Cauliflower - Walcheren Winter

The densely packed heads are 10-15cm (4-6") in diameter on large plants and will withstand frost from -12 to -19°C (16 to -5°F) depending on wind and snow cover. Walcheren Winter does not start curd formation until after the winter frosts so expect to harvest in late winter to early spring.

Timing is critical: Aim to grow a plant about 15cm (6") tall by first fall frost. Start in May through June indoors and transplant by mid-August into well-drained soil in a spot protected from wind. Space plants at 60 x 75cm (24 x 30"). In spring when they start to leaf out, sprinkle a balanced organic fertilizer around the base of each plant and lightly work it into the soil. This overwintering cauliflower was a big hit in our trials.
