One Thousand Questions in California Agriculture Answered
Wickson, Edward J. (Edward James)
Agriculture -- California
There has been no demonstration that the Eastern black walnut is more
suitable to low moist lands than the California black walnut. Our
grandest California black walnut trees are situated on low moist lands.
Walnut Grove is on the edge of the Sacramento river with immense trees
growing almost on the water's edge. Walnut Creek in Contra Costa county
is also named from large walnut trees on the creek bank land. We have
very few Eastern black walnut trees in California and although they do
show appreciation of moist land, they are not in any respect better than
the Californian.
Ripening of Walnuts.
I send you two walnuts. I am in doubt if they will mature.
The nuts are well grown, the kernel fully formed in every respect.
Whether they will attain perfect maturity must be determined by an
observation of the fact and cannot be theoretically predicated. Where
trees are in such an ever-growing climate as you seem to have, they must
apparently take a suggestion that the time has arrived for maturity from
the drying of the soil. The roots should know that it is time for them
to stop working so that the foliage may yellow and the nuts mature. It
is possible that stopping cultivation a little earlier in the season may
be necessary to accomplish this purpose.
Cutting Below Dead Wood.
I have some seedling English walnut trees which are two years old, but
they are not coming out in bud this year. They are about three feet
high, and from the top down to about 10 inches of the ground the limbs
are dark brown, and below that they are a nice green. I cut the top off
of one of them to see what is the matter that they do not leaf out, and
I found that there is a round hole right down through the center of the
tree down to the green part. The hole is about three-sixteenths of an
inch in diameter. The pith of the limbs has been eaten away by some kind
of a worm from the inside. Would it be better to cut the tree down to
the green part, or let them alone?
It is the work of a borer. Cut down to live wood and paint over the
wound or wax it. Protect the pith until the bark grows over it or you
will have decay inside. If buds do not start on the trunk, take a sucker
from below to make a tree of. You could put a bud in the trunk, but it
is not very easy to do it.
Walnuts in Alfalfa.
Will the walnut trees be injured in any way by irrigating them at the
same time and manner as the alfalfa - that is, by flooding the land
between the checks? Will the walnuts make as good a growth when planted
in the alfalfa, and the ground cultivated two or three feet around the
tree, as though the alfalfa was entirely removed? Is it advisable to
plant the trees on the checks rather than between the checks?
