Walnut Growing in Oregon
LOCATIONS FOR ADDITIONAL GROVES
Much is heard, in a general way, of necessary climate and soil conditions for walnut culture, some giving preference to the hillsides, others to valley lands; some contending for a deep, rich loam, others for sandy soil. But a careful examination of the soils of Oregon and the trees now bearing thereon produces convincing evidence that almost any deep, rich, well-drained, western Oregon soil--and some in eastern Oregon--not underlaid by hardpan, will insure a good harvest, providing the right varieties are planted. The whole question resolves itself into a matter of intelligent choice of trees to suit varying conditions.
For example, the famous Prince grove is producing magnificent crops on soil decidedly clayey; but the place is thoroughly cultivated and careful selection has been made of hardy trees, the Mayette being preferred.
