[OGD] Novice question on Phragmipedium kovachii

2006-01-04 Thread Dinesh Fernando
I live in Sri Lanka and have never seen a Phragmipedium plant or flower,
except in photos.  If I may ask a seemingly "dumb" question: what is so
special about Pk vs any other Phragmipedium plant that makes it so valuable?

[OGD] Sri Lankan orchids

2005-08-21 Thread Dinesh Fernando
I happened to pass a road-side tree that had been cut-down a few days ago.
A number of orchids were attached to the tree trunk, and they seemed
"dehydrated" (is that the correct term for a plant that's not got sufficient
water?) and also seemed unable to cope with the full sun that they were now
getting (plants were partially shrivelled).  So, I brought as many plants as
possible, tied them up on various trees that provided varying shade
conditions - I don't know how much shade the plants would have received in
the wild - and watered them .

I'd like some advice on how to preserve these plants - the best means of
reviving them, and re-establishing them on trees.

I'm a total novice at orchids, so my knowledge is limited.  The plants
looked to me like a vandaceous orchid, but there were no flowers on them.
Are there any published books on Sri Lankan orchids so that I can attempt to
identify the plant if and when I get it to flower?

Thanks,

Dinesh.

[OGD] Novice question: scale

2005-08-21 Thread Dinesh Fernando
I have a scale infestation that's spread very quickly to half my collection.
Given the way that I've grown my plants (mounted on concrete strips), it's
not practical to treat each infected plant individually, so a systemic
insecticide seems my only option.  I bought such insecticide and made three
weekly applications, but the scale is still there.  Since the preparation
was made following the manufacturers recommendation (X ml per Y litres of
water), I suspect the amount of pesticide that I applied per plant was too
low.

My question is, how much of insecticide should be applied per plant: i.e.
10ml, 20ml ... etc? And how do I know when the infestation is controlled -
i.e. how do I know the pests are dead?

Thank you,

Dinesh.

Welcome to the list Martin.  There are many "orchid experts" on this list,
as well as other raw beginners (like me).  I've learned quite a bit by
reading other people's posts.  So ask away ...

[OGD] Dendrobium hybrids in Singapore

2005-03-21 Thread Dinesh Fernando
I will (probably) be visiting Singapore for a very short visit and would
like to visit some nurseries specialising in dendrobium hybrids for tropical
cut-flower markets.  If anyone knows of such nurseries, could they please
e-mail me their contact details (names, e-mail addresses etc.) - preferably
off-list.

Thanks and regards,

[OGD] HELP!!! Something's eating my roots

2005-01-11 Thread Dinesh Fernando
I live in Sri Lanka and have some dendrobium hybrids growing on coconut
husks.  Something is eating my plant's roots - it seems to prefer the green
root-tip but has also eaten the white roots as well.  Could anyone tell me
what's eating my roots and how I can get rid of it.

Can I also ask why the root-tip is of a different colour to the rest of the
root?  Does it have a different function?

My apologies if these questions sound dumb.

Dinesh.

2004-11-09 Thread Dinesh Fernando
We use metaldehyde mixed with rice-flour (different types of flour should
work as well) to make something like a 3-4% metaldehyde base.  This is then
mixed with fresh beer to form a thick paste.  We then make small balls out
of the resulting paste and put one on each suspected plant's potting mix.

Hope this helps.

[OGD] Growth media pH and EC

Do you monitor pH and Electrical Conductivity (EC) levels in your growing
media?  I was wondering if anybody does this, and the implications of
monitoring pH and EC.

Thanks,
