Places to Grow Strawberries in the U.S.

Site Selection

• Strawberry plants are most productive when placed in full sunlight. They prefer well-drained, fertile soil with a pH between 6 and 6.5. Sandy loam soil is best. Avoid growing strawberries five or more consecutive years in one place. The longer plants remain in a fixed site, the more likely they are to develop a root disease from herbicide treatments. Also, avoid sites previously used to grow tomatoes, potatoes, peppers or eggplants. These plants commonly harbor root rot fungus which can devastate strawberry plantings.

Climate Growth Differences

• Strawberry growing practices vary significantly depending on climate. In the northern U.S., strawberries are planted early in the spring. Plants are then well-established prior to hot summer months and the cold winter. In southern states and California, where winter snow is not a concern, fall planting is more common. Soil borne disease and pests are prevalent in warm climates. Consequently, strawberries are typically grown like an annual. In the northern U.S. strawberry plants typically last three to five consecutive years. To protect from freezes or snow, plants should be covered by a layer of mulch in December, after they go dormant.

Annual Growth Cycle

• Temperature and daylight duration will influence strawberry growth patterns. Long days and warm summer temperatures encourage strawberry runner growth. Short, cooler fall days promote flower formation. Flower clusters develop inside the plant crown, waiting until spring and the return of temperate weather to emerge. Berries start to ripen approximately a month after flowers open. In southern climates, flowers develop soon after fall planting. Plants are destroyed soon after each spring bloom and harvest.

Plant Selection Consideration

• Growers are consistently trying to improve berry taste, size, disease-resistance, hardiness and productivity through the introduction of new plant varieties. With so many varieties to choose from, it can be difficult to select just one. Take into account the location where the strawberry plant will be grown. For example, disease resistance is a higher priority in wet soil where crop rotation is limited. The degree of hardiness will take precedence in cold, northern climates. Most home growers and u-pick farmers will consider the flavor of the fruit very important. For the best results, don't forget to select a variety that's well-adapted to your region.
