The ‘White Soul’ Alpine Strawberry (Fragaria vesca) is a distinctive variety prized for its unique fruit and growth habit. It offers a different experience compared to common garden strawberries. Part of the alpine strawberry family, it produces smaller, intensely flavored berries.
Unique Characteristics of White Soul Alpine Strawberry
The ‘White Soul’ Alpine Strawberry stands apart with creamy-white to pale yellow fruit, a result of lacking the protein that typically causes red pigmentation. This distinctive color often leads birds to overlook the berries, leaving more for the gardener. The aromatic fruits deliver a sweet taste with notes of pineapple and a classic wild strawberry essence.
These plants grow as compact, clumping bushes, typically reaching 6 to 10 inches in height and 14 to 18 inches in spread. Unlike many traditional strawberry varieties, ‘White Soul’ does not produce runners, making it suitable for contained spaces and garden edges without spreading aggressively. Its everbearing nature provides continuous fruit from late spring until the first frost, offering a prolonged harvest season.
Growing White Soul Alpine Strawberries
Site Selection and Soil Preparation
‘White Soul’ alpine strawberries flourish in locations receiving at least six hours of direct sunlight daily, though they can tolerate partial shade, especially in hotter climates. Well-draining soil rich in organic matter is optimal for their growth. An ideal soil pH for alpine strawberries is slightly acidic, ranging from 6.0 to 6.5.
Before planting, incorporate compost or other organic material into the soil to a depth of at least two feet to support their deeper root systems. This improves soil structure, drainage, and nutrient availability, creating a healthy environment for the plants. Raised beds are also an effective option, preventing waterlogging and promoting good air circulation.
Planting Guidelines
The best time to plant ‘White Soul’ alpine strawberries is in spring after the last frost. When transplanting, ensure the crown, which is where the roots and leaves meet, remains level with the soil surface to prevent rot or desiccation. Space individual plants 8 to 12 inches apart for proper air circulation and growth.
For those starting from seed, surface sowing is recommended as the seeds require light for germination. Germination can take between 14 and 48 days, typically at temperatures around 65°F. Once seedlings have developed several true leaves, they can be transplanted to their outdoor location.
Ongoing Care
Consistent moisture is important for ‘White Soul’ alpine strawberries, particularly during flowering and fruiting periods. Aim for about 1 inch of water per week, adjusting based on growing conditions and soil type. Watering at the soil level, such as with drip irrigation, helps prevent fungal diseases by keeping foliage dry.
Light fertilization with a balanced, all-purpose fertilizer every four to six weeks during the growing season supports vigorous growth and fruit production. Avoid over-fertilizing, which can lead to excessive foliage at the expense of fruit. Alpine strawberries are generally robust and less prone to severe pest and disease issues than their larger counterparts. Proper spacing and removing diseased leaves can help manage common problems like gray mold or powdery mildew.
In colder climates (USDA zones 3-5), providing winter protection is beneficial. After the ground freezes, but before temperatures consistently drop below 20°F, apply a 2 to 3-inch layer of straw or other loose organic mulch over the plants. This insulation helps protect the crowns from extreme cold and temperature fluctuations.
Harvesting and Enjoying White Soul Alpine Strawberries
‘White Soul’ alpine strawberries are ready for harvest when they turn creamy white or pale yellow, feel soft to the touch, and release a distinct, sweet aroma. The seeds on the fruit also darken when ripe, transitioning from pale green to yellow. Unlike red strawberries, color change is not the primary indicator of ripeness for this white variety.
Harvest the berries gently, as they are delicate. Picking them with a small piece of stem attached can help prolong their freshness. Regular harvesting encourages the plant to produce more fruit throughout its long season. These intensely flavored berries are best enjoyed fresh, either eaten directly from the plant or as a garnish. They also complement desserts, fruit salads, and can be used to infuse drinks, adding a tropical and pineapple-like flavor.
