Re: Potting Mix for Anthuriums?

For as many people as there are that grow Anthuriums, that is the number of
people that will have their own 'favorite' mix.  What will work under one
persons growing conditions will not or may not work under someone elses...
So, no one mix is bad and no one mix is good.  If it works, don't fix

If you stop to consider the way they grow in the jungle, this will give a
clue as to what they like.  In the jungle they grow as epiphytes on trees
with the roots entwined in the moss that also grows on the trees and in the
leaf litter that accumulates in the ferns and other epiphytes.  When they
grow on the ground, the roots are all in the leaf litter.  Never have I
seen roots in the clay soil that is predominate in the parts of the jungle
that I have visited.

Getting them to grow in 'artificial' conditions should reflect the way they
grow naturally.  I grow many of mine on totems that are three inches square
and four ft. high and is filled with sphagnum moss...   For more
information on this, see the IAS Newsletter of April-June1997.  I wrote an
article that described it in detail.

If you grow Anthuriums in a pot...  (and remember... when God invented
Anthuriums...  K-Mart was closed and he couldn't buy any pots....)  Just
remember that there has to be a lot of air exchange in the root area....  I
have seen Anthuriums growing in large chunks of pine bark with nothing else
in the pot...  They were growing beautifully but had to be watered at least
twice a day and fertilized with a weak solution at least once a week...
Now, the other end of the scale....  I use a media of 1/3 Canadian Peat
Moss, 1/3 Perlite and 1/3 composted pine bark in small chunks...  This
allows lots of air in the roots and is well drained...  Anthuriums do not
like "WET FEET', but they do like to be moist at all times...  If a plant
does not seem to like the above....  I will add a few styrofoam peanuts to
the mix....  this gets more air circulation to the roots...

Just remember that most all Anthuriums are epiphytes.  I have seen
Anthurium andreanum in the jungle with six to ten inch internodes that were
streaching for a tree on which to climb.  When they found that tree....  it
became a short compact plant....

I hope the above helps...

AND, for your convenience I am attaching some information on the IAS.
There are lots of good articles in back issues  of Aroideana that would be
very informative....  If you will privately send me your snail mail, I will
send you a booklet on the IAS.  (I will do the same for anyone reading


The International Aroid Society (IAS) was founded in June of 1977 at the
home of Bette Waterbury, who became the first President. Dr. Michael
Madison, Taxonomist at Marie Selby Botanical Garden in Sarasota, Florida
was the Guiding Presence and became the Editor of our Scientific Journal,
the Aroideana. The name was suggested by Dr. Dan Nicolson of the
Smithsonian Institution. It means 'having to do with or pertaining to
aroids.' The Society is dedicated to promoting the study of the aroid
family in all its aspects. Membership is open to anyone who has an interest
in this plant family.

The IAS has been a fast moving organization. By the end of the year, 1977,
there were already 73 members. This progress has continued. There are now
over four hundred members world wide and we continue to grow.

Publications: Aroideana is published one Volume per year and contains in
excess of one hundred pages. Sometimes it is published more than once
during the year and these additional Aroideanas are Numbered. Usually, the
number of pages totals about one hundred for the year. This publication is
devoted to the more scientific aspects of Araceae. The Newsletter is
published quarterly and is a more 'chatty' publication. Here,
announcements, general horticultural information, plant exchanges and new
Aroid Literature are discussed.
