dendrobium aggregatum

[BettyE]

Didn't know this species needed a Winter rest for a year after I had it. Now, with a rest, it decided to bloom...BettyE

[WhiteRabbit]

Yay! It's lovely!

[Leafmite]

Very nice! I have one but it was buried by the passiflora vine and didn't get enough light to bloom. I am not going to make that mistake this year.

Yay Betty! Yes, they need a cool dry rest and will bloom reliably every year. I have a Den. Ueang Pheung (Den. jenkinsii x Den. aggregatum).
I rest it outside all winter no water and nights upper 40s and it blooms every April - May

My jenkinsii and lindleyi var aggregatum began their winter rest today.

It's going to be hard for me to keep my watering devices away from them for that long.

The compromise will have to be the occasional misting.

*Crossing fingers that they will reward me with flowers in September/October*

Andrew...yours is very well grown, and beautiful. Perhaps someday...BettyE

Thanks Betty, mine is actually only in a 3 inch pot. I think same size as yours ?
How long of a rest did you give?
Cool nights too?
And also almost daily watering a weekly fertilizing during summer?

[BettyE]

Yes, Andrew, it is watered weekly with growth fertilizer. ( 30-10-10 ) at a rate of 1/4 teaspoon per gallon of water. Every fourth watering is plain water. I guessed at how long to rest it; I believe it was from Thanksgiving to the first of April. How long was yours "rested?" Maybe with some schooling by you, mine can possibly look better next year! Thanks for any help you can give me...BettyE

P.S. It never gets below 50 degrees in the greenhouse.

Just wondering, how important are the lower temps. I have to choose either lower temps and lower light (60-65F south window in winter w/ weaker light) OR higher temps, higher light (65-80F close to T5s). It is mounted and doing extremely well now.

While some lower temps do help harden them off, light is definitely much more important for proper blooming.
