Yes, you can grow a small daphne in an outdoor plant box, but it requires careful attention to its specific needs. Daphne plants are known for their fragrant blooms and compact size, making them suitable for container gardening.

To ensure success, choose a well-draining plant box with adequate depth (at least 12 inches) to accommodate the roots. Use a slightly acidic, loamy soil mix enriched with organic matter. Place the box in a spot with partial shade, as daphne prefers filtered sunlight and protection from harsh afternoon rays.

Water regularly to keep the soil moist but not soggy, as daphne is sensitive to both drought and overwatering. Fertilize lightly in early spring with a balanced, slow-release formula. Avoid transplanting frequently, as daphne dislikes root disturbance.

With proper care, your small daphne will thrive in an outdoor plant box, adding beauty and fragrance to your garden space.
