    Hi Jim,

    Do we need to pour the water over the roots or the plant itself (including the leaves)? How often can this be done without damage to the plants? I heard some folks say that we can even place couple of ice cubes in the pot during winter and that should help give a sudden drop in temperature that some of these plants require (especially cymbidiums, as the cooler ones are not easy to flower in the warm tropicals). Your inputs would greatly help us!

    Dendrobium crumenatum needs a "sudden" drop in temperature, not a continuous cold period to initiate its flowering buds. Pour the cold water over the entire plant, roots and all. I would not use the cold water method any more than a couple of times a year as the flowering process is a big energy loss for a plant.

    Hi Jim,

    Are there any other species (specifically dendrobium, cymbidium, coelogyne) which would benefit from such a sudden drop in temperature? I am assuming this needs to be done in the winter. Please correct me if I am wrong.

    Thanks
    Satish

    Hi Satish,

    Dendrobium crumenatum is a lowland species, as you probably know, and it is accustomed to high temperatures during the day and only slightly lesser temperatures in the evening. A couple of other species that will flower with the same treatment are Thrixspermum unguiculatum and Flickingeria scopa. The flowers of all these species are short-lived barely lasting 6 hours. I doubt that genera whose flowers are long-lasting would benefit from the "cold water" treatment.

    My only experience with the "cold water" treatment is with species that are from the Philippines.

    I notice you are from India and I would suggest that next time there is a thunder storm, the usual source of a sudden temperature drop, see what orchid species flower about 7 to 10 days afterwards.
