Start with a simple planting of Rockberry in your garden for a low-maintenance, edible shrub.
Rockberry plants or seeds, potting mix suitable for ericaceous plants, and containers if starting from seed.
Plant Rockberry in early spring or late fall when the soil is moist but not waterlogged.
Use a well-draining potting mix with added sand for good drainage. Ensure containers have adequate drainage holes.
Transplant young Rockberry plants directly into the garden bed, spacing them about 30 cm apart. For seeds, sow in containers and transfer to the garden after germination.
Keep the soil consistently moist during the first few weeks. Avoid overwatering as this can lead to root rot.
Water Rockberry when the top inch of soil feels dry, especially in dry spells. Provide light to partial shade and mulch around the base for moisture retention.
Prune Rockberry after fruiting to maintain shape and encourage new growth. Harvest ripe berries by gently pulling them off the plant.
Overwatering, planting in heavy soil without proper drainage, and not providing enough light are common pitfalls for beginners.
