From the Wisconsin Horticultural Society we obtained a pound of English
or Persian walnuts in 1937. So far we have some 23 seedlings struggling
to keep alive. They range in height from 18 inches to 7 feet and are
definitely out of their range. Some years they grow 4 feet of new wood
and some winters it all kills back. There seem to be differences in
hardiness and--who can tell?--they might even bear a nut some day. Bark
injury, which may be winter sun scald, has damaged some of the trees.
One tree of the Broadview selection is alive after four years and may
make a go of it.
Hickories grow wild in certain parts of Minnesota, but this doesn't
happen to be one of those parts. They seem to do best where soil is acid
in reaction and here we are amply supplied with lime. That may account
for the slow growth of a grafted Hales hickory tree. It was 3 years old
when set out in 1921. For the first 9 years it had just 2 leaves per
year. Now approaching 30, the tree is 7 to 8 feet high and going up at
the rate of 8 to 12 inches a year.
Nuts from Wisconsin, Michigan, and Minnesota wild hickories, have done
better. At 8 years the trees are from 1 to 2 feet high, with a couple of
Shakespeares, (geniuses) towering a foot above them. This may not be
hickory country, but, by gum, they're growing! A couple of years ago,
Dr. Brierley from the Central Station, Division of Horticulture, who has
nut propagation as one of his minor projects, gave us 7 seedlings of
shellbark hickory, (Carya laciniosa), from a tree planted many years ago
by Peter Gideon of Wealthy apple fame. After 2 winters, these 7
seedlings are still with us and seem to grow faster than the shagbarks
(ovata).
Other attempts to vary our diet (if we live long enough) are a few
Chinese chestnut seedlings. A couple secured from the Nut Tree
Nurseries, Downington, Pa., in 1940 are now 3 and 4 feet high and
apparently in a good state of health. They are leisurely growing, which
may be a good thing. Trees like the Manchurian walnut which grow 6 to 8
feet of new wood in a year, seem to freeze back and start over more
frequently than the trees which poke along but harden their wood before
cold weather. In 1946, a few more seedlings from D. C. Snyder, Center
Point, Iowa, were set out and most of them have survived the first
winter. Carl Weschcke reports that chestnuts do best for him at River
Falls, Wisconsin, in sandy soil with an acid reaction. If I ever raise a
chestnut, I'd like to send him one.
