Yes, you can grow dwarf citrus trees in an outdoor plant box! These compact trees are perfect for small spaces and container gardening. To ensure success, choose a sturdy, well-draining plant box at least 18-24 inches in diameter. Use high-quality potting soil mixed with compost for nutrients. Place the box in a sunny spot where the tree gets 6-8 hours of sunlight daily.

Water regularly, keeping the soil moist but not soggy, and fertilize every 4-6 weeks during the growing season. Protect the tree from extreme cold by moving the box indoors or covering it during frost. With proper care, your dwarf citrus tree can thrive and even produce delicious fruit in an outdoor plant box!
