Persimmon Jiro

Diospyros kaki 'Jiro'

tree

Jiro is a non-astringent Japanese persimmon cultivar known for its large, flattened fruit and excellent flavor when firm. It's a deciduous tree that produces abundant crops and is one of the most reliable and popular persimmon varieties for home gardeners. The tree has attractive foliage and vibrant fall color before dropping its leaves.

Growing Conditions

☀️

Sun: Full sun, 6-8 hours daily; more sun ensures better fruit quality and flavor

💧

Water: Deep, regular watering during the first 2-3 years to establish roots. Once established, drought-tolerant but benefits from consistent moisture during fruit development. Water deeply during dry spells, especially when fruit is sizing.

📏

Spacing: 300 inches

📅

Days to maturity: 3-4 years from planting to first significant fruit; 5-6 years for full production

🌱

Planting depth: Plant at same depth as root ball; do not bury the trunk

Soil

Type: Well-draining loamy to sandy soil

pH: 6.0-7.5

Amendments:

Compost or aged manure at planting Mulch (2-3 inches) to retain moisture and regulate temperature Avoid heavy clay; amend with sand or perlite if needed

Growth Stages

Establishment (Years 1-2)

2 years

Young tree focuses on root development and structural growth. Leaves emerge in spring; tree gradually increases in size.

Water regularly (1-2 inches per week). Stake if needed. Prune only to remove damaged branches. Remove any early flower buds to encourage vegetative growth.

Juvenile Growth (Years 3-4)

2 years

Tree becomes more robust and woody. Begins setting flowers and small fruit. Foliage becomes fuller and more developed.

Continue deep watering. Begin light pruning to establish open branching structure. Thin excessive fruit to encourage larger specimens. Apply balanced fertilizer in spring.

Flowering

3-4 weeks

Small, creamy-white or pale yellow flowers appear in spring (May) along the branches. Flowers are inconspicuous but fragrant.

Persimmons are largely self-fertile (Jiro sets fruit parthenocarpically), so pollinator activity is secondary. Avoid heavy pruning during flowering.

Fruit Development & Sizing

16-20 weeks

Fruitlets develop over summer, gradually enlarging. Jiro fruits are large, flattened, and turn deep orange as they mature in fall (September-November).

Thin fruit to 1 every 6 inches for larger specimens. Water consistently during this stage. Monitor for pests. Stop nitrogen fertilization in mid-summer to avoid excessive vegetative growth.

Ripening & Harvest

4-6 weeks

Fruit reaches full size and develops rich orange color. Flesh becomes soft and translucent. Tree's foliage turns brilliant gold, red, and orange.

Harvest when fruit is fully colored and slightly soft to touch. Jiro is non-astringent and can be eaten firm or soft. Handle carefully to avoid bruising.

Companion Planting

Plan your garden →

Plant with:

Nitrogen-fixing legumes (clover, vetch) as groundcover Shallow-rooted herbs (thyme, oregano) Flowering shrubs for pollinator attraction Alliums to deter some pests

Avoid planting near:

Black walnut (produces juglone toxin) Other persimmon varieties for genetic diversity and pest management Plants requiring consistent high moisture (persimmons prefer drier soil)

Common Pests

Hand-pick early morning or use Japanese beetle traps. Neem oil or spinosad for heavy infestations. Avoid broad-spectrum insecticides that harm beneficials.
Remove affected leaves. Improve air circulation through pruning. Apply copper fungicide in spring as preventive. Avoid overhead watering.
Spray with strong water stream or insecticidal soap. Ensure adequate humidity. Neem oil for persistent infestations.
Horticultural oil spray in dormant season. Remove heavily infested branches. Encourage beneficial insects.
Install 8-foot fencing or use deer repellents. Young trees are more vulnerable; protect with physical barriers.

Harvest Tips

Jiro is a non-astringent variety and can be eaten when firm (like an apple) or when soft and translucent (traditional preference). Harvest when fully colored (deep orange) in October-November. Pick by gently twisting or using pruners to avoid tearing the branch. The fruit will continue to ripen slightly after harvest if stored at room temperature. Store in cool conditions (35-45°F) for extended shelf life.

Fun Facts

🌱 Jiro is one of the few persimmon varieties that produces seedless fruit parthenocarpically (without pollination), making it reliable for home growers.
🌱 The name 'Jiro' comes from Japan, where it has been cultivated for centuries; it's one of the oldest continuously grown persimmon cultivars.
🌱 Persimmon trees are extremely long-lived and can produce fruit for 50+ years with minimal care once established, making them a generational investment.
