When to plant strawberries in Hawaii.
Sow or transplant between Dec 18 to Jan 22 in a typical year, keyed to Hawaii's median last frost around Jan 1. A second, fall sowing fits Nov 1 to Dec 1. Dates below are state medians; your ZIP code shifts them by days to weeks.

Strawberries dates for a typical Hawaii season.

Dec 18 to Jan 22
Keyed to the ~Jan 1 last frost. Sow 0" deep, 12" apart.
Fall round

Hawaii spans more than one climate: Zone 12 is the most common zone, but the state runs 12a to 12a. That's why the planner works from your ZIP code's frost dates, not your zone: mountain and coastal gardens in the same state can be three weeks apart.
Hawaii growing notes
Day-neutral is the only kind of strawberry that makes sense on a calendar with no cold snap, which makes it the sensible choice here without making it a safe one.
Why this crop is scheduled as day-neutral and not the classic kind
Strawberry crowns here are set essentially at the soil surface, spaced about 12 inches apart, with a first picking around 90 days out and a modest return, roughly a pound and a half per plant, across the run. The classic strawberry needs a real cold stretch to trigger strong flowering; deprived of it, a plant like that spends its energy throwing runners instead of setting fruit, and the flowers that do show up thin out to almost nothing. Zone 12a never delivers a cold stretch, sentinel dates on the calendar or not, so the type scheduled here is day-neutral, bred to flower and fruit on its own clock rather than waiting on cold that isn't coming.
A day-neutral variety still throws runners, just fewer than a classic type would, and left alone they pull energy from the mother plant toward daughters crowding the row. Snapping runners off close to the crown as they appear keeps that energy in the berries instead. Young runner growth is also where aphids cluster first, so a runner check doubles as a pest check; a small colony knocked back with a strong water spray is easier than one already spread into the flower trusses.
Warmth sets the ceiling, and the plant says when it has hit it
With no frost to force a dormant season, and both a spring and a later window scheduled, strawberries here behave more like a fruiting perennial than the one-and-done planting some other crops on this calendar are. That does not make them easy. Strawberries have a comfortable middle band of growing weather, and the plants stop growing once conditions run past either end of it; on a calendar with no cold snap, only the warm end is ever in play. Day-neutral types carry a caution of their own, having been bred for steady flowering rather than for heat endurance, and they may not perform well in warmer regions.
So watch the crown rather than the fruit. Note where the newest unfurled leaf sits on a marked plant, then look at that same plant a week later. Fresh growth pushing out of the center means the plant is still working; nothing new through a warm stretch means it has stalled, and the cause is the weather rather than the watering can. Running that check across both windows decides whether the later planting earns more bed space or less.
A fruit fly with no offseason here to slow it down
Spotted wing drosophila is the pest most worth watching, with no offseason to ease the pressure a mainland patch gets a break from; what sets it apart from an ordinary fruit fly is timing. It lays eggs in fruit still ripening on the plant, not in fruit already soft or dropped, so waiting for overripe berries to show a problem misses the window. The check is cutting open a few just-ripe berries and looking for tiny white larvae in the flesh, or dissolving salt into a cup of water, dropping in a handful of ripe berries, and watching for larvae to float out over the next half hour. Picking every ripe berry on schedule, rather than letting a few hang an extra day, removes the fruit this pest is after.
Gray mold shows up on the fruit itself here, while powdery mildew stays up on the leaves instead. Gray mold is a soft brown spot that turns fuzzy and gray fast, usually starting wherever a berry sits against wet soil or mulch, and a layer of straw under the fruit breaking that contact cuts the risk down. Powdery mildew shows instead as a white film across the leaf top that curls younger leaves at the edges; thinning crowded foliage so air moves under the plant helps against both, even though neither has anything to do with temperature here.
In Hawaii: watch for
The pests that find strawberries here.
With about 364 frost-free days, strawberry, day-neutral spends longer in the ground here than in most of the country, which widens the window in which spotted wing drosophila can find it. Scout weekly from midseason and act on the first signs.
Soft, quickly-rotting ripe berries with tiny larvae inside.
Organic fix: Pick often, chill fast, hang traps, exclude with fine netting.
Chinese rose beetle
Leaves chewed to lace between the veins, with no insect in sight by day.
Organic fix: Go out after dark with a jar of soapy water and pick them off, or hang a dim light over a soapy tray to trap them.
White powder on leaves, or fuzzy gray rot on the fruit.
Organic fix: Prune for airflow, water at the base, spray neem.
Your season math: Hawaii gives strawberries about 364 frost-free days, and it needs roughly 90 days to a first harvest. It's a one-planting crop, so time that single sowing well.
Planting strawberries in Hawaii: questions
When should I plant strawberries in Hawaii?+
In a typical Hawaii year, sow strawberries or set out transplants between Dec 18 to Jan 22, keyed to the state's median last frost around Jan 1. There's also a fall window: Nov 1 to Dec 1. Your exact dates shift with your ZIP code and microclimate.
When do I start strawberries seeds indoors in Hawaii?+
Start seeds inside about 6 weeks before set-out: roughly Nov 6 to Dec 11 for a typical Hawaii season.
What USDA zone is Hawaii?+
Hawaii spans zones 12a–12a, mostly zone 12. But frost dates, not zones, set planting time. The free planner uses your ZIP code's actual frost dates.
How many strawberries plants do I need?+
Depends who you're feeding. The crop page has exact counts per household size, or the free planner does the math for your family in about 60 seconds.
