As night temperatures
drop, simply place your plants close to a window that is
cracked at night, to let in a little cool air. Give your plants this
treatment for about 3 to 4 weeks and you should begin to see flower stalks
emerging soon after that. This works very well with healthy phalaenopsis.
How
low should you let the night temperature drop? For cooler growing
paphs, phals, and
cattleyas, temperatures of about 55 to 60 degrees should suffice. Make sure
your plants are not in a cold draft, and protect them with a light
curtain if needed

| Placing
your orchid plants in an unheated room at night will also do the
trick. Remember that day temperatures also need to be at least ten degrees
higher. If your orchid plants have been growing outside this summer,
you can simply leave them out for a few more weeks. If temperatures
threaten to fall below 55, all but the coolest growing of orchids,
such as cymbidium species and hybrids, should be brought in. Your plants must
be healthy, and well care for to respond this treatment- if a plant has
just flowered, don't expect it to bloom again right away. This method generally
works best with orchids that have their natural flowering season in the
fall through spring months, including most phalaenopsis (moth orchids),
paphiopedilum or paphs (slipper orchids) and nobile type dendrobiums
such as Dawn Maree hybrids. Give it a try and you
may be surprised when that reluctant orchid finally puts on a dazzling
floral display. See our other tips for getting your
orchids to bloom |
