Got this over the winter at Parkside. I managed to kill one of these a few years ago, but I guess I learned from my previous mistake: this one got a very good dry winter rest. It thanked me with a dozen nickel-sized blooms that smell like honey.

Very nice. Mine hasn't even started making buds yet even though I gave it a good rest. I noticed several new growths starting so I gave it a little water. My Den. aggregatum var. majus just finished blooming but only three spikes on this large plant.

When you mean very dry winter rest... What is the humidity level and temperature? because I think dry rest with 20 % humidity and 80 F central heating may dessicate it...

Humidity in my growing area averages about 50-55% over the winter, and temps are around 70 during the day down to low 60s at night. I think you might be right about your dessication worry.

Stefano, I am not sure if your question were directed toward me or not so I will answer it anyhow. My winter temps range from 55F to seventies and the humidity by day is 55 to 75 and 80 to 90 at night. The cooler temps and higher humidity prevents dessication. A lot of the deciduous spring blooming dendrobiums do what is called "ripen the canes". They plump up and become very full even with no water in preparation for flowering.

I have 3 Aggregetums, none look like they will bloom this year (very wet winter). Two of them I've been hanging in the patio when I think its going to rain.

I have a Lindleyi thats blooming, but 2 jenkinsii that are mounted and they also look like they won't bloom this year.

I dunno, maybe when it starts warming up soon (hit 83% today) they might finally push out some spikes.

My question was in general. Just feel the dry rest advice has to be given with the conditions. If someone is a total novice will toast their plants with a total dry rest in some apartment in the North East.

if you have a house with a room that is not heated or you are in the south and you can keep it outside you can keep them dry.

These Dendrobiums come from areas where maybe it does not rain for months but maybe there is either high humidity, morning dew, morning fog etc etc...

so it would not be dry like in the desert or dry near a radiator...
