    Default Re-potting and dividing orchids this time of the year?

    I need some advice. As I mentioned in another thread, I just acquired about 50 cymbidiums. Most or all of them are overgrowing their respective pots and in desperate need to be re-potted and divided. From what I have learned so far, the best time to re-pot is around spring time.

    My question; what are the cons if I decide to do the re-potting now on those that do not have spikes?

    Any help will be greatly appreciated.

    Marissa from my experience it is ok especially if you have mild winters, the temps. should not drop below 15 to 20 oC. When you repot an orchid, you injue the orchid roots, this automatically induces it to go into a growing mode and produce new roots, but if the other environmental conditions are not suitable(low temps. low light etc), then it won´t be able to produce new roots. It might then dessicate, still it won´t suffer very much, just that it will set back in growth.

    Well said, Amey. I agree Marissa. Good luck with the dividing and re-potting.

    Thank you both for your help.

    Okay, I live in So. Cali and temps in my area can reach as low as 38-40 degrees Fahrenheit which is -6.6 Celcius (assuming my conversion is correct). Is that still considered safe? Light is not an issue although it gets dark early (around 5pm) but we still get sun/high light during the day.

    Thank you Marissa for this post, it helped me. I fuss to much sometimes with my orchids. Actually I lost both my cyms to scales, but plan on buying some in the future.

    Sure, but don't let the wet plants (media/roots) get that cold. Best to divide early in the morning and let the plant dry out before it drops down so cold. We try to keep our greenhouse at 50+ degrees all winter. Any cooler than that and you risk cold damage. All that said, I only have about 5 or 6 cymbidiums. AND, the one that has to get really cold to spike is left outside until the first forcasted frost. That seems to be cold enough to get blooms.

    Hi, Marissa!
    I live just north of you in Marina Del Rey and it has been darn cold the last several nights-in the 40's. I grow everything, including the cyms in clay pots now and even with the cold weather and especially with the low humidity that we're experiencing right now I never worry about over watering. It is almost impossible to over water in clay pots, I think, because they breathe so well.
    I rescued a cym last weekend and it was drizzling outside & I just went out, took out all the dead stuff, potted up the good stuff, hit it with some seaweed extract to jump start the roots, a little superthrive and I'll just bet you that in a couple of weeks I will see solid new growth. I think in SoCal we are simply blessed with the kind of weather that orchids just forgive. If you have to repot than do it-you know that they are going to be a little shocky for awhile anyway. If they get enough sun and it warms up a bit they will start rooting again and I think the seaweed extract really helps. Best of luck and let us know what happens! Remo

    Hi Remo,

    Yeah, it's been cold lately. I have a few buds that are dropping and some spikes that died which I believe was caused by this cold weather. I don't use clay pots on my cyms. they are just too heavy.

    I may have to wait and see if the weather gets better before I do some re-potting.

    HI, Marissa,
    I haven't had any buds dropping but I have noticed the excruciating slowness of spike formation. I have some cascading cyms that are really taking their own damn time! Well, I know there is a lesson in that...the 'p' word-patience! Yes, the clay pots are definitely much heavier but they sure dry out good. best to you-Remo
