Planting Instructions:

1. Seed Preparation: Stratify by placing seeds in a moist paper towel, sealed in a plastic bag, and refrigerating for 3-4 weeks.
2. Sowing: After stratification, start seeds indoors 8-10 weeks before the last frost. Plant 1/4 inch deep in seed trays or pots with quality seed-starting mix.
3. Germination: Keep soil moist and at 70-75°F (21-24°C); seeds germinate in 3-4 weeks.
4. Transplanting: After frost, harden off seedlings and transplant them 3-4 feet apart in rows spaced 6-8 feet apart.

Care:

• Watering: Maintain even moisture, especially in the first year; established plants are drought-tolerant but fruit best with regular watering.
• Mulching: Add mulch around the base to retain moisture, prevent weeds, and regulate temperature.
• Pruning: Prune annually; remove fruiting canes after harvest and thin new canes to boost airflow and reduce disease.
