wonders for it. Now the only thing that you must be careful not to do is to let the fertilizer touch its pseudobulbs. This is detrimental because once this happens they will most likely burn and rot.

You can use either liquid fertilizers or ground manure. Just remember not to overdo it. Twice a year for ground manure and every three months for liquid fertilizer will be enough to provide the nutrients they need.

Water

Cymbidiums compared to other types of orchids need less water. Since the majority prefers to grow them outdoors, they are okay with a watering once or twice every month even in the summer. And during winter, you can even forget about watering them because the regular rainfall takes care of that for you.

If you grow them indoors, then you will need to make up for the rainfall that’s not occurring. During spring and summer, keep the potting mix evenly moistened regularly. You can water less in the late summer, and barely at all in the winter – keeping it barely moist (much like when you grow them outside). When you water them, let the water run through to wet the mix thoroughly. Then let it drain completely.

Pots

During winter, where extremely low temperatures are unavoidable, you may want to transfer your cymbidiums into pots. Or if you have chosen to grow them indoors, the task of choosing a container for these types of orchids is equally important.

The perfect pots for cymbidiums are those that can provide proper drainage. Keep them away from shallow pots and fern pans. These containers can easily heat up and can dry the roots. Deep clay pots with a layer of rocks at the bottom are preferable for they are cooler and provide adequate drainage.

Medium

Choosing a medium for cymbidiums is fairly easy. As previously said they practically thrive in any kind of soil. But two favorites are osmunda and leafmold. But if you prefer another soil mixture, it will be okay. The only medium known not to support cymbidiums is gravel, as long as you stay away from that, you are fine.

Repotting

Lastly and maybe one of the most crucial steps to growing healthy cymbidiums is repotting. Because cymbidiums have very delicate root systems they do not respond well to repotting. They are said to suffer shock easily. When repotting, make sure that the roots stay intact or else you would not see them bloom for a year or two. Some growers even wait two to three years before attempting such a task.

No matter where you decide to grow them, inside or outdoors, cymbidiums are very gracious plants when it comes to flowers. So be sure to keep these essentials in mind. And if you are looking for the least needy plants of all the types of orchids, then cymbidiums are the answer for you.

    Very helpful with easy to understand very good

    Thanx…real great, simple to understand/use advice! Being a Nursery Manager (at the Potters Yard Nursery) in Hout Bay, Cape Town, S.Africa, I get a lot of queries from clients who buy Orchids, but do not know how to care for them…and this is especially where yar info is invaluable to me, since I’m still learning about Orchid care. etc…myself!

    • Mary Ann says:

      Thank you so much! Would you like the insert we made for another nursery owner? :-) We’ve actually given it out to a couple of flower shops as well to put with orchids they’ve sold. – Mary Ann

  3. Terry says:

    do you ever cut the leaves on a cybidium? it survived the colder winter we had this year in CA, and it looks good someone suggested cutting the leaves back but I have not seen where to do this in your ten points of growing?
    It sounds like all that we should do is consider repotting the plant

    • Mary Ann says:

      No – cutting the leaves could hurt the plant. I wouldn’t bother the leaves at all. If it needs to be repotted, then yes go ahead and do that. Thanks! – Mary Ann

  4. Henny says:

    Thanks so much. Easy to do.

  5. Barbarann says:

    Will cymbidiums re-bloom? How do I make that happen?

  6. Steven Miles says:

    I have many Cymbid. But I have one that is in a 2 1/2 ft pot. I planted it in there 2 yrs ago. And it hasn`t bloomed. And the other 8 are root bound. If I repot them careful like…will they rebloom? Or should I just wait and see if they bloom. Or should I just repot them and see what happens?

    • Mary Ann says:

      It sounds like it might need a new pot at this point. If you are fulfilling the other care requirements, and it’s been that long, you might need a fresh pot with fresh medium. Here’s a post we did on repotting your orchid. Thanks! – Mary Ann

  7. Janet says:

    I am seeing new leaf shoots on my cymbidium,I have never had a bloom on this plant, do flower stalks usually follow leaves? It has recently been
    re-potted.

    • Mary Ann says:

      Is it getting enough light? Sometimes if you are getting new growth with no blooms, the plant just needs more light. So go through the article and make sure you’re meeting all the requirements it needs. We actually just released a book on cymbidium orchid care that can help you. Thanks! – Mary Ann

  8. Barbara says:

    I HAVE A FLORIST ,, CAN I GET THE INFO. ON BUYING ORCDIDS?

  9. twinkle says:

    i have recently acquired a cymbidium orchid plant. it had given a new root that broke accidentally. what happens now?

    • Mary Ann says:

      Keep caring for it. You can cut the root with a sterile tool and then wet it and dust some cinnamon on it to prevent it from rotting. If it’s only one root, it will probably be fine. :-) – Mary Ann

  10. Karianne says:

    Hi! Thanks for the easy summary of care. I purchased two Cymbidiums at our arboretum sale yesterday and need to know how to care for them. I live in central coastal CA, so I see these growing in gardens – thriving and huge! That’s what I want!! They are blooming now and I want to put them in nicer containers than the plastic pots. Should I wait until they stop blooming? How careful do I need to be with the roots? Are they super delicate? Will they bloom every year? Finally, what do you mean by bedrock? Thanks!!

    • Mary Ann says:

      Yes – wait until they stop blooming. Blooming takes a lot of energy, and a disruption in their environment isn’t good for them at that time. Cymbidiums usually have pretty dense roots. Don’t go tearing at them obviously, but you should be able to repot with no problem. They should bloom once a year. A bedrock would be a solid rock that goes under the looser soil. That would be used outside. You can learn even more about cymbidiums here: Cymbidium Orchids – Mary Ann

    a very helpful information for the one who like orchids.

  12. Hirendra Goutam says:

    Thanks for giving all the information regarding care and how to grow cymbadium in a very simple and easy way

  13. louise says:

    I need to repot quit large plants that have a lot of dead in the center. Can you tell me what to do?

  14. wendy says:

    thank you this was very helpful I live in Australis NDW my orchids are outside some foinh well some not thank.you again

    • Mary Ann says:

      Thank you! :-) I’m glad this was helpful to you. I answered your other comment about the ones not doing so well. – Mary Ann

  15. wendy says:

    Thank you I live in Australia my cybs are not doing so well they are outside and we have had a very wet season any ideas ?

    • Mary Ann says:

      It’s hard to tell you what to do with just this information. I’m not sure if you had enough drainage for your plants given the extra rainy season? Cymbidiums usually like a lot of water, but they need a lot of drainage as well. You should probably check the medium to see if there is any sign of rotting. Then you’d need to repot them. We just released a guide on cymbidium orchid care. This should help you. – Mary Ann

  16. Kizito Paul says:

    Am kizito Paul Uganda east Africa we are in the tropical region ,ive kept cymbidiums for 5 yrs ,i only saw 1 blooming but also dried out before opening , i have over 400 pots.my question is our region good for them because ive done the best advise .

  17. kiki says:

    I have had my cymbidium for about 3 years and it has only flowered once(when i first bought it). I keep it indoors in a bathroom(no shower humidity) but, our bathroom does have a sky light which provides sun light. The leaves are a bit dry and stiff but have a good light green color, and no spots and little to no yellowing on the leaves. Recently new leaves are forming, they look as if they are a bit scrunched? i have never fertilized the plant but i do give the soil?bark? a replacing?(i am not repotting entirely just replacing the top layer as best as i can without disturbing the actual plant)
    any recommendations to get it to flower? also temperature wise ranges from 50 degrees to 72 degrees min/max within the year averaging at 63 degrees year round indoors.

  18. carmen says:

    with out sun just have a light thats work perfect

  19. michelle barbuto says:

    Thank you very helpful .great stuff

  20. kurt says:

    How many hours of good sun is necessary, to get Cymbidium to re bloom. Its late Jan in Tucson, so it gets cold at night and lots of sun during the day. What can I do top make them think its October? K
