Does anyone grow Dendrobium pedunculatum (AKA Den. speciosum var.
pedunculatum)? I don't know whether or not this species is slow
growing--or reluctant to put out new growths--but mine hasn't started
any new growths in nearly a year. It receives full sun all day long,
and the temperatures it receives are within the parameters indicated
for this species (it goes outside for our hot and humid summers, and
comes inside for a dry and very cool winter rest). The pseudobulbs are
nice and plump, and (judging by the purplish-red bulbs and leaves) I
believe that the plant's getting plenty of light (about ten hours of
direct sun each day). But for some reason (for lack of a better way of
putting it) the plant has just sat there and done nothing for the last
year. If anyone is familiar with this species--and knows how to get it
to grow better--please let me know. Thanks!

Where abouts are you located Steve???

Cheers

Is it a seedling or a division? If it is a division, are you sure that
it has some viable "eyes?"

It's somewhere between a seedling and a division. Since the plants are,
by nature, small in stature, I'm just guessing here; but it's at least
five years old and has five fully-leafed pseudobulbs and a few leafless
backbulbs. I did consider that it might not have any live "eyes." But I
can't see why that would be the case. It's growing in a four-inch clay
pot in nothing but pieces of granite, in which it made an extensive
root system in February 2005 when it was forming its last growth. The
bulbs are healthy (no rotten areas), and the plant seems "content."
Perhaps it's just its nature to be slow growing. I think I need to keep
it away from my Cycnoches species and hybrids. Compared to their rapid
growth patterns, the Dendrobium seems to be in a coma. :-)

Hi Steve

I too have a D. speciosum subsp. pedunculatum that is behaving the same as
yours. I don't know what the answers is as I have had my plant for about 10
years and some years it decides to add a new growth other years it does
nothing. Sorry I can't be of more help. Perhaps it is in the genes!

Anyone else had experience with this species?

Cheers

John

Hi Guys
Are you sure you have a D. speciosum var pendunculatum. 5 years in a 4 inch
pot!! C'mon. Give the poor thing room to grow. Speciosum canes are at least
25mm dia at the base and up to 300mm long. var hilli is up to 800mm long or
more. The leaves are wide and flat and up to 500mm long. They like a
moderate amount of water and a regular feed. This plant should be in a pot
at least double the size indicated. It needs early sunlight up to about mid
morning then mottled light until dark. This variety is very poorly in
flowering and may take 7-9 years to do so. If it fails to flower after this
time, give the plant more shade. The flowers will be creamy white and will
vary in colour. I live in Penrith at the foot of the Blue mountains west of
Sydney and speciosum grow like weeds in this area. For further info, check
out 'Growing Orchids' by J.N.Rentoul, book 4, The Australasian Families
Enjoy
Ted

Thanks for the info, Ted.

My growing conditions are just as you described - morning sun and dappled
shade in the afternoon. I have also read Jim's book as per your reference.
I guess mine is just a shy grower and flowerer.

Cheers

John
