When to plant bell peppers: the short answer

Start seeds indoors about 8 weeks before your last spring frost; plant out about 2 weeks after it. Wait until the soil is at least 60°F; bell peppers sprout fastest near 82°F.

Zone 5: plant out May 7 – May 24. Zone 7: plant out Apr 12 – Apr 29. Zone 9: plant out Feb 27 – Mar 16. See every zone.

Bell Pepper is a warm-season vegetable in the Solanaceae family, usually started indoors and set out as transplants. It wants full sun (six or more hours of direct light) and steady, even moisture. From sowing to first pick is about 60–90 days. It is killed by frost, so nothing goes outside until the danger has passed and the soil has warmed.

Grower’s note: Needs warm soil; wait until nights stay above 55 F to transplant. Green peppers are just unripe coloured peppers left another 2-3 weeks.

Sowing

Sow about 0.25″ deep, into soil between 60–95°F — germination is quickest near 82°F. Germination takes a week or two (7–14 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 18″ along the row with roughly 30″ between rows. On a square-foot grid that is 1 per square foot. Allow at least 12″ of loose, workable soil for the roots. It grows well in containers at least 12″ deep.

Fitting it to your season

Bell Pepper needs roughly 60–90 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.

Questions gardeners ask

When should I plant bell peppers?

Start seeds indoors about 8 weeks before your last spring frost; plant out about 2 weeks after it. Wait until the soil is at least 60°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 do bell peppers take to grow?

About 60-90 days from transplanting to the first harvest, or roughly 19-23 weeks from sowing the seed indoors. Seeds germinate in 7-14 days.

How much sun do bell peppers need?

They need at least six to eight hours of direct sun a day.

What soil pH do bell peppers need?

A soil pH between 5.5 and 7.0. 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 bell peppers?

Space plants about 18 inches apart in rows 30 inches apart, or 1 per square foot in a square-foot bed. Sow seeds about ¼ inch deep.

Can I grow bell peppers 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.
