How to Grow Cabbage In Paperpots (Paper Chain Pots)
Growing Cabbage in Paperpots
No hand transplanting!
Less transplant shock!
Growing cabbage in paper chain pots will increase your chances of having a successful crop!
Cabbage is a popular crop for most market gardeners.
Direct seeding is very difficult and often produces subpar results. Because of this most market gardeners transplant their cabbage.
But transplanting cabbage (the traditional way) brings its own set of problems. Transplanting is both time and labor-intensive.
The Paperpot Transplanter solves this problem.
It allows you to germinate cabbage in a controlled environment then quickly and easily transplant it into the field 28 days later. All without bending over or transplant shock!
12″ in-row spacing for early cabbage can be accomplished by seeding every other cell in a 6″ paper chain pot. Paperpot Co. makes custom Skip Plates for the Kwik Klik™ (KK) Drop Seeder to make seeding every other cell as quick and efficient as possible!

Suggested Tools for Paperpot Cabbage
Bed Preparation for Paperpot Transplanting
- Broadfork the bed to aerate and loosen the soil.
- Smooth and shape the bed with a bed preparation rake, removing any debris.
- Cabbage will do best in beds freshly amended with fertilizer.
- Here are two options:
- 1) Layer on 1” of compost, enough to mostly cover the native soil.
- 2) Sprinkle on a combination of alfalfa meal and pelleted chicken manure.
- If layering compost, do not tilth in hopes of smothering any surface weed seed.
- If adding amendments, tilth the top 1-2” of soil to mix in amendments.
- Irrigate for 10-14 days*, allowing any weed seed in top layer of soil to germinate.
- Flame weed the bed when the cotyledons of the weed seeds have emerged.
Growing Cabbage in Paperpots
Seeding Cabbage in Paperpots
Prepare trays with 6” paper chain pots, and fill with potting mix.
Install Paperpot bottom plate and custom “skip” top plate into Kwik Klik™ (KK) Drop Seeder.
Note: the pattern on the skip plate will only allow a seed to drop in every other cell of the 6″ paper chain, creating 12” in-row spacing.
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 72 hours at 86°.
Transfer the trays to greenhouse tables after germination.
Transplanting Cabbage with the Paperpot Transplanter
Water the beds thoroughly with overhead irrigation, or four rows of drip.
To prevent cabbage moths, immediately cover the beds with floating row cover (or insect netting in the warm season). The cover will only come off for cultivation and harvest times. Weigh down the edges with sand bags every 5 feet.
It is important to water throughout hot days during the warm season.
14-16 days after transplanting, cultivate using a collinear hoe.
After this point the heads should fill out to form a canopy and shade out any potential weeds.
The Flex Tine Weeder is also an effective cultivator for cabbage when it is young.
Cabbage will benefit from a side dressing of nitrogen rich fertilizer half way through its maturity.
For highest yield, cut the cabbage heads when they are solid (firm to hand pressure).
Use a freshly sharpened knife for harvesting cabbage.
Remove large peripheral leaves so just the head remains.
Cabbage heads do not require being washed after harvest.
Cabbage should be taken quickly to the cooler after coming off the field.
Store at 35° until taken to market.
Washing and Packing Cabbage
Overall Paper Chain Pots make cabbage a much more farmer-friendly crop.
Time savings, ease of transplanting, and high germination rates are some of the reasons why cabbage is a popular market garden crop grown in paperpots.
