The only recommendations that can be made relative to planting the Persian walnut in Michigan are, that it be planted very cautiously in any part of the state and except under very favored circumstances it be not at all in the middle of the state. Do not undertake to grow the trees by planting the nuts or by buying seedlings. The most desirable trees are those of hardy varieties, budded on the black walnut as a stock a foot or more above ground. THE FILBERT The filbert has been one of our tantalizing species of nut trees. In England, trees grow to ages of from one to two hundred years, bearing profusely meanwhile. There, for many years, they are grown under apple trees with currants below them. In Germany, we are told that strawberries are grown below the currants and gooseberries. We are waiting for the Yankee who will be first to grow peanuts or potatoes below strawberries. In the eastern part of this country, plants of the European kinds are disappointing in two ways. First, they are uncertain as to their ability to bear; and second, they are highly susceptible to a fungus disease found everywhere that the native hazels abound. The native species is quite able to resist this disease, but the introductions ordinarily succumb to it quickly. In the Pacific Northwest, where by many filbert culture is believed destined to become a successful and paying industry within the next few years, not infrequently some varieties begin to blossom as early as in December. The blooming is largely responsible for the failure of eastern trees to set and mature crops of nuts. Several nurserymen are now endeavoring to find varieties of commercial value in the eastern part of the country. Apparently they are meeting with some success as far as their work has gone. Many of the varieties they are testing are proving inferior, but a few have borne good nuts in gratifying quantity for several years. During the past winter, a good many froze severely, although they are commonly hardy under severe weather. Wherever they are planted, they should have fertile soil, from 20 to 25 feet of space each way and should be trained to tree form. After 10 years or so, they should be headed back severely, unless regular pruning has been practiced in the meantime. Filberts fruit only on new wood.
