American vs Asian persimmon
Two persimmon species are commonly grown in North American home orchards, and they are different enough in cold hardiness, fruit astringency type, and size to warrant separate consideration. American persimmon (*Diospyros virginiana*) is native to the eastern United States, extremely cold-hardy,.

Two persimmon species are commonly grown in North American home orchards, and they are different enough in cold hardiness, fruit astringency type, and size to warrant separate consideration. American persimmon (Diospyros virginiana) is native to the eastern United States, extremely cold-hardy, and largely problem-free. Asian persimmon (D. kaki) produces larger, showier fruit but is less cold-hardy and requires more attention to astringency type and removal.
I don't grow persimmons at my zone 7a Long Island plot. Both species would grow here, and American persimmon in particular is virtually maintenance-free. This guide is sourced from Missouri Botanical Garden and NC State Extension.
American vs Asian persimmon at a glance
Per NC State Extension:
| Characteristic | American (D. virginiana) | Asian (D. kaki) |
|---|---|---|
| Cold hardiness | Zones 4-9 | Zones 7-10 |
| Tree size | 15-30 feet; can reach 60 feet | 15-25 feet |
| Fruit size | Small (golf ball to plum-sized) | Large (apple-sized) |
| Fruit color | Orange-yellow when ripe | Orange to red |
| Astringency | Always astringent; needs full ripening | Astringent or non-astringent types |
| Self-fruitful | Sometimes; improved with pollinator | Mostly self-fruitful |
Astringency: the critical distinction
Per Missouri Botanical Garden, persimmon astringency is caused by soluble tannins. When levels are high, eating the fruit causes an overwhelming puckering sensation that makes the fruit inedible. Tannins become insoluble as the fruit ripens, removing astringency.
Astringent types (American persimmon and astringent Asian types): Must be fully ripe (very soft, almost translucent) to be edible. American persimmons are edible only after a frost or when they are extremely ripe. Premature eating of astringent persimmon is unpleasant.
Non-astringent types (certain Asian cultivars only): Per NC State Extension, non-astringent Asian persimmon cultivars like 'Fuyu' and 'Jiro' can be eaten while still firm, crisp, and apple-like. They do not need to be fully soft.
Non-astringent cultivars include: 'Fuyu', 'Jiro', 'Izu'. Astringent cultivars include: 'Hachiya', 'Tamopan', 'Saijo'. 'Hachiya' is the large, acorn-shaped type commonly found in stores.
USDA hardiness zones
Per Missouri Botanical Garden:
- **American persimmon (D. virginiana):** Zones 4-9
- **Asian persimmon (D. kaki):** Zones 7-10
In zone 6, Asian persimmon can be grown in sheltered microclimates but is not reliably hardy. American persimmon is the practical choice for zones 4-6.
Light requirements
Per NC State Extension, both species require full sun — 8 hours minimum — for maximum fruit production. American persimmon tolerates partial shade (native to forest edges) but fruits more heavily in full sun.
Planting
Per NC State Extension, persimmons have a deep taproot and do not transplant well from bare root. Purchase container-grown trees and plant in spring with minimal root disturbance.
- Spacing: American persimmon 20-25 feet; Asian persimmon 15-20 feet
- Soil: Well-drained; pH 6.0-6.5
- Both species tolerate a wide range of soil conditions once established
American persimmon is notably tolerant of poor, dry soils once established — it is native to a wide range of forest, edge, and disturbed-ground habitats.
Watering
Per Missouri Botanical Garden, established persimmon trees are drought tolerant. Water young trees at 1 inch per week for the first 2 growing seasons. After establishment, supplemental irrigation is needed only during extended droughts.
Fertilizing
Per NC State Extension, persimmons are light feeders. Apply a balanced fertilizer (10-10-10) at 1/4-1/2 pound per year of tree age in early spring. In very fertile soil, no fertilization may be needed. Over-fertilization reduces fruit set and increases vegetative growth.
Pollination
Per Missouri Botanical Garden, American persimmon is dioecious — plants are either male or female. Most named cultivars (which are female) produce fruit without a pollinator, but fruit set and size is often better with a male pollinator nearby. Wild male trees in the neighborhood may serve as pollinators.
Asian persimmon is generally self-fruitful.
Pruning
Per NC State Extension, persimmons require minimal pruning compared to apples or peaches. Annual goals:
- Remove dead, damaged, crossing branches
- Maintain manageable tree height for harvest
- Open the canopy to light
Prune in late winter (February-March) before bud swell. Persimmons bleed sap from cuts; this is normal and not harmful. Avoid heavy pruning that reduces fruiting wood.
Harvesting
Per NC State Extension:
American persimmon: Harvest when fully soft and orange-amber, after frost in zones 5-7. Do not pick until the fruit is almost falling from the tree. Unripe American persimmon is inedible.
Asian persimmon (non-astringent types): Harvest when orange and full-sized but still firm. Eat immediately or store at room temperature for a few days.
Asian persimmon (astringent types): Allow to ripen fully on the tree or pick when full-sized and ripen at room temperature until very soft. Alternatively, subject to freezing temperatures to accelerate tannin breakdown, a traditional technique per Missouri Botanical Garden.
Pests and diseases
Per NC State Extension, persimmons have relatively few serious pest problems:
Persimmon psyllid: Causes leaf distortion; rarely serious.
Anthracnose: Spotting on fruit in wet conditions. Rarely severe enough to require treatment.
Borer insects: Occasional. Maintain vigorous tree health.
American persimmon, in particular, is notably resistant to most pests and diseases — one of its primary advantages over all other fruit trees in this guide.
Common problems
| Symptom | Likely cause | Fix |
|---|---|---|
| Fruit is inedible, puckering | Astringent type harvested unripe | Allow to fully soften; frost helps; wrong time |
| Heavy fruit drop | Normal June drop; drought | Normal if some fruit remains; irrigate in drought |
| No fruit | All-male tree; pollination failure | Plant named female cultivar; check for male pollinator |
| Bark cracking on young trees | Sunscald in winter | Wrap trunk with tree wrap first winter |
| Poor fruit size | Tree needs maturing; drought | Normal for first 5 years; irrigate in dry periods |
Frequently asked questions
Why does American persimmon have to wait for frost? Per Missouri Botanical Garden, frost does not actually change the chemistry of American persimmon — full ripeness and very low temperatures both cause soluble tannins to become insoluble, removing astringency. The frost rule is traditional and generally reliable, but a fully ripe American persimmon that has never frosted is also edible. The problem is that by the time American persimmon is soft enough to eat, frost has usually occurred in most of its range.
Is Fuyu persimmon non-astringent even when unripe? Per NC State Extension, 'Fuyu' is a non-astringent type that can be eaten firm and crisp, similar to an apple. However, very green, immature 'Fuyu' fruit harvested well before full color change may still have elevated tannin levels. For best flavor, harvest 'Fuyu' when fully orange.
How long before a persimmon tree produces fruit? Per Missouri Botanical Garden, Asian persimmon container-grown transplants typically produce first fruit in year 3-5. American persimmon may take 6-8 years from a seedling; named cultivars on rootstocks are faster.
Can I eat persimmon leaves or use them in cooking? Per NC State Extension, persimmon leaves (particularly American persimmon) are used in herbal teas in some traditional practices. The leaves are not toxic, but they are not documented as a primary culinary ingredient in Extension literature. Focus culinary use on the fruit.
