Full List of Nasturtium Companion Plants
These fruits, vegetables, flowers, and herbs all make excellent companion plants for nasturtiums. Many benefit from nasturtiums’ pest-deterring abilities (either in repelling the bugs or acting as a trap crop), the fact they attract pollinators, and/or their ground coverage.
Make sure you give the nasturtiums plenty of room if you sow them near other small to mid-size plants – they tend to grow large and spread into surrounding areas.
Fruits and Vegetables to Plant with Nasturtiums
• Apple Trees – If you have any apple trees, consider planting nasturtiums around the base. The nasturtiums act as a trap crop for a common apple pest called the codling moth.
• Beans – Similarly, nasturtiums act as an aphid trap crop for beans. The flowers also bring in beneficial pollinators for the bean plants.
• Beets and Carrots – Nasturtiums are an excellent trap crop/pest repellant to have near carrots and beets.
• Broccoli, Brussels Sprouts, Cabbage, Cauliflower, and Kale – With nasturtiums nearby, these brassicas family members are less likely to be bothered by Japanese beetles, aphids, and various cabbage-based pests.
• Celery – When planted nearby, nasturtiums are a great trap crop for celery.
• Corn – Aphids, Japanese beetles, and many other pests can decimate your corn crop, and a few sacrificial nasturtiums can make a big difference. And, since they’re small compared to the corn, you won’t have to worry about the nasturtiums taking over and blocking out light!
• Cucumbers, Melons, and Squash – Pumpkins, zucchini, and many other members of the melon, cucurbit, and squash family benefit from having nasturtiums nearby. Nasturtiums may improve the flavor of these fruits and vegetables while repelling many common pests. The large plants also benefit from cooler, damper soil thanks to the nasturtiums’ ground coverage.
• Eggplants, Peppers, Potatoes, and Tomatoes – Nasturtiums keep many pests away from these nightshades – like the dreaded Colorado potato beetle!
• Lettuce and Spinach – Leafy greens can have problems with aphids and other pests, so nasturtium trap crops work well nearby. (Here are some other great lettuce companions.)
• Radishes – Nasturtiums are a good trap crop for a variety of radish pests.
• Raspberries – Raspberries can be harmed by squash bugs and aphids, so planting nasturtiums nearby as a trap crop can improve your yield.
Flowers to Plant Near Nasturtiums
Just about any flower will get along with nasturtiums provided they don’t have to compete for growing space. Marigolds, snapdragons, hostas, salvia, daisies, petunias, and geraniums are just a few good options.
Herbs to Plant Near Nasturtiums

• Fennel – Like most plants, nasturtiums have trouble growing near fennel, as the herb stunts their growth.
