🌱 How to Care for Blueberry to Prevent Aphids?

💧 How to Water

Water every 2–4 days during the growing season, maintaining consistently moist soil. Blueberries have shallow roots and are sensitive to drought stress. Avoid waterlogging as it promotes root rot. During winter dormancy, reduce watering significantly.

☀️ Lighting

Blueberries require full sun—at least 6–8 hours of direct sunlight per day—for optimal fruit production. Partial shade is tolerated but significantly reduces flowering and fruiting. Place in the sunniest location available in your garden.

🪴 Ideal Soil

Plant in acidic soil with a pH of 4.0–5.5. Use a peat-based mix enriched with organic matter. Avoid alkaline or compacted soils. If native soil is not acidic enough, amend with elemental sulfur or use raised beds filled with a blueberry-specific mix.
