Want a happy, healthy veggie garden? 🧑🌾
Then it’s time to get your plants some good neighbors! Just like people, vegetables have friends they grow better with — and a few they’d rather avoid.
This guide will help you pair onions, lettuce, cucumbers, and peppers with the best plant buddies. Plus, we’ll share some easy garden planning tips to help your garden thrive!
What is companion planting?
Companion planting means growing certain plants next to each other to help them grow better. Some companions scare away bugs, improve soil, or give helpful shade. It’s nature’s way of teamwork!
Best companion plants for onions
- Carrots, Lettuce, Spinach: These veggies enjoy onion’s strong scent — it helps keep bugs away.
- Peppers: Onions and peppers are happy to share sun and space.
Avoid: Don’t plant beans next to onions — they don’t get along and can harm each other’s growth.
Who grows best with lettuce?

Lettuce loves soft soil and shade. Good companions include:
- Chives, Carrots, Onions, Arugula: They’re light feeders and won’t take up too many nutrients.
- Spinach: Needs similar water and sunlight, so they’re great roommates.
Avoid: Don’t plant celery too close to lettuce. It grows aggressively and can take over the space.
Cucumber’s favorite companions
Cucumbers enjoy company that helps them stay balanced and bug-free:
- Dill, Beans, Peas, Onions: These help with pest control and soil health.
- Marigolds and Calendula: Keep bugs away and make the garden look pretty.
Avoid: Potatoes can pass fungal diseases to cucumbers — keep them apart.
What pairs well with peppers?
Peppers like sunny, warm conditions and appreciate gentle protection. Great companions are:
- Carrots, Basil, Chives, Onions, Spinach: Together they form a natural shield.
- Marigolds: Help prevent aphids and beetles from attacking peppers.
Plant Combos to Avoid

Here are the plant pairs that just don’t work well together:
- Onions and Beans: These plants compete and don’t grow well side-by-side.
- Cucumbers and Potatoes: High risk of spreading disease between them.
- Lettuce and Celery: Celery can take over and crowd out the lettuce.
