    Default Cattleyas and Oncids - How do I acclimate them to growing outside?

    I'm ready to send my catts and oncids (and maybe my 2 zygos) out to play, but I don't want to shock their systems. Where I live, this is spring and daytime temps are 60s-70s and nighttime temps are in the 50sF or higher. But we do have the occasional drop in temps into the 40s.

    I know with regular plants, when you put them outside at first, you "harden them off" - that is, you put them out for a certain amount of time each day, to get them used to being outdoors. But is it the same with orchids? Most of my orchids are intermediate growers and I really think the catts would benefit from more light. Of course, my paphs and phrags will stay inside, if only because they can't handle the brighter light.

    But I'd really like to get the others out of my living room for the good weather.

    Any ideas, techniques, warnings??????

    Thanks for the help -

    Maura

    I would not recommend till late March or early April to put your orchids outside for better. Till then you could put them out on sunny days and warmer temperatures in half shade, and bring them back at night (This will be a lot of work though )

    Thanks so much, Amey - I was afraid of that - I'd like to get the more monstrous catts outside asap, but not at the risk of losing them. My cyms have been outside through this particularly mild winter and seem pretty happy about it, but I know they're much cooler growing. Patience, patience.....

    Harden them off same as any other plant, Maura. I would agree with Amey that you would be best off waiting for temps to warm up a bit yet. I think I'd wait until night temps are in the low 60s. Sun-wise, you can hang them under if tree if one is available and then move the high light lovers after a week or so to a bit brighter location, & repeat until they are getting the sun they want.

    Hey Maura! Thought I would chime in as I am in a cool climate...the best advice I have received for moving temp tolerant plants outdoors is to wait until temps are close to ideal so that they experience the natural seasonal shift as things start cooling off during the fall. Of course, this advice was concerning plants that would remain outdoors even during winter after the acclimatization. I'd say you've gotten good advice from the above members.

    Hi Maura if you insist to do make sure you do it slowly maybe you need to expose for one hour for today and the next morning 2 hour for few days then slowly increase the exposure time accordingly. Dont do it drastically otherwise the black spots or burnt marking will appear on the leaves look very ugly like my plants below.Leaves of Vanda tricolor and Vandopsisi gigantea.

    Thank you, Zain. That is certainly a powerful warning! I'm so sorry about your vandas, but with your excellent care, I'm sure they will be stunning soon enough. Thank you for taking the time to post the photos - I'm very appreciative and I will take all this good advice to heart. Besides, as things would have it, we've sunk into a brief cold spell here, so I'm feeling a lot less like "spring cleaning" than I did earlier this week! Actually, we had a very bad storm move through the middle of the States, including part of the South (where I live) last night - tornadoes did a lot of damage and killed 28 people, but we just had trees down and power outages around here. But the moral of the story is that it's a good thing my orchids weren't outside last night - even my cyms got knocked over.
