The strawberry grower, after choosing a suitable site and preparing the soil carefully, should select varieties adapted to his district and needs. He should use plants that are disease-free. In California, southern Arizona, New Mexico, and Texas the plants should have undergone a rest period. Usually the growers plant during the period of greatest rainfall. By using the recommended systems of training and care before, during, and after setting of the plants and the suggested methods of decreasing diseases and insect pests, he should obtain better yields. A grower can furnish consumers a better product by using good methods of harvesting and shipment. He can prolong the fresh-fruit season only a little by the use of cold storage, but he can extend his market by …
