Brussels Sprouts is a perennial grown for the harvest, ready about 100 days after sowing. It's hardy across USDA zones 2 through 11. Its flowers are a moderate draw for honeybees and native bees, even though the harvest is the prize. As a brassica (the cabbage family), give it a fresh bed each year — away from where its relatives just grew — so the soil-borne pests and diseases of the family never get a foothold.

What Brussels Sprouts is
Brussels Sprouts grows as a perennial and reaches around three feet at maturity.
How to grow Brussels Sprouts
Brussels Sprouts grows in USDA zones 2 through 11 and is ready to harvest about 100 days after planting. Brussels Sprouts does best in part sun — at least 4 hours of direct sun a day — and soil from pH 5.5 to 8.5, on well-drained ground. It needs around 2,000 growing degree days to mature and a growing season of at least 60 frost-free days, which is why climate matters as much as soil.

Start the season right
Plant brussels sprouts in part sun with at least 4 hours of direct sun, once the soil has warmed and frost risk has passed.
Match the soil
Brussels Sprouts prefers pH 5.5 to 8.5 (USDA PLANTS Database). A quick soil test from your local Extension lab tells you whether to add lime or sulfur to land in band.
Water steadily
Keep the root zone evenly moist through establishment. A 2–3 inch mulch layer holds moisture without waterlogging.
Harvest at maturity
Brussels Sprouts is ready about 100 days after sowing (UMass-Veg; Cornell). Watch for cultivar-specific ripeness cues and pick at peak.

Where Brussels Sprouts thrives
On hardiness alone, brussels sprouts grows across most of the country — its range (USDA zones 2 through 11) is unusually wide. Zone is only the starting point, though: the soil pH, drainage, and frost dates on your specific land decide how well it actually does.

Frequently Asked Questions
Can I grow Brussels Sprouts in my zone?

How long does Brussels Sprouts take to grow?
Brussels Sprouts is ready to harvest about 100 days after planting (UMass-Veg; Cornell). Your local frost dates and soil temperature move that window earlier or later.
When should you plant Brussels Sprouts?
Most growers plant brussels sprouts after the last spring frost, once the soil has warmed, leaving enough of the season for its 60-day frost-free need. Your local frost dates set the exact window — a Growable Ground report reads them for your address.
How much sun does Brussels Sprouts need?
Brussels Sprouts does well in partial sun — around 4 hours of direct sun, and it takes some afternoon shade in stride. That flexibility makes it a good match for a bed the house or a nearby tree shades for part of the day. A Growable Ground report maps how the sun actually falls on your land, hour by hour, so you can set it where the light lines up.
What soil does Brussels Sprouts need?
Brussels Sprouts prefers soil pH 5.5 to 8.5, on well-drained ground (USDA PLANTS Database). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Brussels Sprouts attract pollinators?
Yes — brussels sprouts's flowers are a solid nectar source for honeybees and native bees (Xerces Society, Pollinator Partnership).
Is Brussels Sprouts safe for pets?
Brussels Sprouts is not known to be toxic to dogs or cats based on available data (ASPCA). Always supervise pets around new plantings.
