Strawberries (Fragaria x ananassa) — Herbaceous perennial.
This crop carries an unusually heavy problem load: 4 diseases, 5 pests and 4 nutrient issues are documented for it, so most of the effort in growing it well goes into prevention.
Core growing advice on this page is checked against named horticultural and university-extension sources — see References.

At a Glance
When to plant in the USA
United States. Strawberries are planted as dormant bare-root crowns in early spring, and Utah State is explicit that because the plants are dormant there is no need to wait until the risk of spring frost has passed — so this crop does not time off the frost date the way a transplanted vegetable does. Set the crown so only the roots and its base are covered, leaving as much of the crown above ground as possible; planting too deep is the commonest cause of failure. Matted row: 18-24 in apart with rows 3-4 ft apart. Annual hill: 12-15 in apart in staggered rows. June-bearers give their first real crop in the spring of the second growing season. The frost risk that does matter comes later — open blossoms are killed by late spring frost, taking the earliest and largest berries with them, so cover blooming plants on cold nights.
Soil & Growing Conditions
Growth Stages
| Stage | BBCH | Notes |
|---|---|---|
| Establishment | 0 | Grow from runners (bare-root or cold-stored) or pot-grown plants rather than from seed. Plant with the base of the crown resting right at the soil surface: bury the crown and it rots, set it too high and the roots dry out (RHS). Space plants about 35-40cm (14-16in) apart in rows about 75cm (30in) apart, or about 20cm apart in containers (RHS); matted-row systems set plants wider and let runners fill in (Ohio State). Choose a sunny, sheltered site with fertile, moist but free-draining soil enriched with well-rotted compost, and avoid ground where strawberries, potatoes or tomatoes grew recently because they share verticillium wilt. Planting in late summer or early autumn (Aug-Oct) establishes plants before winter for a full crop the following June; spring planting gives a lighter first-year crop. Water in well and keep moist while establishing (time to a first full crop is about 1-2 years). |
| Vegetative Growth | 1 | Plants form a low rosette of trifoliate leaves and send out runners (stolons) that root into new plantlets. Remove unwanted runners through the season to prevent overcrowding and keep energy in the parent plant; peg down a few healthy runners in late summer if you want new plants for next year (RHS). Water regularly in dry spells, watering in the morning and keeping water off the crown, and keep beds weed-free. On spring-planted strawberries, pinch off the first flush of flowers in the first year so the plant builds strong roots and leaves before cropping (Ohio State first-year blossom removal). |
| Flowering | 6 | White (sometimes pink-flushed) flowers open in spring, typically April to May, and are pollinated by bees and other insects; good pollination gives well-shaped berries (RHS). Flower buds and open flowers are frost-sensitive, so cover plants with horticultural fleece overnight when spring frost is forecast and remove it by day so pollinators can reach the flowers (RHS; Met Office notes late frosts remain a UK risk into spring). As the first flower buds form, switch from a balanced feed to a high-potassium (tomato-type) feed to support fruiting rather than leafy growth. |
| Fruit Development | 7 | Fertilised flowers swell into green berries that enlarge and begin to colour. Tuck a layer of straw (the origin of the name strawberry) or strawberry mats under the developing fruit once berries form, to keep them off damp soil and reduce grey mould and slug damage (RHS). Water consistently while fruit is swelling because irregular watering causes small, misshapen or split fruit, but avoid wetting the ripening berries. Net plants or use a fruit cage as berries start to colour, since birds are the single biggest threat to a UK strawberry crop (RHS). |
| Ripening / Harvest | 8 | Pick berries when they are bright red all over, ideally during the warmest part of the day when flavour is best, checking plants every 2-3 days at the peak (RHS). June-bearing types crop heavily over about 2-3 weeks from late May or June; everbearing and day-neutral types crop in smaller flushes from summer into autumn (Ohio State; OSU Extension). Strawberries are highly perishable, so eat or refrigerate them promptly and freeze or make jam with any surplus. |
| Senescence / Dormancy | 9 | After the main summer harvest, renovate the bed: cut old foliage back to about 10cm, remove the straw mulch and any diseased leaves, and give a light feed to drive strong new growth for next year (RHS). Take the straw off in autumn so it does not harbour fungal diseases, slugs and snails over winter (RHS). Strawberries are hardy (RHS H6, about -20 to -15C) and go dormant over winter, but yield declines after about three to four fruiting years, so start a fresh bed in a different spot using runners from your healthiest plants (RHS; Ohio State). |

Tier 1. US extension source: dormant bare-root plants are transplanted in early spring and, being dormant, need no wait for spring frost risk to pass; cover only the roots and the base of the crown, leaving as much crown above ground as possible; matted row 18-24 in in the row with rows 3-4 ft apart, annual hill 12-15 in staggered; June-bearers crop in the spring of the second growing season; blossoms are susceptible to late spring frost and should be covered on cold nights; irrigate every 3-5 days in summer heat; renovate immediately after harvest.

Frequently Asked Questions
How long do strawberries take to grow?
Typically 180–270 days, depending on cultivar and growing conditions.
What soil pH do strawberries need?
A pH of about 5.8–6.5. That span reflects genuine variation between the authorities we cite rather than a single agreed figure — the References section lists each source's exact range.
What problems affect strawberries?
Our data links 4 diseases and 5 pests to this crop. See the sections above for each one and how to manage it.
Plan next season before the problems start
Almost everything on this page resolves to your own frost dates rather than the calendar — the last spring frost moves by roughly two months between zone 3 and zone 10. The USA Garden Planner works from your zone so the timing is already decided before the season starts.
