Companion planting for common vegetables

What you’ll practice

Build confidence choosing compatible neighbors for common vegetables, herbs, and flowers based on pest pressure, nutrient needs, and growth habits.

You’ll also sharpen your ability to spot “looks-helpful” pairings that actually compete for light, water, or root space.

Quiz format and difficulty

Each question has 4 options and there’s no timer, so you can think through the garden logic instead of rushing.

Pick your preferred question count and difficulty before you start—Mixed blends easy wins with tougher scenario-style items to keep the challenge balanced.

Common pitfalls to avoid

- Assuming all herbs are universally beneficial companions - Ignoring plant size and shading as the season progresses - Mixing heavy feeders together without planning extra fertility - Confusing pest-repellent folklore with reliable pairings - Forgetting spacing and airflow when interplanting n ## Tips for better scores

Focus on why a pairing works (pest deterrence, trap cropping, pollinator support, or resource sharing) rather than memorizing lists. When two plants have similar water and light needs and different root depths, they’re often safer companions.
