Creating a mini daechu garden in an outdoor plant box is a delightful way to bring nature into small spaces. Start by selecting a sturdy plant box with proper drainage holes to prevent waterlogging. Fill the box with well-draining soil mixed with compost for nutrients. Choose compact daechu (jujube) varieties suitable for containers, ensuring they receive at least 6 hours of sunlight daily. Plant the daechu saplings, spacing them evenly, and water thoroughly. Add decorative elements like small rocks or miniature figurines for a whimsical touch. Regularly prune and fertilize to maintain healthy growth. This DIY project is perfect for balconies, patios, or tiny yards, offering both beauty and fresh fruit in limited space.
