    Sowing lettuce for seedlings

    How to grow lettuce indoors and outdoors at home

    You can plant salad for seedlings at any time of the year, from January to May. In the spring, the container is placed on a lighted window sill, and in winter it is necessary to provide additional lighting with phytolamps. For cultivation, a substrate is taken, which contains coconut fibers and vermicompost.

    Planting lettuce is done in several stages:

    1. A drainage layer is laid out in the container.
    2. The box is filled with moistened soil.
    3. The seeds are planted to a depth of 1 cm.
    4. The pot is covered with glass or foil, and then removed to a dark place.

    When the first seedlings appear, you can remove the cover and put the box in a bright place.

    When to sow salad for seedlings

    To figure out when to plant lettuce outdoors, many turn to the lunar calendar, according to which favorable days for planting in 2021:

    Choosing varieties of lettuce for home growing

    For a home garden, watercress and lettuce varieties are best. The head varieties are practically not adapted to the conditions of insufficient illumination. 

    Nothing good will grow out of them on the windowsill. As for the varieties, we choose the earliest, shade-tolerant and drought-tolerant ones. Among leafy lettuce salads for growing at home, varieties are best suited: Batavia; Lolo Rossa; Lolo Bionda; Grand Rapids; Vitamin; Red Creed; Emerald lace; New Year. 

    And watercress will do any kind. It grows as well as green onions and can even do without soil. We will return to the technology of obtaining watercress greens later, it deserves special attention.

    Growing lettuce from seeds

    High-quality seed preparation for planting will help to achieve a rich harvest. First of all, you need to choose the right seed. It is worth checking the expiration date and tightness of the package.

    Growing lettuce leaves begins with seed treatment:

    1. The seed should be sorted out and the damaged seeds should be thrown away.
    2. Then the seeds must be placed in a saline solution. Hollow instances will pop up. They need to be thrown away.
    3. For disinfection, the seed is placed in a weak solution of manganese for 30 minutes.
    4. After that, the seeds must be soaked in a growth stimulant solution.

    After completing all these activities, we plant the seed in pre-prepared soil.

    How to grow lettuce indoors and outdoors at home

    The first steps

    Growing lettuce indoors is easy with basic care. Choosing the right crockery, soil and seed preparation is the path to success in home gardening.

    Choosing a container for growing

    The plant has small roots, so shallow containers up to 10-15 cm high are just right for it. It is best to choose plastic bowls, containers, clay or ceramic containers. You also need to follow the conditions:

    1. containers for cultivation must have holes so that excess water flows into them during watering, so a pallet is required;
    2. on the bottom of the selected container, the first layer must be laid out drainage(expanded clay, pebbles, small pebbles);
    3. when using an old pot, it must be washed with soap or a weak solution of potassium permanganate. This is done to prevfeatures
    4. remaining bacteria and pest eggs from the previous plant from settling on the root system.

    You can refuse containers and containers by planting lettuce seeds in the ground in a plastic bag, cutting it to the desired height and making perforations.

    What soil is suitable

    For salad it is best to choose “Universal” or “Vegetable” substrate purchased in a specialized store. Do not sow material in saline and saline soil with an acidic reaction, as well as use heavy and clayey soil. The presence of humus will give a positive result in cultivation.

    You can prepare the substrate yourself. To do this, take and mix thoroughly:

    1. Sand, peat and humus in a ratio of 1: 1: 2.
    2. Biohumus and coconut fiber, garden soil (1: 2: 1).
    3. Peat mixed with complex fertilizer.

    The land taken from its own garden plot, before mixing with other components, is subject to preliminary disinfection with a weak solution of potassium permanganate.

    What type of soil to use for growing lettuce?

        If you store lettuce leaves in containers all year long, you will need a well-draining potting mix that provides the right amount of nutrients, such as the Miracle-Gro Potting Mix.

        If you are going to plant lettuce in your garden, you need to add nutritious garden potting soil to the ground.such as Miracle-Gro Expand N Gro

    Seed preparation

    Self-harvested seeds require preliminary preparation. To do this, immerse them in a light pink solution of potassium permanganate and leave for 1 hour for etching (disinfection).

    Granular seeds from the store do not need pre-sowing preparation. When buying, you need to pay attention to their expiration date and the integrity of the packaging.

    How to plant correctly

    Growing lettuce at home can be done all year round. Sowing is done in stages:

    • drainage is placed on the bottom of the container;
    • fill up the soil;
    • place lettuce seeds in moist soil and sprinkle with a handful of soil 0.5-1 cm;
    • gently watered so as not to wash out the seed. It is better to do this with a spray bottle. Cover with foil and place in a dark place with a temperature of 20-22 ° C;
    • when the first shoots appear (3-4 days), the polyethylene is removed, and the crops are transferred to a well-lit space with a temperature of 16-20 ° C. Higher temperatures will cause flower arrows to appear prematurely.

    You can eat salad when 5-10 full-fledged sheets are formed.

    What to provide conditions for growth

    The correct development of a culture depends on caring for it. Agrotechnical methods for growing lettuce leaves on a windowsill include four main factors: light, temperature, moisture and watering. Important techniques are feeding and thinning, if necessary.


    Lettuce needs 10-12 hours of light for healthy growth. In winter, you will have to organize additional lighting using a fluorescent lamp or phytolamp to extend the access of light by 3 hours. Such manipulations will accelerate the development of seedlings. However, they need protection from direct sunlight.

    For uniform illumination, it is recommended to turn the container with lettuce seedlings 1-2 times a week by 180 degrees.


    The salad belongs to cold-resistant plants. The most favorable temperature regime is + 16 ... + 20 degrees. For greenery, an elevated temperature is considered more dangerous than cool and dry air. It promotes the formation of flower arrows and gives the leaves a bitter taste.


    The salad needs regular moisture during the growing season. Moisture is especially important in hot weather. If the leaves are drooping, they do not have enough water. They become coarse and lose their beneficial properties. At the same time, waterlogging of the soil should not be allowed, this can lead to plant disease.

    Lettuce seedling care

    Lettuce seedling care: watering thinning feeding,

     supplementary lighting With the appearance of green shoots, we remove the polyethylene from the containers and put them on a light windowsill. 

    The south, southeast or southwest sides are, of course, preferable, but in fact we put where there is a place. Now the main care of the seedlings will be regular watering and backlighting. Salads do not like dry soil and dry air, so they will have to be watered often (every other day or two). 

    At low air humidity in the room, it is necessary to spray the leaves from time to time. Young seedlings can be sprayed more often at first than watered at the root. 

    The frequency and amount of watering depends on the weather, the location of the containers and the temperature at the window. 

    It is clear that lettuce growing on the southern windowsill will need more moisture. And on sunny days, water evaporates faster, etc. For irrigation and “shower” from the sprayer, we use settled tap water at room temperature. 

    The optimal light day for a salad is 12-14 hours. This means that in the fall and winter from 2 to 5 hours we need to compensate with additional lighting. We place the fluorescent lamps at a height of 60 centimeters above the drawers.


    Thin the salad twice. The first time - after 7 days from the appearance of the first shoots. We pull out the extra seedlings so that there are 1-2 centimeters between the neighbors.

     The second time (with the appearance of two or three true leaves) we leave a distance of 4-5 centimeters between the plants. The thickening in the boxes is harmful: it provokes the stems to stretch, and little greenery is formed at the same time. 

    By the way, the removed plants can be planted in separate cups and grown to a full-fledged outlet. It is necessary to feed salad crops only if we are not sure about the fertility of the soil. 

    Have you brought the land from the nearest clubs? Then we will feed it once with Humate or a universal fertilizer for indoor plants. Have you sown lettuce in purchased soil or added vermicompost to the box? There is no need to feed additionally.

    Moisten the soil before planting. For growing lettuce, the planting scheme is important - you need to sow not a lot. The seeds are evenly spread over the surface, and then sprinkled with a centimeter layer of soil.

    Let's talk about how lettuce leaves are grown, depending on the phase of development. Sprouts appear on days 7-14. From that moment on, they must be watered every day, preventing the soil from drying out, and the young leaves must be moistened from a spray bottle. It is important not to allow the seedlings to bloom, then the crop can be harvested for 4 months.

    How to grow homemade salad

    When growing lettuce indoors, it is important to follow the basic planting and grooming conditions. The plant has small roots, so shallow containers are suitable for planting. The container must have holes for water to drain. Drainage is laid out at the bottom of the container.

    A store-bought substrate for vegetables is suitable for growing lettuce. The advantage will be the presence of humus in the composition. You can also make the mixture yourself. Here are some recipes:

    1. Peat, humus and sand in proportions 1: 2: 1.
    2. Vermicompost, ordinary earth and coconut fiber in proportions 1: 1: 2.
    3. Peat mixed with fertilizers.

    Watering the salad

    If lettuce grows on a windowsill, it should be watered every 2-3 days. Do not allow the soil to dry out, as this leads to the formation of flower arrows and the appearance of a bitter taste in the greenery. If the humidity in the room is low, additional humidification with a sprayer is required.

    Salad dressing

    For active growth, the plant needs to be fed. Liquid fertilizer is applied to the soil once a week. Mullein solution is suitable as a top dressing. The culture consumes nitrogen and other nutrients from the finished soil mixture. Ash infusion is used to strengthen the root system.
