Harvest Tips
Begin harvesting 8-10 weeks after planting. Pick berries when fully red and slightly soft—they do not ripen further after picking. Harvest every 2-3 days at peak season to encourage continued flowering. Handle gently as berries are delicate. Best flavor develops when picked in cool morning hours. Pinch off runners immediately to redirect energy to fruit production.
Fun Facts
- 🌱 Alpine Strawberry Rügen Improved is a day-neutral variety, meaning it produces flowers and fruit regardless of day length, unlike June-bearing strawberries that require specific photoperiods. This allows for continuous harvest from summer through fall.
- 🌱 The 'Rügen' designation comes from the German island of Rügen, where this improved cultivar was developed. The original alpine strawberry (Fragaria vesca) has been cultivated in European gardens for centuries and is smaller and less productive than this modern variety.
- 🌱 Alpine strawberries lack runners entirely, making them the only true non-spreading strawberry variety suitable for permanent beds. A single plant can live and produce for 5-7 years, making them far more perennial than standard strawberry varieties that require annual replacement.
