Conseils de culture
Frost exposure converts starches to sugars, making fall and winter-harvested kale noticeably sweeter than summer crops.
Harvest outer leaves first, leaving the growing point intact to allow continuous production over many weeks.
Kale is an excellent overwinter crop in mild climates; mulch the base and it will resume growth in early spring.
