Growing Strawberries: A US Guide
Grow strawberries in Zones 3–10 with proper timing, spacing, and soil pH. Covers variety types, bed systems, renovation, and year-over-year production.
Key takeaways
- June-bearing strawberries produce one concentrated crop per year in May–June; everbearing varieties produce two crops; day-neutral types fruit continuously from May through October
- Strawberries need well-draining soil at pH 5.5–6.5 and at least 6–8 hours of full sun daily for productive fruiting
- Remove all flowers from June-bearing plants in year one to build root and runner systems — this doubles or triples year-two yield
- Renovate (mow leaves, thin runners, fertilize) annually after harvest to maintain bed productivity; without renovation, yields drop 30–50% by year three
- Replace the entire bed every 3–4 years — strawberry plants decline significantly after year three due to disease buildup and runner competition
Which type of strawberry should you grow?
Three types of strawberries grow in US gardens: June-bearing (one large crop per year), everbearing (spring and fall crops), and day-neutral (continuous fruiting all season). Your USDA zone, garden size, and how you plan to use the fruit determine which type works best for your situation.
Understanding the types before planting saves a season of frustration. A gardener in Minnesota who plants day-neutral varieties expecting a big June harvest will be disappointed — day-neutral types produce small, continuous crops but never deliver the concentrated berry bonanza that June-bearing types do. Conversely, a Zone 8 gardener who needs strawberries throughout the summer heat-free season may find June-bearing types finishing before summer arrives.
| Type | Harvest pattern | Best yield | Best zones | Runner production |
|---|---|---|---|---|
| June-bearing | 1 large crop (3 weeks in May–June) | Highest (1.5–2 qts/plant/year) | 3–7 | Heavy |
| Everbearing | Spring + late summer crop | Moderate (0.8–1.2 qts/plant/year) | 4–9 | Moderate |
| Day-neutral | Continuous May–October | Moderate, spread over season | 4–9 | Light |
For most US home gardeners in Zones 4–7, June-bearing varieties are the top choice for maximum harvest weight and flavor. The concentrated single crop is ideal for making jam, freezing, and sharing large quantities.
Choosing a location
Strawberries need:
- Full sun: 8 hours minimum. This is non-negotiable. Less sun = fewer flowers = less fruit.
- Good drainage: strawberry roots die in standing water. Even 24 hours of wet feet causes root rot. Avoid low spots.
- Air circulation: dense plantings trap moisture and promote gray mold, the leading strawberry disease in the US. Space plants properly and keep runners thinned.
- Distance from nightshades: do not plant where tomatoes, peppers, potatoes, or eggplant grew in the last 3 years. These crops share Verticillium wilt fungus with strawberries, and infected soil can kill a new planting before it produces.
Soil preparation
Test soil pH before planting. This is worth the $10–$15 investment — most gardening failures with strawberries trace back to pH problems.
Target pH: 5.5–6.5. Below 5.5, aluminum and manganese become toxic to roots. Above 6.5, iron becomes unavailable, causing leaf yellowing and reduced yields. Penn State Extension’s soil testing service provides strawberry-specific amendment recommendations from a soil sample.
Amendment steps based on soil type:
| Soil type | Problem | Fix |
|---|---|---|
| Clay | Poor drainage, compaction | Add 4–6 inches of compost + coarse sand; consider raised bed |
| Sandy | Dries fast, low nutrients | Add 3–4 inches of compost; mulch heavily |
| pH below 5.5 | Too acidic | Add agricultural lime per test recommendation |
| pH above 6.5 | Too alkaline | Add elemental sulfur per test recommendation; allow 2–3 months to act |
Work amendments into the top 8–10 inches of soil. For new beds, do this 2–4 weeks before planting so amendments have time to integrate.
Planting systems: matted row vs. hill
Two planting systems dominate US strawberry production. Choose based on your variety type and garden goals.
Matted row system (best for June-bearing)
Plants are set 18–24 inches apart in rows 3–4 feet wide. Runners are allowed to root and fill in the row, creating a dense mat of plants. This system maximizes yield per square foot because daughter plants (rooted runners) become full producers by year two.
Row renovation (see below) is essential in a matted row system — without annual thinning, plants become overcrowded and disease spreads rapidly.
Hill system (best for everbearing and day-neutral)
Plants are set 12 inches apart in raised hills or mounds (actual raised soil mounds 6–8 inches high and 18 inches wide). All runners are removed as they form. Energy goes entirely into fruit production rather than runner production. This system produces higher yield per plant but requires more active management.
The hill system works well in raised beds and container situations where runner spread is impractical.
Planting step by step
- Soak bare-root crowns in water for 20–30 minutes before planting. Crowns that arrive dry need this rehydration step.
- Dig a hole wide enough to spread all roots without bunching or circling.
- Set the crown at exact soil level. The crown is where leaves emerge from the roots. Bury it and the crown rots. Leave it above soil and roots dry out. This one step causes more strawberry failures than any other.
- Spread roots downward in a fan pattern, not in a ball.
- Backfill, firming soil around the roots to eliminate air pockets.
- Water immediately. The first watering settles soil around the roots and initiates establishment.

Year one management: the foundation year
What happens in year one determines productivity for the next 3–4 years. The primary goal is building a strong root and crown system, not harvesting fruit.
Flower removal (June-bearing only)
Remove every flower that appears during the first 6 weeks after planting. A June-bearing plant that flowers in year one directs energy into fruit that reduces future productivity.
University of Vermont Extension research found that pinched June-bearing plants produced 2.1 quarts per plant in year two, compared to 1.2 quarts for unpinched plants. Pinched plants also produced 40% more daughter plants in year one — the runners that fill out the bed.
Everbearing and day-neutral varieties: remove flowers only through June 1 of year one, then allow fruit production from July onward.
Runner management
June-bearing plants produce long runners that root where they touch soil. Allow these to root freely in year one. Each rooted runner becomes an independent plant that produces fruit in year two.
Train runners to fill in gaps in the row rather than running into the aisles. Anchor runners with a U-shaped pin or small rock to direct them where you want them to root.
By fall of year one, each original plant should have produced 4–8 daughter plants. Those daughters, combined with the original plant, will be the main producers in year two.
Mulching for winter
After the ground freezes in fall (typically November in Zone 5–6), apply 3–4 inches of clean straw over the entire bed. The mulch insulates crowns from freeze-thaw cycles that can heave plants out of the soil. Remove the mulch in spring when new growth begins — usually when temperatures consistently reach 40°F during the day.
Annual renovation: the key to long-term production
Bed renovation after the June-bearing harvest is the most important maintenance practice and the most commonly skipped.
When to renovate: within 2 weeks after the final harvest, before runner production accelerates.
Renovation steps:
- Mow leaf canopy to 3–4 inches using a string trimmer or lawnmower set high. Do not cut below 3 inches or you may damage crowns.
- Rake out clippings and remove them from the bed — old leaves can harbor disease.
- Thin plants to 6 inches apart. Remove extra daughter plants by pulling. The goal is 4–5 plants per square foot, not a solid mat.
- Apply fertilizer: 1 pound of 10-10-10 per 100 square feet, broadcast over the bed.
- Water thoroughly. New leaf growth emerges within 2–3 weeks.
The renovated bed looks completely stripped in late July. By September it’s full of new growth and healthy crowns ready for the following June’s harvest. Skipping renovation drops productivity by 30–50% by year three.
Common growing problems
Gray mold (Botrytis): the most common strawberry disease in the US. Appears as gray fuzzy growth on ripe and overripe berries, especially during wet spring weather. Prevention: improve air circulation by keeping plants thinned; avoid overhead watering; harvest ripe berries promptly; remove any diseased fruit immediately.
Verticillium wilt: soilborne fungal disease. Plants suddenly wilt even with adequate water; leaves turn brown and collapse. No cure. Remove and discard affected plants; do not replant in the same location for 3+ years. Rotate to a new location.
Slugs: most damaging in early spring and during wet periods. They create irregular holes in ripe berries and eat young leaves. Iron phosphate bait (Sluggo) is effective and safe around edible plants. Apply before you see damage.
Runners consuming resources: in everbearing and day-neutral beds, remove all runners throughout the season. For June-bearing beds past year two, thin runners to prevent overcrowding.

When to replace the bed
Replace the entire planting every 3–4 years. Strawberry beds accumulate Botrytis spores, Verticillium wilt, and other pathogens in the soil over time. Renovated beds that once produced 1.5 quarts per plant typically decline to 0.6–0.8 quarts by year four.
Signs it’s time to replace:
- Yield has dropped more than 30% from peak year
- More than 20% of plants show disease symptoms during the season
- Beds have not been renovated in more than 2 years
When replacing, start the new bed in a different location. Do not plant where nightshades (tomatoes, peppers, potatoes) grew recently — the shared Verticillium wilt pathogen will infect the new planting immediately.
