The Complete Guide to Growing Strawberries: From Planting to Harvest

The Complete Guide to Growing Strawberries: From Planting to Harvest

There's nothing quite like the taste of a sun-warmed strawberry picked fresh from your own garden. These beloved fruits are not only delicious but also relatively easy to grow, making them perfect for both beginning and experienced gardeners. Whether you have acres of land or just a few containers on your patio, this comprehensive guide will walk you through everything you need to know to grow successful strawberry plants.

Understanding Strawberry Types

Before you plant, it's important to understand the three main types of strawberries, as they have different growing habits and fruiting patterns:

June-Bearing Strawberries

  • Fruiting Pattern: Produce one large crop per year, typically over 2-3 weeks
  • When They Fruit: Despite the name, they fruit in late spring to early summer (April-June, depending on your region)
  • Characteristics: Largest berries, highest overall yield, all at once
  • Best For: Preserving, freezing, jam-making
  • Popular Varieties: 'Chandler', 'Earliglow', 'Jewel', 'Allstar', 'Camarosa'

Everbearing Strawberries

  • Fruiting Pattern: Produce two to three harvests per year
  • When They Fruit: Spring, late summer, and fall
  • Characteristics: Medium-sized berries, moderate yield spread across several harvests
  • Best For: Extended fresh eating season
  • Popular Varieties: 'Ozark Beauty', 'Quinault', 'Fort Laramie'

Day-Neutral Strawberries

  • Fruiting Pattern: Produce continuously throughout the growing season
  • When They Fruit: From spring until frost, as long as temperatures remain between 35-85°F
  • Characteristics: Smaller berries, steady production rather than big harvests
  • Best For: Container growing, small gardens, continuous fresh eating
  • Popular Varieties: 'Seascape', 'Albion', 'Tribute', 'San Andreas'

Site Selection and Preparation

Choosing the Right Location

Strawberries thrive in:

  • Full sun (at least 6-8 hours daily)
  • Well-draining soil (they hate "wet feet")
  • Slightly acidic soil (pH 5.5-6.8)
  • Areas with good air circulation to prevent disease

Avoid planting strawberries:

  • Where tomatoes, potatoes, peppers, or eggplants have grown in the past 3 years (disease risk)
  • In low-lying areas where frost pockets form
  • In heavy clay soils without amendments

Soil Preparation

  1. Test your soil: Ideal pH is 5.5-6.8. Adjust if necessary with sulfur to lower pH or lime to raise it.

  2. Add organic matter: Work in 2-4 inches of compost or well-rotted manure to improve drainage and fertility.

  3. Eliminate weeds: Remove all perennial weeds before planting, as they're difficult to control once strawberries are established.

  4. Consider raised beds: Especially helpful in areas with poor drainage or heavy clay soil. Build beds 8-10 inches high and 24-36 inches wide.

Planting Strawberries

When to Plant

  • Spring planting (recommended for northern areas): As soon as soil can be worked, typically 4-6 weeks before last frost
  • Fall planting (recommended for southern areas): In zones 7 and warmer, plant in September-November for spring harvest
  • For container growing: Can be planted almost any time, but spring and fall are ideal

How to Plant

  1. Dig appropriate holes: Space holes 12-18 inches apart in rows 3-4 feet apart.

  2. Trim roots: If excessively long, trim to about 4-5 inches.

  3. Set plants at proper depth: This is crucial! The crown (where leaves emerge) should be level with the soil surface – not buried and not sitting above the soil.

  4. Fan out roots: Spread roots out in the planting hole rather than bunching them.

  5. Firm soil and water thoroughly: Eliminate air pockets around roots.

  6. Remove flowers: For spring-planted strawberries, remove all flowers for the first 4-8 weeks to encourage strong root and crown development.

Planting Systems

Matted Row System (ideal for June-bearers):

  • Plant 18-24 inches apart
  • Allow runners to root and fill in the row
  • Rows eventually form a mat about 18 inches wide

Hill System (ideal for everbearing and day-neutral types):

  • Plant 12 inches apart in staggered rows
  • Remove all runners throughout the season
  • Focuses plant energy on fruit production instead of runner production

Ongoing Care

Watering

  • Amount: 1-1.5 inches of water per week during growing season
  • Frequency: Deep, infrequent watering is better than frequent shallow watering
  • Method: Drip irrigation or soaker hoses are ideal to keep foliage dry
  • Critical periods: During fruit development and in hot, dry weather

Fertilizing

  • At planting: Mix balanced fertilizer (10-10-10) into soil before planting
  • June-bearers: Fertilize after renovation in summer and again in early spring
  • Everbearing/Day-neutral: Light fertilizer applications every 4-6 weeks during growing season
  • Avoid: High-nitrogen fertilizers, which promote foliage at the expense of fruit

Mulching

  • Types: Straw, pine needles, black plastic, landscape fabric
  • Benefits: Suppresses weeds, conserves moisture, keeps fruit clean, prevents soil splash
  • Application: 2-3 inches deep, keeping mulch away from crowns
  • Winter protection: In cold regions, apply additional mulch (4-6 inches) after ground freezes

Runner Management

  • June-bearers: Allow some runners to root in the matted row system, but thin as needed
  • Everbearing/Day-neutral: Remove all runners to focus energy on fruit production
  • Spacing: Maintain at least 6 inches between plants even in matted rows

Pest and Disease Management

Common Pests

  • Slugs: Use iron phosphate baits or diatomaceous earth barriers
  • Birds: Cover plants with netting during fruiting
  • Strawberry weevils: Maintain good garden sanitation; use row covers until flowering
  • Spider mites: Strong water spray to undersides of leaves; insecticidal soap if severe

Disease Prevention

  • Leaf spot and leaf scorch: Ensure good air circulation; avoid overhead watering
  • Gray mold (Botrytis): Keep berries from contacting soil; remove diseased fruit promptly
  • Verticillium wilt: Use resistant varieties; practice crop rotation
  • Powdery mildew: Ensure adequate spacing between plants; remove affected leaves

Harvesting and Storage

When to Harvest

  • Pick when berries are fully colored - strawberries don't continue to ripen after picking
  • Harvest in morning when temperatures are cool
  • Pick every other day during peak season

How to Harvest

  • Pick by pinching the stem just above the berry between your thumb and forefinger
  • Handle gently to avoid bruising
  • Leave the green cap on until ready to use

Storage

  • Don't wash berries until ready to use
  • Refrigerate berries in a single layer on paper towels
  • Use within 2-5 days for best quality
  • For longer storage, freeze washed, hulled berries on trays, then transfer to freezer containers

Renovating June-Bearing Strawberry Beds

After the fruiting season (usually by July):

  1. Mow or cut foliage to 1-2 inches above crowns
  2. Narrow rows to 10-12 inches wide
  3. Thin plants to 4-6 inches apart
  4. Fertilize with balanced fertilizer
  5. Water thoroughly to encourage new growth

Propagating Strawberries

From Runners

  1. Select healthy mother plants
  2. Allow runners to develop and touch soil
  3. Ensure good soil contact (pin down if necessary)
  4. Once rooted with several leaves, cut runner connecting to mother plant
  5. Transplant to new location or pot

From Seeds

  1. Collect seeds from ripe berries or purchase seeds
  2. Cold stratify in refrigerator for 3-4 weeks
  3. Sow on surface of seed-starting mix, press lightly
  4. Keep moist at 65-75°F
  5. Germination takes 2-4 weeks
  6. Transplant when seedlings have several true leaves
  7. Note: Plants won't fruit until second year

Troubleshooting Common Issues

Small or Deformed Berries

  • Possible causes: Poor pollination, frost damage, drought stress, pest damage
  • Solutions: Ensure adequate bee activity; protect from late frosts; maintain consistent moisture

Yellowing Leaves

  • Possible causes: Nutrient deficiency, leaf diseases, root problems
  • Solutions: Check soil pH; ensure adequate nutrition; improve drainage if needed

Few Berries Despite Healthy Plants

  • Possible causes: Too much nitrogen fertilizer, insufficient sunlight, overcrowded plants
  • Solutions: Reduce nitrogen; ensure 6+ hours of sun; thin plants as needed

Runners But No Fruit

  • Possible causes: Plants too young (first year June-bearers); too much shade; excessive nitrogen
  • Solutions: Remove runners to encourage fruiting; relocate to sunnier spot; reduce nitrogen fertilizer

Regional Growing Tips

Northern Regions (Zones 3-5)

  • Choose very hardy varieties
  • Spring planting is preferable
  • Provide winter protection with 4-6 inches of mulch
  • Remove mulch gradually in spring as growth begins

Southern Regions (Zones 7-10)

  • Select heat-tolerant varieties
  • Fall planting (September-November) is often more successful
  • Provide afternoon shade during hottest months
  • Focus on early-season production before summer heat

Container Growing

  • Choose day-neutral or everbearing varieties
  • Use containers at least 12 inches deep and wide
  • Ensure excellent drainage
  • Water more frequently than in-ground plants
  • Replace soil every 2-3 years
  • Protect containers from extreme temperatures

Conclusion
