Persimmon trees provide a late-season harvest of sweet fruit and striking ornamental color. Determining the correct planting distance is the first step toward a healthy, productive tree, governed primarily by the species. The two main categories are the American persimmon (Diospyros virginiana) and the Asian persimmon (Diospyros kaki). Proper spacing is a fundamental requirement for long-term health, maximum fruit yield, and ease of management.
Biological Reasons for Proper Spacing
Adequate space ensures each tree receives the environmental resources required for optimal growth. Light penetration is a significant factor, as fruit production is directly tied to the amount of sunlight reaching the branches. Closely planted trees develop dense, shaded canopies where interior branches produce little or no fruit.
Spacing also promotes air circulation, which helps rapidly dry foliage and fruit surfaces. This significantly reduces the incidence of fungal diseases like leaf spot. Furthermore, proper distance prevents root systems from competing aggressively for limited soil nutrients and water. Minimizing this competition reduces stress and maximizes consistent growth and higher-quality fruit production.
Spacing Guidelines for Asian Persimmons
Asian persimmons (Diospyros kaki) are the most widely cultivated species for fruit production. Standard spacing recommendations range from 15 to 25 feet between trees, influenced by the rootstock used and the planned pruning system.
Trees grafted onto semi-dwarf rootstocks or those managed with heavy annual pruning can be planted 15 to 20 feet apart. For standard-sized trees, 20- to 25-foot spacing is necessary to prevent canopy overlap at maturity. The chosen training method also affects spacing; a modified central leader system encourages an upright shape and tolerates slightly closer planting than an open-vase system. When planting in rows, 20 feet between trees and 25 feet between rows is a common commercial practice for standard varieties.
Spacing Guidelines for American Persimmons
The native American persimmon (Diospyros virginiana) is a larger, more vigorous tree than the Asian species, requiring significantly wider spacing. These trees can reach mature heights of 35 to 60 feet and develop a wide, spreading canopy. Consequently, the standard planting distance ranges from 30 to 40 feet apart to ensure sufficient room for canopy development.
American persimmons have a tendency to sucker, sending up new shoots from the roots that can form dense thickets. Wide spacing helps isolate the desired trees and manage this habit. For fruit production, most American persimmons are dioecious, meaning male and female flowers are on separate trees. To ensure successful pollination and maximum yield, at least one male tree should be planted within 50 feet of female trees.
Adjusting Spacing for Intensive Planting and Pruning
Growers aiming to maximize yield in a limited area may opt for high-density planting. This method is primarily applied to Asian persimmons and requires a commitment to rigorous pruning and training. In high-density systems, trees may be planted as close as 10 to 12 feet apart, often utilizing specific rootstocks or varieties that naturally exhibit less vigor.
Closer spacing necessitates aggressive annual pruning, typically in late winter, to restrict the tree’s size and maintain a narrow canopy. This management is essential to prevent canopies from touching and compromising light penetration and air flow. Some commercial operations employ hedgerow systems, planting trees closely in the row (e.g., 8–10 feet) but with wider spacing between rows (e.g., 20–24 feet) to allow equipment access. This intensive approach trades the larger, individual tree production of standard spacing for a greater total yield per acre, but it requires a much higher level of ongoing management and labor.
