 Sowing by climate zone 
Subtropic climate (Mediterranean) (e. g. B. Portugal, Spain, Italy)
Pre-cultivation is recommended from January to April or in autumn from September to November. The plants should ideally be planted in a sunny location.
Moderate climate (e. g. B. Germany, Switzerland, Poland)
Pre-cultivation from March to May or in late summer from August to September is recommended. The plants should ideally be planted in a sunny location.

 General recommendations 
Pre-cultivation and subsequent planting at the specified planting distance is recommended. For pre-cultivation, sow the seeds in a small bowl and let the seedlings grow until the first visible cabbage leaves appear, then transplant them into the desired container. 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.
White cabbage 'Wädenswiler' prefers a permeable, nutrient-rich, moist and humus-rich loamy soil. Doesn't tolerate waterlogging.

 Additional tips 
For a staggered harvest, several sowings at 8-week intervals are recommended. Avoid harvesting during frost in winter. To prevent cabbage flies from laying eggs, the use of vegetable protection nets is recommended. 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 
Loose, nutrient-rich and moist soil is essential. Depending on the condition of the soil, fertilization is recommended after 10 weeks.
