Lettuce is a popular crop for most market gardeners.
Direct seeding them is very difficult and often produces subpar results. Given that most market gardeners transplant their lettuce.
But transplanting lettuce (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 lettuce in a controlled environment then quickly and easily transplant it into the field 28 days later.
All without bending over and less transplant shock!

Suggested Tools for Paperpot Summer Crisp Lettuce
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.
- If the previous crop was fertilized, summer crisp lettuce will do fine without reapplication.
- If not, 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 Summer Crisp Lettuce in Paperpots
Seeding Lettuce 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 68°.
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 summer crisp lettuce.
There should be 7.5” between rows, and 3.75” from the outer rows to the edge of the bed.

Transplanting Summer Crisp Lettuce with the Paperpot Transplanter
Water the beds thoroughly with overhead irrigation or four rows of drip.
Frequent and consistent watering will promote succulent growth and avoid bitterness.
10-12 days after transplanting, cultivate using the Flex Tine Weeder (repeat again after 7 days).
A collinear hoe is also an effective cultivator for lettuce.
Harvesting Summer Crisp Lettuce
Summer Crisp Lettuce is ready for harvest when the heads are approximately 6” in diameter.
Harvest in the kneeling position next to the bed, two rows at at time. Harvest only the heads with dense hearts.
Remove slugs and damaged leaves if necessary.
Lettuce heads should be dunked in cold water when brought in from the field.
Do not soak for longer than one minute to avoid damage from becoming waterlogged.
Lay the lettuce heads on a drying screen to drip dry.
Stack the lettuce upside down in totes to continue draining in storage.
Store at 35° until taken to market.
