Ewww, fungust gnats.....
What causes them, what should I do water less?
The potting medium doesn't look broken down, and a lot of my phals are
spiking should I repot?
These little animals are sort of tiny, my sister showed me a photo of
some mealy bugs yesterday, so they can't be it, and none of them are on
the leaves either.
As I said, there's just a few in the potting medium, and they come
above and rest on the aerial roots each time I water & feed.
I was wondering as well, I have a phal bellina, a few days ago I was
looking at the roots and a few of them appear to be turning a brownish
color.
It can't be the potting medium because I took the plant out and checked
it, there's nothing breaking down.
Is it okay if I water with dilluted physan 20 once a month to sort of
ward off any potential for rot in the medium of my phal bellina, I read
somewhere that phal.bellina is a lot more susceptible to root rot....so
should this help a little...

I, too, wondered if it might be what we call "fungus gnats," or even

one of
the odd-looking ants, but either way the Orthene should work. If

they are
seriously nested in the medium, it would be a good idea to soak them

in a
dishpan of water [water level slightly higher than the pots] before
spraying. Kenni

Sounds more like gnats?

Wait a minute Kenni. Your advice is good if Sandra has mealies

but I
question if she really does.
If Sandra only sees mealies when they come to the surface after

watering,
what do you think?
Sandra, do you have mealy bugs on the leaves of your plants too?

If not,
are you really sure of what they are?

Orthene usually works for mealies, but these days you must read

the
labels.
The active ingredient is acephate [also sold as Isotox and under

other
brand
names]. You need one that lists acephate as 75% in strength [in

the
concentrate]. It has been coming out in more dilute

concentrations,
lately,
and these are not only ineffective, they are likely to create

resistant
strains. Good growing,

Hello, I've recently noticed that after I water a few mealy

bugs come
to the surface of my orchids...
What should I do to get rid of them.
I've heard of X-clude and Orthene, but I would really

appreciate some
personal input
Thanks, Sandra
