Strawberry

Fragaria × ananassa

FruitPerennialContainer-friendly Medium

Sweet and perennial — strawberries spread themselves and fruit for years. Set the crown right at the soil line, pinch the first-year flowers, and remember they won't ripen further once picked.

Growing conditions

Light
Full sun — at least 6 hours of direct light a day, and 8+ hours gives the best yields and sweetest fruit
Water
Medium
Soil
Light, well-drained sandy loam rich in organic matter; raised beds greatly help drainage and reduce disease · pH 6.0–6.5 (slightly acidic); extensions consider 6.0–6.2 ideal for nutrient uptake
When to sow
Plant in early spring as soon as the soil is workable (no longer frozen and not muddy), up to about 4–6 weeks before your average last frost. Dormant crowns tolerate light frost; plant them right away rather than letting them dry out.
Spacing
June-bearing 45–60 cm (18–24 in) apart in rows 90–120 cm (36–48 in) apart; day-neutral/everbearing 30–38 cm (12–15 in) apart
Days to maturity
June-bearers fruit the spring after planting (about 1 year); day-neutrals and everbearers can fruit 60–90 days after spring planting once first blossoms are removed
Hardiness
Hardy and grown across USDA zones 3–10; with straw winter mulch the crowns survive far colder than the leaves

How to grow it

  1. 1

    Plant the crown at exactly the right depth

    Crown depth is the make-or-break step, and it's the one gardeners most often get wrong. Soak bare-root crowns briefly, fan the roots out in a hole, and set the plant so the crown's midpoint sits right at the soil line — all the roots buried, the central growing tip exposed. Plant too deep and the crown smothers and rots; too shallow and the exposed roots dry out and die. Firm the soil and deep water right after planting.

  2. 2

    Prepare the bed and give it full sun

    Pick the sunniest, best-drained spot you have. Work 5–8 cm (2–3 in) of into the top 30 cm (12 in) of soil before planting; strawberries are shallow-rooted and reward loose, fertile ground. A raised bed is ideal because the extra drainage and airflow sharply cut crown rot and gray mold. Avoid beds where tomatoes, peppers, eggplant, or potatoes grew recently — they share verticillium wilt.

  3. 3

    Pinch off the first-year flowers

    This feels wrong but it's the single biggest yield decision. On June-bearers, or every blossom the whole first season so the plant pours its energy into roots, crown, and runners instead of a few weak berries — you'll get a far larger crop the following June. On day-neutrals and everbearers, remove flowers only for the first 6 weeks or so after planting, then let them fruit for the rest of that first season.

  4. 4

    Manage runners to build the patch

    Runners are horizontal stems that root into new daughter plants — strawberry's natural . For June-bearers grown as a matted row, let runners root in to fill the strip, then thin the daughters so plants end up about 10–15 cm (4–6 in) apart for good airflow. For day-neutrals and everbearers grown in hills, snip most runners off so the mother plant keeps fruiting instead of spreading.

  5. 5

    Mulch under the fruit and water deeply

    Tuck clean straw under the developing berries — that's where the name comes from. It keeps fruit off bare soil, blocks mud splash, and cuts gray mold and slug damage dramatically. Deep water about 2.5 cm (1 in) per week, soaking the root zone; strawberries have shallow roots and wilt fast in dry spells, especially while fruiting. Water at the base in the morning so leaves and fruit dry quickly.

  6. 6

    Feed at the right moment (not in spring for June-bearers)

    Timing matters more than amount. For June-bearers, do not in spring — a flush of soft leafy growth invites disease and gives soft berries. Instead, feed after the last harvest during summer renovation. For day-neutrals and everbearers that crop all season, feed lightly and regularly. A typical extension rate is about 0.5 kg (1 lb) of 10-10-10 per 6 m (20 ft) of row, watered in well.

  7. 7

    Mulch with straw for winter protection

    In cold zones, the crowns need a winter blanket. After several hard frosts have the plants off into dormancy — but before deep cold sets in, usually late fall — cover the patch with 5–8 cm (2–3 in) of loose straw (oat, wheat, or rye). This buffers killing cold and the freeze-thaw heaving that can lift crowns out of the soil. Don't too early, which traps warmth, blocks dormancy, and actually increases crown rot.

Gardener's notes

  • off every flower the first year on June-bearers feels like a loss, but it's the proven way to get a far bigger crop the next June — the plant builds roots and runners instead of a handful of weak berries.
  • A pale berry is a sour berry. Unlike tomatoes, strawberries don't ripen or sweeten after picking, so wait for full red color and harvest in the cool morning when sugars are highest.
  • Watch your fall timing: straw too early traps warmth, blocks dormancy, and actually raises crown-rot risk. Wait for a few hard frosts to the plants off, then cover them.

Varieties worth knowing

Honeoye
June-bearing (early). A cold-hardy northern workhorse with high yields of firm, tart-sweet berries; excels in cooler-summer zones 3–5.
Earliglow
June-bearing (early). Smaller berries but outstanding flavor and strong disease resistance (red stele, verticillium wilt); a classic home-garden pick.
Jewel
June-bearing (mid-to-late). Large, glossy, richly flavored berries; widely grown and reliable across the North and Midwest.
Allstar
June-bearing (mid). Big, firm, classic-shaped fruit with good disease resistance; productive and dependable.
Ozark Beauty
Everbearing. The most popular everbearer — two main flushes (early summer and fall), cold-hardy, good for northern and higher-elevation gardens.
Seascape
Day-neutral. Bred at UC; very productive and adaptable, fruiting through the season as long as temperatures stay below ~30°C (86°F). Great for containers.
Albion
Day-neutral. Large, firm, well-flavored fruit with resistance to verticillium and Phytophthora crown rot; a strong continuous-cropping choice.
Tristar
Day-neutral. Sweet, aromatic berries and good disease resistance; crops steadily and is a favorite for hanging baskets and small spaces.

Common problems & fixes

Gray mold (Botrytis fruit rot)
Sign: Soft, tan-brown spots on ripening or ripe berries that quickly turn into a fuzzy gray mold; fruit touching soil, other fruit, or wet leaves rots first.
Fix: This is the number-one strawberry disease. Improve airflow with proper spacing and raised beds, mulch under the fruit, water at the base in the morning so the canopy dries fast, and pick fruit promptly. Remove and discard rotten berries immediately — don't compost them — because they seed new infections.
Slugs and snails
Sign: Ragged holes chewed into ripe berries, often on the soil-facing side, with silvery slime trails nearby; worst in wet weather and dense plantings.
Fix: A common home-garden pest that rarely troubles commercial growers. Reduce hiding spots, keep the bed weeded and well-drained, and hand-pick at night. Iron-phosphate baits (e.g. Sluggo) are effective and considered safe around children, pets, birds, and wildlife — scatter them in spring and fall when slugs are most active.
Birds
Sign: Whole or partly eaten ripe berries with peck marks, fruit vanishing just as it colors up; robins and other songbirds are common culprits.
Fix: Birds are one of the most damaging garden pests on strawberries. The reliable fix is to drape the patch with bird netting (about 6 mm / 1/4 in mesh) once fruit starts coloring, secured at the edges so birds can't sneak underneath. Remove or check it as you harvest so birds don't get trapped.
Crown rot (Phytophthora / Botrytis crown rot)
Sign: Plants suddenly wilt and collapse despite moist soil, often while fruiting; cutting the crown open shows brown, rotted internal tissue instead of healthy white.
Fix: Largely a drainage and depth problem. Plant in raised beds with well-drained soil, set crowns at the correct depth (never too deep), avoid overwatering, and don't mulch too early in fall. Remove and destroy collapsed plants, buy certified disease-free stock, and rotate to a fresh site — there's no home cure once a crown rots.
Verticillium wilt
Sign: Outer/older leaves wilt, dry, and turn brown at the margins while inner leaves stay greener; plants stunt and may die, often mid-season.
Fix: A soil-borne fungus with no cure. Plant resistant varieties (Earliglow, Allstar) and certified-clean stock, and never plant where tomatoes, peppers, eggplant, or potatoes grew in the last few years, since they harbor the same fungus.

Harvest & storage

Harvest
June-bearers give one big 2–3 week flush in late spring/early summer the year after planting; everbearers crop in early summer and again in fall; day-neutrals fruit on and off all season while it stays below ~30°C (86°F). Pick only fully red, ripe berries — strawberries do NOT keep ripening after picking, so a pale or white-shouldered berry stays sour. Harvest every 2–3 days in peak season, in the cool of the morning, snapping the stem rather than tugging the soft fruit.
Storage
Strawberries are highly perishable. Refrigerate them unwashed and dry in a single layer in a breathable container; they keep best at about 0–2°C (32–36°F) for roughly 3–5 days. Don't wash until just before eating — moisture speeds mold. Discard any moldy berry promptly so it doesn't spread. Surplus freezes well: hull, spread on a tray to freeze, then bag.
