_Soil Requirements_
The Japanese walnut seems to thrive on many soil types ranging from a
heavy clay to a light sand, but does best on what is popularly known as
a well drained fertile sandy loam with a friable clay subsoil. It will
not do well on strongly acid soils and those who have planted trees on
such soils should apply lime in liberal quantities. Poorly drained soils
or very light soils deficient in humus are also not suitable.
_Tree and Nut Characteristics_
The Japanese walnut has several characteristics which make it desirable
as an ornamental and as a nut-bearing tree. It grows rapidly, has large
numerous luxuriant leaves which give it a tropical effect, and usually
has a symmetrical outline. It bears early, sometimes in the second year
from the graft, yields heavily and is often reported to yield regularly.
A heartnut tree owned by Mr. Sylvestor Kratz of Jordan Station, Ontario,
produced nearly seven bushels of husked nuts one season and Mr. J. W.
Hershey reports a yield of ten bushels of heartnuts from a tree near
Olney, Pennsylvania. He also reports a cash return of $50.00 from one
tree grown by Mr. Killen of Felton, Delaware. These were heartnuts and
sold for 50 to 75 cents a pound. Mr. J. V. Gellatly, Westbank, B. C.,
obtained a yield of ten bushels of unhusked nuts from a heartnut tree of
medium size. The yields from the common type, J. sieboldiana, have also
been heavy, but since no figures are available no definite statements
can be made.
In the Japanese walnut as in other species of nuts there is marked
variation in nut characteristics, such as size, thickness of shell,
cracking quality, extraction quality and flavor of kernel. Heartnuts
have been found ranging from 1/2 in. to 1-3/4 in. in length. The largest
heartnut I have ever seen came from Gellatly Brothers of Westbank, B. C.
This nut was 1-3/4 in. long by 1-1/4 in. wide and was fully 1 in. thick.
I also located a fine Sieboldiana type which is said to be the largest
found up to date. (See specimens in jars).
Some of these good kinds possess excellent cracking and extraction
quality. Mr. John Hershey of Downingtown, Pa., reports several good
easy-cracking strains not yet introduced and Mr. Gellatly has one called
O. K. that can easily be cracked with a hand nut cracker. I have also
found one that I believe is a hybrid and which has excellent cracking
and extractio
