I've got some questions for other members on the
list about Hydrogen Peroxide in fertigation water. Pro's and Con's about it's
use. Here's what I know of it so far:
Pro's:
oxygenation of fertigation solutions
helps with preventing/irradicating fungi,
algae or bacteria
can kill or suppress certain
insect/fungal/bacterial pests when used with compatible pesticides
Con's: (not much here)
burning of roots or leaves
I'm having some problems with some of my potted
orchids. The symptoms are not affecting any of the orchids hanging in pots. I
know I've overwatered during the summer, humidity was low so I figured they were
drying out faster than usual (wrong!). Now I've got a bunch of orchids that are
losing their roots (shrivelled pseudobulbs and withering leaves, etc). The other
thing I'm experiencing are leaves starting to turn yellow at the tips and slowly
dying off to the point where the bulb loses it's leaf completely. It's not even
a nice shade of yellow!! I also am dealing with flat mites and that my be a
contributing factor in the leaf loss, but I'm not completely convinced it's the
mites causing the problem.
I'm rambling because I'm trying to figure this out,
sorry about that!
Can anyone on the list with experience
using H2O2 let me know their experiences
with using it, good or bad.
As always, I'm very appreciative of all your
comments and suggestions,
Cody
