Growing a small hamamelis (witch hazel) in an outdoor plant box is entirely possible with the right conditions. Hamamelis is a hardy shrub that adapts well to containers, provided the plant box is large enough to accommodate its root system. Choose a well-draining potting mix and ensure the container has adequate drainage holes to prevent waterlogging. Place the plant box in a spot with partial to full sunlight, as hamamelis thrives in bright light but can tolerate some shade.

Regular watering is essential, especially during dry spells, but avoid overwatering to prevent root rot. Fertilize lightly in early spring to encourage healthy growth and vibrant blooms. Pruning is rarely needed, but you can trim to maintain shape after flowering. With proper care, your hamamelis will flourish in an outdoor plant box, adding beauty and seasonal interest to your garden or patio.
