Subject: [aroid-l] Cultivation of Anthurium Warocqueanum ?
I have been working with the growing of the Anthurium warocqueanum and A.
veitchii for a while - and have had reasonably good luck establishing an
acceptable greenhouse environment here in the Houston area (so far). I have
a number of plants to work with (thanks to many of you) and have had good
new growth after the acclimation period. But I do have a persistent anomaly
that I am hoping that some of you experienced growers might be able to help
me with. The warocq's develop nice new sizable leaves pretty consistently -
but frequently as the new leaf "unfurls" - or "opens" there is a significant
weakness in small areas of leaf tissue between the veins - and this weakness
develops into a translucent spot that soon develops into a complete
perforation - sometimes quite small 2 to 4 mm in diameter - and of course
the result is a permanent "blemish" -- and on a few occasions the fault in
the new growth is near the main rib and after "opening', the new leaf has a
And now my question is what causes this problem - which has been pretty
consistent over the past few months ?? Might it be a nutrition deficiency -
a watering problem - a greenhouse environment problem like humidity or
temperature range/variation or what ??
The problem is only associated with the warocq.'s - the veitchii's new
growth (in the same environment) has been excellent with numerous nice large
perfect leaves - very rewarding !!
I understand that diagnosis via e-mail is very difficult - especially with
so many variables - but I was thinking that some of you may have had similar
experiences -- and if so your help and advise will be greatly appreciated !!
This experience has been most frustrating - since success has been so close
but yet so far !
Many thanks, Harold Beck
