Dedicated Budbreak Protection for Kiwifruit
Scientific Risk Management for Spring Climate Challenges — Securing the Foundation for a High-Yield Season
From late February to March, European kiwifruit-growing regions enter the most sensitive and decisive stage of the annual production cycle: budbreak.
During this period, vines emerge from dormancy, young shoots begin to grow, and flower differentiation enters a decisive stage. The level of protection during this window directly determines budbreak uniformity, flower quality, and final fruit set.
However, increasing climate volatility — including late frost, heavy rainfall and hail — poses significant risks to both open-field and greenhouse production systems.
Based on a detailed understanding of regional climate conditions and cultivation models across Europe, we have developed a “Bud Protection + Environmental Control” integrated solution, specifically designed for the February–March vulnerability period. The system balances physical protection with the biological needs of kiwifruit, helping growers secure the foundation for stable production throughout the year.
1. Open-Field Orchards in Spain & Italy
Combined Hail Netting + Rain Shelter System
Southern European Mediterranean regions are characterised by rapid spring warming, but also sharp temperature fluctuations and a high risk of hail and intense rainfall.
Growers in areas such as Italy’s Latina province have increasingly adopted protective membranes and wind systems in response to more frequent extreme events.
Core Components
High-Resilience Hail Netting
Manufactured from high light-transmission materials, these nets effectively absorb hail impact and protect young shoots from mechanical damage. Studies indicate that light-permeable hail nets provide strong protection with minimal impact on photosynthesis. Different net colours (blue, grey, red, white) can influence fruit size and quality, allowing optimisation according to cultivar characteristics.
Arched Rain Shelter Structure
Designed to integrate seamlessly with existing kiwifruit trellis systems, the arched structure ensures rapid rainwater runoff, reducing orchard humidity and limiting disease pressure caused by waterlogging.
In addition, research shows that the combination of netting and canopy cover can reduce nocturnal long-wave radiation loss, slowing canopy temperature decline — a valuable benefit during late spring frost events.
Integrated Benefits
- Stabilised temperature and humidity during budbreak
- Higher bud survival and improved floral quality
- Stronger foundation for uniform fruit set
Recommended for:
Open-field orchards in Southern Italy and Eastern Spain, particularly for climate-sensitive cultivars such as Hayward and yellow-fleshed varieties.
2. Germany & Netherlands
Lightweight Shade Net + Ventilated Rain Shelter System
In Central and Northern Europe, kiwifruit production typically combines greenhouse and open-field cultivation. This creates additional microclimate management challenges.
Inside greenhouses, early budbreak can be affected by overheating and excessive humidity. Outdoors, protection from rainfall, ventilation control and radiation management are equally important.
Core Components
Lightweight Shade Netting (Greenhouse Application)
Filters excessive solar radiation, preventing bud scorch and moderating internal temperatures. This supports uniform budbreak and avoids overly rapid temperature rises.
Ventilated Retractable Rain Shelter (Open-Field Application)
A retractable system offering three operational modes:
- Closed during rainfall: protects against excess moisture and reduces disease pressure
- Open during stable weather: ensures optimal ventilation and natural light exposure
- Partially shaded during peak radiation: reduces heat stress and sunburn risk
Greenhouse Synergy
The integrated approach reduces fungal disease risk caused by high humidity while ensuring strong, uniform early growth.
3. Universal Advantages Across European Regions
Regardless of location, the following system features provide additional long-term value:
Seamless Integration with Existing Trellis Systems
All protective structures are engineered to match existing kiwifruit support frameworks, avoiding major structural modifications and ensuring efficient installation.
Optimised Light Transmission
Materials are designed to maintain sufficient light during budbreak, supporting floral differentiation and early carbohydrate accumulation.
Aligned with Sustainable Agriculture Goals
By reducing rain exposure and disease incidence, protective systems lower reliance on chemical treatments. This supports European sustainability standards and strengthens competitiveness in premium and export markets.
Protect Budbreak — Protect the Season
Budbreak is the critical first step in the annual production cycle. Effective protection during this stage prevents later yield losses and quality decline.
