Plant Sapphire Cascade Blueberry in well-draining, acidic soil with a pH of 4.5-5.5. Choose a sunny location with partial afternoon shade. Space plants 2-3 feet apart. Water regularly to keep the soil consistently moist but not waterlogged. Fertilize in early spring with a balanced, slow-release fertilizer formulated for acid-loving plants. Prune in late winter to remove dead or weak branches and encourage new growth. Protect from birds with netting if necessary.
