Creating a tepache garden in outdoor plant boxes is a fantastic way to grow the ingredients needed for this traditional fermented pineapple drink. The best plants for tepache gardens thrive in warm, sunny conditions and complement the fermentation process. Here are the top choices:

1. Pineapple (Ananas comosus): The star ingredient of tepache, pineapple plants love sunlight and well-drained soil. Their sweet, juicy fruit is essential for brewing.

2. Mint (Mentha spp.): Adds a refreshing twist to tepache. Mint grows vigorously in plant boxes and pairs perfectly with pineapple.

3. Ginger (Zingiber officinale): A natural fermenting aid, ginger enhances flavor and aids digestion. It grows well in containers with partial shade.

4. Cinnamon Basil (Ocimum basilicum 'Cinnamon'): This aromatic herb infuses tepache with warm, spicy notes and thrives in outdoor boxes.

5. Lemongrass (Cymbopogon citratus): Adds a citrusy zing and thrives in tropical climates. It’s easy to grow in plant boxes with ample sunlight.

For optimal results, ensure your outdoor plant boxes have good drainage and receive at least 6-8 hours of sunlight daily. Combine these plants to create a vibrant, productive tepache garden!
