FAQ
Do I need two Nashi trees?
Yes, Nashis are mostly self-sterile. A second variety or a suitable pear tree massively increases yield.

Book content
Main description
The Nashi combines pear aroma with apple-like crispness. It is a robust, high-yielding fruit tree that impresses with its juicy fruits and magnificent white blossoms in spring.
History
Originating in East Asia, it has been cultivated there for millennia and is now a symbol of the beginning of spring.

Thin out the canopy to promote light and air circulation.
Cultivation specs
Seed
Spacing
Spacing notes
Spacing depends heavily on the rootstock used (dwarf vs. vigorous).
Growth dimensions
Final size notes
Nashi trees often remain smaller than classic European pear trees.
Temperature
Temperature notes
The tree is hardy down to approx. -20°C, but the early blossom is susceptible to late frosts.
Water
Critical water phases
- Flowering
- Fruit set
- Fruit sizing
Water notes
Consistent moisture prevents fruit cracking.
Nutrition
Nutrition notes
Potassium-rich fertilization in summer promotes fruit ripening and frost hardiness.
Container
Container notes
Only suitable for containers when grown on dwarfing rootstocks.
Support
Support types
- stake
- espalier
Support notes
Staking in the first years or training as an espalier is recommended.
Cultivation modes
Yield density
Yield notes
Very high-yielding; regular thinning is mandatory for good fruit quality.
Site
Exposure
Sunny to partial shade, sheltered
Microclimate requirements
Warm location promotes sugar formation in the fruits.
Soil
Soil type
Loamy-humus, deep
Soil notes
Avoid highly calcareous soils (risk of chlorosis).
Watering
Strategy
Water regularly, especially during fruit development.
Nutrition
Deficiency symptoms
Yellow leaves due to iron deficiency on calcareous soil.
Cultivation planning
Succession sowing
Bed planning notes
Plan for a pollinator variety (another Nashi or certain pear varieties like 'Bartlett').
Crop rotation
Notes
As a long-lived woody plant, Nashi occupies its spot for decades. Watch out for soil fatigue when replanting on old pear sites.
Deficiencies
Common
- Slugiron-chlorosis
Name
Iron chlorosis
Symptoms
Yellow leaves with green veins, especially on calcareous soils.
Problems
Environmental
- Slugfruit-cracking
Name
Fruit cracking
Cause
Highly fluctuating water supply.
- Sluglate-frost-damage
Name
Late frost damage
Cause
Early blossom destroyed by frost in April or May.
Problem management
Common pest groups
- Aphids
- Moths
- Gall mites
Common disease groups
- Rust fungi
- Bacterial infections
- Scab
Prevention principles
- Site selection: Sunny and airy to dry leaves quickly.
- Pruning: Promote an open canopy.
- Choose resistant varieties.
Diagnosis notes
Pay close attention to leaf undersides and shoot tips in spring.

Toxicity notes
The fruit is non-toxic; seeds should not be consumed in large quantities.
Raw consumption
Excellent; Nashis are mostly eaten raw and peeled.
Seed saving
Method
Seed extraction from fully ripe fruit, cold stratification required.
Seed saving advanced
Genetic fidelity
Low (seedlings vary significantly from the parent variety).
Professional propagation
Grafting onto rootstocks such as Pyrus communis or Pyrus kappleana.
