Winter rosette salad, 4 g of farmers' seeds, sow from August to October

Verte de Cambrai corn salad, in organic, open-pollinated seeds from the Kokopelli association, is a winter salad that fills the vegetable patch from October to March, when everything else is resting. The 4 g packet is sown in place from August to October, at 0.5 cm deep, in rows 25 cm apart. Cut at the base, the rosette regrows for a second cut.

La Verte de Cambrai is an heirloom lamb's lettuce, already grown in France in the early 19th century and close to the Coquille de Louviers, which forms small rosettes of tender, green, rounded leaves. It fills the place that no other salad takes, that of winter, from October to March, when the rest of the vegetable garden is dormant. Sow it in late summer, it settles in slowly with the cool nights, and its great hardiness lets you cut it all winter.

❄️ A late-summer seedling

Sow in place, from August to October, at a depth of 0.5 cm. For rows, sow thinly in furrows spaced 25 cm apart, firm lightly, then keep the soil moist until emergence, which takes 10 to 20 days. If your bed is in full sun at the end of summer, shade the rows for a week, because above 20 °C corn salad seed germinates poorly. You can also sow 5 to 7 seeds per pot or per soil block, then transplant these clumps every 10 cm, in rows spaced 20 to 30 cm apart, which gives even rows without thinning.

Sow

Sow in place from August to October, at 0.5 cm deep, in rows 25 cm apart.

Weight down

Firm the seedbed with the back of a rake: seed germinates better in contact with damp soil.

Harvest

Cut the rosette at the crown: it grows back and gives a second cut.

A seed drill for sowing thinly in a furrow

Lamb's lettuce seed is small, and a 4 g packet holds far more than a single row needs: poured by hand, it falls in clumps that then have to be thinned. A hand seeder lets you place it evenly in the drill, as a thin sowing requires. The same tool then serves for the other fine seeds in the seed section, in spring.

✂️ The winter harvest

Lamb's lettuce is harvested from October to March, as you need it. Cut the rosette with a knife, at the crown, rather than pulling it up: the plant then regrows from the centre and gives a second cut later in the winter. Wait for the daytime thaw before harvesting, because a leaf caught in ice breaks and blackens on the cut edge. The variety is very hardy in the cold, and a fleece laid over the bed before the hard frosts mainly protects the harvest, keeping the leaves supple under the knife.

For clean lamb's lettuce, mulch lightly between your rows in autumn. Splashes of soil lodge in the heart of the rosettes and make washing a long job, whereas mulching greatly limits them. La Verte de Cambrai thrives in partial shade as well as in full shade, which also allows you to plant it at the foot of a hedge or behind a tall late-summer crop, on a bed that would otherwise stay empty all winter.

💧 Lamb's lettuce in aquaponics

Its needs are low: a short, fibrous root system, little nitrogen, no structure to support. It therefore settles in easily on your raft or in a grow bed filled with clay pebbles. The limit is the water temperature: below 10 °C, the activity of the filter's bacteria slows sharply, and it is then the system that limits the crop, not the plant. Indoors or in an unheated greenhouse, you have here one of the few useful winter crops, as set out in the guide to autumn seedlings in aquaponics.

Frequently asked questions

6 questions

6 key questions

When should you sow lamb's lettuce to harvest in midwinter?

Sow between mid-August and the end of September, the window that gives the largest rosettes.
Draw rows spaced 25 cm apart and sow thinly along the row.
Firm the seedlings in with the back of a rake, then water with a fine spray.
Keep the soil moist until germination, which takes between 10 and 20 days.

An October sowing will still germinate, but its rosettes stay small and are mostly harvested at the end of winter.

Why won't my lamb's lettuce germinate in the middle of August?

What spacing and depth should I use when sowing lamb's lettuce?

Can lamb's lettuce be transplanted?

What you need to know

Firm the seedbed down with the back of a rake or with a board. Lamb's lettuce germinates poorly in a fluffy soil, because the seed needs firm contact with damp earth to sprout.
If you sow in August, sow in the evening on soil watered the day before. Above 20 °C, the seed germinates poorly, then comes up late and unevenly.
Sow in blocks of 5 to 7 seeds if you want regular rows. The clumps are transplanted whole every 10 cm, without thinning.
Cut the rosette at the crown rather than pulling it up. It regrows from the heart and gives a second cut later in the winter.
Mulch lightly between the rows in autumn. Splashed soil makes washing lamb's lettuce tedious, and a mulch greatly reduces it.
In aquaponics, the limit is not the lamb's lettuce but the water temperature. Below 10 °C, the bacteria in the filter slow down and the available nitrogen decreases, whereas indoors the crop carries on normally.
