Frequently asked questions
What zone does carrot grow in?
Carrot is grown fresh each year, so it fits every zone. What changes is when you plant. Find your zone by ZIP code.
How much sun does carrot need?
Full sun. Full sun means at least six hours of direct sun a day; part shade means about three to six.
Hardiness ranges, light and size are typical figures from university extension services and botanic garden plant records; a named variety can differ, so check its tag. Planting dates come from each zone's median frost dates (NOAA 1991 to 2020 climate normals) and the timing rules in how we check.
