Why grow strawberries?
The garden strawberry (Fragaria × ananassa) is a remarkable plant — it is the first fruit to ripen each year in most home gardens, requires no specialized site or grafting, produces in its first or second season, and consists of a fruit that is, botanically, a strange thing: each "berry" is a swollen flower receptacle dotted with up to 200 tiny achenes (the actual fruits, each containing one seed) on its outer surface. The species is itself a hybrid, created by accident in eighteenth-century French gardens when North American F. virginiana and South American F. chiloens is were planted near each other. The home-grown advantage is unusually stark with strawberries: shipping-strength commercial varieties like Driscoll's are bred for firmness and shelf life, while home cultivars are bred for flavor. A truly ripe, deep red, June-bearing strawberry off your own bed tastes almost nothing like the bright pink half-ripe berries in a clamshell.
Strawberries come in three distinct types, and choosing the right one matters more than choosing a specific variety. June-bearers produce one large concentrated crop in May or June, set flower buds the previous fall in response to shortening days, and are the most productive and best-flavored type — the right choice for jam, freezing, or a single big harvest. Day-neutrals ignore day length and produce smaller berries continuously from late spring through fall, giving steady fresh eating but lower total yield and shorter productive life. Everbearers — an older category largely superseded by day-neutrals — produce two main crops, one in early summer and one in late summer.
Two things to plan for before you plant. First, strawberries are shallow-rooted perennials (most roots in the top 6–9 inches of soil), so soil preparation matters more than for almost any other fruit — loose, organic-rich, well-drained soil with a pH near 6.0–6.5 is the foundation. Second, strawberries should not be planted in ground that recently grew tomatoes, peppers, eggplant, or potatoes, which share soilborne diseases like Verticillium wilt. Beds remain productive for about three years before yields decline; rotating to fresh ground is part of the cycle, not an option.
Types of strawberries — choose your harvest style first
The biggest mistake in strawberry planning is choosing a variety before deciding how you want to harvest. Strawberry types are grown very differently from one another — different planting systems, runner management, and seasonal rhythms. Match the type to your goal first, then choose a variety within that type.
June-Bearing
One main crop, late spring–early summer- Highest total yield in a short window
- Best for jam, freezing, preserving
- Many runners — matted row system
- Requires post-harvest renovation
Day-Neutral / Everbearing
Continuous harvest, spring through fall- Smaller but repeated crops all season
- Best for fresh eating, containers, beds
- Fewer runners — hill or raised bed system
- Remove most runners to maximize fruit
Alpine (Fragaria vesca)
Small aromatic berries, very long season- Small, intensely flavored fruit
- Few or no runners — very tidy
- Excellent for edging, paths, containers
- Often day-neutral in performance
Musk (Fragaria moschata)
Old-world heirloom, exceptional fragrance- Extraordinary perfumed flavor
- Soft fruit, lower bulk yield
- Some selections need male pollinizers
- Specialty gardening — not for bulk harvest
⚠"Everbearing" vs. day-neutral — an important distinction
In nursery catalogs, "everbearing" and "day-neutral" are often used interchangeably, but they are not exactly the same. True everbearing types produce two distinct flushes — one in early summer, one in fall — with a midsummer gap. Modern day-neutral types flower and fruit continuously as long as temperatures stay moderate (below ~85°F). Most of what Raintree carries labeled "everbearing" performs in the day-neutral pattern. When in doubt, check the individual variety description.
Pacific Northwest tip
The PNW's cool summers are exceptional for strawberry flavor — berries develop slowly and concentrate sugars and aromatics in ways that warm-summer climates simply cannot match. Both June-bearers and day-neutrals thrive here. The main adaptation for west-side growers is managing the wet spring environment: raised beds or mounded rows, straw mulch under the fruit, and frequent harvesting during peak season are more important here than in drier climates.
Planting strawberries — bareroot vs. potted plants
Strawberries are sold two ways at Raintree: as dormant bareroot crowns shipped in spring, and as established plants in 4-inch pots available through the growing season. These are the same varieties — but they are planted differently, establish at different rates, and have different first-year management requirements. Understanding which you have determines how you plant.
Typically available: Early spring
Bareroot strawberries arrive as dormant crowns — a compressed, leafless or nearly leafless root-and-crown bundle, usually packed in moist material. They look unpromising but establish rapidly when planted correctly. They are the most economical way to plant in quantity and the traditional form for June-bearing matted rows.
- Before planting: if plants arrived dry, soak roots in cool water for 30–60 minutes, no longer — over-soaking harms the crown
- Prepare a hole wide enough to spread roots fully outward without bunching or circling
- Build a small soil mound in the center of the hole and drape roots over it so they fan downward naturally
- Crown depth: set the crown so its midpoint — the junction between roots and growing point — sits exactly at the soil surface (see diagram below)
- Firm soil gently around the roots to eliminate air pockets; water thoroughly
- Keep evenly moist until new growth emerges — bareroot crowns have no stored water and will desiccate quickly if the soil dries out
- New leaves usually emerge within 1–3 weeks in warm soil
4-inch potted plants — established
Typically available: Spring through summer
Potted strawberries are actively growing plants with an established root ball and visible foliage. They transplant more easily than bareroot, establish faster, and are more forgiving of imperfect conditions — but they still require careful attention to crown depth, which is the single most common planting mistake regardless of plant form.
- Water the pot thoroughly an hour or two before planting so the root ball holds together and the plant is well-hydrated going into the ground
- Dig a hole slightly wider than the root ball and the same depth — do not over-deepen
- Remove the plant from its pot gently; avoid disturbing the root ball more than necessary
- Crown depth: set the plant so the crown — the growing point at the base of the leaves — sits at the same level it was in the pot, at or just above the soil surface. Do not bury the crown deeper than it was growing
- Backfill and firm the soil around the root ball; water in thoroughly to eliminate air pockets
- Do not mulch directly against the crown — mulch around the plant, keeping a small gap around the crown itself
- Potted plants will often begin flowering within a few weeks of transplanting
Crown depth — the most important planting detail
The crown is the compressed growing point between the roots and the leaves. Every leaf, flower, runner, and root originates here. Crown depth is critical — errors in either direction cause plant death or poor establishment, regardless of whether you're planting bareroot or potted plants.
✓ Correct depth
Crown midpoint sits at the soil surface. Roots are fully buried, growing point is exposed and visible. This is correct for both bareroot and potted plants.
✗ Too deep
Crown is buried below the soil line. Soil and mulch around the crown causes rotting, smothers the growing point, and kills the plant — often within days in wet conditions. The most common fatal planting mistake.
âš Too shallow
Crown and roots are too high — roots are exposed to air and dry out rapidly. Plants wilt, fail to anchor, and establish poorly. Always easier to correct than planting too deep: add soil and firm it gently around the base.
⚠Critical — blossom removal in the first season
For bareroot June-bearing plants in their first year, remove all blossoms for the first 4–6 weeks after planting. This redirects energy from fruit production into root and crown development, resulting in a much stronger planting and a far better harvest in year two. For day-neutral plants in pots — already established — you can allow the first flush of blossoms to fruit, though some growers remove the first wave to build plant strength. For bareroot day-neutrals, treat like June-bearers and remove early blossoms.
Pacific Northwest tip
In the PNW's wet spring climate, crown depth is even more critical than in drier regions. A crown planted even slightly too deep in consistently moist maritime soil will rot within weeks. When in doubt, plant very slightly proud of the soil line — a crown sitting a few millimeters high is easily corrected with a little backfill, while a buried crown in wet PNW soil is almost impossible to recover. Raised beds make crown depth management considerably easier because you're working in loose, well-drained growing medium rather than heavy native soil.
Growing systems — match the method to the type
Strawberries are unusually flexible about how they're grown. The right system depends on the type you're growing, the space you have, and whether your soil drains well or tends to stay wet. In general: June-bearers go in matted rows; day-neutrals and everbearers go in hills or raised beds; alpines go anywhere.
Matted row system
Best for: June-bearing strawberries- Space plants 18–24 inches apart in rows 3–4 feet apart
- Allow runners to root and fill the row over the first season
- Produces the highest total yield from a June-bearing bed
- Renovate the bed immediately after harvest in mature plantings
- Needs more space but is very productive over 2–4 years
Hill system / raised beds
Best for: Day-neutral, everbearing, container- Remove most or all runners to keep plants focused on fruit
- Space plants 12–15 inches apart in a grid or offset pattern
- Raised beds dramatically improve drainage — essential in wet climates
- Mulch heavily to keep fruit off soil and reduce rot
- Plants typically replaced after 1–2 seasons in intensive hill systems
Containers and patio growing
Best for: Day-neutral, alpine, small spaces- Use pots with strong drainage — strawberries hate waterlogged roots
- A minimum 10–12 inch depth is recommended for good root development
- Water more frequently than in-ground beds — containers dry faster
- Feed lightly every 2–3 weeks during the growing season
- Move containers to shelter in winter in colder zones
Groundcover / edible landscape
Best for: Alpine, some day-neutral- Alpine strawberries with no runners are excellent for edging paths and beds
- Lower total yield than dedicated beds — accept that tradeoff
- Very low maintenance once established
- White and yellow alpine varieties are less attractive to birds
A note on Marshall strawberries
The Marshall strawberry has an unusual Pacific Northwest story. Discovered in Massachusetts before 1900, it became a defining commercial variety in the Pacific Northwest and developed a legendary regional reputation for flavor before virus pressure and the demands of industrial shipping pushed it aside in favor of firmer, more storable modern types.
Marshalls are not for everyone. The fruit is soft, deeply aromatic, intensely flavored, and entirely unsuited to shipping or sitting on a store shelf. What they are suited for is exactly what home growers and local farm stands are positioned to offer: fruit picked and eaten at its absolute peak. A ripe Marshall strawberry is among the most memorable experiences in a home garden.
Pacific Northwest tip
Marshall is best grown in the PNW where its soft fruit and short shelf life are advantages rather than liabilities — you pick it, eat it the same day, and experience something grocery stores simply cannot offer. Plant Marshall bareroot crowns in a dedicated matted row, manage carefully for virus-free stock, and treat the planting as a 2–3 year rotation using runners from healthy plants only.
Watering, fertility, and mulch
Strawberries have shallow roots and need consistent moisture to produce well — the target is approximately 1 inch of water per week during the growing season, though sandy soils, containers, and hot weather often require more. The most critical window is during bloom and fruit sizing; allowing plants to dry out during flowering directly reduces fruit set and size.
Drip irrigation or soaker hoses are strongly preferred over overhead watering. Keeping foliage and crowns dry significantly reduces gray mold pressure — particularly important during bloom, when fungal infections that start in flowers are invisible until they appear as rotting fruit weeks later. In containers, water deeply until excess drains freely, then allow the top inch to dry before watering again.
Fertilize lightly and consistently rather than heavily. Excess nitrogen produces lush foliage at the direct expense of fruit and increases disease susceptibility. A light application of balanced fertilizer in early spring, and a follow-up feeding timed to the system — after renovation for June-bearers, or mid-season for day-neutrals with a long cropping window — is generally sufficient.
Mulch is one of the most important tools in strawberry growing. It suppresses weeds, keeps berries off bare soil, moderates soil temperature, and reduces the rain-splash that spreads disease from soil to leaves and fruit. Maintain 2–3 inches of straw, pine needles, or clean bark mulch under and around plants throughout the season, keeping a small gap immediately around each crown.
Pacific Northwest tip
In western WA and OR, west-side strawberry plantings often receive adequate moisture through June from rainfall alone. Summer irrigation becomes critical in July and August, especially during the dry season. Overhead watering during PNW's cool, humid mornings creates ideal gray mold conditions — if you use sprinklers, switch to early-morning timing so foliage dries before evening. Drip is strongly preferred for any planting where gray mold has been a problem.
Harvest
Strawberries do not improve in flavor after picking — they must be harvested fully ripe. Pick fruit when it has developed complete, even color all the way to the tip. Pinch or snip the stem rather than pulling the berry, which can damage the crown. During peak production, check beds every 1–3 days; in warm weather, a berry can go from perfect to overripe in 24 hours.
Frequent harvesting is one of the most effective pest and disease management strategies available. Overripe berries left in the bed feed gray mold, spotted wing drosophila, slugs, and birds simultaneously. Refrigerate harvested fruit promptly — strawberries hold their quality for only a day or two at room temperature.
Pacific Northwest tip
During rainy stretches in peak PNW strawberry season (typically late May–July), harvest every day if possible. Wet conditions accelerate gray mold from invisible blossom infections to visible rotting fruit within 48 hours. A few minutes of picking every day beats a once-a-week harvest where half the crop is lost to mold. This is especially true for soft heritage varieties like Marshall.
Common problems
Gray Mold (Botrytis)
High — PNW West Side
Caused by Botrytis cinerea, gray mold is the most significant strawberry disease in cool, wet climates including maritime PNW. Infections begin invisibly in open blossoms during wet or humid weather, then manifest as soft brown rot and fuzzy gray sporulation on ripening fruit. The bloom-to-symptom gap of 2–3 weeks means a rainy bloom period reliably leads to mold problems at harvest — even if harvest weather is dry.

- Improve airflow through wider spacing, runner control, and annual replanting
- Use drip or soaker irrigation — never overhead watering during bloom
- Mulch heavily to keep fruit off bare, wet soil
- Harvest every 1–2 days during peak season; remove any infected fruit immediately
- Fungicide sprays timed at early bloom can protect blossoms in high-pressure years
Pacific Northwest tip
West of the Cascades, treat gray mold prevention as a primary design constraint — not an afterthought. Raised beds, wide plant spacing, straw mulch, and drip irrigation are not optional extras here; they are the core management system. Dense, flat in-ground plantings with overhead watering will struggle with Botrytis every wet season.
Spotted Wing Drosophila (SWD)
High — PNW
Drosophila suzukii, unlike common fruit flies, uses its serrated ovipositor to lay eggs in intact ripening fruit — not just overripe or damaged berries. Larvae are tiny white maggots found inside otherwise normal-looking strawberries. SWD arrived in the PNW around 2009 and has become a major pest of all soft fruits.

- Harvest frequently — ripe fruit on the plant is the primary egg-laying site
- Refrigerate harvested fruit immediately to halt larval development
- Remove and destroy overripe or damaged fruit — do not leave it in or near the bed
- Monitor with SWD-specific traps (apple cider vinegar + red wine bait) to track population peaks
- Fine-mesh exclusion netting (under 1mm openings) is the most effective non-chemical protection for home plantings
Pacific Northwest tip
SWD is one of the most significant strawberry pests PNW home growers face and is not mentioned in many older guides. Pressure typically peaks from late June through August. If you've found maggots in apparently healthy-looking ripe strawberries, SWD is the most likely culprit. Daily harvest and quick refrigeration are the most practical controls for home growers.
Slugs
High — Wet Gardens
Slugs feed at night, rasping ragged holes in ripening berries. They thrive under the combination of mulch, moist soil, ripe fruit, and dense canopy that makes a mature strawberry bed. Damage is often worst where fruit rests directly on soil or wet mulch and where harvest is infrequent.
- Harvest frequently — ripe fruit on the soil surface is the primary feeding site
- Use straw mulch to keep fruit off the ground while still minimizing slug habitat
- Apply iron phosphate bait (Sluggo) around beds — effective and safe around pets and wildlife
- Trap slugs with boards or inverted pots placed near beds; collect and dispose in the morning
- Avoid leaving clumps of wet debris and old mulch where slugs overwinter
Root & Crown Rot / Red Stele
High — Poor Drainage Sites
Crown rot (Phytophthora cactorum) and red stele root rot (Phytophthora fragariae) both thrive in saturated, poorly drained soil. Affected plants show sudden wilting, stunted growth, yellowed leaves, and in severe cases complete collapse. Red stele is identifiable by the characteristic reddish discoloration of the central root core when cut open. These diseases are almost always linked to the wrong site rather than the wrong variety.
- Plant in raised beds whenever drainage is questionable — this is the single most effective preventive measure
- Avoid areas where water stands after rain, even briefly
- Do not bury crowns — saturated soil around a buried crown is the fastest route to crown rot
- Replace severely affected plantings in clean, well-drained soil; some Phytophthora strains persist in soil for years
- Choose varieties with documented red stele resistance when replanting affected sites
Birds
Moderate to High — Timing-Dependent
Birds, particularly robins and starlings, can strip a small strawberry patch nearly overnight once fruit begins to color. The damage often seems to happen suddenly because birds key on color — a bed with a few red berries one morning can be significantly stripped by afternoon.
- Net before fruit begins to color — waiting until the first berries turn red is often too late
- Use lightweight bird netting supported on hoops or a frame so berries aren't accessible through the mesh
- Check netting regularly for birds caught inside; secure edges to the ground
- White and yellow alpine varieties are naturally less attractive to birds and need less netting
Seasonal care calendar
Winter
Dec - Feb
- In colder zones (5 and below): protect crowns with 2–4 inches of straw mulch once plants are fully dormant — avoid smothering plants that are still growing
- In mild maritime PNW: clean up old foliage, remove debris, and assess bed condition
- Plan new beds and order certified disease-free plants early — popular varieties sell out
- Prepare raised bed structures if installing new plantings in spring
Early Spring
Mar - Apr
- Plant bareroot crowns as soon as soil is workable — strawberries prefer cool planting conditions
- Pull winter mulch back gradually as growth resumes; leave some in place for light frost protection
- Apply light balanced fertilizer to established beds
- Weed early and thoroughly — weeds are easiest to remove before they establish
- Set up drip irrigation or soaker hoses before bloom begins
- Set out potted plants anytime once risk of hard frost has passed
Pacific Northwest
PNW bareroot strawberries are typically planted March–April. The cool, moist conditions are ideal for establishment. Avoid planting when soils are waterlogged — allow them to drain and dry slightly before working and planting.
Bloom & Late Spring
Apr - Jun
- Bareroot June-bearers (planting year): remove all blossoms for the first 4–6 weeks to build plant strength
- Established beds:Â allow all blossoms to develop; avoid sprays during open bloom to protect pollinators
- Switch to drip irrigation if you've been using overhead watering — bloom is the highest-risk window for gray mold
- Place straw mulch under developing fruit to keep berries off soil
- Set out bird netting before fruit begins to color
- Begin SWD monitoring with traps in late May
Summer Harvest
Jun - Aug
- Harvest June-bearers every 1–2 days during peak season; refrigerate immediately
- Harvest day-neutrals every 2–3 days throughout the season
- Remove overripe, damaged, or moldy fruit from the bed at every harvest
- Water consistently — do not let plants dry out during peak fruiting
- Control runners on day-neutral plantings to keep plants focused on fruit
- Allow runners to root and fill gaps in June-bearing matted rows
Pacific Northwest
SWD pressure peaks July–August in the PNW. Daily harvest and immediate refrigeration are the most practical controls. If pressure is high, consider fine-mesh exclusion netting over ripening beds — especially for soft-fruited varieties like Marshall that are particularly vulnerable once egg-laying begins.
Renovation
June-bearing beds only — July
- Applies to mature June-bearing beds only — not planting-year beds and not day-neutral systems
- Immediately after harvest: mow foliage to 3–4 inches above the crowns — do not cut into the crowns
- Narrow rows to 8–12 inches with a hoe or tiller, removing crowded plants
- Apply a light balanced fertilizer to support regrowth
- Water thoroughly so regrowth begins quickly — this is critical for next year's flower bud formation
- Weed the renovated bed while it is open and accessible
Fall
Aug - Nov
- Keep beds watered if autumn is dry — flower buds for next year's June-bearing crop form in late summer and fall
- Root selected runners from healthy mother plants for replacement beds; use only from virus-free stock
- Remove diseased plant debris from beds to reduce overwintering inoculum for gray mold and other diseases
- In zones 5 and below: prepare winter mulch once plants enter dormancy
- Evaluate bed performance — plan replacement of beds entering their third or fourth year

âš Always source certified virus-free plants
Strawberries are highly susceptible to several persistent viral diseases (strawberry mild yellow edge virus, strawberry crinkle virus, and others) that reduce productivity and spread through runners. Always purchase certified virus-tested, disease-free planting stock from reputable nurseries. Never propagate runners from plants of unknown virus status, particularly heritage varieties like Marshall that were historically plagued by virus buildup. Starting each new bed with clean stock from a reliable source is the single most important decision for long-term strawberry productivity.
