🌱 Tips for Success

• Use a trellis or vertical support to train canes upward.
• Provide good airflow and bright light to prevent mildew.
• Prune old or dead canes after fruiting to promote healthy new growth.
• Feed monthly with a balanced organic fertilizer for best yields.

💧 Watering Tip

Keep the soil evenly moist — avoid both dryness and overwatering, which can cause root rot.

🌼 Fun Fact

Blackberries aren’t true berries! They’re “aggregate fruits” made up of tiny drupelets clustered together.
