'Gardening' was the British overall designation for aerial minelaying to hinder the movement of German naval and mercantile shipping in European waters (spring 1944/May 1945).
Such minelaying was usually undertaken by night bombers, and the first such operation, along the Danube river in Hungary and Romania, was undertaken on 8 April 1944 by Air Vice Marshal J. H. I. Simpson’s No. 205 Group of Major General Nathan F. Twining’s Mediterranean Allied Strategic Air Force within Air Chief Marshal Sir Arthur Tedder’s Mediterranean Allied Air Forces.
