Creating a mini boricha garden in an outdoor plant box is a delightful way to enjoy these versatile plants even in limited spaces. Start by selecting a sturdy, well-draining plant box that fits your outdoor area. Fill it with a mix of nutrient-rich soil and compost to ensure healthy growth. Plant boricha seedlings or cuttings, spacing them evenly to allow room for expansion. Water regularly, keeping the soil moist but not soggy, and place the box in a spot with partial sunlight for optimal growth. With minimal care, your mini boricha garden will thrive, adding greenery and charm to your outdoor space.
