How about jenkinsii, since it's (sort of, I guess) a smaller version of aggregatum?

Stephen, according to Orchidwiz, jenkinsii should be allowed to dry out completely between waterings but not go dry for long periods of time.

I know there are...and always will be...questions regarding this subject. BUT the thought behind this particular thread is to gather a list of what our members actually rest in their collections...not as a debate on whether something should or shouldn't be rested.

Please use this thread to list anything that you personally give a winter rest...any questions and/or debates should take place in a separate thread...there are many threads already in the forums regarding this subject...or you can start your own

Thank you

I had thought all along this would be a collection of "how we do it" posts. As such, I think we (so far) are right on the mark. There will always be differences between ways people grow their deciduous (winter rest) orchids, but in the long run the info should be of value. Let's hope people don't get to the point where there is only one way of doing things. There can't be, because the Orchid Board is global. Let's hope contributers don't post thinking their methos is the only way. Sorry, off soap box.

[cb977]

The discussions are fine, it's what we're all about...but I was hoping that this thread would be just a listing of what each of us actually do in our own collection and the real discussions about why something "should" or "shouldn't" be could take place in the forums.

You need to consider where the advice is coming from, and whether it really applies to your locale. For instance, everyone in S. Florida knows the time to start tomatoes is now, but in Michigan, people are prepping their beds for snow. Plus it's colder up there, and the day is getting shorter up there, and most plants are much more dormant anyway in colder weather. I'm sure Ross's plants are probably not pushing new leaves right now. Plants do what they do based on the climate you're giving them. So if they're still growing, let them grow. You can't really force them to rest without some consequences.

I personally find it easier to just look up the cultural requirements in a decent book(or culture sheets like the ones the Bakers put out) and see where my climate fits or doesn't fit. People on the various forums have too many variables to really take their advice without a salt shaker.

And for the Dens in my list at least, while they have a "dry" season, it's not desert dry, it's mid 70s temp, 80-90% humidity and rain every couple of weeks. So there's still water in the air.

So yeah, anosmum is my very first one that actually needs a DRY winter rest.
I also have Den. jenkinsii and it's still growing now. I'm planning on cutting back the water after the new bulb matures. My brassavola nodosa has been "on and off" so I'm not sure if it needs a short rest. and quite frankly, Neofinetia is suppose to rest for winter but it keeps on growing.
Thanks for the respond on anosmum. I will hang them outside with night temperature about 50s until the end of this month when temperature drop furthers and we shall see how it reacts.

Flowering is mainly in the dry season, although can occur at any time in New Guinea. (So I'm going to assume that New Guinea is wet all year long.) The plants mus be given a dry rest during the colder weather if they are to flower well. (So that begs the question, what is flower well? Do you want a big display once a year, or flowers all through the year, which is what I think may be the options here? )

What is the title of the Dendrobium book? It sounds like something I would really like to read....

My list of the few I have that need a winter rest seem to have all been listed, but I will list them in case I missed something...

Den. anosmum (superbum)
Den. unicum
Den. nobile hybrids

I saw something mentioned about a cymbidium? Or so I thought? What about Gymcymbidium? Anything with them, I dobut it but thought I would ask.

I hadn't heard of the Neofinetia needing a winter rest until this thread either. Anyone else rest them? Is this agreed in the Neo world?

[Leisurely]

Den Bractescens
Den Lodigesii
Den parishii
Den (Nobiles)

And I quit right here because I was just thinking that there are different types of rest. There is a complete rest where you provide no culture and there is a partial rest where you might completely stop fertilizer but provide water in much lesser amounts than previously provided. A winter rest cannot be that generalized and might be very misleading to some people. Winter care depends on your individual growing conditions and the plant itself. For example: I have Den. Gatton 'Sunray' FCC/AOS. Beginning in mid November this plant gets no water until mid February. It usually stops growth around Oct. 1. From Oct. 1 to mid Nov., water is reduced from daily drenching to weekly sips. So maybe this needs to be changed to COMPLETE REST and PARTIAL REST.

Hi Jerry...thanks for your input

You are correct in bringing up the many different ways people (and plants) determine a "rest"...if somebody is not sure about what to do but sees the plant in question in one of our lists, I would hope that they ask a question and I'm sure the member who posted the list will explain what they do...in their environment

This list is just meant to be a general listing of what individuals do with their own collections.
