A low-growing perennial that produces sweet, red fruit in late spring to early summer — and spreads itself via runners to fill a bed over time.
Fragaria × ananassa · also called garden strawberry, cultivated strawberry

Home-grown strawberries ripen fully on the plant, developing sugars that commercially harvested fruit — picked underripe for shipping — never achieves. A single planting can produce for three to four years with minimal replanting effort.
A little history. A hybrid first documented in 18th-century France, derived from crosses between a Chilean and a North American wild species. The fleshy 'fruit' is botanically an enlarged receptacle (the stem tip that swells to hold the true fruits, which are the small seeds on the surface).
Either works well — needs at least 8 inches of soil depth; containers dry out faster and need more frequent watering. In containers: 1-gallon pot per plant minimum; 2-gallon preferred. Space plants 12 inches (30 cm) apart.
Water deeply 2–3 times per week during fruiting; reduce to once a week after harvest. Water when the top inch of soil feels dry to the touch. Aim for about 1 inch per week including rain.
Side-dress (scatter fertilizer along the row and water in) once at planting, again after the first harvest flush. What to use: balanced 10–10-10 or compost; avoid high nitrogen mid-season — it promotes leaves over fruit.
Pinch off all flowers in the first year for June-bearing types to redirect energy into root development and improve subsequent yields. Remove runners (long horizontal stems that produce new plantlets) unless you want to propagate new plants.
It's ready when fruit is fully red to the cap with no white or green shoulders; gives slightly to gentle pressure; separates easily from the stem with a light twist. Pinch the stem just above the cap between thumb and forefinger and twist gently; do not pull the berry alone — leaving the cap attached extends shelf life. Harvest every 1–2 days at peak season.
Refrigerate unwashed in a single layer on paper towels for up to 3 days. Freeze whole on a tray, then transfer to bags for up to 6 months.
Plant both June-bearing (one large flush) and everbearing (smaller flushes spring through fall) types together to extend the harvest season across several months.
Mulch crowns with 3–4 inches of straw after the first hard frost to insulate against freeze-thaw cycles. Remove mulch gradually in early spring once nighttime temperatures stay above 20 °F (-7 °C).
Borage
Borage flowers over a long season and draws bees to the bed; better bee visits during bloom often mean more evenly pollinated, fuller-shaped berries. Keep it to the bed edge so it does not shade the low crowns.
Garlic
The strong smell of garlic foliage can make it harder for pests that hunt by scent to home in on a strawberry patch. The effect is modest, so treat it as a bonus alongside netting and clean picking.
Thyme
Let thyme flower along the bed edge and its tiny blooms feed hoverflies, lacewings, and small parasitic wasps whose young eat aphids and mites. It shares the same sunny, well-drained ground strawberries want.
Lettuce
Lettuce roots stay shallow and finish quickly, so it can fill the open ground of a young strawberry planting without fighting the crowns for water. Pull it before the runners spread across the row.
Spinach
A quick spring stand of spinach shades bare soil between young crowns, holding moisture and crowding out weeds until strawberry leaves close the gaps. Harvest it before it bolts (shifts from leaf growth to flowering) and shades the fruit.
Fennel
Fennel roots release compounds that stunt most garden vegetables, and its size and hunger also crowd low strawberry crowns. Grown well away in its own corner it earns space, since the flowers feed hoverflies and tiny parasitic wasps.
Tomato
Tomatoes and strawberries both host verticillium wilt, a soil fungus that browns the crown and collapses older leaves. Keep them apart, and do not set strawberries where tomatoes grew within the past three years.
Bell Pepper
Peppers carry the same verticillium wilt fungus as strawberries, and the soil stays infested for years. Give peppers their own bed and respect a three-year gap before planting strawberries on that ground.
Mustard Greens
Old companion charts have long kept strawberries away from cabbage-family crops, though no mechanism has been demonstrated. The practical reason to separate them is simpler: strawberries hold a bed for years, and mustard needs a four-year gap from its own family.
Red Russian Kale
Old charts keep strawberries and cabbage-family crops apart, though no mechanism has been shown. The practical objection is simpler: strawberries hold a bed for years, while kale wants a bed you can rotate out of brassicas every four seasons.
Cauliflower
Old charts keep strawberries away from cabbage-family crops, and no mechanism has ever been shown. The practical issue is simpler: cauliflower is a hungry, wide plant that shades and crowds a low strawberry bed you cannot easily dig around.
Cabbage
Old companion charts keep strawberries and the cabbage family apart, though no mechanism has been demonstrated. The practical reason to separate them is different bed cycles: strawberries stay put for years, while cabbage needs a four-year rotation away from its own family.
Red Cabbage
Old companion charts keep strawberries and the cabbage family apart, though no mechanism has ever been demonstrated. The practical objection is simpler: strawberry runners spread into the wide spacing cabbage needs.
Brussels Sprouts
Old charts keep strawberries and the cabbage family apart, and no mechanism has ever been shown. The practical objection is simpler: sprouts hold a bed for most of a year, and harvesting or renewing a strawberry patch underneath them is awkward.
Broccoli
Old companion charts keep strawberries and the cabbage family apart, though no mechanism has ever been shown. The practical caution is simpler: broccoli is pulled and the bed reworked each season, which disturbs a strawberry planting meant to stay put for years.
Kale
Old companion charts keep strawberries and cabbage-family crops apart, though no mechanism has been shown. The practical case is simpler: strawberries occupy a bed for years, while kale needs a four-year break from that ground.
Bok Choy
Old companion charts have long kept strawberries away from cabbage-family crops, but no mechanism has ever been demonstrated. If you separate them, do it for the practical reason: strawberry runners sprawl over a bok choy row and block airflow.
Turkish Rocket
Old companion charts keep strawberries and cabbage-family crops apart, though no mechanism has ever been shown. The practical objection is real enough: a permanent clump of this crop shades and crowds a strawberry patch that wants open sun.
Sea Kale
Old charts keep strawberries away from the cabbage family, though no mechanism has been demonstrated. The practical objection in a sea kale bed is simpler: strawberry runners creep over the crown and make cutting blanched shoots awkward.
Pistachio
Old strawberry ground is a known reservoir for verticillium wilt, which shows in pistachio as one side of the canopy wilting and dark streaks under the bark. Site the tree elsewhere rather than risk a decades-long planting.
Kohlrabi
Old charts keep strawberries and cabbage-family crops apart, with no mechanism established. A real concern is that a permanent strawberry patch cannot be rotated, which works against the 4-year gap kohlrabi needs.
Turnip
Old charts keep strawberries and cabbage-family crops apart, and no mechanism has been demonstrated. The practical reason to separate them is different: pulling turnips disturbs shallow strawberry roots and runners.
Catnip
A mature catnip mound leans over low strawberry runners and shades them out, and cat traffic through the patch breaks crowns and knocks off fruit. Keep catnip in its own spot, at least 3 feet from the berry row.
Black Raspberry
Strawberries host the same soil-borne wilt fungus as the tomato family, so an old strawberry patch is a poor site for a new bramble row. Keep the two plantings separate and allow several years between them on the same ground.
White Clover
Both plants spread by runners, and clover stolons thread straight through a matted strawberry row. Once tangled with the crowns it cannot be weeded out without lifting the plants, so keep clover to the alleys and edge it back each month.
Phacelia
Phacelia can hold a population of tarnished plant bug, and mowing the whole patch at once pushes those bugs into fruiting strawberries, where feeding causes misshapen berries. If you grow both, mow in strips and not while berries are sizing.
Tansy
Strawberry rows are low, shallow-rooted, and picked over constantly. Tansy's runners thread straight through the matted crowns, and pulling them out lifts the berry plants with them.
A perennial — it holds its spot for years, so it sits outside the annual rotation.
A perennial that holds its bed for three to four years, so there is no yearly rotation slot to fill. It feeds moderately and leaves behind a shallow mat of fine roots and straw mulch. When you finally tear the planting out, dig in compost and avoid strawberries or other rose-family crops here for three years.
