New Digital Tool Predicts Plant Survival in Changing UK Climate
The Garden Climate Assessment Tool helps gardeners transition from water-intensive classics to resilient species.
1Predicting Future Garden Viability
The Future National Gardens Group is developing the Garden Climate Assessment Tool to help UK gardeners adapt to shifting weather patterns. By inputting specific plant lists, users can evaluate how species will tolerate projected local climate conditions, including temperature fluctuations, dryness, and winter cold, moving beyond traditional 20th-century horticultural assumptions.
2Coalition of Horticultural Experts
This initiative involves a major coalition including the Royal Horticultural Society, the National Trust, and English Heritage. By pooling expertise and data from 289 UK gardens, the group aims to provide a robust, free risk-assessment platform. Professional gardeners began trialing the software this Monday to refine its predictive accuracy.
3Expanding on Global Models
The tool builds upon the Botanic Gardens Conservation International framework launched in Australia in 2022, which originally focused exclusively on trees. The UK coalition has significantly expanded this scope to cover a vast range of plants, currently incorporating data for up to 80,650 plant types to strengthen future climate predictions.
4Shifting Away from Classics
Climate change is forcing a departure from water-thirsty English garden staples like hydrangeas, delphiniums, and lush lawns. Experts emphasize that gardeners must now anticipate climate impacts rather than reacting to them. The tool provides the necessary data to identify struggling plants, allowing for a gradual transition toward more sustainable, climate-resilient collections.
5Designers Facing New Realities
Designers like Laura Carey are increasingly wary of planting species like silver birch in environments that lack consistent moisture. Recent hot summers have highlighted the vulnerability of traditional choices. The tool aims to support professionals in making long-term decisions by measuring plant performance against both increased temperatures and overall weather changeability.
6Addressing Regional Dryness
In regions like the east of England, which is the driest part of the country, the tool serves as a critical resource for those needing to abandon high-water-demand aesthetics. It provides the evidence-based support required to help gardeners overcome the cultural attachment to traditional English garden styles that are no longer viable.
7Limitations and Future Needs
While the tool offers significant predictive power, it currently lacks soil-type variables, a point raised by Kim Shrosbree of the Epsom Garden Society. Gardeners on chalk or clay soils face distinct challenges that are not yet captured, highlighting the need for future updates to include site-specific soil data for better accuracy.
8Moving Toward Tailored Advice
The shift toward climate-resilient gardening marks a move away from generic advice toward highly localized, individual plant assessments. As the tool evolves, it will become essential for gardeners to consider their specific micro-climates and soil conditions, ensuring that future planting choices remain sustainable despite the ongoing challenges of the climate crisis.
