Yes, you can grow dwarf tea plants in an outdoor plant box! These compact varieties, such as Camellia sinensis, adapt well to container gardening when given the right conditions. Here’s how to ensure success:

1. Choose the Right Box: Opt for a sturdy, well-draining plant box at least 12-18 inches deep to accommodate root growth.

2. Soil Matters: Use acidic, loamy soil (pH 5.5-6.5) mixed with organic compost for nutrients.

3. Sunlight & Placement: Place the box in a spot with partial to full sunlight (4-6 hours daily) and shelter from strong winds.

4. Watering Routine: Keep the soil consistently moist but not waterlogged—dwarf tea plants thrive with regular, moderate watering.

5. Pruning & Care: Trim regularly to maintain shape and encourage bushier growth. Fertilize lightly during the growing season.

With proper care, your outdoor plant box can yield fresh tea leaves for years. Happy gardening!
