You can grow purple carrots by planting their seeds in loose, well-drained soil that gets plenty of sunlight.
Unlike the orange carrots you see in most grocery stores, purple carrots have a deep, almost regal color and a slightly sweeter, earthier flavor.
If you’ve ever wondered how to grow purple carrots in your own backyard, the good news is that they’re just as easy to grow as the regular orange kind.
In fact, purple carrots are one of the oldest varieties of carrots, originally grown in regions like Central Asia and the Middle East.
In this post, we’ll walk through how to grow purple carrots step by step, from choosing the right seeds to harvesting those vibrant roots.
Let’s dig in.
How to Grow Purple Carrots: The Basics
Growing purple carrots starts with understanding what they need to thrive.
These root vegetables are cool-season crops, which means they grow best in spring and fall.
Here’s what you need to know to get started.
1. Choose the Right Purple Carrot Variety
Before you learn how to grow purple carrots, pick a variety that suits your climate and taste.
Popular options include ‘Purple Haze,’ ‘Cosmic Purple,’ and ‘Dragon’ carrots.
Each offers a slightly different shade and flavor, so don’t be afraid to experiment.
2. Pick the Perfect Spot
Purple carrots need full sun, ideally six to eight hours a day.
They also need loose, sandy soil that drains well.
If your soil is heavy clay, mix in some compost or sand to help the roots grow straight and long.
3. Plant at the Right Time
The best time to plant purple carrot seeds is two to three weeks before the last frost in spring, or about ten weeks before the first frost in fall.
Soil temperature should be at least 45°F for the seeds to germinate.
Planting and Caring for Purple Carrots
Now that you know the basics, here’s how to plant and care for purple carrots so they grow healthy and strong.
1. Sow the Seeds Directly
Purple carrot seeds should be sown directly into the garden, since transplanting can damage their delicate roots.
Plant the seeds about a quarter-inch deep, spacing them one to two inches apart.
Keep the soil consistently moist until the seedlings emerge, which usually takes one to three weeks.
2. Thin the Seedlings
Once your purple carrots sprout, thin them so they’re two to three inches apart.
This gives each root enough room to develop without competition.
If you skip thinning, you’ll end up with small, twisted carrots instead of nice, straight ones.
3. Water and Weed Regularly
Purple carrots need about an inch of water per week.
Water deeply and less often to encourage strong root growth.
Keep the area weed-free, since weeds steal nutrients and moisture from your carrots.
4. Watch for Pests and Diseases
Common pests like carrot flies and aphids can bother purple carrots, just like orange ones.
Row covers can help protect your crop, and rotating where you plant each year reduces the risk of disease.
Harvesting and Enjoying Purple Carrots
Knowing when and how to harvest purple carrots is key to getting the best flavor and texture.
1. When to Harvest
Most purple carrot varieties are ready to harvest 65 to 80 days after planting.
You’ll know they’re ready when the tops of the roots push through the soil and reach about three-quarters of an inch across.
2. How to Harvest
Loosen the soil around each carrot with a garden fork before pulling.
Grab the greens near the base and pull gently.
If the soil is too dry or compacted, the carrot might snap, so water the day before harvesting to make things easier.
3. Storing Your Purple Carrots
After harvesting purple carrots, cut off the greens and store the roots in a cool, humid place.
A refrigerator crisper drawer works well, or you can keep them in a box of damp sand in a root cellar.
They’ll stay fresh for several weeks if stored properly.
4. Cooking with Purple Carrots
Purple carrots can be eaten raw, roasted, steamed, or juiced.
Their color may bleed when cooked, so consider roasting them separately if you’re mixing with other veggies.
They add a beautiful pop of color to salads and side dishes.
So, How to Grow Purple Carrots?
You can grow purple carrots by planting their seeds in loose, well-drained soil with plenty of sunlight.
From choosing the right variety to watering, weeding, and harvesting at the right time, the process is simple and rewarding.
