Romaine Lettuce: Main Characteristics

Romaine lettuce, known for its elongated shape and crisp leaves, is a widely prized variety of lettuce. Below, its main characteristics, historical background, sowing time to harvest, soil, climate, temperature, most recommended sowing method, sowing depth, germination, cultivation, irrigation and harvest are detailed.

Historical background

Romaine lettuce, also called "cos" in some places, is a variety of lettuce that has been grown for centuries. It has its origins in the Mediterranean region and has been a staple food in many cultures throughout history.

Sowing Time to Harvest

The time required from planting to harvest of romaine lettuce varies depending on local conditions and the specific variety. Romaine lettuces can typically be harvested 70 to 85 days after planting when grown under optimal conditions.


Romaine lettuce thrives in well-drained soil rich in organic matter. The ideal soil pH for growing lettuce is in the range of 6.0 to 7.0. The soil should be loose and well-drained to avoid root rot problems.

Climate and Temperature

Romaine lettuce is a cool weather vegetable and prefers moderate temperatures. The optimal temperature for its growth is in the range of 15-20°C (59-68°F). Avoid extreme heat, as it can cause lettuce to become bitter and prone to premature flowering.

Most Recommended Sowing Method and Sowing Depth

Direct sowing into the ground is the most common method of growing romaine lettuce. The planting depth should be approximately 0.5 cm. Maintain adequate distance between seeds to allow optimal growth and space needed for head development.


Romaine lettuce seeds generally germinate under adequate moisture and temperature conditions within 7 to 10 days. Provide constant watering during this period to facilitate uniform germination.

Cultivation and Irrigation

Keep the soil consistently moist while growing romaine lettuce. Water regularly and prevent the soil from drying out completely. Using mulch can help conserve moisture and reduce weeds.



Romaine lettuce is harvested when the heads are well formed and compact. The entire plant can be cut at ground level or, if preferred, individual leaves can be cut as they mature. Harvesting should be done before the plant blooms to maintain optimal flavor and avoid bitterness.

Romaine lettuce is a versatile and tasty variety of lettuce that, with proper care, can be a highlight in your garden or vegetable garden.
