How long does it take to grow a carrot?

Updated February 21, 2017

How long does it take to grow a carrot? That depends on a lot of factors, including type of carrot, condition of soil and, perhaps most importantly, when you decide to harvest it. Some people like the young, tender carrots, while others prefer to wait until the carrot gets big and bright orange. Carrots can be harvested anywhere from two months to four months after the seeds germinate.

The Basics

Carrots grow best in cool climates, even though they were originally grown and cultivated in the Mediterranean area. They are a root crop, just like potatoes and turnips, and are ideally planted in cooler temperatures, in the spring and again in the fall.

Carrots are by nature a biennial plant, completing their life cycle in two years. During the first year the carrot plant stores food in its root; in the second year it produces flowers and seeds. Most commercially cultivated carrots never make it past one year, however, because by then the root is fully grown--and that's what we eat.

Growing and Harvesting

Carrots are planted as seeds, and can take up to three weeks to germinate. If you're growing the common elongated orange variety, figure a good 12 weeks before the carrots are ready to harvest. The shorter, stubbier varieties may be reaped even earlier. It's best to read the back of the seed packet.

Some tips to make the carrots grow a little faster: Make sure your soil is loose and sandy to facilitate drainage and root growth; thin the seedlings after planting so they don't cannibalise each other in their quest for water and nutrients in the soil; keep the carrots free of weeds, especially when the carrot plants are young; and fertilise with common vegetable fertiliser, available at any garden store, when the carrot tops are about 4 inches high and, again, when they are about 6 to 8 inches high.

A Quick History

According to "What's Up, Doc," an article by Marion Owen on the, the first known cultivation of carrots took place in the seventh century, in Afghanistan. These early carrots were grown as a medicine and had purple skin and yellow flesh. It wasn't until the 1600s that Dutch horticulturists developed a stubby variation of the present-day orange carrot, which was subsequently improved by a French horticulturist who used a common wild flower, Queen Anne's Lace, to develop a long, thick carrot, bright orange in colour.

That's the same type of carrot that's still the most popular variety today, ubiquitous in supermarkets and farmer's markets all over the world.
