Vegetative Growth
4-6 weeksPlant develops runner formation and expanded foliage. Multiple crowns may form from the parent plant.
Decide whether to allow runners to root or pinch them off. For potted production, allow 1-2 runners to develop. Water regularly and fertilize every 3 weeks with balanced fertilizer.
Early Flowering & Fruiting
3-4 weeksFirst flower buds appear and develop into white or pale pink blossoms. Early berries begin forming.
Provide consistent water as fruit development is demanding. Ensure pollinators have access (bees are ideal). Remove any damaged or deformed berries early.
Peak Production
8-12 weeksContinuous flowering and fruiting occurs throughout summer and fall. Multiple fruit stages visible simultaneously on the plant.
Harvest ripe berries every 2-3 days to encourage continued production. Maintain consistent watering and apply light fertilizer every 2-3 weeks. Deadhead spent flowers to redirect energy.
Fall & Dormancy
4-8 weeks depending on climateProduction slows as temperatures drop. Foliage may turn reddish and growth diminishes as frost approaches.
Harvest remaining berries before hard frost. In zones 3-5, apply 2-4 inches of straw mulch after ground freezes for winter protection. In mild climates, production may continue through winter.

Harvest Tips
Harvest berries when fully red and slightly soft, typically in early morning when firm. Pick every 2-3 days during peak season to encourage continuous flowering. Glaskin's Perpetual produces fruit from June/July through October in most climates. For everbearing types, allow some early runners to develop into new plants for next season's production. Use immediately or refrigerate; freeze or preserve for later use.
Fun Facts
- 🌱 Glaskin's Perpetual was developed in England in the early 1900s and remains one of the most reliable everbearing varieties for home gardeners, still commercially available over 120 years later.
- 🌱 Strawberries are the only fruit whose seeds grow on the outside; each of the tiny dots on a strawberry is technically a separate fruit containing a single seed.
- 🌱 Unlike many everbearing varieties, Glaskin's Perpetual produces runners prolifically, making it excellent for natural propagation and establishing new productive plants each season.
