Garden enthusiasts are being advised to consider replacing hydrangeas with more drought-resistant alternatives as climate change takes its toll. Experts warn that hydrangeas, which require ample water, are struggling in increasingly dry conditions, even in traditionally suitable regions.
One nursery owner reported losing nearly 70% of their hydrangea collection during the 2022 heatwaves, despite daily watering. Symptoms of a dying hydrangea include burnt foliage, curling leaves, faded colour, and drooping stems.
Professional gardeners recommend alternatives such as lavender, ceanothus, and Russian sage, which offer vibrant blooms but require less water. Planting drought-resistant bulbs in cooler, wetter areas can also help create a resilient garden.
For those who wish to keep hydrangeas, gardening expert Alan Titchmarsh advises providing good, moist soil and a spot in sun or dappled shade. He notes that blue hydrangeas need acidic soil to stay blue.
