About

More Than a Root Vegetable

Carrots are the domesticated form of wild Queen Anne's lace, bred over centuries from purple and yellow roots into the familiar orange we know today — though heirloom varieties still come in deep purple, red, white, and golden shades. They belong to the same family as parsley, fennel, and dill, and their feathery tops are just as telling as the roots below.

What carrots lack in drama above ground they more than make up for below it. Sugars concentrate as roots mature, and a light frost actually sweetens them further by converting starches to sugar — making a late fall harvest one of the garden's quiet pleasures.

How to grow

Planting & care

Sow seeds directly into the garden 2-3 weeks before the last frost date, or in late summer for a fall crop. Loose, deep, stone-free soil is non-negotiable: compacted or rocky ground produces forked, stubby roots. Raised beds and deep containers work beautifully. Sow thinly, about 1/4 in deep, and keep the seedbed consistently moist until germination, which can take 14-21 days.

Thin seedlings to 2-3 in apart once they reach 2 in tall — crowding is the number-one cause of small, misshapen carrots. Side-dress with a low-nitrogen fertilizer at planting; too much nitrogen pushes leafy tops at the expense of roots. Water deeply and evenly to discourage forking. Mulch between rows to retain moisture and keep the soil cool.

Good to know

Green Shoulders Mean Cover Up

When carrot shoulders push above the soil surface and are exposed to sunlight, they turn green and develop a bitter flavor. Simply mound a little soil or mulch over the tops as they grow to keep them covered and tasting sweet all the way through.
