Orchid is a wonderful and mysterious plant for me. Its flower is more
beautiful and charming than other flower. However, you must take care
of it very carefully such as temperature, watering, fertilizer,
humidity, light. Otherwise your orchid will not grow up or die
So I summarize some advises to take of the orchid as for your guide.
WATERING YOUR ORCHID
Always water early in the day so that your orchids dry out by
nighttime. The proper frequency of watering will depend on the
climatic conditions where you live. In general, water once a week
during the winter and twice a week when the weather turns warm and
dry. The size of your orchid container also helps determine how often
you need to water, regardless of climate conditions. Typically, a 6-
inch pot needs water every 7 days and a 4-inch pot needs water every 5
to 6 days.
The type of potting medium being used can also affect your plant's
water requirements. Bark has a tendency to dry out more rapidly than
sphagnum moss, for instance. It is important to remember, however,
that even when the surface of your pot is dry, the root area may
remain moist. Poke your finger or a regular wooden pencil an inch into
the pot; if it feels moist to the touch or if the pencil looks moist,
do not add additional water. The potting medium should always be damp,
but not soggy.
The quality of water used, whether for spraying or watering, is of
great importance. Since tap water has often been chemically treated,
generally with chlorine, it should be used with caution. The best
water for orchids is undoubtedly rainwater. Rainwater, as it passes
through the air, dissolves and absorbs many substances such as dust,
pollen and other organic matter.
THINGS TO CONSIDER: The temperature of the water is also important. If
the water temperature and the surrounding air temperature are equal,
no harm will result, and slight differences either way can be
tolerated by healthy plants. Fatal or long-term damage, not easily
discernible at first, can result from using water that is too cold.

I know very little about orchids. What kind of food do you feed a orchid?
Do they store their food? In what form and where? I thought they were
autotrophs. Shows how much I know.
BTW the ghost flower is a heterotroph.

Orchids need more phosporous in order to flower than the fertilizer
you describe. People mostly use synthetic salt based fertilizers. I
think proper maintenance is more important than fertilization. Misting
the plants daily and keeping them in clean conditions with as much
humidity as possible is optimum.

I am not familiar with the term autotrophs, but I do know orchids
(with the exception of some) are epiphytes and take nutrients from air
and water which collects between the roots or hold tights and the bark
of the tree the plant has adhered to.
I fertilize plants indoors using simple liquid seaweed and so far, so
good. I've had the same house plants for over a decade and made many
plants from their offshoots.
I also ran very large greenhouse operations and was a grower. But
what do I know. Rhetorical of course.
Remind me Don. What was your last post that addressed a plant problem?
It seems your whole "raison d'etre" for being in gardening groups is to
attack John. It would be a great improvement if you could just throw in
a few tid-bits that are on topic. Consider starting a new NG called
rec.kill.john.kill, then you could rant to your hearts content and still
be on topic.
here is 2 tree questions.
You say "fighting deadwood" Very loose terms and not lucid. I never heard
of such a thing.
Please explain what you are saying.
Define "dead" Define "wood" See, wood is not static so it may be hard to define like humic acids. Its
constantly going through ecological stages.
Very good question. People of course may disagree with my definition. That
is fine. I will provide you with my definition so you will understand what
I mean. If somebody else uses the word, you may want to ask them to define
so you understand what they mean.
Autotrophs make their own food. Heterotrophs have to have it made for them.
Not the last word on the topic. Most trees and plants are autotrophs.
E.g., An oak tree. An oak tree absorbs (not like a Bounty paper towel
though - that was just pointed out to me) essential elements dissolved in
water with non-woody roots and the help of organs, for example, mycorrhizae
and root hairs.
Mycorrhizae are composite organs consisting of tree tissue and fungi.
Root hairs are the extension of a single cell.
A root hair is the extension of a single epidermal cell, epidermal, which
Oak trees with the water, essential elements and trapped sun light energy
manufacture their food with the process called photosynthesis. Generally
speaking, after many processes glucose (tree food) is manufactured. One
reaction is the glucose is transformed into starch and stored in living
parenchyma. Trees only store starch in living cells. They load, store and
then use - water, elements and glucose as it is manufactured. The
collection of living cells is called the symplast. Most of these words are
in my dictionary. I call this type of organism a autotroph.
Even though the bag in the store says tree food, it is not tree food.
Elements are very important. That's why we call them essential elements.
Elements can be found here.
The most recognized essential elements for trees are -
C; H; N; O; P; K; S; Mg; Ni; Fe; Ca; Zn; Mo; Mn; B; Cl; Cu
Different species of plants require different amounts of the latter. E.g.,
legumes such as black locust, coffee tree have a unique requirement for
cobalt. I think it is pertaining to nitrogen fixation. A new topic to me,
i.e., the requirement of cobalt for legumes.
Now, there are, as always in nature, exceptions. E.g., The Ghost Flower.
It is a plant with no chlorophyll. It cannot photosynthesis and manufacture
its own food or nutrients. It gets its required food, nutrients etc., by
way of the bicarbohydrate transfer of plants. It then would fall under the
heterotroph category. We cannot provide food for the ghost flower. It is
manufactured by other plants and then transferred. What would you call the
host to an autotroph?
Animals such as humans are heterotrophs, us, like the Ghost Flower, have to
have something or someone else manufacture our food for us. We cannot
photosynthesis to manufacture our required food.
Glucose is the international biological currency. I require it, you require
it, other animals and plants require it. "All" is not a term that can be
used often. I am thinking, just a thought, that all living organisms living
on Earth require glucose. Without it we would not be here.
Sorry to post on top, but your reply is quite lengthy. I didn't see
anywhere in your post which tells me anything about how orchids are
autotrophs. In fact, you went off into trees again, and mycorrhizae.
Yes, trees indeed to depend greatly on the fungal mat, certainly in
harsh conditions, but mycorrhizae does not replace the function of
root hairs, it makes root hairs more efficient. The drip line of a
tree is most important because it's generally where the root hairs are
located. Trees indeed to depend on elements, and elements are made
available by micro and macro orgnanisms in the soil. I "feed" the
soil, not the tree. However, don't mistake my words to mean that
trees make their own food, they do not. Soil biota takes plant litter
and turns it into a form which gives rise to uptake by root hairs.
Fungal mat is something which extends this area beyond the drip line
making elements and water through capillary action available to the
root hairs. Still, it's the root hairs which are the uptake of a
tree, not mycorrhizae.
How does a fungal mat found IN soil do anything for an epiphyte?

When I find the statement about stinkweeds I will let you know. So I looked
So the Ganoderma tsugae is and epiphyte. But mycorrhizae, which is made up
of tree root and fungus tissues is actually part of the plant. It's a
composite organ. It does facilitate the taking in of phosphates. A lichen
would be a epiphyte.
See I do not have all the answers.
Here is a story on mycorrhizae.
