Advice, please: D. laevifolium
I have a Den. laevifolium, nicely crowded in a 1 1/2" pot, which got off to a
rocky start when my GH overheated 2 years ago, but is now leafing out beautifully. Question: Is it time to dry it out and stop fertilizing, and if so, how completely and for how long? Tom Walnut Creek, CA Nikon D70 |

Good question, Tom. I've been wondering the same. Mine is in a 2" pot and
has filled the pot over the summer. Lots of leaves and new growths at this writing. I'll await the same answer! Garland "tbell" wrote in message ...

Tom, Garland, let me quote from one of my bibles - "Dendrobium and its
Relatives" by Lavarack, Harris & Stocker. All three are highly experienced & qualified, & their work involves them in the orchids of the region from which D laevifolium comes. "... occurs in several islands to the east of New Guinea ... It grows from about 300 m to 2300 m altitude, in damp moss forests where it often occurs low down on tree trunks ... While this species can be grown in warm conditions, cool to intermediate temperatures are preferable. It can be grown on a slab, but a pot of well-drained mixture is best, as the plants must not be allowed to dry out. Year round heavy watering and shaded conditions with high humidity are necessary." It does *not* need to be dried out, & (depending on how cold your winters are) do no more than reduce fertilising& watering in the colder months. I have a plant that I was growing successfully in sphagnum in a saucer. Since nearly all my collection is in bark & this was watered in summer with the rest, it was *sodden*. And it did fine. Kept the sphagnum at least damp through the winter. I've worried about that, & recently repotted into bark in the saucer. Not sure if I did the right thing. Forgive me for climbing on to a hobby horse for a moment: Dendrobes come from such an incredible range of environments (hot wet steamy jungles, Aussie monsoon areas with hot *dry* weather for 9 months - no winter, up to China, into the Himalayan foothills, evergreen forests, deciduous forests) that the old mantra of "water in the growing season, dry out in the resting period" can well be disastrous for a plant, depending on where it comes from. You *must* know a species' natural environment, and at least get somewhere near that. They are adaptable to a degree - I have tropical phalaenanthes growing within metres of temperate dendrocorynes, with the only considerations I can modify being light & watering. But you still need to be aware of their preferred environment. Use a library - you only need to look it up once for each species. Complex hybrids? Ask someone who grows them, or guess from their constituent species.

Thanks Dave. I'm pretty much giving the plant the conditions you describe.
It is growing wonderfully. I'll just be patient for a while and see what happens. Garland "Dave Gillingham" wrote in message ...

One of the members of our society, who is involved with orchids in the herbarium & has a special interest in the Dendrobes, suggested D. gibsonii. That's from Section Dendrobium, which surprises me a little having read up on it after last Tuesday's meeting. My plant's inflorescence started life in a sheath some 50 mm (2 inches) or more long. In my admittedly very limited experience, plants from that section all form individual buds rather than the inflorescence bursting from a sheath. But I did mention the sheath to him, & his knowledge is certainly far superior to mine.
