This year at River Falls, Wisconsin, which is only 35 miles southeast of
St. Paul, Minnesota, the season started off with much rain and a delayed
cold spring. All the grafting had to be postponed from two to four weeks
later than normal. The stored scion wood suffered some because of this
long storage period, and some of it was quite dry when taken out. This
was particularly true of the Weschcke butternut and these scions looked
so dry that I was tempted to throw them all away, but instead I gave
them to two young horticulture students to practice with. None of them
grew, however, so we had a 100% failure on butternut grafting. About a
dozen years ago I had much success grafting butternut on black walnuts
and was unimpressed, therefore I did not make any notes as to the
process I used. This was a mistake for apparently I have lost the art.
The last five years has probably produced only about five or six plants
successfully grafted on black walnut. Hickories respond much better and
I usually get about 50% successful grafts on my native butternut stocks.
Although the insect pests, such as the butternut curculio, were delayed
in their attacks, they eventually caught up and destroyed most of the
big butternut crop and did their usual damage to heartnut and Persian
walnut growth. I noticed in the American Fruit Grower that plum curculio
was controlled in the peach orchards through the use of hexaethyl
tetraphosphate. If this chemical poison controls plum curculio, it ought
to control any of the curculio family, such as the hazel curculio,
chestnut curculio and butternut curculio. The butternut and hazel
curculio appear to me to be the same insect. I am not troubled with the
chestnut curculio yet, but if this chemical gives control over the
curculio insect family we will certainly be able to raise large crops of
all of the nuts mentioned.
Quite a few of my grafted test trees, both in the forest and in the
orchard, which in some cases were grafted on bitternut hickory stocks
fifteen years ago, are beginning to bear. These varieties are the Woods,
Fox, Taylor, Platman and Davis. Others which have borne a few times
previously also have good crops set. These are Bridgewater, Glover,
Beaver, Kirtland, Deveaux and Fairbanks. The trees setting the largest
crops of hickory nuts are the Weschcke, and they are the only ones that
I can really count on maturing early enough to escape our usual early
fall frosts.
I derive great pleasure in observing new seedling plants of filberts,
hazels and their hybrids coming into bearing for the first time this
year. There are about two hundred of these new varieties. Of course most
of them will be worthless commercially. The ideal hybrid hazilbert has
not yet appeared, but when it does we will propagate it for sale as
rapidly as possible.
At this date, August 20, we have suffered from an extremely dry August
and will apparently lose many trees that we cannot reach by irrigation
or some other means of watering.
