began to affect food supplies. The situation began to ease in 1943; however, home gardens continued throughout the war. Britain In Britain, "digging for victory" used much land such as waste ground, railway edges, ornamental gardens and lawns, while sports fields and golf courses were requisitioned for farming or vegetable growing. Sometimes a sports field was left as it was but used for sheep-grazing instead of being mown (for example see ). Other schools, like Winchester College, ploughed their fields to grow vegetables for school consumption, supplementing the meagre soil fertility by raising pigs for their manure. By 1943, the number of allotments had roughly doubled to 1,400,000, including rural, urban and suburban plots. C. H. Middleton's radio programme In Your Garden reached millions of listeners keen for advice on growing potatoes, leeks and the like, and helped ensure a communal sense of contributing to the war effort (as well as a practical response to food rationing). County Herb Committees were established to collect medicinal herbs when German blockades created shortages, for instance in Digitalis purpurea (Foxglove) which was used to regulate heartbeat. Victory gardens were planted in backyards and on apartment-building rooftops, with the occasional vacant lot "commandeered for the war effort!" and put to use as a cornfield or a squash patch. During World War II, sections of lawn were publicly plowed for plots in Hyde Park, London to promote the movement, while allotments growing onions in the shadow of the Albert Memorial also pointed to everybody, high and low, chipping in to the national struggle. Both Buckingham Palace and Windsor Castle had vegetable gardens planted at the instigation of King George VI to assist with food production. United States Amid regular rationing of food in Britain, the United States Department of Agriculture encouraged the planting of victory gardens during the course of World War II. Around one third of the vegetables produced by the United States came from victory gardens. It was emphasized to American homefront urbanites and suburbanites that the produce from their gardens would help to lower the price of vegetables needed by the US War Department to feed the troops, thus saving money that could be spent elsewhere on the military: "Our food is fighting", one US poster read. By May 1943, there were 18 million victory gardens in the United States – 12 million in cities and 6 million on farms. Eleanor Roosevelt
