🗓️ When to plant

Plant in early spring before bud break, or in autumn after leaves fall. In mild climates, either season works; in cold regions, plant in spring.

🌰 How to plant

1. Dig a hole twice as wide as the root ball and just as deep.
2. Mix peat moss into the backfill soil to lower pH and improve drainage.
3. Place the plant so the top of the root ball is level with the ground; avoid burying the stem.
4. Water thoroughly and add 5–10 cm (2–4 in) of mulch around the base.

💧 Care

• Prune lightly in late winter to remove dead wood and shape the plant; avoid heavy pruning in early years.
• Mulch with 5–10 cm (2–4 in) of pine needles or peat moss to maintain acidity and moisture.
• Feed in early spring with an acidifying fertilizer formulated for blueberries or acid-loving plants.
• Plant at least two different varieties to ensure cross-pollination and better fruit set.

🧺 Harvest

Pick berries when fully blue and slightly soft, usually mid- to late summer; they'll continue ripening for 1–2 weeks after turning color. Gently roll ripe berries into your palm or use two fingers to pluck them.

🐛 Common problems

Mummyberry fungus: Remove and destroy infected berries; improve air circulation by pruning and apply a fungicide in early spring if needed.

Bird predation: Drape netting over plants during ripening, or plant extra berries to share with wildlife.

Spider mites: Spray with water to dislodge them, or apply insecticidal soap in hot, dry weather.
