planting trees any deeper than they grew in the nursery.
I prefer to plant them a little deeper, say two inches or so. I do not
recall losing any trees seemingly from this slightly deeper planting,
while I did lose a considerable number of seedlings last year that were
inadvertently planted two inches or so too shallow.
Outside of the hickory I have had little trouble in transplanting any
trees excepting some of the hazels. Unless hazels, particularly American
hazels, are very well rooted, they will need more care the first year
than most nut trees, particularly protection from the hot sun and
drought. If I get poorly rooted hazels I now plant them in a shady place
for a year or two if they have not grown well the first year, and then
move them where they are to stay.
THE PRESIDENT: Mr. Snyder of Center Point advocates planting trees two
to four inches deeper.
DR. MORRIS: In Dr. Brooks' paper he spoke of some of the twig girdlers
in the beetle stage which feed upon the bark of twigs before
ovipositing, and he said that gives a weak point where we may attack
them. On my place at Stamford, where there are forests, that would be
impossible. I have had a good many hazels partially destroyed this year
by girdlers. A great many of the branches have the larvae in them. I
find also a large number of small hazels on which the leaves and
branches are dying, though there is no apparent injury to the bark.
Suddenly, however, a little twig will drop off and yet, in cutting into
them, I did not find any larvae.
DR. BROOKS: That happens to be the work of an insect which I am just
beginning to study, one of the flat-headed borers, and the reason you
have not seen the larva is that it is very small. It is not half an inch
long. In the second year it comes out as an adult. I judge that control
measures should be used in the spring, when I think without doubt that
it would feed on the poisoned spray.
DR. MORRIS: I find a great many larvae in dead twigs on the ground. If
we are going to get this pest out of the way, we should not only look at
the twigs on the tree, but at those on the ground as well.
DR. BROOKS: That is true of all of these curculios. Dr. Morris'
statement is true. The ground should be gone over and the dead and dying
branches and twigs of the trees should be collected. The insects mature
in them.
DR. COLLINS: Would you advocate pruning often?
DR. BROOKS: No.
