  Nasturtiums

  

  Instead of insecticides, consider planting species that attract other animals to take care of your garden’s pests. The nasturtium’s bright orange flowers are one of the best flowers for vegetable gardens and will attract insects like wasps that eat the kinds of pests like aphids, whiteflies, and spider mites drawn to celery, Jones says.

  Perhaps it’s no surprise, but pests don’t necessarily enjoy the smell of onions either. “Onions deter carrot flies in particular,” Jones says.

  Though carrot flies are drawn to carrots more than other plants, celery will still benefit from the onions because they are slow growing, allowing the celery to get first pick on where it plants roots.

  Marigolds

  Cucumber

  

  While many plants with a strong odor, like garlic and chives, benefit celery on this list, celery also has its own strong smell. The celery scent can discourage whiteflies, which love the flavor of cucumbers, so they benefit one another. Meanwhile, cucumbers grow tall, offering celery shade to combat too much sun exposure.

  Sage

  

  Another plant with a strong smell, sage repels carrot flies and cabbage moths. Especially during warmer months, tall herb plants like sage can help filter sunlight to protect and cool down celery plants.

  This garden plant attracts the attention of ladybugs, a major connoisseur of aphids, which will protect young celery plants as they're growing.
