Strawberries Growing Guide

Introduction to Strawberries

Strawberries (Fragaria × ananassa) are one of the most popular fruits for home gardeners, prized for their sweet flavor, vibrant color, and versatility in the kitchen. These perennial plants produce delicious berries that are perfect for fresh eating, jams, desserts, and freezing. Strawberries are relatively easy to grow and can be cultivated in garden beds, containers, or hanging baskets, making them suitable for gardens of all sizes.

Strawberry Types

There are three main types of strawberries, each with unique characteristics and growing habits:

• June-Bearing Strawberries - Produce one large crop per year in early summer. They offer the highest quality and largest berries but have a short harvest period. Popular varieties include 'Earliglow', 'Allstar', and 'Jewel'.
• Ever-Bearing Strawberries - Produce two to three harvests per year, typically in spring, summer, and fall. Berries are smaller than June-bearing types but production is spread throughout the season. 'Quinault', 'Ozark Beauty', and 'Seascape' are excellent choices.
• Day-Neutral Strawberries - Produce fruit continuously throughout the growing season, regardless of day length. They perform well in warmer climates and are ideal for container gardening. 'Albion', 'San Andreas', and 'Tristar' are popular varieties.

Planting Strawberries

Proper planting is crucial for healthy strawberry plants and abundant harvests:

Choosing Plants

When selecting strawberry plants:

• Choose certified disease-free plants from reputable nurseries.
• Look for plants with healthy green leaves and white roots.
• Avoid plants with yellowed leaves, spots, or signs of disease.
• Consider planting a mix of types for extended harvest periods.

Planting Time

The best time to plant strawberries depends on your climate:

• In cold climates, plant in early spring as soon as soil is workable.
• In mild climates, plant in fall for harvest the following spring.
• Container-grown strawberries can be planted anytime during the growing season.

Planting Method

Follow these steps for successful planting:

• Prepare soil by removing weeds and incorporating 2-3 inches of compost.
• Dig holes large enough to accommodate the roots without crowding.
• Set plants in holes with the crown (where leaves emerge) at soil level.
• Backfill with soil and firm gently around the roots.
• Water thoroughly after planting.
• Space plants 12-18 inches apart in rows 2-3 feet apart.

Soil Requirements

Strawberries thrive in well-draining, fertile soil:

• Ideal pH range is 5.5 to 6.5 for optimal growth.
• Work 2-3 inches of compost into the soil before planting.
• Ensure good drainage to prevent crown rot.
• For container growing, use a high-quality potting mix with added compost.
• Consider raised beds if your soil is poorly drained.

Watering and Feeding

Proper watering and fertilization are essential for healthy plants:

• Water regularly, providing 1-1.5 inches per week.
• Keep soil consistently moist but not waterlogged.
• Water at the base of plants to avoid wetting foliage.
• Fertilize at planting time with a balanced fertilizer.
• Side-dress with compost or a balanced fertilizer after fruiting.
• Avoid excessive nitrogen, which can promote leafy growth at the expense of fruit.

Mulching

Mulching is crucial for strawberry success:

• Apply a 2-3 inch layer of straw mulch after planting.
• Mulch conserves soil moisture and suppresses weeds.
• It keeps berries clean and reduces disease problems.
• In cold climates, mulch protects plants from winter damage.
• Pull mulch back from plant crowns in early spring.

Common Pests and Problems

Strawberries face several common challenges:

• Slugs and Snails - Feed on ripe berries. Use beer traps or iron phosphate bait.
• Spider Mites - Tiny pests that cause stippling on leaves. Use insecticidal soap or neem oil.
• Gray Mold - Fungal disease causing fuzzy gray mold on berries. Improve air circulation and avoid overhead watering.
• Strawberry Root Weevils - Larvae feed on roots. Use beneficial nematodes for control.
• Birds - Love ripe berries. Use netting to protect plants during fruiting.

Companion Planting

Strawberries benefit from certain companion plants:

• Borage - Attracts pollinators and may improve flavor.
• Spinach and Lettuce - Provide living mulch and don't compete heavily.
• Beans - Fix nitrogen in the soil, benefiting strawberry growth.
• Onions and Garlic - Help deter pests that attack strawberries.
• Avoid planting near tomatoes, peppers, and eggplant, which share similar diseases.

Harvesting Strawberries

Harvesting at the right time ensures the best flavor:

• Pick berries when fully red and slightly soft.
• Harvest in the morning when berries are cool.
• Leave about 1/2 inch of stem attached to the berry.
• Check plants every 1-2 days during peak season.
• Handle berries gently to avoid bruising.
• Refrigerate berries immediately after harvesting.

Renewing Strawberry Beds

Strawberry plants decline in productivity after 2-3 years:

• For June-bearing types, renovate beds after harvest by mowing foliage.
• Thin plants to 4-6 inches apart and remove runners.
• Fertilize and water well to encourage new growth.
• Replace plants entirely every 3-4 years for best production.
• Start a new bed in a different location to prevent disease buildup.

Container Growing

Strawberries are excellent for container gardening:

• Choose containers at least 8-10 inches deep with drainage holes.
• Use a high-quality potting mix with added compost.
• Plant 3-5 plants per container, depending on size.
• Place containers in full sun for best fruit production.
• Water more frequently than garden-grown plants.
• Fertilize monthly with a balanced liquid fertilizer.
