Kiwi Bud Break - Guide to Successful Kiwi Bud Break

Bud break is a crucial stage in the kiwifruit growth cycle. As a kiwi grower, careful management of this period determines not only the quality of vegetative growth, but also production potential. It is also a phase when plants are most vulnerable to frost, fungal diseases, and nutritional deficiencies.

In this article, we offer you a practical and technical guide to successful bud break, accompanied by professional solutions from Kiwiverse, expert in kiwi cultivation.

What is bud break and why is it so important?

Bud break corresponds to the opening of buds and the beginning of young shoot growth. This phase marks the awakening of the plant after winter dormancy and prepares for the growing and fruiting season.

The key issues of bud break:

• Optimal vegetative growth: The young shoots formed during this period will determine the structure of the plant for the coming season.
• Preparation for flowering: Successful bud burst directly influences the size and quality of the fruit.
• Increased sensitivity: Shoots are particularly fragile when faced with fungal attacks, nutritional deficiencies and frost.

In summary, well-managed bud break is essential to maximize yield and ensure a high-quality harvest.

Critical factors to monitor during bud break

1. Fertilization: Prepare your plants for vigorous growth

The nutritional needs of kiwifruit increase significantly at bud break. Proper fertilization is essential to promote healthy growth.

• Nitrogen (N): Key element for shoot development.
• Recommended contributions: A basic dressing (compost) in the fall, followed by two split applications of nitrogen fertilizer:
• Just before bud break.
• Before flowering.
• Calcium (Ca): Strengthens cell walls, making young shoots more resistant to disease.
• Potassium (K): Promotes fruit formation and quality.

2. Protection against late frost

Young shoots are extremely sensitive to frost, especially in areas where night temperatures remain low in spring.

Preventive measures:

• Frost protection fabrics: Install protection over your plants in case of late frosts.
• Sprinkler irrigation: Create a protective layer of ice to prevent damage.
• Heating candles: Used in orchards to slightly increase the temperature and protect the buds.

3. Monitoring of cryptogamic diseases

Bud break is a time when plants are particularly vulnerable to fungal infections, such as bacterial canker and botrytis.

Preventive solutions:

• Apply copper-based treatments (such as Bordeaux mixture) immediately after pruning.
• Use biological products, such as Bacillus subtilis, to block the spread of fungi.
• Prune infected branches and burn waste to prevent contamination.

Cultural practices for successful bud break

1. A suitable size to promote ventilation

Prune your plants before bud break to ensure good air circulation between the branches. Optimal ventilation reduces humidity and limits the risk of fungal growth.

2. Soil management and drainage

• Well-drained soil prevents stagnant moisture, which is a trigger for fungal diseases.
• Avoid planting in low-lying or flood-prone areas.
• Add compost or other organic matter to improve soil structure.

3. Protection against climatic hazards

Plant windbreak hedges around your plot to reduce the impact of cold winds on your plants. These hedges also serve as a habitat for pollinating insects.
