Bed preparation

Broadfork the bed to loosen the soil. Loose soil means straight, shapely carrots.
Smooth and shape the bed with a bed prep rake, removing any debris.
Layer on 1″ of compost or sprinkle on alfalfa meal and/or pelleted chicken manure. Don’t tilth in compost; tilth amendments into the top 1-2″.
Irrigate for 10 to 14 days* to germinate weed seed. Row cover speeds this up. Flame weed once the weed cotyledons are up.

Seeding

Set up the Jang: X24 roller, 14 x 10 sprockets (front x rear), brush down.
JP1: seed 6 evenly spaced rows across the bed.
JP5: fill only hoppers 1, 3 and 5, then seed the bed in two passes for 6 evenly spaced rows.
6 to 7 days after seeding, before the carrots emerge, flame weed again to catch late weeds.

Bed layout

Irrigation

Keep the top layer of soil from drying out until the carrots germinate (10-14 days).
Deep watering supports early growth. Too much water late in the crop can crack the roots.

Cultivation

When the tops are 3-4″ tall (20-25 days* after seeding), cultivate between rows with a collinear hoe, flex tine weeder or wheel hoe with bio-disc cultivator. The bio-disc hills the rows as it goes.
Pull larger weeds by hand. After that the canopy closes and late weeds aren’t a threat.

Harvest

Harvest at 5-7″ for the best tenderness and flavor.
Selling by the bunch: bunch 8-10 carrots right after pulling and stack them in a tote.
Selling by the pound: twist off the tops in the field.

Washing and packing

Spray each bunch with a washdown gun over a root wash table, turning it until all the soil is off.
For loose carrots, spray them in a perforated harvest tote, sliding it around so every side gets clean.
Store carrots at 35°F in a plastic bag or tote to keep them moist and crisp until market.

*All timing varies with your climate, soil and season.

Questions

Carrots with the Jang: FAQ

What Jang roller do I use for carrots?

X24, with the 14-tooth sprocket in front and the 10-tooth in the rear, brush down. That gives about 1″ between seeds. Test the roller at the bench with your seed lot before you go to the bed.

How much seed do I need?

About 20 g for a 100′ x 30″ bed at 6 rows. Round up when you order.

How long until harvest?

About 55 days (36 for baby) from seeding, with a harvest window of about 20 days. Timing varies with your climate, soil and season.
