Cauliflower, a member of the brassica family, benefits from the pest-repelling properties of thyme and alyssum. Thyme is a hardy herb that requires similar growing conditions to cauliflower, while alyssum acts as a beneficial ground cover that attracts pollinators and deters pests like aphids.

Key Factors:

• Growth Requirements: Cauliflower and thyme thrive in similar sunlight and soil conditions, while alyssum’s adaptability makes it a great companion.
• Pest Control: Thyme’s aromatic oils deter cabbage moths, a common pest of cauliflower. Alyssum attracts beneficial insects like hoverflies that prey on aphids.
• Nutrient Needs and Spacing: These plants have compatible nutrient requirements and can be spaced efficiently to maximize garden space.
