Yes, you can grow tea plants (Camellia sinensis) in an outdoor plant box, provided you meet their specific needs. Tea plants thrive in well-draining, slightly acidic soil with a pH of 6.0–6.5. Choose a spacious plant box (at least 12–18 inches deep) to accommodate their root system. Position the box in a spot with partial to full sunlight (4–6 hours daily) and protect it from harsh winds.

Regular watering is essential—keep the soil moist but not waterlogged. In colder climates, move the box indoors or insulate it during winter, as tea plants are sensitive to frost. Prune annually to encourage bushier growth and harvest young leaves for homemade tea. With proper care, your outdoor plant box can yield fresh, aromatic tea leaves for years.
