1. Radishes
Radishes are fast-growing root vegetables that repel cucumber beetles, a common pest that damages cantaloupe vines. You can interplant them as a living barrier.
✅ Bonus: They mature quickly and won’t compete for resources.
2. Marigolds
These vibrant flowers are natural pest repellents, especially against nematodes, whiteflies, and aphids. Plant them along the borders of your melon patch.

Corn grows tall and can provide partial shade to your cantaloupes in extremely hot climates. It also acts as a natural trellis for lighter melon varieties.
⚠️ Note: Avoid letting cantaloupe vines climb too high or the weight may cause breakage.

Beans fix nitrogen in the soil, enriching it for hungry melon plants. Bush beans work well between rows, while pole beans can grow vertically nearby.
💡 Tip: Keep some space between beans and melons to reduce airflow issues.
6. Lettuce
Lettuce has shallow roots and grows quickly, making it ideal for planting between cantaloupe vines early in the season.

7. Oregano
This fragrant herb repels aphids and beetles with its strong scent. Oregano also attracts pollinators when it flowers.

Basil is another aromatic herb that can help deter pests. It pairs well with almost any garden plant and attracts pollinators too.
