Public parks across the United Kingdom are scorched yellow and fields have lost their green sheen as the nation endures sweltering conditions, drawing comparisons to the severe heatwave of 1976. With hosepipe bans in effect, residents are once again facing the challenge of conserving water, but lessons from 50 years ago offer practical, low-tech approaches to garden care.
In 1976, gardener Don Hoyle, appearing on BBC One's 'Nationwide' program on August 4, shared his methods for maintaining his garden without using a hosepipe. Hoyle emphasized using available water, such as bathwater, and directing it to plants that most needed it. His advice included utilizing peat for potted plants, as its absorbent nature helps retain moisture for extended periods after watering. He also suggested that for potted plants, removing all flowers and moving the containers to the shadiest, coolest part of the garden could help them survive for one to two weeks while the owner was on holiday.
For flowers planted in the ground, like Camellias, Hoyle recommended applying a layer of mulch before leaving. He advised soaking the plant with a bucket of bathwater, cautioning against using water from washing dishes or washing machines due to potential chemical content. A layer of grass mowings could then be used to seal in the moisture.
Hoyle also demonstrated methods for plants to water themselves, a technique he described as utilizing capillary action. He prepared a seedbox lined with polythene and filled with moist sand. This setup, when filled with water, would slowly percolate into the sand over about two days. Houseplants placed on top of this moist sand could then sustain themselves for a couple of weeks or more.
For produce such as tomatoes, Hoyle acknowledged the need for neighborly assistance if owners were away. He suggested offering vegetables and fruits as an incentive for neighbors to tend to the plants. Additionally, he mentioned a tip for tomato plants: covering their roots with old, baggy trousers could help retain moisture if a friend could water them even once a day.
His philosophy also included a pragmatic approach to the drought: accepting that some plants might not survive. Hoyle advised against wasting water on plants that would only last a few more weeks anyway, suggesting a focus on more resilient flora.
These historical tips come as Britain faces its own extreme heat. Temperatures have been recorded reaching 36.7C, with forecasts suggesting highs of 38C. An amber 'extreme heat' warning has been extended, and a UK Health Security Agency amber heat health alert is in effect, warning of a potential rise in deaths. Transport services are experiencing reduced operations, with passengers urged to travel only if essential due to the soaring temperatures. Fire services have also recorded a high number of wildfires, matching last year's total.
