Capitata ) is one of the most famous salads. Fortunately, the delicious lettuce can be grown in almost any climate and is also easy to care for. So that you can always harvest fresh lettuce, we will tell you everything you need to know about lettuce in this article: From its origin and different varieties, cultivation, care, and harvest to the use of lettuce.
Origin and properties of lettuce
The lettuce is one of the garden salads ( Lactuca sativa ). It belongs to the genus of the lettuce ( Lactuca ) and the sunflower family ( Asteraceae ). Unlike its siblings – iceberg lettuce ( Lactuca sativa var. Crispum) and Batavia lettuce (Lactuca sativa var. Capitata ) – it does not belong to the Crisphead group, but the Butterhead group. So, above all, its leaves are tender and not as crunchy as in other salads. This is why lettuce is sometimes called butter lettuce. In Austria, he is called “chief salad”. In Germany, lettuce ranks second behind iceberg lettuce with 20 percent of the cultivated area.
The lettuce probably originally came from the Middle East. It is said to come from the wild lettuce ( Lactuca serriola ), a steppe plant native to southern Europe and the Middle East. Lettuce is an herbaceous plant that forms a long taproot and rosette of leaves. The stem axis is strongly compressed in lettuce so that the leaves overlap around the stem and form a solid head. The leaves of the lettuce are very broad with a soft surface that is slightly oily to the touch. When it blooms, the lettuce shoots and forms an elongated stem on which numerous small, yellow flowers develop.
Popular types of lettuce

You can buy young plants in many garden centers, garden centers, and hardware stores. Specialized online retailers also offer pre-grown young plants for shipping.

The ideal location for lettuce
Lettuce loves it sunny. If he lacks light, his growth is restricted. Always plant it in full sun. The bottom of the salad should be loose and deep. As a medium eater, the lettuce is also happy about the high humus and nutrient content in the soil. The correct pH value is also important because the lettuce does not feel comfortable in soils that are too acidic. The pH value should therefore not be below 5.5.
The perfect location for lettuce at a glance:
- Full sun
- Deep, loose soil

Tip: Particularly good bed neighbors for a mixed culture with lettuce are strawberries ( Fragaria ), peas ( Pisum sativum ), beans ( Phaseolus vulgaris ), beetroot ( Beta vulgaris subsp. Vulgaris var. conditiva ), onions ( Allium cepa ), and spinach ( Spinacia oleracea ).
When do you grow lettuce?
You can start growing lettuce early in the year: from the end of February, it is time to give lettuce in a warm place. From the beginning of April, the tender lettuce can then also be sown directly in the garden bed. You can grow particularly late varieties until October. Earlier or purchased lettuce plants should best be planted out from the beginning of March.

You can prefer lettuce very well. To do this, sow the seeds in seed trays. The light germs are then only very lightly covered with earth and poured on. The lettuce germinates at temperatures between 15 and 18 ° C. If the temperatures rise above 20 ° C, the seeds can no longer germinate. As soon as the seeds have sprouted, you should separate them into individual pots. As soon as the young plants have four to five leaves and it is warm enough outside, the lettuce plants can move into the bed.

Caring for lettuce: water and fertilize properly
The first rule when caring for lettuce is: the soil must always be sufficiently moist. If the lettuce does not get enough water, the leaves become limp and droop. To avoid this, you should water regularly, especially in summer and on hot days.
If compost or a fertilizer with an organic long-term effect was worked into the soil during planting or sowing, your lettuce is optimally supplied with nutrients. Organic universal fertilizer releases its valuable ingredients slowly and gently to the lettuce, providing it with everything it needs to grow over the long term. Further fertilization is therefore not necessary.
