Strawberries are a highly sought-after perennial fruit, offering a rewarding harvest for a relatively small effort. Success depends entirely on planting at the right time in your specific climate zone. USDA Hardiness Zone 7a, defined by average minimum winter temperatures between 0°F and 5°F, provides a long enough growing season for many varieties. Proper timing ensures plants establish a strong root system before summer heat or winter, leading to abundant fruit production.
Optimal Planting Times for Zone 7a
Planting in Zone 7a offers two primary windows, each with distinct advantages. Most growers choose the early spring window, typically late March through April, as soon as the soil is workable. This timing allows bare-root plants to break dormancy and begin active growth once the soil temperature is consistently above 40°F, before the high temperatures of summer arrive.
Bare-root crowns must be planted immediately upon receipt in early spring, as they are dormant and ready to be stimulated by the warming ground. Delaying planting risks the crowns drying out or breaking dormancy prematurely. This spring method is most common for establishing a new strawberry bed, especially for plants that will not be allowed to fruit in their first year.
An alternative approach in Zone 7a is late-fall planting, usually in late November or early December. Fall planting gives the crowns a head start, allowing root systems to establish slowly throughout the winter dormancy period. This means plants are prepared to begin vigorous top growth as soon as the soil warms in spring, potentially leading to a more substantial second-year harvest.
The key to successful fall planting is ensuring the crowns are in the ground at least a month before the first hard freeze, generally expected in mid-November for this zone.
Selecting Strawberry Types for Success in Zone 7a
Understanding the growth habits of different strawberry types maximizes success in the Zone 7a climate. Strawberries are categorized into three main types based on their fruiting pattern: June-bearing, Everbearing, and Day-neutral. June-bearing varieties produce a single, large crop over a two-to-three-week period, typically in late spring or early summer.
June-bearing strawberries are well-suited to Zone 7a because they benefit from the distinct seasonal chill periods necessary for flower bud formation. Cultivars like ‘Earliglow’ and ‘Chandler’ perform well here, known for their excellent flavor and reliable production. These types also produce numerous runners, making them ideal for the matted row system.
Day-neutral strawberries are a viable option, producing fruit continuously throughout the growing season, provided temperatures stay between 35°F and 85°F. Varieties such as ‘Albion’ and ‘Seascape’ handle the warm summers of Zone 7a while producing a steady supply of berries. Everbearing varieties are similar but typically produce two smaller crops, one in spring and one in late summer.
Essential Planting and Initial Care Steps
Planting the strawberry crown is the most important step for ensuring the plant’s survival and future productivity. Strawberry plants thrive in well-drained soil with a slightly acidic pH range, ideally between 5.3 and 6.8. Amending the site with organic matter, like compost, before planting improves drainage and nutrient retention.
When setting the bare-root crown into the ground, it must be planted at the correct depth. The crown, the central part of the plant where the leaves emerge, must be set precisely at soil level. Planting too deep will bury the crown, leading to rot, while planting too shallow can cause the roots to dry out and the plant to fail.
Spacing is determined by the variety chosen. June-bearing types are often planted in a matted row system, spaced 18 to 24 inches apart within the row to allow runners to fill the space. Day-neutral and everbearing varieties are better suited to the hill system, spaced 10 to 12 inches apart, and runners are removed to focus energy on fruit production. Following planting, the area must be watered thoroughly to settle the soil around the roots and eliminate air pockets.
For spring-planted June-bearing varieties, the first year’s flower buds must be removed as soon as they appear. This practice, known as de-blossoming, forces the young plant to direct energy into developing a strong root system and more crowns. This foundational development ensures a significantly larger and more vigorous harvest in the second and subsequent years.
