The Chelsea Flower Show, a pinnacle event in the horticultural calendar, is gearing up to showcase gardens that grapple with an increasingly arid future, reflecting the pressing challenges posed by climate change. As this year’s show approaches, the chilly light of a dry spring has prompted both amateur gardeners and experienced designers to rethink their strategies in preparation for what might be a drought-stricken summer. The Environment Agency has issued alerts about the possibility of drought conditions, the likes of which have not been encountered in nearly 60 years, forcing many households to brace for potential water use restrictions.
In response to this alarming trend, the Royal Horticultural Society (RHS) has reported a significant 20% increase in inquiries from concerned gardeners since early April compared to the same timeframe last year. Queries have primarily revolved around the challenges of underperforming spring-flowering plants like lilacs and wisteria, underscoring the broader disruptions that erratic weather patterns are causing in horticulture.
Amid these difficulties, several gardens featured at the show are purposefully designed to address the dual threats of drought and flooding, presenting a vision for resilient landscaping. The King's Trust garden exemplifies this focus, aiming to blend innovative design with the natural resilience of certain plant species. Using non-cement construction methods, the garden promotes permeable surfaces that can help mitigate flash flooding during intense rainfall. This approach is not merely an aesthetic choice; it reinforces the notion of adaptability, mirroring the resilience young people supported by Charles’s charity are encouraged to embody.
Another imaginative entry, the Killik & Co Save for a Rainy Day garden, transports visitors 25 years into the future, envisioning how southern English gardens might adapt to a landscape increasingly marked by flood and drought. Designer Baz Grainger observed how contemporary practices must evolve, leading to the creation of a “flood zone” and utilising water collection techniques to buffer against harsh weather extremes.
The ecological narrative is further enriched by the Garden of the Future, which takes inspiration from agricultural practices in the global south. This garden showcases drought-resistant crops such as sweet potatoes and millet, creatively adapting to the changing climate and illustrating how traditional farming can inform sustainable practices in the UK.
However, the dry conditions leading up to the show have not favoured all participants. For example, Zoe Claymore’s temperate rainforest garden, aimed at highlighting the rare habitats now dwindling in the UK, has faced particular challenges. This unique project, which represents the Wildlife Trusts’ commitment to the preservation of these ecosystems, depends heavily on moisture-loving plants like ferns and mosses that have struggled to thrive in the ongoing dry spell.
The shift towards sustainability is also evident with innovative initiatives like Project Giving Back (PGB), which sponsors landscape designs that can aid communities after the event. This project has encouraged a departure from traditional corporate sponsorship, positioning philanthropy at the forefront of garden design. Showcasing a range of climate-adaptive plants, gardens inspired by landscapes such as volcanic regions and sand dunes serve to educate visitors on environmental stewardship.
Yet, not all developments are met with universal acclaim. The RHS's decision to extend its peat-free commitment until 2028 has drawn criticism amid growing concerns over the degradation of peatlands, vital carbon sinks that are quickly being lost. The continued reliance on peat in professional gardening media raises questions about the commitment of industry players to sustainability, especially at a time when ecological responsibility is more crucial than ever.
In light of this, the RHS is actively advising amateur gardeners to cultivate practices such as using water-efficient gardening techniques, employing organic matter to enhance soil retention, and mowing lawns slightly higher to encourage deep-root growth—all pragmatic responses to the current climatic upheaval.
As the Chelsea Flower Show unfolds, it is clear that the gardens are not just a canvas of beauty but also a poignant reminder of the reality of climate change. Each garden tells a story of resilience and adaptation, offering a glimpse into how we might cultivate our landscapes, homes, and communities in the face of volatile weather patterns ahead.
