Pruning was the act of trimming plants to remove dead portions and encourage new growth. In 2268, Spock compared Harry Mudd and USS Enterprise landing party's confounding of the Mudd androids to pruning leaves and branches from a tree, saying it was time to work on the root (that is, Norman.) (TOS: "I, Mudd" ) In 2377, Jaryn reminisced about her family, picturing her father pruning his cona vines in his airponics bay. (VOY: "Body and Soul")
