Maintain steady moisture, apply balanced fertilizer bi-weekly, manage runners if desired, mulch around plants

3

Flowering

White flowers with yellow centers appear on flower stalks above foliage; multiple flower clusters develop

Ensure adequate potassium and phosphorus, maintain consistent watering, remove diseased flowers, provide pollinator access

4

Fruiting & Harvest

Harvest Tips

Pick berries when fully red and ripe, as Satomi does not ripen further after harvest. Harvest every 2-3 days during peak season to encourage continuous production. Pick in early morning for best flavor and shelf life. Leave the green cap attached to protect the berry. Everbearing varieties like Satomi produce main flush in early summer and secondary flushes through fall.

Fun Facts

  • 🌱 Satomi is a Japanese variety developed in the 1980s and is one of the most cold-hardy everbearing strawberries, capable of surviving winters in zone 3 with mulch protection.
  • 🌱 Unlike most strawberries where seeds are on the outside, strawberry fruits are actually accessory fruits—the red flesh is the enlarged receptacle, and the true fruits are the tiny seeds on the surface.
  • 🌱 Everbearing varieties like Satomi produce multiple flushes of flowers and fruit per season, triggered by day length and temperature rather than a single spring bloom.
