The Ultimate Guide to Companion Planting

Because plants have best friends too.

Companion planting is basically the garden version of choosing your roommates wisely. Some plants love each other. Some tolerate each other. And some… well, let’s just say tomatoes and fennel should never share a zip code.

Here’s your fun, friendly guide to pairing plants like a pro.

🌿 Why Companion Planting Works

Plants can help each other by:

• Repelling pests

• Improving flavor

• Boosting growth

• Providing shade or support

• Attracting pollinators

It’s teamwork — but with roots.

🍅 Classic Companion Planting Duos

Tomatoes + Basil

The power couple. Basil repels pests and makes tomatoes taste even better.

Carrots + Onions

Onions confuse carrot‑loving pests. Carrots pretend not to notice.

Corn + Beans + Squash (The Three Sisters)

Corn = support pole Beans = nitrogen fixer Squash = living mulch Together = unstoppable.

Cucumbers + Nasturtiums

Nasturtiums lure pests away like tiny floral decoys.

Roses + Garlic

Garlic keeps aphids away. Roses get to look fabulous.

🚫 Pairs to Avoid

Not all plants vibe.

• Tomatoes + Fennel — Fennel is the bad roommate who steals your sunlight.

• Potatoes + Tomatoes — Too many shared diseases. Drama.

• Beans + Onions — Beans hate onions. No one knows why.

🌻 Final Tip

Start small. Pair a few friendly plants together and watch the magic happen. Your garden will look happier — and so will you.
