I'm Larry Dodson, a member of CRFG - Inland Chapter in Riverside.

On a trip to Vietnam in 1997 I tasted pitaya fruit for the first time
and it was love at first bite.  A couple of years ago, in Mexico I
saw large pitaya fruit at a supermarket in Saltillo.  They were
selling for 60 pesos each!  (Over $6 US)  I have several plants that
I started from Vietnamese seeds.  Never having seen pitaya plants, I
really did not know how to train or prune my plants.  On a trip to
Guatemala two years ago, I saw pitayas growing wild in the jungle
clinging to trees.  Thanks to Leo Manuel, I now have some good tips
on how to treat my plants.  Hopefully I'll get my first fruit this
year.  I'm looking forward to hearing about the experiences of others.

This past week the temperature has dipped below freezing at least
three nights, and it has been in the 30s the last few nights.  So far
none of my pitayas are showing any signs of damage.

My wife and I are leaving for Mexico in a few days and I will check
out the markets to see if I can find any pitayas or other unusual
fruit.  What's the season for pitaya fruit?  Larry

Larry,

I registered 26 degrees on a thermometer at ground level about a week ago and
my plants still seem ok.  My neighbor said there was even snow on the ground
one morning.  Sometimes the damage takes a couple of weeks to show up.
Surprisingly almost all of my plants look fine, of course the shade cloth
helps a little.  The fact that we had cold weather for several weeks before
the freeze and rain a few days before probably helped the plants survive the
freeze better than if it had been warm and dry before hand.

The season, at least here in Southern California, is July through September.
I would assume it is similar in Mexico.   Have a good trip.

Regards,
Sven

Subject: Seeds of Pitaya - How Much Light?

Hi

I have a few seeds that I really want to sprout, from a
hybrid of H. polyrhizus x epiphyllum (epiphyllum was pollen
donor.)  They haven't sprouted, but look normal.

I usually don't pay attention to whether the seeds are covered
with planting medium (sand or whatever.)  Is it your experience
that it's best to cover them, probably very lightly?  Would you
put them in a darkened part of a hotbed or not?

They're probably sterile, but look plump.  I haven't tried to
sprout seeds of H. polyrhizus before.  They are significantly
larger than seeds of H. undatus.  Maybe H. polyrhizus seeds
just take longer?

Take care,

Leo Manuel

Hi Sainarong,

Apparently messages can't have non-text attachments, so we have a
choice of your putting the pictures in the Photos section, or attaching
them to an email to me (mailto:rarefruit@...) and I'll put them
there.  If our space allotment gets used up, we may have to remove some
photos later.

I know we'd all like to see them.

Hi Leo,

I've never had a problem sprouting them even when buried fairly deep for the
size of the seed in those peat pellets.  They were always covered with soil.
I don't remember H. polyrhizus seed taking any longer to sprout.

I believe you can post pictures directly to the photo section, but if
you prefer, you may attach pictures to emails directed to me
mailto:rarefruit@... and I will upload them.

It seems that the photo appears in three sizes. The thumbnail view - to
whet your appetite. Click on it to get an expanded view.  Click again
to get the maximum size that is possible for it, as it was uploaded.

Keep checking on the "Files" section, as there are relatively newly-
uploaded files there, and more are enroute.

When we get close to our maximum alloted (30 MB) I will have to delete
some of the older files and/or photos, so keep current and download any
you want to have on your computer.

Make suggestions you think will improve the newsgroup, and we'll poll
the group to see if the majority goes along.

Take care,

Leo Manuel

Hi Sainarong,

I am glad you sent the Pitaya-in-Thailand picture.

Do the pitayas there stay in the pots, or are they planted in
the soil at some point?

Is it bamboo in the center for support?

On the PitayaFruit newsgroup, there is a column with odds and
ends of things mentioned, such as "Files" and "Photos" and (I
don't remember what all.)  If I click on "Photos" I get that
section, and if I click on some album, I have an option to upload
a photo.

Now, I, as moderator, and also using a Macintosh computer, may
not see what you see, nor have the same options, but if you have
a problem, I don't mind uploading for you.  I would be bothered,
though, if you couldn't see what has been put there.

Take care, and thanks again!

Sincerely,

Leo Manuel

Hi Sainarong,

I am puzzled.  The Group Settings has it so members can download,
access, or upload photos and files.  The only thing I can think of is
that perhaps you don't have a Yahoo I.D. (You and one other member) but
I know at least some other members have downloaded some files.

I would like to hear from other members to determine whether they can
view and download photos and files.  If not, it's a serious problem.

I don't know what else to try, at this time.

Sincerely,

Leo

Sainarong answers:

The pitayas in pots, when they become fully grown, are for sale as house
ornamental trees. I do not think the buyers ever plant them in the soil.
Yes, the pole is for support, but it is not a bamboo pole, it is a hollow
concrete tube. Bamboo would rot very fast in such conditions.

Last week I bought a yellow pitahaya. I collected some
of the seeds and now I was wondering if it is possible
to know the name of it? On the internet I see several
names for it: Hylocereus triangularis, H. monacanthus,
Selenicereus megalanthus, Cereus sp. ...
This is a picture of the fruit I found on the

Hi Pieter,

The picture looks like fruit from Selenicereus megalanthus.  I haven't
had the pleasure of seeing nor eating one, but two years ago I began to
grow some, and some of the plants are now five feet or more tall.  I
understand that seedlings take longer to begin to bear than plants
grown as cuttings.

Try searching for selenicereus megalanthus in Google -
http://google.com/search?hl=en&q=selenicereus+megalanthus
and you get a lot of leads.

Welcome to the group!

By the way, all of us are new to this group that was started last
month.

Subject: RE: Sweet Pitaya
Date: Sat, 12 May 2001 10:56:05 +0800
From: "Chung-Ruey Yen" <yencr@...>


Dear Leo:

Thank you for your interest in the pitaya in Taiwan. All of the cacti
cultivated in Taiwan are introduced from Central America and Vietnam.
The
area of pitaya may be up to 2000 hectares by now. I collected about 8
clones
of white flesh and more than 40 clones of red flesh. Most of clones
collected locally are hybridized among white and red flesh that were
introduced
from different areas.

We have transfered self compatibility from white to red-fleshed
varieties.
So some red clones do set fruits well without artificial pollination. I
agree that we have some clones with more than 22 of Brix. However, the
sweetness is only like about 12. It is only a liitle sweeter than
watermelon. The reason is that we measure only soluble solid contents
by
refractometer. However, there are some other contents included besides
glucose and fructose. There is no sucrose in pitaya fruit. Our
experience
indicate that more manures and potassium and phosphate also increase
the
sweetness in the fruit. So the pitaya produced locally in Taiwan is
well
accepted in the market, (as compared those inported).

Best regards,

Yen

branches of dying trees in clearings where the lush vegetation  had been
stripped away.   Larry Dodson

First, let me say that I am a complete novice in pitaya. What I know about
pitaya is what I have read and what I have seen at various orchards in Thailand.
My practical hand-on experience in pitaya is pitifully limited.

What you, Larry, say is most interesting to me. However, all pitayas I have seen
in Thailand are grown in full sunlight and they certainly look in full health. I
have read that the pitayas, growing wild in Thailand on branches of dying trees
(the writer assumes that the trees were dying because the pitayas were sucking
the life-giving sap out of them), were in poor condition and the fruits thereof
were awful, which is the reason why the Thais were unaware of the deliciousness
of the pitiya fruit until recently.

Do you, Larry or anyone else, have any explanation or experience you might care
to share? I, for one, am very interested.

The only explanation I can think of is that pitaya, grown wild and clinging to
host trees, do not get sufficient nutrients and are in poor conditions. As a
result, the wild pitayas respond poorly to strong sunlight. In contrast, the
pitayas, grown commercially in Thailand, are well-fed and healthy; and find
strong sunlight beneficial. Does this make any sense?
Enjoy Yourselves!

I think it depends on the variety.  There is no doubt in my mind that here in
Southern California they look greener and healthier when under a little shade.
There are lots of plants around that are grown in full sun without too much
difficulty.  Too much shade and they will not flower as much which can be a
problem.  The Asian varieties seem to be able to handle the sun a little better
than the others I have collected from California.

Sven

I was at a rare fruit growers meeting in San Diego this past winter and
someone was passing around a pitaya fruit that was sweet, juicy and beet red
inside.

I would like to get a cutting of that plant, so If you can spare one, please
let me know how much. I live in Vista.

I would imagine that most people in this group are interested in the pitaya
fruits. They want to know about the varieties which are tasty; they also want to
get hold of the seeds or the cuttings and grow them.
Some may even want to try their hand at cross-pollination, and produce new
varieties.
Where can we get our hands on the information on the interesting varieties, the
seeds and/or cutting thereof? Is there a data base on the Net? If there isn't,
then there should be one. Volunteer, anyone?
Eagerly awaiting for your advice/knowledge.
Enjoy Yourselves!
Sainarong

In the Cacti_etc newsletter someone wrote to say that at cactus-books
http://www.cactus-books.com you can order books on any topic.  The
result will be a search of sources and the prices may be significantly
less than the list price.
