Vegetative Growth
8-12 weeks (spring through early summer)Plants grow runners and expand their leaf canopy. New rosettes form along stolons. The plant develops more robust crown with additional growing points.
Decide on growing system (matted row, spaced runner, hill system). Manage runners by training or removing depending on your chosen system. Continue weeding and mulching.
Flowering
3-4 weeksFlower buds emerge from the crown on sturdy stems. Small white flowers with yellow centers appear in clusters. Flowers are self-fertile but benefit from pollinator activity.
Ensure adequate sunlight for pollinator visits. Avoid overhead watering to reduce fungal issues. Protect from late frosts if necessary. Maintain consistent soil moisture.
Fruiting & Maturation
4-6 weeksFlowers develop into green berries that gradually enlarge and turn red. Berries ripen from outside to inside, developing the characteristic Marshall flavor and firmness.
Provide straw mulch under fruit to keep berries off soil. Monitor for pests and diseases. Water consistently. Maintain leaf cover to protect fruit from sun scald.
Harvest & Post-Season
Variable; harvest 4-6 weeks, dormancy 4-5 monthsRipe berries are ready for picking. After harvest season ends, plants enter dormancy. Runners may continue to develop.
Harvest regularly every 2-3 days. Remove old leaves and runners as needed. In fall, cut back foliage and apply cold-hardy mulch for winter protection in northern zones.

Harvest Tips
Marshall strawberries are June-bearing, producing their main crop in early to mid-summer, typically in a 3-4 week window depending on climate. Harvest berries when they are fully red but still firm, preferably in the morning after dew dries. Pick with the stem attached if using for fresh eating or storage. Harvest every 2-3 days at peak season. Berries do not continue to ripen after picking, so ensure full ripeness on the plant. Gently handle to avoid bruising. Expect 1-2 pounds of fruit per plant in peak production years.
Fun Facts
- 🌱 The Marshall variety was introduced in the early 1900s and is named after its breeder or origin location. It became one of the most widely grown strawberry varieties for over a century before modern cultivars emerged.
- 🌱 Strawberries are unique fruits where the seeds are on the outside of the berry. What we call the 'strawberry' is actually the receptacle (the part of the flower stem that holds the seeds), not a true berry.
- 🌱 Marshall strawberries produce runners (stolons) that develop new plant rosettes, allowing gardeners to easily propagate new plants. A single mother plant can produce 10-15 daughter plants in one season.
