I had a problem comprehending what
OGDers expect of "foliar feeding" but was reluctant to weigh in to the
subject out of deference to blaspheming the mystic beliefs of devotees of the
art. Leo's post [OGD V7 #369, Message 5] says it all.
The concept of "foliar feeding" is based on

When I invented my fertilizer ( Green Jungle) I spent 9 years trying to
figure it all out. I went to the jungles of Peru, Borneo and others and
studied everything. Soil, water, leaf analysis, temperature everything. One
thing I discovered was that Orchids have fixed open stomata which allow the

Jerry's observations add a lot more to the debate than some of the old regurgitations on this topic. Steve, are you sure that Cattleyas are CAM cycle plants?? I was not aware of this. Can you provide some references? I know that the genus is widely dispersed so there ma
With regard to the mechanism of foliar absorption of nutrients,
John Stanley [OGD V7#372 message 3] is right; the wonder is not the
advantages of foliar feeding but that it can taker place at all. As I
recall, it was Tom Sheehan who obtained experimental evidence for its existence,
but I di
Title: Foliar Feeding.
Steve, thank you for the reference. I am not too sure that they are authorities but it does provide food for thought, at least for Cattleya culture. The fact that they list Cymbidium as a CAM plant causes me to be cautious. Private research in The Netherlands has not co
You are aware that not all orchids have fixed stomata. Paphs for
instance can open and close them. CAM plants, which are mainly the
hard leaf type orchids cannot regulate their stomata that well from
what I understand, such as Cattleya.

My rant and rave for the day:
I don't understand people who think foliar feeding is unique or
something special. Promoting foliar feeding as something different than
standard cultural practices is a pile of hogwash. The technique I use is
the same that 99% of all commercial growers use an

Leo,
Where does this rant come from? I have used foliar feeding for some
time and I simply am not impressed with the results in general, but it
has its specific uses.
For orchids, foliar feeding through misters is typically a bad idea
for adult plants, as the water can easily get caught in

What is with the rant, I have seen nothing where I or anyone has said
you should fertilize the leaves and not the roots. Foliar feeding as
