When to plant ginger: the short answer
Start seeds indoors about 8 weeks before your last spring frost; plant out about 3 weeks after it. Wait until the soil is at least 70°F; ginger sprout fastest near 80°F.
Zone 5: plant out May 14 – May 31. Zone 7: plant out Apr 19 – May 6. Zone 9: plant out Mar 6 – Mar 23. See every zone.
Ginger is a warm-season vegetable in the Zingiberaceae family, usually started indoors and set out as transplants. It wants partial shade — four to six hours of sun is enough and consistent moisture — it resents drying out. From sowing to first pick is about 240–300 days. It is killed by frost, so nothing goes outside until the danger has passed and the soil has warmed.
Grower’s note: Start with plump "seed ginger" rhizome pieces that show visible growth eyes/buds - fresh nursery stock sprouts far more reliably than old, dried grocery-store roots. Needs 8-10 months of real warmth to bulk up, so in most of the US it lives in a large container that spends summer outdoors and comes in well before the first frost. Harvest a little tender "baby ginger" any time after a few months, or dig the whole clump once the leaves yellow in fall.
Sowing
Sow about 2″ deep, into soil between 70–90°F — germination is quickest near 80°F. It is slow and often erratic to germinate (14–42 days). For an early crop, start seed indoors about 8 weeks before your last spring frost and grow it under bright light.
Spacing & layout
Give each plant about 8″ along the row with roughly 18″ between rows. On a square-foot grid that is 1 per square foot. Allow at least 8″ of loose, workable soil for the roots. It grows well in containers at least 12″ deep.
Fitting it to your season
Ginger needs roughly 240–300 frost-free days to crop. Where the season is shorter than that, start it indoors and choose the earliest-maturing varieties, or grow it in a container you can move under cover on cold nights. In long, hot-summer regions it can often be planted twice — once in spring and again in mid-to-late summer for a fall harvest.
Quick facts
Growth stages: how long ginger takes to grow
From seed to first harvest takes roughly 45-54 weeks: about 11 weeks as a seedling indoors, then 240-300 days in the garden.

Questions gardeners ask
When should I plant ginger?
Start seeds indoors about 8 weeks before your last spring frost; plant out about 3 weeks after it. Wait until the soil is at least 70°F. The table on this page gives dates for each USDA zone, and the planting calendar gives dates for your own state or ZIP code.
How long does ginger take to grow?
About 240-300 days from transplanting to the first harvest, or roughly 45-54 weeks from sowing the seed indoors. Seeds germinate in 14-42 days.
How much sun does ginger need?
It needs about three to four hours of sun, ideally with shade in the afternoon.
What soil pH does ginger need?
A soil pH between 5.5 and 6.5. It tolerates fairly acidic soil better than most vegetables. Test before adding lime or sulfur - see the soil pH and testing guide.
How far apart should I plant ginger?
Space plants about 8 inches apart in rows 18 inches apart, or 1 per square foot in a square-foot bed. Sow seeds about 2 inches deep.
Can I grow ginger in a container?
Yes. Use a container at least 12 inches deep with drainage holes and a good potting mix, and water more often than you would in the ground.
