Key Takeaways:
- Bloom Fresh developed low chill cherry varieties to address challenges posed by climate change.
- These varieties require fewer chilling hours, enabling cherry cultivation in warmer regions.
- Low chill cherries extend the growing season and increase yields for growers.
- They contribute to more sustainable production by reducing transportation distances and boosting local economies.
The Changing Landscape of Cherry Farming
Cherry farming has traditionally been limited to cool climates with long winters due to the need for chilling hours. With rising global temperatures and milder winters, many cherry growers face difficulties meeting these chilling requirements. Bloom Fresh has developed low chill cherry varieties to address these challenges. According to Josep Estiarte, CEO of Bloom Fresh, “Our low chill cherry varieties were developed in response to the growing concern about climate change and its impact on traditional cherry-growing regions. We saw a need to adapt and innovate to ensure cherries remain accessible, regardless of temperature shifts.”
Climate Change Challenges: Addressing Chilling Hour Requirements
Traditional cherry trees require between 800 and 1,000 chilling hours, where temperatures fall below 45°F (7.2°C), to break dormancy and produce fruit. As global temperatures rise, fewer regions can provide these chill hours, threatening cherry production. Estiarte explained, “Most traditional cherries need a minimum of 800 chill hours, but our low chill varieties can produce fruit with less than half of that. This opens up opportunities for cultivation in areas with warmer winters.”
Growing Conditions: Low Chill vs. Conventional Varieties
The key difference between low chill and conventional cherry varieties is the number of chilling hours required. This adaptation allows cherry cultivation in regions where traditional varieties would struggle. Estiarte stated, “Our low chill varieties can thrive in climates where traditional cherries cannot. This expands the growing areas and reduces the need for specialized care and chemical inputs.”
Extended Growing Seasons and Increased Yields
One major advantage of low chill varieties is their ability to extend the growing season. “These varieties don’t rely on long winters, allowing for earlier harvests in warmer climates, effectively extending the cherry season,” said Estiarte. He added, “We’ve seen yield increases of 20-30% compared to traditional varieties. By spreading out the harvest period and reducing the risk of crop loss due to unpredictable weather, growers can plan more effectively and capitalize on a longer market window.”
Sustainability: A Reduced Carbon Footprint
Low chill varieties also support sustainability by enabling cherry cultivation closer to consumer markets. Estiarte explained, “As these cherries can be grown in warmer regions closer to large consumer bases, the need for transporting cherries across long distances is significantly reduced. This contributes to a more sustainable production system and supports local economies.”
Grower Feedback: Consistency and Quality
Grower feedback on low chill varieties has been positive, with many reporting consistent production. “These varieties are highly consistent in terms of yield, offering growers a reliable harvest year after year,” noted Estiarte. Regarding quality, he added, “Our low chill cherries have been well-received for their flavor, sweetness, and firmness. Taste tests show that they hold up just as well, if not better, than conventional varieties.”
Future Outlook: The Role of Low Chill Varieties in Cherry Farming
As climate change continues to affect agriculture, low chill varieties are expected to play a crucial role in the future of cherry farming. Estiarte emphasized, “These varieties are not just a temporary solution; they represent a long-term strategy for adapting to a changing climate. We expect them to become a critical part of cherry farming in warmer regions.” Bloom Fresh plans to continue innovating and expanding cherry production, focusing on sustainability and market demand.
