Growing Guide

Lamb’s lettuce should only be planted in cooler months (spring and fall), but it can tolerate temperatures as low as -20F (-28C) during winter. If there is a chance of freezing rain or blustering winds, you can grow them in a greenhouse.

Corn salad or lamb’s lettuce is best when it is cooler and the soil temperature is between 50-70F (10-20C).

These are some tips and steps to keep in mind:

  1. Place seeds lightly in a well prepared, fertile, and moist soil, about half an inch (1 cm) deep.
  2. Place seeds about 1 inch (2.5 cm) apart, with rows of 4 inches (10 cm) between. A thin layer of compost should be applied to the soil. Use moderate water.
  3. Germination should take place between 7-14 days.
  4. To help plants retain moisture and weeds, apply a thick mulch layer around them.
  5. Collect a few leaves from each plant to harvest lamb’s lettuce when needed (preferably before they flower). This counts as well a thinning process that allows for more leaves to be produced.
  6. The climate and soil conditions can affect how long it takes for lamb’s lettuce plants to stop growing.

You can harvest mature plants by taking the whole plant out of its roots and then cutting the stem off with a knife.

The leaves of lamb’s lettuce can be kept in the refrigerator for up to 4 days, but they taste best when fresh picked.


Regular watering is required for lamb’s lettuce.

Every plant needs 200 ml water approximately every two to three working days.

You can adjust the water intake for container-grown lettuces based on temperature and sun exposure.

Dry weather can not cause the plant’s death immediately, but it may cause its leaves to become softer or bitterer.

The last two weeks of harvest are the most critical time to water the plant.

Tip: Yellow, loose leaves indicate a water shortage. The plant will die if it is overwatered.

You can check the moisture level by touching the soil approximately 1 inch deep.

It should feel dry and sandy if it is.

Simple checks will help keep your lettuces healthy and fresh.


Lamb’s lettuce needs at least eight hours of sunshine per day. The remaining daylight hours should be in partial shade as they do not need direct sunlight.

This is especially important for extremely hot days.

Indoors, the plants of lamb’s lettuce require at least 12 to20 hours of sunlight.

Artificial lightning can be used to adjust the light requirements until at least the first seedlings appear.


The plants of lamb’s lettuce can thrive in any soil that is shallow, moist and well-drained.

To produce healthy plants, however, it is important to prepare the soil with fertilizers and manure.

Lamb’s lettuce is able to thrive in neutral soils, however acidic pH levels between 6.5 and 7.

Temperature and humidity

Lamb’s lettuce is an annual that can grow vigorously in mild climates. It’s also surprisingly resistant to extreme cold, provided it’s well-rooted.

The ideal temperature for growing lamb lettuce is between 13 and 18C (55-65F).

It is crucial to keep the lamb’s lettuce at a cool temperature in order to ensure that it grows well and produces tasty, healthy crops.

It can stress seedlings by making them too tall or too hot. This will cause them to grow taller and produce flowers and seeds that are not their time.

Pick the mature leaves. Thinning plants helps to reduce humidity, creates space for new growth and prevents the risk of fungus.

Potting and repotting

Lamb’s lettuce tastes best when it is sown in autumn. However, in warmer areas, it can be sown in the early spring.

You can move your container around until it is in the right place. These are the important steps you need to take:

  1. Place some nutrients-rich soil into a small container and dig a hole approximately 1 cm deep.
  2. If you don’t like the idea or rows, sow one seed in each hole.
  3. Add a thin layer to the soil and then press down with your hands. You can water moderately but keep the soil moist.
  4. When your first seedlings begin to appear, take them out carefully. Pay attention to the roots, as they can be fragile and delicate.
  5. Each seedling should be planted approximately 15 cm apart. To encourage new growth and prevent bolting, thin the old leaves. After producing at least four pairs of leaves, lamb’s lettuce can be harvested.
  6. You can leave a few plants to bloom and get seeds for new crops.

Pruning and Propagating

It is easy to propagate lamb’s lettuce. If you have the funds, you can easily propagate lamb’s leaves from leftovers.

  1. Place the lamb’s lettuce stem at 2 inches above the white part (without leaves) in a small jar.
  2. To be successful in the process, freshwater is vital. It should be changed every day.
  3. The jar should be placed in a sunny area or under grow lights. If the weather is warm, place it outside. Check the water level and temperature regularly.
  4. After a few days, new growth will begin to appear. If it doesn’t happen after seven days, it is likely that the experiment didn’t work out. Replant the seeds again.
  5. In 12 days, your new plant will be ready to harvest.

This method won’t yield the same quality and size of lettuces as when you grow it from seeds.

Although water doesn’t have the same nutrients that soil, it can be a great option for quick salads!
