I've edited the thread title to add the species name, so hopefully that will help get more replies :)

Found some info here: How We Grow Dendrobiums, Part 2 « RF Orchids
Quote:

Water. ... Their native conditions are fairly wet during the late spring, summer and early fall. Rainfall can be quite heavy for a few months, but it tapers off in the late fall, and winter months are fairly dry. Water the plants regularly when they are actively growing; mounted plants can be watered daily if air circulation is good. When the new pseudobulbs have matured in the fall, gradually reduce watering, and allow the plant to dry between waterings. There’s some moisture in the habitat at this time, so the plants do get a little water from dew or fog; a light watering every few days is all they need. It is normal for the pseudobulbs to shrivel somewhat during the resting period, but don’t allow the plant to dehydrate completely! During the coolest periods in winter, keep the plants fairly dry.
Hope some members who grow this will chime in!

Good luck!

I have mine in a room that's about 60%RH and about 75-55 degrees. One under lights and one in a east facing window. I cut way down on water and no fertilizer in the winter, they grow like crazy but they have never bloomed for me and I've had them about two years.

I grow one mounted and one in a pot, both in GH, but neither has bloomed for me.

My dad had an orchid nursery in Denmark. He grew Den aggregatum together with Cattleyas, but moved plants up high on the wall, so they got high light and no water from Dec thru Feb. Combined with the cooler winter temps (probably down to about 15C), they bloomed under those conditions.

I read people call it 'aggravatum' because of all the trouble it gives them to bloom.

I have 2 of these and this time they are on a fast.....no food or water. Getting sunshine. Will see what they do. I may throw them out if they do not bloom.

If you tell them that, it might help . . .

I believe the new name is now Den. lindleyi.
