Act 3 scene 4 Gardener Scene
The gardener comments on the political situation in England under Richard using the garden as a metaphor, with Richard as a poor gardener who did not prune when necessary, puncture the bark of the fruit trees when necessary, and allow fruitful boughs to live.
The Queen creates the idea of England being like the Garden of England (in the same belief structure as Gaunt professed in his royal throne of kings speech) and Richard is like Adam as well as the designated gardener of England. She questions who has tempted him like Eve did to predict the fall of Richard, and undoubtedly sees Bolingbroke as the serpent.
The gardener refers to a balance on which those who support Bolingbroke far outweigh those who support Richard, supporting the way more and more men seems to be with Bolingbroke and fewer with Richard. This scene may also be used by Shakespeare first to create a buffer between the Flint Castle scene and the Abdication scene and also to show Richard in a sympathetic light through his Queen. We saw her only once before and will see her again at the end, always in support of Richard.
