Growing onions in Zone 6 during July requires careful planning to ensure a healthy and productive harvest. Companion planting can enhance growth, deter pests, and improve soil health. Here are some of the best companion plants for July-grown onions in Zone 6.
Benefits of Companion Planting with Onions
Companion plants can help:
- Repel pests such as aphids and carrot flies
- Improve soil fertility
- Enhance flavor and growth

Top Companion Plants for July-Grown Onions
Carrots
Carrots and onions are mutually beneficial. Onions repel carrot flies, while carrots help loosen the soil around onion roots, promoting better growth.
Beets
Beets grow well alongside onions, sharing similar soil and watering needs. They also help suppress weeds.
Celery
Celery benefits from onions’ pest-repelling properties and can thrive in the same soil conditions.
Spinach
Spinach and onions grow well together, with spinach providing ground cover that helps retain soil moisture during hot July days.
Plants to Avoid Near Onions
Some plants may compete with onions or attract pests. Avoid planting:
- Potatoes, which can spread disease
- Beans, which may compete for nutrients
- Fennel, which can inhibit onion growth
Additional Tips for July Onion Planting
Ensure your onions have adequate water during hot July weather. Mulching can help retain soil moisture and suppress weeds. Rotate crops annually to prevent disease buildup.
Using companion planting strategies can lead to a healthier, more productive onion crop in Zone 6. Happy gardening!
