Suggested Tools for Paperpot Mesclun Mix 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, mesclun mix 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 Mesclun Mix 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 mesclun mix.

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

Transplanting Mesclun Mix Lettuce with the Paperpot Transplanter


Irrigation


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.

Cultivation (Weeding)


Harvesting Mesclun Mix Lettuce


Mesclun mix is ready for harvest when the heads are approximately 6” in diameter.

Harvest just above the growing tip (about 1’’ from the soil) with a sharpened harvest knife.

The leaves should be about 2-4” (+/-). If the lettuce leaves are too big, cut higher on the plant.

Cut away any leftover leaves after your initial cut, making sure the core is clean for regrowth and the next harvest. (Take note to remove insects, rotten leaves, or debris while in the field.)

Agitate the lettuce by hand (or use a bubbler) for no more than 4 minutes in the wash tube, while scanning for debris, bugs, or damaged greens.

Adding a sanitizer like Sanidate 5.0 sanitizer to the water will kill any possible pathogens, and will also help improve the shelf life of the mesclun.

After drying and bagging (usually in 1/2lb or 1lb bags), store the greens at 35°.

Attempt to sell mesclun mix within 3 days of harvest for highest quality.
