walnut transplanting

Dear Alipine members

Thank you for your kind information on transplanting
walnut. This was in response to an inquiry to our
discussion forum at

The following is a copy of the original posting
and an important reply.

Hello Joel
Thanks for your speedy reply to my request for a free sample and additional
information on Rhizopon. I have a particular application, namely improving
survival of rooted walnut cuttings. After much trial and error we have been
able to obtain decent rooting in several genotypes of walnut rootstocks.
The difficulty we face is that the rooted cuttings do very poorly when
transferred to the field and many die. I think that it has something to do
with poor root growth and wanted to try to get the roots growing quickly
after transplantation. I believe that it would be worthwhile to try
Rhizopon. The walnut industry has been looking for a method to produce
clonal rootstocks for quite some time now and it seems a shame that we have
gotten this far only to be disappointed at the end. I do not know which
concentration of Rhizoponw would be best. In general walnut is difficult to
propagate and we have been using 6000 - 8000 ppm IBA for rooting. Perhaps
this will give you an idea of what concentration would be the best to try out.
Thanks for your assistance.
Sincerely,

Dear Ellen,
We received your e-mail on walnut through our importer for the RHIZOPON
products in the USA, Hortus USA.
Transplanting of rooted cuttings are more easy when you stick your cuttings
in plugs or small pots (containers).
To get a better result in rooting walnut cuttings we advice you to plant
the cuttings you have now available in a 10 liter container. These plants
will be your mother plants. Connect them to water and a fertilizing unit
with drip-irrigation. 
When the cuttings start re-rooting and the new growth starts you take out
the apical point. Now the plant will start making new young shoots. 
When these shoots are hard enough you can take them as cuttings and root
them in a paperpot of other small container. 
Use Rhizopon #2 or Rhizopon #3. 
Harvest the cuttings from the motherplants constantly never let them grow
to old. 
We hope that we give you a new stimulation for your research. 
Please keep us informed on your research.
