    Default mini cym culture

    I have 2 new mini-cymbidiums I am hoping not to kill. They seem different than my other orchids, a mix of phals, paphs, catts and oncidium. I have no idea how to care for them other than the basic culture sheet. One of them has had 2 yellow leaves. Is this from overwatering? I read that they like to stay pretty wet. I am growing them in an eastern facing sunroom where they get 2-3 hours of late morning sun a day.

    Any help would be much appreciated!

    Hi and welcome to the forums!
    I don't grow cyms so I can't help you, but I think Sue does...
    Ooh, paphs - be sure to post some pics of your plants, we love to see what people are growing!

    Good luck. I want a sunroom!!! Lucky you!

    Don't mini-cyms need the same culture as regular sized cyms? If so, I'll try my best to help you...but remember, this is in general, as to all cyms.

    Yellowing leaves is a natural process as older leaves drop off. If the yellow ones are the older leaves (at the bottom), then that's all right. If the newer leaves are yellowing, then there's a problem. You said two...that does not sound too bad, but as a precaution (or if more leaves continue to yellow) you should consider factors such as overwatering. Premature loss of leaves happen when they are exposed to cold or overwatering, just to let you know. For your cyms, it is most likely to be the aging process.

    How much are you watering? Water regularly, but don't water too often or let them stand in water.

    Are they getting direct sunlight? Be careful of sun burn! Leaves can easily become burned (looking like brown patches).

    If you are really worrying, then you can unpot them (though I advise you not to as this may be stressing). Cyms have thick and long roots in abundance, just like other orchids, they should not be mushy and brown.

    I'm not a cym grower, but has been reading some orchid books, so I hope this helped.

    Good luck,

    Hi Cinderella!

    The nice thing about mini cyms is that they don't need that cold spell in late fall to induce spikes like the standards do. Grow them warm, and with abundant light (your east window sounds fine, but if the new leaves start to go dark green, you'll need to increase that). As far as "staying wet" is concerned, don't keep them sopping. Their roots like to dry off to dampness in between waterings. Yellowing leaves on old growth is normal. Those leaves will brown and just fall off, leaving a naked pseudobulb.

    Thanks for all of your advice! As an aside, how can you tell when cymbidiums need to be repotted since their roots are so large and abundant?

    We usually repot when the medium starts looking like it's breaking down, but on cymbidiums, many people wait until the growths start creeping over the edge of the pot. Those folks say that the plants like to be rootbound, but I'm not sure how accurate that is....

    I have a cymbidium Golden Elf 'Sundust'....as you can see from the picture taken last year ,it bloomed like crazy. Twice a year( June&November). It was bursting it's plastic pot, so I repotted it last year,too,carefully cutting the old plastic pot off and gently placing it in a bigger pot and simply adding the mix around the sides.

    Well, the story they don't like to be disturbed is true..I had heard they can sulk for 3 years after being repotted. It's the end of June, and I haven't seen the start of a spike! So I wouldn't be in a hurry to repot if I were you.....

    I guess that I won't be repotting it soon, then. If this is not enough light, I could put it outside but I have never grown outside and I'm SCARED!! I don't have a set up. What about bugs, too much rainfall, etc??? I'm wondering what others did when they first started to summer orchids outside.

    Thanks.

    Cinderella,
    I am with you, don't want anything chomping on my plants. That being said I have two sickies outdoors on my back deck right now, and two Onc. on my front porch, which is enclosed and sheltered. I check everyone DAILY for any pest activity though, since they will eventually be returning indoors. Nervous though still.
