🌱 Tips for Success

• Use an acidic soil mix to keep the pH between 4.5 and 5.5.
• Provide a cool winter rest period if growing indoors year-round.
• Use rainwater or distilled water — tap water often raises soil pH.
• Choose compact varieties like ‘Top Hat’ or ‘Sunshine Blue’ for pots.
• Fertilize lightly with an acid-loving plant fertilizer during active growth.

💧 Watering Tip

Blueberries love consistent moisture — water when the top inch of soil feels dry, but ensure your pot drains well to prevent root rot.
