Great link!

I've been looking something like this already everywhere.

Thank you!

Gruss Stephan

the following Einordung.
a. dunnii
: heavier, well draining group I store in soil South east China

I have read also different and not so practise I.

On demand for snow, I got the answer are no own experience, but has been collected from various sources.
The terms A. dunnii was unfortunately not changed.

Just got the Aroid journal not at hand, not what it says there?

What do you mean?

Hallo Amorphophallusfans,

in der aroid-L hat Wilbert Hetterscheid aka Lord P. auf eine Frage zur Lagerung von Amorphophallusknollen die unten zitierte Antwort geeschrieben.

Sie enthält Angaben, mit denen zum Teil die Empfehlungen im Vol. 19 der Zeitschrift Aroideana korregiert werden.

Zur Übersetzung kann der Babelfisch bemüht werden:

Zitat:
"Hi John and other peoples,

I cannot confirm your observation. In fact I have noticed quite the
opposite. In my collection, the ones that need continuous soil and/or
watering always have roots spread all over the tuber that usually are
healthy when the leaf has already died down. The ones that need dry
conditions and have lost their leaves, are usually also without roots or
have dead or dying roots.

My experience and that of others written to me, have changed my views on
dormancy issues in Amorphophallus quite dramatically over the years since my
publication with Ittenbach in Vol. 19 of Aroideana.

Generally it seems that species from (West-)Central Africa, West Malaysia,
Borneo, Java, Sumatra, S. & SE China and N. Vietnam need to be kept in soil
all the time. They tend to have rather short dormancies or nearly none at
all. They are from very wet areas (everwet tropical). During growth they can
hardly be "overloaded" with water during watergift. Species for which this
works good are:

angolensis
angulatus
annulifer
bangkokensis
baumannii
beccarii
borneensis
boyceanus
brachyphyllus
bufo
coaetaneus
costatus
croatii
decus-silvae
discophorus
dzuii
eburneus
eichleri
elegans
excentricus (is also quite drought resistant)
galbra
gigas
glossophyllus (also quite drought resistant)
hayi
hetterscheidii
hewittii
hirsutus
hottae
infundibuliformis
interruptus (also quite drought resistant)
julaihii
koratensis (when young)
lambii
manta
myosuroides
ochroleucus
opertus
palawanensis (can also be stored dry)
pendulus
prainii
preussii
rhizomatosus
rugosus
sagittarius
scaber (only when young)
sinuatus
sparsiflorus
spectabilis
staudtii
subpedatus
tinekeae
titanum
tonkinensis
tuberculatus
venustus
verticillatus
zenkeri

Unfortunately, this behaviour makes them the more difficult species to grow
(except the ones from N. Vietnam, S. & SE China and A. hottae). The ones
that have a prolongued dormancy are usually the stronger ones in cultivation
and need less humid conditions.

Then the smallest of species also appreciate not to be bone dry but they
must also be watered carefully and not become too wet. They too tend to have
hardly any appreciable dormancy and flower immediately after leaf shed or
alongside mature leaves:

myosuroides
obscurus
ongsakulii
polyanthus
pusillus
serrulatus

I think Tony Avent and Alan galloway may have plans to pubblish on this. In
case the IAS board decides to reprint vol. 19, I will add a text on this
subject as introduction.

Of course it may be that under local circumstances at individual people's
places, plants may have a deviating behaviour. But this is merely a general
directive.

Cheerio,
Wilbert"

Hello

very interesting and helpful, the description of the conditions of winter rest of Amorphophallus by Wilbert Hetterscheid.

Especially the with the roots during the rest period, seems very logical.

With kind regards
Stefan

Alsoooo...


I think Tony Avent and Allan Galloway have plans to publish this.
Possibly, the IAS will decide even once again to print the No. 14.
I will then add this text to the topic.

Of course, it is possible that the plants behave differently in other conditions, because this is only General in nature



The translation of various Internet providers is an imposition for not English may end because they individually translated every word.

With kind regards
Stefan

Beginning of the translation:

Hi John and others,.

I can not confirm your observation. In fact, I've noticed the opposite.
In my collection types that should be always in the substrate or should be kept always moist, have distributed roots on the whole bulb and this root are healthy normal way (yet) if the sheet is indented already.
The species that need dry conditions (during the rest period), have no roots (spread over the CORM) or the roots are dead or die just off when the tide pulls up.

My experience and others have my opinion on the subject?Calm? in Amorphophallus 19 of the Aroideana dramatically changed since the publication of with Ittenbach in the band.

It seems generally to be that species from (Western) Central Africa, West Malaysia, Borneo, Java, Sumatra, South and South East China and North Vietnam in the substrate must be kept so. You have a rather short or no resting phase. During the growth phase, they can be shed little. Species for which are:

angolensis, Angola Dentex....
..
zenkeri

Unfortunately this behavior makes more difficult in the culture (with the exception of those from North Vietnam, South and South East China and A. hottae).
Those with prolonged resting phase are usually more resistant in the culture and they need less humid conditions.

On the smaller species appreciate it not dry, it must be also slightly damp, without being kept too wet. She have also also often no notable resting phase and blossom immediately after the Blattfall, or in addition to a full blown sheet:

myosuroides
...
serrulatus
At the end of the translation.

Stefan has already made the rest...

Hope it is now clearer...

Bernhard.
P.S.: I love the Babel fish still; the translations are always to the laugh break
@ Erwin: Babbel fish is also nice: icon_biggrin:-LOL
Only to the info where it comes from:

But perhaps you have also read the fictional trilogy....

Hello

in continuation of this thread did I you ask how you stored your tubers during the winter?

This is me above all to those specimens that will be winters beyond the Earth, so those who have no roots in the rest period and come not from the immerfeuchten areas.

Sets up her open? Do they in boxes? At what temperature? What size stores you tubers dry outside of the Earth, because Yes, the risk of dehydration in too-small tubers?

What anyway always surprises me is that in nature also none excavates the tubers!

In any case in advance thanks for your experiences - I think that the question of multiple newcomers could be interesting!

Georg

Hi Georg,.

so I do rather natural it innder rule, that is, I'll let dry out all pots after withdrawing the tuber, which is to be winters dry. I am simply a casting...

If I have to watch from Neugriede, which has grown so the tubers are anschiließend again in the pot - substrate druff - ready (and no longer pour).

The pots remain (10-35 ° C, depending on the high-temperature environments) in the winter garden or komen in the cellar (it is estimated that approximately 13 ° C).

I have installed Konjac and albus also in pots without substrate over the winter.

Titanaum, hewittii and co be moderately moist (damp) substrate on the rest placed in, but if possible at temperatures > (15) 18 ° C.

Happy stroring,
Bernhard.

Hello Bernahrd,

I've got grad only 2 species from Thailand:

A. longituberorus and A. amygdaloides

Therefore I should that even pot a and the pots just dry and cool in the basement that, or?

Georg

Hi Georg,.

I care not of either type, but

Since longituberosus in West Malaysia and from the image ( http://aroid.org/genera/amorphophallus/l…)AM289Tubers.jpg) the root produced in the group belongs, which is to spend the rest in the substrate I would probably handle this type.
(Compare with the above-cited mail by Wilbert Hetterscheid...)
With the cool cellar, however, I would be careful...

I can think of to amygdaloides allow no opinion, but perhaps Christian aka RealTreder has it in his collection....

MfG,
Bernhard.

Hi Bernard and thanks for the Info!

Last question: what would you do atroviridis with A.?

Thank you

Georg

Hi Georg

atroviridis should be stored dry, at temperatures
15-20 ° c, I topfe it out and let it lie without substrate.

Greeting René

Hi Georg,.

I agree with René, but a special feature on the atroviridis I noticed: I the tubers have blossomed only after pot in moderately humid substrate. Already Austriebe have previously shown, but you wanted to grow not quite and have put off really only after the pot up properly. Also my muelleri wanted to not grow forever, until I have eingetopft them (then also she has pushed on vigorously).

I had the same phenomenon surprisingly also Typhonium venosum and most clearly at Synandrospadix vermitoxicus.

MfG Philipp

Hi Philip,.

now, I find it not so exceptional that the tuber only drives out, if it is in the Earth.

Think it was exactly the same: I hav it with ca 2-3cm long branches from Thailand get, then anything beyond the Earth leave. Only when she have used after a few weeks, the shoots have developed - but then vigorously!

Georg

Hi Georg,.

here in the Forum but circulating the opinion that all tubers that overwinters outside of the substrate should flourish outside of the substrate. Getopft is then only when evidenced by a significant new beads with root tips. With this method I came up pretty well so far, so I was a little baffled about the exceptions. But regardless, I've learned hold again what new;-)

MfG Philipp

So I can speak only about my experiences with A. Konjac.
At the beginning I they always properly excavated and placed in an old Obskiste on the (unisorlierten - cold) attic. In the spring, I have then looked after the tubers, and if were already shoots as I put it in Earth free provided for us by the manure square (meiener opinion, which is not much nutrients, but they have survived it;-)).
Since the tubers were becoming more and more I've managed no longer time to unearth all. Therefore have I simply stopped in the autumn as most have dropped even your hand Knllen to pour and have it easy in the attic and hibernates in the cellar (between 14 and 16 ° C) in the Earth. Since I no longer have dug out they I can not say whether there were losses but so how you should multiply the conditions match.
