Yuzu fruit: How to grow?
Growing yuzu fruit necessitates paying close attention to particular guidelines and circumstances. This is a basic guide to yuzu cultivation:
- Climate: Subtropical to temperate regions are ideal for yuzu tree growth. For best development, Yuzu prefers full sun exposure.
- Soil: Sandy or loamy soil that drains well and has a pH between that of a slight acid and that of neutral is preferred by yuzu trees. To avoid waterlogging, proper drainage is crucial.
- Planting: In the spring, plant young trees or yuzu seeds. Create a hole that is the same depth and twice as big as the root ball. Multiple trees should be spaced at least ten feet apart.
- Irrigation: Yuzu plants require frequent irrigation, particularly in the dry months. But be careful not to overwater them, as they are prone to root rot. Between waterings, let the soil dry out.
- Fertilisation: Apply a balanced citrus fertiliser to yuzu trees in the spring and summer. Avoid using too much nitrogen and abide by the dose recommendations on the fertiliser container.
- Pruning: Remove damaged or dead branches from yuzu trees and prune them to shape them. Enhancing air circulation inside the canopy is another benefit of pruning. Perform this in the early spring or late winter.
- Cold protection: Although young yuzu trees may require protection in colder locations, mature trees may tolerate some degree of cold. For the winter, consider covering the trunk with burlap or using frost blankets.
- Insect control: Look out for typical citrus pests such as scale insects, spider mites, and aphids. When using chemical or natural insecticides, be sure you adhere to the suggested usage directions.
- Harvesting: When yuzu fruits are mature, they are usually harvested in late fall or early winter. Even though the fruits still have a green appearance, as they develop, their flavor gets stronger.

Yuzu fruit: Care tips
- Climate and soil: Yuzu prefers warm weather, while it can withstand some degree of cold. Plant on sandy-loam soil that drains well and has a pH range of slightly acidic to neutral.
- Light: To guarantee ideal fruiting, expose plants to full light for a minimum of 6-8 hours each day.
- Watering: Apply water regularly to ensure that the soil is continually moist. Yuzu is susceptible to both flooding and drought.
- Fertilisation: Apply a balanced citrus fertiliser in the spring and late summer. Avoid fertilisers with a lot of nitrogen.
- Pruning: Prune to eliminate dead or congested branches and to form the tree. As a result, airflow and solar penetration are enhanced.
- Cold orotection: Keep young trees safe from frost. While mature trees can withstand low temperatures, prolonged exposure to below-freezing temperatures might harm the fruit.
- Mulching: To keep soil moist and discourage weed growth, spread a layer of mulch around the base.
- Harvesting: Yuzu should be harvested as soon as it turns yellow. As the fruit ages, its flavour becomes more intense.
- Disease and pest management: Look out for pests such as scale insects and aphids. For control, apply neem oil or insecticidal soap. Treat citrus infections as soon as you notice any symptoms.
- Gardening in containers: Yuzu can be cultivated in containers. Make sure the pot has drainage holes and use a potting mix that drains well.
- Support for branches: Yuzu trees may produce a lot of fruit, so you might want to think about giving branches some support to keep them from breaking.
