Benefits of Companion Planting with Tomatoes
Companion planting offers several advantages for tomato plants, including:
- Repelling pests such as aphids and whiteflies
- Attracting beneficial insects like pollinators and predatory bugs
- Improving soil health through nitrogen fixation
- Providing shade and wind protection
- Enhancing flavor and growth
Top Companion Plants for September Tomatoes
Basil
Basil is a classic tomato companion known for improving the flavor of tomatoes. It also helps repel pests like mosquitoes, flies, and aphids. Plant basil nearby to create a fragrant barrier that benefits both plants.
Marigolds
Marigolds are excellent for pest control, especially against nematodes and aphids. Their bright flowers attract beneficial insects and serve as a natural deterrent to harmful pests.
Garlic and Onions
Plant garlic or onions near your tomatoes to repel spider mites, aphids, and other pests. Their strong scent acts as a natural pest barrier, making them valuable companions.
Carrots
Carrots help loosen the soil around tomato plants and are a good companion because they do not compete for the same nutrients. They also attract beneficial insects that prey on tomato pests.
Leafy Greens
Plants like lettuce, spinach, or kale can be grown alongside tomatoes to provide ground cover, retain soil moisture, and suppress weeds. They also attract pollinators that benefit tomato growth.
Plants to Avoid Growing Near Tomatoes
While many plants support tomato growth, some can hinder it. Avoid planting:
- Potatoes
- Cabbage
- Fennel
- Broccoli
- Cauliflower
These plants can attract pests or compete for nutrients, which may reduce your tomato harvest.
Conclusion
Choosing the right companion plants can significantly improve your September tomato crop. Incorporate herbs like basil, flowers like marigolds, and vegetables like garlic to create a healthy, pest-resistant garden. Happy planting!
