You who are interested in nut trees which thrive in the northern states, must recognize that two factors contribute to the development of superior strains. One is hybridizing and the other sport development. The former is a long term project which should have institutional backing. The opportunity for the latter, that is, chance development of a superior or unique variation, is in direct ratio to the number of nut trees growing in the area. Successful farm nut growers, dotted over the region, will, therefore, increase the chance that finer strains will appear.
But whether the farm nut grove ever abets science and produces the long sought superior nut, is of little importance compared to its value to the farm. It is incumbent, therefore, upon every nut enthusiast, who has a hand in bringing to the attention of farm owners the value of nut trees, to be meticulous in giving instructions for their planting and care.
Tree Crop and Nut Notes from Southern Pennsylvania
JOHN W. HERSHEY
Broadview English Walnut—This hardy variety seemed so good it took a lot of effort to keep from recommending it commercially. The oldest tree in our section, owned by my brother, bore lightly for several years. With its fine flavor, tree beauty and hardiness it edges closer and closer to where we can recommend it commercially. In its seventh year it bore a half bushel; the 8th, this year, it's really loaded. I have planted 30 trees.
A Southern Persian Walnut The northern man in the south loves the cool climate, Persian walnut. I have found chance seedlings here and there, even down to northern Alabama. One tree, northeast of Knoxville, Tennessee, had a good quality nut and was seemingly resistant to sun scald. Starting late in the spring it avoids the late frosts so damaging to horticulture in the south.
Cornell Black Walnut—This new variety, a Thomas seedling, named Cornell by its originator at Ithaca, New York, bore one nut for us in 1946. The boys at Cornell like it because it fills even in an abnormally cool season of the Finger Lakes region when natives fail. You can't decide an issue with one nut, but our specimen was as large and full of high-flavored, white meat as the Thomas, and as thin-shelled as the Stabler. So attractive does this variety appear that I am reserving it this fall in order to plant several in orchard form to produce scion wood.
Honey Locusts—The latest report on their performance comes from J. C. Moore, Soil Conservation Service at Auburn, Alabama, on February 3, 1947. Their laboratory tests of Millwood show a sugar content of 36.65%, and Calhoun 38.95%. The animal husbandry department of the Alabama Experiment Station at Auburn has found the pods equal to oats, pound for pound, in a dairy ration. A team of mules fed for 30 days on pods showed satisfactory results. Cows and hogs showed equal success. At 5 years of age, Millwood averages 58 pounds and Calhoun 26 pounds per year. At eight years, Millwood bore 200 pounds, and Calhoun 60. The pods fall from October 15th to December 30th. Lespedeza sericea planted between the trees yields 2½ tons per acre annually. This gives us courage to continue emphasizing their great value for pasture and rough land planting. The trees we planted in our swampy, worn-out meadow are doing fine.
Mulberries—This great chicken, bird and hog feed will some day fill a definite place in the sun of the American farmer, just as it does in Asia. The drawbacks are lack of hardiness and short bearing season in the north. The Hicks variety bears for six to eight weeks but is not hardy north of the Mason-Dixon line. This year we have grafted eight varieties of which seven are new. One from southern Indiana, an American seedling selected by a mulberry enthusiast, bears for six to eight weeks. Will it be hardy farther north? We shall know soon. Six are from select seedlings of L. K. Hostetter, of Lancaster, Pa., the mulberry king of America. The other is a fine white, a chance seedling from 75 miles north of Pittsburgh. It has not borne yet but was far hardier than Downing last winter. I have a few of these to sell this fall. Mulberries need sweet soil to prevent winter killing. On worn out soils we have discovered that they do well until established, by applying a few handfuls of lime around the tree at planting time. Not only are they excellent for the above mentioned uses but the right varieties are better than raisins when dried.
