Create a serene and peaceful kitchen by incorporating a built-in indoor fruit and citrus tree grove inspired by Zen gardens. Choose citrus varieties like yuzu, mandarin, and pomelo to enhance the Zen atmosphere. Use natural materials like bamboo, stone, and wood for your kitchen design. Add a small water feature or a mini rock garden to create a sense of tranquility. The combination of fresh citrus scents and Zen elements will make your kitchen a calming retreat.
