    Wink Cymbidiums galore! What now? HELP!

    Hey folks! I've ordered my first Cymbidiums in a crazy effort to try something new and challenging. I understand they get quite large, and I actually managed to find some tall cache pots that look darling with the plants in them, so I think I have done a good job potting them up. But here's where I'm confused....

    One of my cymbs came in bloom...it's a Cymbidium Rose Passion. Here's a pic (it's kind of lousy...the blooms are already fading from being shipped in the freezing cold, but you get the idea).

    Anyway, you can see it's a fairly big guy...but it smells heavenly! I also bought four other cymbidiums that did not come in bloom. They are (left to right) Cymbidium Pistachio Mint, Cymbidium Radiant Pearl 'Geyserland,' Cymbidium Sussex Court 'Not Peace' (Peloric), and Cymbidium Yai Monica. Here are pics of them:

    Now, I got these RIDICULOUSLY cheap (as in "99 cents per bulb" cheap), so some of the bulbs aren't in the best shape, but once I get new growth on them I think they'll be fine. The question is...what type of temps and light should I give them this time of year?

    They were originally purchased in Hawaii (by my vendor), then shipped to California, then packaged up and shipped to me (bare root the whole time in shipment). Since they're not in bloom, I'm not sure if I should give them a "warm and sunny" spot to encourage active growth or a "cool and sunny" spot to encourage them to set buds. I know these guys need a prolonged cold period before they will bloom, but I'm thinking I probably missed my chance already for this year for these plants, so should I just go ahead and keep them in warm sun and wait until next fall/winter to give them their cold spell? I'm pretty sure these poor plants are just about as confused as I am at this point after passing through so many zones!

    I am quite lucky in that I have nearly all growing environments in my house SOMEWHERE. I have dark and cool, dark and warm, cool and bright, warm and bright, and just general intermediate somewhere in my house at all times. Where shall I place these cymbidiums at this point in the year? I'll put the non-blooming ones wherever you advise me to, and then I'll place the Rose Passion with the rest of them once it's dropped its flowers, which won't be long now.

    Also, one of them has a bulb that looks like it has gone rotten. Should I detach this bulb from the plant? The roots on the bulb don't look bad...just the bulb itself looks yucky. Here's a pic of the questionable bulb:

    And lastly, can any of you Cymbidium lovers tell me if any of the plants I've purchased are compact growers? I've noticed that the leaves on some plants seem skinnier and the p-bulbs smaller than on the other plants...it would be nice if they didn't ALL grow into plants that need their own zip code.

    Hehee!

    I'm a total Cymbidiot...I feel like I'm staring at pots of overgrown day lilies and I don't have a clue what to do with them! Please help!! Thanks, friends!

    Thanks “OrchidAddict” for starting thread regarding Cymbidiums and your experience. It’s an informative thread for me.

    Hehee...you're welcome...(you can call me Jenn, by the way!) You did see the part where I said I was a "Cymbidiot," though, right? I'm mostly just guessing here from stuff I've read on the internet. I'm far from being an expert in these plants, and I'm hoping an experienced Cymbidium grower will pop in soon and give us some tips! Let's stay tuned....

    Cymbidium growers...where art thou?

    Yes “Carolla” you are right. I totally agree with you and I am also looking for more information about Cymbidium and its growing method.

    I am just about to purchase my first Cym and would love to know whether they need to go outside in order to bloom? I live in the UK and we get some dark weather over here but I have always heard that they need to be outside in the sun in order to bloom. Well, I live in a tower block on the 14th floor so for me putting them out is not an option. I know what would happen to them if I turned my back for one minute so I really can't have them outside at all. Should I go ahead and get one anyway? I have always wanted a large green but have never managed to find one but I found one the other day so should I? could I? ....

    being that they were just potted up don't place them in high light for a couple of weeks while they get established. You then want to gradually increase the light to as high as possible 3,000-4,000 fc. You want the foliage to be golden green colored. During active growth they get watered well and fertilized well. Give them the cool down in the fall. If you google "cymbidium culture" you should get plenty of info. I don't know if any of these have oriental Cym backgrounds.

    If you can meet their requirements inside, then give one a try.

    A very good deal that. At that price, experimenting is very affordable.

    Though you already have considered this, I'm sure, make sure:
    1) the cache pots do not fit so snugly as to hinder air circulation in the media
    2) after watering the pots are allowed to drain thoroughly before replacing back into the cache pots
    3) to securely brace the pots should you put them outside -- as top heavy they can be, a wind will knock them over easily

    You did. Don't bother attempting to initiate spiking.

    What Ron said. Aim for warm bright light for a couple weeks. Then put them outside. Harden them off until they are receiving full sun most of the day. Had one huge cym given to me a couple years back. I cleaned it up (it had scale) and had it outside on my SE balcony. Completely unobstructed sun from 8am until around 2-3pm. No problems with scorching. Gave it away the following spring as I was unable to give it the necessary chilling long enough to set spike.

    During active growth they are usually water and fertilizer pigs. Quit fertilizing in the fall and start cutting back on the water.

    If the bulbs is mushy, absolutely. If completely brown and shriveled, then yes you could and now would probably be the time to do it as the plant is going to be adjusting to its recent "trauma" anyway. You will need a strong blade in all likelihood.

    Your best bet, Jenn, would likely be to contact the actual grower in Hawaii and inquire from them.

    Susie, first you need to figure out what kind of conditions you can provide and how much space you have available before you can answer that question. All cyms -- to the best of my knowledge -- are high/strong light plants. That is the first cultural requirement you need to meet. If you can't, then look no further. Can you provided the months of cooling down one would require (temps 7-10C)? If not, then you must rule out any that require a cool down -- which is most of the ones commonly found in cultivation. There are some warmth tolerant to warm growing cyms and there is breeding being done to increase the options here. Cym Golden Elf is an example of a warm growing cym that desires no cool down to bloom.
