Creating a mini posca garden in an outdoor plant box is a fun and creative way to bring greenery into small spaces. Start by selecting a sturdy plant box with good drainage. Fill it with a mix of potting soil and compost to provide nutrients. Choose a variety of small, hardy plants like succulents, herbs, or flowering annuals for a vibrant look. Arrange them in clusters for visual appeal, leaving space for growth. Water lightly and place the box in a spot with partial sunlight. Regular maintenance, like pruning and fertilizing, will keep your mini garden thriving. This project is perfect for balconies, patios, or even as a decorative piece in your yard. Enjoy your tiny oasis!
