References to gardens in the text are often metaphors for England. In Act 2, Scene 1 Gaunt laments the way Richard has not cared for England, which he compares to the Garden of Eden. In Act 3, Scene 4 the gardener and his man discuss the executions of Richard's followers Bushy and Green, wondering why they should keep the estate's own garden in order, "When our sea-wallèd garden, the whole land, / Is full of weeds, her fairest flowers choked up, / Her fruit trees all unpruned, her hedges ruined, / Her knots disordered, and her wholesome herbs / Swarming with caterpillars?" Bolingbroke also refers to Richard's close followers as "caterpillars of the commonwealth" in Act 2, Scene 4, suggesting they are feeding on the garden of England and harming it in the process.
