Buyers should be on their guard not to be deceived by flowery, but vague
descriptions. If catalogues list nut trees by recognized variety names
it is pretty safe to assume that the trees are as represented. If
recognized variety names are omitted the trees may safely be considered
to be seedlings and that they will produce a wholly unknown quantity,
no matter how alluring the advertising. Of course, this is not intended
to discourage the planting of new varieties offered by nurseries of
known reputation for integrity, nor of such strains as the Crath
Carpathian walnut importations, from which new varieties are emerging.
As a practical note I wish to state that the black walnut is by far the
most satisfactory stock on which to graft walnuts of any species. Not
infrequently seedling English walnut trees take from ten to fifteen or
more years to come into bearing. I have fruited fifteen or more
varieties by grafting on black stocks, and in no case has it required
more than five years for the trees to bear. Frequently they have borne
in two or three years. The English walnut is also a more vigorous grower
on black walnut roots than on its own.
The Sherwood butternut grafted five or six years ago on butternut stocks
has not borne yet; grafted on a small black walnut in the nursery row in
1942 it bore one nut in 1943 and has many staminate buds for 1944
visible at the present time. Walters heartnut bears the second or third
year on black walnut; it has not borne for me on butternut after seven
years. The same holds good for the other heartnuts.
In the grafting of chestnuts, defective (incompatible?) unions can
generally be spotted the first year. They develop with a transverse
fissure into which the bark ingrows. Good unions show new tissue
entirely around the closing wound; the final scar as healing approaches
completion being vertical, i. e. longitudinal with the stock. This
result can be obtained by proper technique.
The members of the Association can do much to further the cause of nut
tree planting by discrimination in recognizing the ear-marks of honest
advertising and encouraging their friends to make their purchases from
conscientious, responsible nurserymen. Our Association nursery list is a
valuable help in this direction.
