As soon as the soil is frost-free and no longer too wet, can be started with planting in the field.
Light soils allow planting as early as the end of March. On heavy soils it will rarely be feasible before early to mid-April.
Who has the qualifications, grow the plants yourself, must be sown in a warm box by the end of February at the latest. Earlier outdoor lettuce is given stand widths of 25 cm x 20 cm to 25 cm x 25 cm. Later plantings and summer varieties are given larger planting distances of 30cm x 25cm to 30cm x 30cm. Plant protection hoods are recommended for the early planting dates. They not only promote growth, but also protect against bird damage.
