Characteristics

The shape of the fruit varies by cultivar from spherical to acorn to flattened or squarish. The color of the fruit varies from light yellow-orange to dark orange-red. The size can be as little as a few ounces to more than a pound. The entire fruit is edible except for the seed and calyx. Alternate bearing is common. This can be partially overcome by thinning the fruit or moderately pruning after a light-crop year.

Distribution

Climate and weather

Persimmons do best in areas that have moderate winters and relatively mild summers–suitable for growing in USDA Hardiness Zones 7 to 10. It can tolerate temperatures of 0° F when fully dormant. However, because of its low chilling requirement (less than 100 hours), it may break dormancy during early warm spells only to be damaged by spring frosts later. The leaves are killed by 26° F when growing. Trees do not produce well in the high summer heat of desert regions, which may also sunburn the bark.

Duration

Insect pests

Persimmons are relatively problem-free, although mealybug and scale in association with ants can sometimes cause problems. Ant control will usually take care of these pests. Other occasional pests include white flies, thrips which can cause skin blemishes and a mite that is blamed for the "brown lace collar" near the calyx. Waterlogging can also cause root rot. Vertebrate pests such as squirrels, deer, coyotes, rats, opossums and birds are fond of the fruit and gophers will attack the roots.

Diseases

Harvesting

Harvest astringent varieties when they are hard but fully colored. They will soften on the tree and improve in quality, but you will probably lose many fruit to the birds. Astringent persimmons will ripen off the tree if stored at room temperature. Nonastringent persimmons are ready to harvest when they are fully colored, but for best flavor, allow them to soften slightly after harvest. Both kinds of persimmons should be cut from the tree with hand-held pruning shears, leaving the calyx intact Unless the fruit is to be used for drying whole, the stems should be cut as close to the fruit as possible. Even though the fruit is relatively hard when harvested, it will bruise easily, so handle with care.
