Nasturtiums are known for their pest-repelling properties, which can protect cauliflower from common pests like aphids and cabbage worms. Both plants thrive in similar conditions, although there are some differences in their growth requirements that gardeners should consider. Cauliflower prefers cooler temperatures and consistent moisture, while nasturtiums are more tolerant of dry conditions. Despite these differences, their compatibility in terms of pest control and overall garden health makes them excellent companions.
