th. He said he would
rather have his walnut trees come from the northern route trees than the
southern.
PROFESSOR SMITH: Any one who has a good tree ought to write to our
secretary. I hope everybody will report these trees. The information
will be published in bulletin form and sent out to every member of the
Association. I fully believe that this information gathered and
disseminated will greatly assist in developing the walnut industry in
the eastern part of the United States.
MR. FROST: Mr. Pomeroy said that the pruning might be done at any time
of the year. I pruned a walnut tree one spring and it very nearly bled
to death.
MR. POMEROY: It seems to me that I have always pruned at any time. It
might be that when the sap is just nicely started--just before the tree
starts and the buds swell--it might not be wise to do that. I suppose
that the nut trees might bleed then the same as grape vines and certain
other plants and trees. I thought it never did any harm.
MR. FROST: It very nearly killed mine. They were big trees, too.
THE CHAIRMAN: I had just such an experience as that with grape vines. We
found that if grapes are pruned at a certain time in the spring they
will bleed profusely, and sometimes actually bleed to death. I never had
any experience with walnuts, but with vines we prune in the fall just as
soon as they are dormant. At that time the energies of the plant are at
a minimum and you can prune more safely than at any other time. As we go
on toward spring the moisture becomes greater and the sap starts, so if
you prune late in the spring there is great danger of injury to all
plants. If you prune in the fall you have no trouble.
MR. WILE: I would like to know if any one has had experience with
California varieties here in the East.
PROFESSOR VAN DEMAN: Professor Close has had more than any one else. I
have also heard of some in Florida.
PROFESSOR LAKE: We have had three years' experience; we have had also
the experience of others who have had them a longer time than that. Some
three years ago we grafted a number of California varieties on the
eastern black. In view of the eastern conditions, these are all making
splendid growth--some of them made a three-foot growth last year, some a
five and one-half foot growth this year. They went through last winter
splendidly; they are holding back finely in the spring and we had no
trouble with spring frosts on the grafted portions, even though many of
