Creating a mini smoothie garden in an outdoor plant box is a fun and rewarding way to grow fresh ingredients for your favorite blends. Start by selecting a sunny spot for your plant box, ensuring it gets at least 6 hours of sunlight daily. Choose compact, high-yield plants like strawberries, blueberries, spinach, kale, and mint, which thrive in small spaces. Use nutrient-rich soil and ensure proper drainage to keep your plants healthy. Water regularly and harvest leaves and fruits as needed for your smoothies. With minimal effort, you’ll enjoy fresh, homegrown smoothie ingredients all season long!
