Mottisfont’s roses bloom weeks early in climate-driven spectacle

MOTTISFONT, Hampshire — The rose garden at Mottisfont, one of Britain’s most celebrated National Trust sites, is erupting in color weeks earlier than usual, a phenomenon its head gardener calls "unprecedented in living memory." Rob Ballard, Mottisfont’s senior gardener, said the roses began blooming in early May, typically reserved for June, after a winter of relentless rain followed by a rapid warm spell in April. "The combination of 42 consecutive days of rain at the start of the year and then a sudden spike in temperatures jumpstarted the entire growth cycle," Ballard said. "We’ve never seen anything like it."

The early bloom is not an isolated incident. National Trust gardens across southern England—including Buckland Abbey in Devon and Chartwell in Kent—are reporting similar shifts, while northern sites remain on schedule due to lingering chill. At Buckland Abbey, senior gardener Sam Brown noted roses there are flowering two to three weeks ahead of their usual rhythm. "Shorter dormancy periods mean pests are surviving winter in greater numbers, and summer droughts are becoming the norm," Brown said. "We’re having to rethink everything from pruning schedules to soil management."

Ballard’s team has spent months preparing for the anomaly. They’ve mulched the entire garden to lock in moisture, suppress weeds, and bolster soil health—a critical step for both the roses and the earthworms beneath them. "Mulching isn’t just about keeping plants hydrated; it’s about building resilience," he said. "Every layer of organic matter we add acts as a buffer against extreme weather."

Mottisfont’s collection includes over 1,000 rose plants spanning nearly 500 varieties, many of which are rare or historically significant. Among them, the ‘Adélaïde d'Orléans’—a delicate 19th-century Bourbon rose—is being allowed to grow in a more natural, less rigid manner to reduce shock. "We’re trying to let these roses behave like they would in the wild," Ballard said. "It’s a shift away from the formal garden aesthetic, but survival comes first."

National Trust horticultural specialist Rebecca Bevan confirmed the trend is part of a broader shift across the organization’s 300 gardens. "We’re seeing climate change reshape our entire approach," she said. "From selecting drought-resistant species to redesigning planting layouts, we’re moving toward long-term sustainability rather than short-term spectacle." Bevan added that visitors should expect shorter but more intense flowering seasons, with some gardens now offering extended opening hours to accommodate the early rush.

For those planning to visit, Ballard recommends checking the National Trust’s website for updated bloom times and special early openings. "This year’s display is spectacular, but it’s a sign of bigger changes ahead," he said. "We’re witnessing nature’s way of telling us that the old rules no longer apply."
