Den. lindleyi (aggregatum) question

[Shannara]

I have a question for those of you that grow Den. lindleyi and jenkinsii. I have several of the lindleyi and one jenkinsii and was wondering what you do during the winter months to promote blooms in the spring.

Vendors have told me they withhold water from the plant completely, some for 4 weeks and some say up to 6 weeks. I was curious what those of you have these Dens have done that resulted in successful blooming. And when exactly do I need to start the dry rest period?

Thanks so much!

Don't have aggregatum, but i have a few jenkinsii. I leave mine outside down to freezing, in almost full sun in the winter. I water it about once a month, but they get dew almost every night. I start this when the weather starts cooling off for winter, and will start watering and fertilizing them when I see new leads starting to develop in spring. In summer, they get regular care, nothing special.

Two of the three plants I kept from the compot I had bloomed last spring with this treatment. Two are mounted, one is potted in a net pot with LECA. They are still pretty young too, so I'm looking forward to them getting bigger.

I withhold water for the month of December. I then begin watering at infrequent intervals until I observe new growth beginning. I then increase watering frequency.

Yeah I practically withhold completely and I grow mine down to freezing as well. After a month I might splash it with water but not water thoroughly and then like soft cane Den's I start watering when new growths appear.

I had a big aggregatum last year that I got at an OS function. I put it on the bottom shelf of my light shelves, where it was coldest...often in the 50s during the day, but as bright as I could get it under T5s, and didn't water it from Halloween until Valentine's Day (Nov-Feb). I basically ignored it. It sent up several spikes that were chewed up by some critter, but I still got three large spikes to bloom. It was just too big a plant for me to manage, so I donated it back to the OS auction this year.

I have one aggregatum. I was wondering this as well. I LOVE dens but haven't bloomed ONE in 3 years hahaha.
