Rain gardens and bathwater reuse becoming trends, RHS says

Chelsea flower show to focus on water reuse as gardeners prepare for shortages caused by climate crisis

Rain gardens and bathwater are becoming gardening trends, the Royal Horticultural Society has said, as gardeners battle predicted water shortages caused by climate breakdown.

At the Chelsea flower show this year, many of the gardens will be focused on reducing water usage. Rain gardens will be on show, including in the Water Aid garden, which includes a rainwater harvesting pavilion designed to slow its flow, collecting and storing it for irrigation of the garden and filtering it for use as drinking water.
