The best way for planting in the orchard is to bore a hole with a post or well auger 4 or 5 feet deep where the tree is to grow, put in a stick of dynamite and break up the ground thoroughly.
Or, better still, bore down to permanent moisture and fill the lower hole with good soil or other root food, then dynamite 4 or 5 feet of the upper section of the hole. Nothing will produce a vigorous and thrifty tree like a deep and vigorous root system, and no tree responds to cultivation and care as does the walnut, white or black. After bursting up the soil, excavate and put in a half bushel of barn or other mould, well rotted. This will force the tree in the earlier years of its life and can be no hindrance to it later. Cover the manure with a foot or two of soil and plant. Both before and after planting the ground should be ploughed and harrowed until it is as mellow as an ash heap. Plant three or four nuts in a hill 6 to 8 inches apart and at the end of the first season's growth pull out all but the most vigorous one. For transplanting from the nursery the same methods should be followed in the preparation of the hole and the soil as in planting the seed nuts. If one wants to lay the foundation for a fine orchard and a fine fortune as a consequence, these preliminary steps must not be neglected. Because in time you expect this tree to pay you a rental of $8 to $12 a month. If you are building a cottage that would bring in that sum, you would put in much more work and money besides. The wise grower would rather have a man plant six trees for him in one day than sixty. The walnut is usually a very vigorous tree and will fight its way among adverse conditions and surroundings, but its golden showers are much more abundant if it is protected from the scars of battle, especially in its youth. It almost seems to respond to the love and affection given to it by a kind master. Animals respond to kindness, and why not the domestic trees? It will pay you a big salary after a while when your other bank accounts and your health and strength fail.
American Black Walnuts
A magnificent row of nine American black walnuts, 35 or 40 years old. The tree in the foreground is 20 inches in diameter of trunk. The tallest of the trees is nearly 60 feet and they have a spread of more than 70 feet. They are at the residence of Dave Johnson on the Portland road about 8 miles from McMinnville. Seed from such trees as these would produce the very best trees for grafting upon.
There are very few California blacks of pure strain in the country. The hybrids or crosses with the American or eastern black walnut, are better trees for grafting stock than the pure Californias. They are more hardy and better adapted to our climate.
