Description
Horseradish is a hardy perennial with a strong taproot that releases sharp mustard oils when grated. It spreads aggressively through root fragments, so it is best kept in a defined area.
Care instructions
Plant root cuttings (called "fechser" or side shoots) at an angle in deep, loose soil in spring and give the plant plenty of space. Harvest the roots after the first frost in October when they are most pungent. When digging, leave some root pieces in the ground if you wish to maintain the stock; otherwise dig thoroughly, as each root piece will sprout anew.

carrot family (Apiaceae)
You can pair celery and dill with all Brassicaceae because they repel the cabbage whitefly with their scent, a proven companion.

mint family (Lamiaceae)
You will notice that the intense scent of basil, thyme, and others confuses the cabbage whitefly and keeps it away from the cabbage family.

nasturtium family (Tropaeolaceae)
Nasturtium serves as a trap plant for you. Aphids and cabbage whiteflies prefer it over the brassicaceae next to it.
For example Tropaeolum majusMashua
