HIGH-DENSITY APPLE ORCHARDS MANAGEMENTThe use of smaller than standard sized trees of uniform shape in high-density plantings of from 200 to 500 or more trees per acre may be a solution to the problem of developing more efficient orchard operations. Trees in these plantings will require some type of size control, which can be accomplished in many ways a high density orchard is defined as any orchard with more than 150- 180 trees per acre. However, many highly productive commercial orchards today have 150-180 trees per acre and higher density could be anything over 180 trees per acre. For the purposes of this publication, there are several characteristics in addition to tree number that are included in a high density orchard system. Besides having an increased number of trees per acre, a high density orchard must come into bearing within 2-3 years after planting. To achieve this early production, it is essential to use a precocious dwarfing rootstock. Although it is possible to restrict the growth of trees on semi-dwarf rootstocks, they do not have the genetic capacity for early bearing. Consistent early fruit production is essential to offset the increased establishment costs. It is also very costly to hold trees on more vigorous rootstocks in an allotted space required for a high density orchard. To maximize the production of a high density orchard, it is also necessary to modify the training system and training and pruning techniques from traditional methods. Since trees will be bearing fruit early, a permanent tree support system is also required. It is essential to crop trees very early in the life of the orchard to offset the costs of establishment and to aid in managing vegetative growth. Early production is directly related to the number of trees planted per acre.

High-density supported apple orchards require a high investment and detailed management practices, with high risks of failure if proper procedures are not followed. However, the rewards are also high in terms of yield and quantity of apples. This report summarizes the main process required to establish a high-density supported apple orchard in Ontario. Chapters of the report cover site selection, soil drainage and type, soil nutrient levels and pH, nematodes, irrigation, frost protection, nursery tree quality and sources, planting, rootstocks, cultivar selection, pollination, supported-tree training systems, orchard establishment, pest control, and sod covers.

A book that became an instant classic when it first appeared in 1995, Old Southern Apples is an indispensable reference for fruit lovers everywhere, especially those who live in the southern United States. Out of print for several years, this newly revised and expanded edition now features descriptions of some 1,800 apple varieties that either originated in the South or were widely grown there before 1928. Author Lee Calhoun was one of the foremost figures in apple conservation in America. This masterwork reflects his knowledge and personal experience over more than thirty years, as he sought out and grew hundreds of classic apples, including both legendary varieties (like Nickajack and Magnum Bonum) and little-known ones (like Buff and Cullasaga). Representing our common orchard heritage, many of these apples are today at risk of disappearing from our national table. Illustrated with more than 120 color images of classic apples from the National Agricultural Library’s collection of watercolor paintings, Old Southern Apples is a fascinating and beautiful reference and gift book. In addition to A-to-Z descriptions of apple varieties, both extant and extinct, Calhoun provides a brief history of apple culture in the South, and includes practical information on growing apples and on their traditional uses.
