How Britons kept their lawns green during the 1976 heatwave: From covering plants in old clothes to using bathwater and sand… so how many are you still doing today?
The article revisits gardening advice broadcast during the 1976 heatwave, when water restrictions and prolonged hot weather left lawns, parks and gardens badly scorched. It matters because similar dry conditions and hosepipe bans are again prompting householders to look for ways to protect plants while conserving water.
BBC gardener Don Hoyle advised prioritising water for plants that needed it most, including reusing bathwater but avoiding water containing washing-up liquid or laundry chemicals. His suggestions included using peat in pots to retain moisture, cutting flowers from hanging baskets and moving them into shade before holidays, mulching plants such as camellias, and relying on neighbours to help with watering.
