You can pick purple carrots when the roots reach about ½ to ¾ inch in diameter at the top, usually 60 to 80 days after sowing.
That’s the sweet spot for most purple carrot varieties, though the exact timing depends on what you plan to do with them.
Knowing when to pick purple carrots is honestly half the battle with these colorful root veggies because they can go from perfect to pithy faster than you’d expect.
If you’re new to growing purple carrots, don’t worry.
This guide walks you through the right time to harvest purple carrots, the signs to look for, and how to keep them tasting great after you pick them.
Let’s dig in.
When to Pick Purple Carrots
When to pick purple carrots comes down to a few reliable signals, and here they are:
1. Check the Days to Maturity on Your Seed Packet
Most purple carrot varieties mature in about 65 to 80 days, so that’s your first benchmark for when to pick purple carrots.
Start checking the soil around the 60-day mark if you’re impatient like me, but don’t pull anything yet.
Just gently brush back the soil at the top of the root to peek at the shoulder size.
That little sneak peek tells you more about when to harvest purple carrots than the calendar ever will.
2. Look for the Shoulder Size
The top of the carrot, called the shoulder, is the best indicator of when to pick purple carrots.
You want it to be around ½ to ¾ inch across for a tender, sweet carrot.
If the shoulder looks tiny, give it another week or two before picking purple carrots.
Bigger isn’t always better, by the way.
Overgrown purple carrots turn woody and lose that lovely sweetness, so don’t wait too long when deciding the right time to pick purple carrots.
3. Watch the Color Deepen
Purple carrots get their color from anthocyanins, and that rich purple hue deepens as they mature.
When the top of the root shows a deep, saturated purple poking through the soil, it’s usually a sign that the time to pick purple carrots has arrived.
Faded or pale shoulders mean the carrot is still developing, so hold off.
Signs Your Purple Carrots Are Ready to Harvest
Beyond the calendar, here are the visual and physical signs that tell you when to pick purple carrots:
1. The Tops Look Full and Healthy
Lush, green, feathery foliage about 10 to 12 inches tall is a good sign your purple carrots are nearing harvest time.
When the leaves start to droop or yellow, that’s your cue to pick purple carrots right away before they decline further.
2. The Roots Push Up Through the Soil
When the crown of the carrot breaks the soil surface and shows its color, you’re close to the ideal time to pick purple carrots.
This usually happens in the final couple of weeks before full maturity.
3. A Gentle Test Pull
If you’re still unsure about when to pick purple carrots, sacrifice one carrot as a test.
Loosen the soil around it with a fork, pull it up, and check the size and texture.
If it’s tender and sweet, the rest of your crop is ready for picking purple carrots too.
How to Pick Purple Carrots the Right Way
Once you know when to pick purple carrots, the actual harvesting matters just as much:
1. Water the Soil First
Water your bed the day before you plan to pick purple carrots.
Moist soil makes the roots easier to lift without snapping them.
2. Loosen Before You Pull
Never yank straight up when picking purple carrots.
Slide a garden fork beside the row and gently lift the soil first.
Then grip the carrot at the crown and pull with a steady, even motion.
3. Harvest in Cooler Hours
Pick purple carrots in the morning or late evening when temperatures are mild.
Carrots harvested in the heat of the day lose moisture faster after picking.
So, When to Pick Purple Carrots?
You should pick purple carrots when the roots reach ½ to ¾ inch in diameter at the shoulder, usually 60 to 80 days after planting.
Watch for deep color, healthy tops, and shoulders pushing through the soil, and you’ll never second-guess the timing again.
The best part about knowing when to pick purple carrots is that you can harvest them young for snacking or let them size up for roasting.
Either way, fresh purple carrots from your own garden beat anything from the store, so get out there and start checking your crop.
