(22-Oct-16) Four months ago I acquired a Rossioglossum grande with 3 small bulbs and a new growth. The new growth has matured and produced a slightly larger bulb, and has now put out a vigorous new growth. R. grande is supposed to need a 'cool dry winter rest', so should I now lower temperatures and withdraw water, or should I keep it going and let this new growth do its thing? Current greenhouse temps are minimum 14.4°C, rising to around 21-22°C during the day; I have a cool conservatory to which I'm planning to move all my other orchids that require a 'cool winter rest' next weekend.

Thanks in advance to anyone who can advise me!

Paul

Are you sure it's grande and not a hybrid? In my experience grande has a very strict summer growth pattern and flowers in autumn (mine is in bud now). I think that Rawdon Jester grows at various times of year, but I haven't grown it, I'm sure others can advise. If it is grande I'd keep it warmer and water until the new growth matures.

I agree with the above. I have Grande and also Williamsianum which are the parents of Rawdon Jester so I treat them all the same - min 13c with no rest because they are part of the Oncidiinae family. They all flower profusely.

Thank you for your replies. Yes, that was my feeling also and so I left it in the greenhouse, intending to keep it going. However, the plant has delivered its own verdict - the new growth has died back! I have taken the hint and moved the plant to the cool conservatory for the winter.
