Dendrobium Parishii rest period
 
I am confused about the rest period of Dendrobium Parishii. Some sources say that they require cool winter temperatures, others say keep warm all year, and the rest say give intermediate. I don't know which temperatures to give so I decided to give intermediate winter night temperatures (60F-65F). What should the temperatures be for the rest period? What month should I observe its rest period, is late october a good time?

As a rule of thumb, I stop heavy watering after new growth has stopped growing or slowed a lot.
For me thay happens after the first cool front moves in.
I continue to give Cattleya light and will water once a week.
As the temps drop I move all but the resting Dends into the GH.
I only move in to protect from freezing temps.
By spring all leaves are gone but flower buds will develope at the nodes.
I hold water until new growth apears.
Some folks hate to not water thier orchids, just think of them as decidious trees that lose leaves in fall and grow new growth in spring.
This is what the work is all about: IOSPE PHOTOS
Good luck

Can't speak to this one but anosmum also requires a complete rest to bloom. I stop all water and fertilizer at end of October till I see some evidence of new growth in spring (usually about March). Then I resume full watering with fertilizer. This is result http://www.orchidboard.com/community...uperbum_01.jpg http://www.orchidboard.com/community...uperbum_02.jpg http://www.orchidboard.com/community...anosmum_01.jpg

They should drop all the leaves and end up leafless stalks if they are to blossom.

Gorgeous colour combination! Thanks for the advice.

Not sure the coolness is a mandatory feature, but dryness is.

All of the "winter rest" 'chids I have get their food and water taken away the first week of November. They continue to get high light and just an occasional "barely-there" misting until the first week of March when they are eased back into their usual feeding/watering habits.

The misting is not directly on them...it's more of a carryover from the plants around them and I don't take my finger off the trigger while passing to the next section.

We are together on this one! :biggrin: I use Halloween as the signal, but 1st of November is pretty close :biggrin: Then I just watch for the plants to tell me when they care to resume growth. There will be little green nubbins of growth where the new shoots will be. The flower buds are soon to follow.

Oh, and I don't mist, so that's not a situation for me :)

I think the timing can vary depending on where you live and what your conditions are. Here in Florida, early November can still be quite warm so it might differ from someone living in a colder region.

I'd use all of these suggestions as very general guidelines and adjust them to your conditions, Jeremy :)

I would say that den. parishii is a minature version of den. anosmum and they probably require the same care. In my growing area the average temperatures during october to november are 77F day and 64F night. And the coldest averages occurs in December with 77F day and 61F night with an occasional dip in the upper 50s F on those extremely bone-chilling cold nights. So I think that I will scare my parishii into dropping its leaves on Halloween :) by withholding water. Thank you everyone.

I have a very small Dendrobium parishii that was a keiki. (maybe 5 inches tall) Not sure about water in winter with a baby. Inside grower. Any helping thoughts?

Maybe I just found the answer to my question. I think I treat it like a baby until it get a mature cane, then gets a winters reduced watering, no fertilizer.
