Yes, you can grow a small gooseberry bush in an outdoor plant box! Gooseberries are hardy plants that adapt well to container gardening, making them ideal for small spaces like balconies or patios. To ensure success, choose a compact variety suited for containers, such as 'Hinnomaki Red' or 'Pixwell.'

Use a large, sturdy plant box (at least 18 inches deep and wide) with good drainage. Fill it with well-draining, nutrient-rich soil mixed with compost. Gooseberries thrive in full sun to partial shade, so place the box in a spot with at least 6 hours of sunlight daily.

Water regularly to keep the soil moist but not waterlogged, and fertilize lightly in early spring. Prune annually to maintain shape and encourage fruiting. With proper care, your gooseberry bush will produce delicious, tangy berries in just a few years!
