Sécurité

Humains

Enfants
The fruit is safe for children, but ensure they do not eat unripe fruit to avoid digestive discomfort.
Allergènes de contact

La cultiver

Multiplication
grafting, seed, cuttings
Quand planter
spring, autumn
Hivernage
Apply a thick layer of mulch around the base to protect roots from deep freezes. Young trees may benefit from wrapping the trunk in burlap if extreme cold is expected.
En pot
Dwarf varieties can grow in large containers of at least 40 liters, but they prefer the ground.

Grafting

  1. 1. Select a healthy rootstock in late winter.
  2. 2. Use a scion from a known productive variety.
  3. 3. Perform a whip and tongue graft.
  4. 4. Secure the union with grafting tape.
  5. 5. Keep the graft union protected until growth begins.

Planting nitrogen fixing ground covers like clover beneath the canopy helps support the tree's growth.

Bonnes associations

  • Comfrey — It acts as a dynamic accumulator to bring nutrients to the soil surface.
  • Jonquille — These bulbs help suppress weeds around the base of the tree.

Espèces similaires

  • Diospyros virginiana — It is a hardier relative native to North America with smaller fruit.

Ce qu'on demande souvent

Why is my fruit puckering my mouth?
You are likely eating an astringent variety before it is fully soft and ripe.
Do I need two trees for fruit?
Most modern cultivars are self-fertile and will produce fruit without a partner.

D'où vient le nom

The genus name Diospyros comes from Greek meaning divine fruit, while kaki is the Japanese name for the tree.

Bon à savoir

  • Persimmons are technically berries.
  • The name Diospyros translates to fruit of the gods.
  • The fruit is a staple in many Asian cuisines during the winter months.
  • Some varieties must be bletted or ripened off the tree to lose their astringency.
