Description
Romaine lettuce 'Forellenschluss' is an old, historic and annual leaf vegetable from the 19th century in Austria. This decorative and little-known variety is only cultivated by a few seed breeders. This popular romaine lettuce with a crisp midrib forms large, open heads with elongated, egg-shaped, green and red-speckled leaves. The stable, tender and crisp structure of the leaves tastes sweet, similar to iceberg lettuce. A very pretty specialty for growing in the cooler seasons. Very bolt-resistant selection with a long harvest window. For spring and autumn cultivation.

Sowing by climate zone
Subtropic climate (Mediterranean) (e. g. B. Portugal, Spain, Italy)
Pre-cultivation in small bowls from January to April or in autumn from September to December is recommended. The plants are ideally placed in partial shade.
Moderate climate (e. g. B. Germany, Switzerland, Poland)
Pre-cultivation in small bowls from February to July is recommended. The plants should ideally be placed in a sunny location.
General recommendations
Pre-cultivation is recommended for large heads of lettuce. When pre-cultivating, sow the seeds in a small bowl and let the seedlings grow until the first visible lettuce leaves appear, then transplant them into the desired containers. After transplanting, let the seedlings grow at moderate temperatures until they are planted out as seedlings. Plant the seedlings in the bed from the second pair of leaves after the cotyledons.
Romaine lettuce 'Forellenschluss' ideally prefers a soil that is moist, permeable, nutrient-rich and contains plenty of humus and loam. It does not tolerate waterlogging.
Additional tips
For a staggered harvest, several sowings at intervals of 4 weeks are recommended. For a long harvest period, harvest 1/4 of the leaves from the outside to the inside and take care not to damage the heart in order to keep growth stable. In order to quickly obtain a fine, crumbly and permeable soil with good nutrient and water storage capacity, additional incorporation of biochar and primary rock flour is recommended.
Type of propagation
Propagation occurs via seeds.
Plant care
Loosened, nutrient-rich soil and mixed planting are sufficient for lettuce. No fertilization necessary.
