Yes, you can successfully grow a small currant bush in an outdoor plant box, provided you meet a few key conditions. Currants thrive in well-draining soil and require ample sunlight, so choose a spacious box with drainage holes and place it in a sunny spot. A container at least 18 inches deep and wide is ideal to accommodate the root system.

Currants prefer slightly acidic to neutral soil (pH 6.0–7.0), so use a high-quality potting mix enriched with compost. Regular watering is crucial, especially during dry spells, but avoid waterlogging. Prune annually to encourage growth and fruit production.

Container gardening offers flexibility—you can move the plant box to optimize sunlight or protect the bush from harsh weather. With proper care, your currant bush will yield delicious berries even in a confined space. Happy gardening!
