Creating a mini mocktail garden in an outdoor plant box is a fun and practical way to grow fresh ingredients for refreshing drinks. Start by selecting a sturdy, well-draining plant box and placing it in a sunny spot. Choose a variety of cocktail-friendly herbs like mint, basil, and rosemary, along with edible flowers such as lavender or hibiscus for added flair. Arrange the plants based on their sunlight and water needs, leaving space for growth. Regularly prune and harvest to keep plants healthy and encourage new growth. With a little care, your mini mocktail garden will provide fresh, flavorful garnishes and infusions for your homemade beverages all season long.
