Northern Nut Growers Association Report of the Proceedings at the Eleventh Annual Meeting: Washington, D. C. October 7 and 8, 1920

Scions of nut trees for grafting should be handled carefully to avoid
rubbing off the buds, although this is not so important with nut trees
as with fruit trees, for the reason that the more important nut trees
such as the various walnuts, pecan and hickories have compound buds and
if the larger buds should be destroyed the secondary buds may be counted
upon to grow. The scions should be tied in bunches of a convenient size
to handle and, after being well tied and carefully labeled, should be
packed in paper lined boxes that will prevent evaporation of moisture in
the parking material. Any material that will absorb and hold moisture
and that will not heat when bulked, will answer the purpose for packing
scions, but we have found sphagnum moss to be the best material for this
purpose. This material can be obtained from the local florists or
dealers in cut flowers usually. Sphagnum will absorb a good deal of
moisture without actually becoming wet and will also hold this moisture
and give it off more slowly than any other packing material with which I
am familiar. This is especially important in keeping scions of nut trees
in good condition for grafting, because, if packed too damp, the scions
are soon spoiled for grafting, even if kept at a low temperature.
As a precaution against fungi, we usually use bordeaux mixture, two
thirds standard strength, to dampen moss for packing scions, especially
if they are to remain in storage several months.
Our rule is to use moss only slightly damp to the touch and if used in
sufficient quantity, say two or three times as much bulk as we have of
scions, we find no trouble in keeping scions in perfect condition for
months. In fact, as an experiment, we have carried pecan scions in cold
storage and without re-packing for fifteen months and then get a fair
stand of grafts to grow.
We usually advise putting scions in cold storage where convenient,
especially if they are for use in late May or June, but this is not at
all necessary if the scions are packed in moss only slightly damp. In
fact scions kept in an ordinary cellar at a temperature around 50
degrees have given us better results on the average the past two years
than have those from cold storage.

AFTERNOON SESSION, FRIDAY, OCTOBER 8, 1920, 2 P. M.
THE PRESIDENT: We very fortunately have with us a gentleman from the
Bureau of Entomology, Mr. F. E. Brooks, who will talk to us about nut
insects for a time and we will be very glad to listen to him.
MR. BROOKS: I believe your program is full for this afternoon and I
shall keep you but a few minutes.
