The year in Berlin
What can move the date
A long-season crop that must be planted firm — loose soil gives open, blown sprouts. Stake tall varieties before autumn gales, and never over-feed with nitrogen late.
Final spacing: 60 × 75 cm. Soil: pH 6.5–7.5.
Direct-sow only once the soil holds 7°C or more — soil temperature decides germination, not the date.
