Persimmon

Persimmon is grown as a long-lived, grafted deciduous tree in subtropical and mild-temperate growing regions. Once established, plantings can remain productive for many years, and the tree is generally considered adaptable and relatively pest-tolerant compared with many other tree fruits.

Commercial and dooryard production both draw on the astringent/non-astringent distinction, which shapes cultivar choice, harvest timing, and postharvest handling throughout the supply chain.

Family

Ebenaceae (ebony family)

Genus

Diospyros

Principal species

Diospyros kaki (Asian/Japanese persimmon)

Growth habit

Deciduous tree, commercially propagated by grafting a fruiting cultivar onto a selected rootstock

Astringent vs. non-astringent

A classic cultivar division based on natural tannin content: astringent types require full ripening/softening or postharvest treatment to be palatable, while non-astringent types can be eaten firm

Persimmon (Diospyros kaki) originates from East Asia, where it has a very long history of cultivation, and has since spread to other subtropical and mild-temperate fruit-growing regions worldwide.

Persimmon is a deciduous tree that requires a period of winter chilling to break dormancy and flower normally, similar to other temperate deciduous fruit trees, with the specific requirement varying by cultivar.

The tree is generally more cold-hardy than many evergreen subtropical fruits once dormant, but young growth and blossom remain vulnerable to damaging spring frost.

Persimmon performs well on deep, well-drained loam and sandy soils. As with most tree fruits, it needs protection from prolonged waterlogging, which restricts rooting and increases the risk of root problems.

Establishing a persimmon orchard begins with choosing a rootstock and cultivar suited to the site and market, including the choice between astringent and non-astringent types, since this decision shapes harvest timing and postharvest handling for the life of the planting.

• Rootstock selection for site adaptation and vigor
• Cultivar selection between astringent and non-astringent types according to market preference
• Tree spacing and canopy/pruning system suited to the growing region
• Long-term orchard floor and canopy management across many productive years

Potassium supports fruit size and quality, calcium is associated with fruit firmness as in many other tree fruits, and boron is a micronutrient commonly monitored for its role in flowering and fruit set.

Persimmon sheds fruit when it is stressed, and it sheds it late. The tree carries a heavy crop on brittle wood into autumn, well after most orchard fruit is off, so a dry spell in the last weeks before harvest arrives when the fruit is at its most valuable and the tree has least ability to compensate. Growers irrigate persimmon further into the season than they would a stone fruit for that reason.

Irrigation scheduling aims to avoid water stress during fruit growth while preventing waterlogging, which the tree tolerates poorly, particularly over prolonged periods.

Anthracnose can affect persimmon leaves, twigs, and fruit, while gray mold can affect flowers and fruit, particularly in cool, humid conditions or during storage. Overall, persimmon is considered relatively adaptable and pest-tolerant compared with many other tree fruits once established.

Scale insects, mealybugs, and thrips are common pests that can affect tree vigor and fruit finish.

Management combines orchard sanitation, monitoring, and — where justified — locally authorized control products applied according to their labels.

Harvest timing and handling depend heavily on the astringent/non-astringent distinction: non-astringent cultivars can be picked firm and eaten shortly after harvest, while astringent cultivars are generally either left to fully ripen and soften before eating or given a postharvest treatment to remove astringency prior to sale. Fruit is typically harvested by hand with the calyx (cap) attached.
