    Most lightly it is the result of strong light in your area. As long as the plant/leaves can handle such a strong light, it should be okay, otherwise, give it less light.

    Without seeing a photo ,it is hard to say,But some Dendrobiums DO have a lot of color in the canes..I have one where the new growth is a lovely green but after that the canes are very red.

    I have a dendrobium with a strong red cane even when it is growing in an area of 40% sun.

    Vincent, what kind of Dendrobium is it? Not all Dendrobium are sun loving plants. 40% sun is a lot for some species or hybrids.

    Some Dendrobium canes do naturally have purple or red color, but a lot of them have those red or purple colors on the canes or leaves, for the most part, it has a lot to do with temperature and sunlight IMO. I would like to see photos also.

    I have abosolutely no idea what dendrobium is that. It's was grown in my school's garden and the gardener gave me a keiki. Mine is a small keiki but I will give you a photo of the mother plant when I manage to shoot it, if you insists.

    hi vincent,
    looks like d.crumenatum or in that section, they do turn reddish during hot/dry weeks, and flowering is triggered by cooler/rainy days.
