Growing lettuce in pots


You can start growing organic lettuce from an organic farmer in your area or from a nursery. Another option is to start from scratch by sowing the lettuce seeds.

To sow lettuce seeds follow these steps: Let the seeds soak in water 24 hours before. Sow the seeds in seedlings or seedbeds twice as deep as the thickness of the seed. Press the soil lightly and water carefully. Keep the soil of the seedbeds with a sufficient degree of humidity to favor the germination of the seeds.

The optimal germination temperature of lettuce seeds is around 17ºC. Try to keep the seedlings at this temperature and they will take between one and two weeks to germinate.


When the seedlings reach approximately 10 cm tall (more than 30 days may have passed since we sowed) we can transplant them. Take into account the space that each lettuce will need when it reaches its maximum size, just before harvest and try not to overcrowd the pots or planters. Try to leave a planting frame of at least 30 cm² for each lettuce.

Pots, grow tables, containers, planters … any container you use to plant lettuce must be at least 30 cm deep and in diameter.


Both for the seedlings or seedbeds and for the pots or containers in which you grow the lettuces, you can put a layer of sand at the base of the container (to promote water drainage) and then mix a part of worm humus with two of earth and fill the rest of the container with this mixture. Try to sift the mixture to avoid clods of earth that can hinder the development of the roots.


It depends on the variety, but in general they can adapt well to temperate and cold climates.

The optimum temperature is between a minimum of 5ºC and a maximum of 25ºC. Lettuces tend to withstand low temperatures better than high ones. On very hot days the lettuce tends to spike and is no longer suitable for consumption because it becomes more fibrous and the leaves have a bitter taste. The good thing is that we can obtain seeds for future plantings, see how to extract the seeds from lettuce .


Lettuce is not a very demanding plant in terms of sun exposure. It requires about 4 to 6 hours of light a day, but it can adapt to semi-shaded areas as well.


In the case of seedlings or seedbeds, I recommend that you water them by placing a tray or similar container under the container in which you can pour the water so that it is absorbed as needed. Later, when you have already transplanted the lettuce seedlings to their final cultivation place, we can continue using the same irrigation system, that is, put a tray or plate under the pot and pour the water there. In this way we avoid flooding and the plant absorbs little by little.

Lettuces are demanding with regard to watering and need to always have a certain amount of moisture in the soil. They do not cope well with the lack of water.


The most common pests that we can find during the cultivation of lettuce are aphids , snails and slugs , whiteflies and thrips.


In a period of 3 to 4 months (depending on the variety of lettuce and growing conditions) we can already harvest our wonderful organic lettuces. You can either harvest the whole lettuce, in one piece or harvest the leaves one by one when they are ripe and they will continue to sprout.
