Companion planting is one of those timeless gardening secrets that make your vegetable patch more productive and resilient. By pairing crops that help each other grow, you can naturally repel pests, improve pollination, and make better use of space. Here are ten easy companion planting layout ideas featuring cucumbers, peppers, squash, and more.
1. Cucumber & Dill Patch
Plant cucumbers alongside dill to attract beneficial insects like predatory wasps and bees. The dill helps improve cucumber flavor while supporting pollination.
2. Pepper & Basil Duo
Basil protects peppers from aphids and whiteflies, and its strong scent can enhance fruit flavor. Space them about 12 inches apart for good airflow.
3. Three Sisters Garden
A classic Indigenous design—corn for height, beans to climb, and squash as ground cover. The result is a self-supporting ecosystem that conserves moisture and suppresses weeds.
4. Cucumber & Corn Border
Let corn serve as a natural trellis for cucumbers. This vertical combination saves space and keeps cucumbers dry and disease-free.
5. Pepper & Marigold Bed
Ring pepper plants with marigolds. Their scent deters nematodes and beetles while adding cheerful color.
6. Squash & Nasturtium Mix
Nasturtiums act as a trap crop, attracting aphids away from your tender squash leaves. Plus, they bring edible beauty to the garden.
7. Cucumber, Lettuce & Radish Row
Start with quick-growing radishes and lettuce between slower cucumber vines. You’ll harvest early while cucumbers spread later.
8. Pepper & Onion Strip
The strong aroma of onions confuses pests that target peppers. Try alternating rows for the best effect.
9. Squash, Beans & Borage
Borage draws in pollinators and improves the flavor of nearby vegetables while helping deter tomato hornworms and other pests.
10. Border of Herbs
Surround your veggie beds with rosemary, thyme, and oregano. These herbs discourage pests while attracting beneficial insects that keep your cucumbers, peppers, and squash thriving all season long.
