One hundred and ten years ago serious research and plant development were the norm, with great rewards possible from successful new planting varieties. The USDA yearbooks published a series of articles showcasing what they called “Promising New Fruits.” If any of these survive today they likely might be seen as heirloom varieties. – SFJ
Fruit trees should always be planted in a sunny location. Full sun encourages vigorous growth, while discouraging fungal disease. A minimum of six hours of sun is requisite. Avoid planting near the edge of a woods, which may seem sunny, but allows little direct light. Also, choose a site that has good, but not excessive, air flow. Upland slopes that run perpendicular to prevailing winds are the ideal. Valleys often have troublesome frost pockets; hilltops expose trees to temperature extremes and drying winds.
