How to Grow Kohlrabi In Paperpots (Paper Chain Pots)

Growing Kohlrabi in Paperpots

Better germination!

No hand transplanting!

Less transplant shock!

Kohlrabi is a perfect crop to grow in paper chain pots. Starting the seeds in the nursery, versus the field, gives you great germination rates; and the kohlrabi seedlings transplant easily with the Paperpot Transplanter.

Kohlrabi is a crop that most market gardeners wouldn’t think of as a paperpot crop, but it’s one that works really well in the Paperpot system. 

The Paperpot Transplanter can transplant seedlings quickly and easily into the field 28 days after starting the seeds.

All without bending over and less transplant shock!

The kohlrabi heads will size up perfectly – the paper chain doesn’t affect formation.

Seeding Kohlrabi in Paperpots

Prepare trays with 6” paper chain pots, and fill with potting mix. 

Install Paperpot bottom plate and specified top plate into Kwik Klik™ (KK) Drop Seeder

Pour seed onto the top plate and rotate until one seed fills each hole. 

Position the KK Drop Seeder over the tray, ensuring the holes are lined up with the cells, and click to drop the seeds. 

Water the trays, then place in germination chamber for 48 hours at 77°. 

Transfer the trays to greenhouse tables after germination. 

Thoroughly water trays before heading to the field for transplanting.

Using the Paperpot Transplanter, plant the four rows of kohlrabi.

There should be 6” between rows with 3” from the outer rows to the edge of the bed.

Transplanting Kohlrabi with the Paperpot Transplanter


Water the beds thoroughly with overhead irrigation or four rows of drip.

Frequent shallow waterings will support rapid growth.

10-14 days after transplanting, cultivate using a Terrateck Wheel Hoe with the bio-disc cultivator attachment.

A weekly pass with the flex tine weeder is also an effective tool for preventing weeds.

Cultivation (Weeding)

Harvesting Kohlrabi

Kohlrabi is ready for harvest when the bulbs are 2.5 to 3.5”.

Kohlrabi is harvested while straddling the 30” bed and cutting at the base with a harvest knife or pruning shears.

Create bunches of 3-4 bulbs in the field, rubber banding the greens.

Using a Washdown Gun sprayer over a root wash table, spray each bunch while rotating until all soil is thoroughly cleaned off.

Transfer the washed bunches to totes, and store at 35° until taken to market.

Washing and Packing Kohlrabi
