Growing tomatoes can be a rewarding experience, but it’s crucial to be mindful of their neighbors in the garden. Some plants can hinder their growth, attract pests, or spread diseases. Here’s a guide to seven plants to avoid planting near your tomatoes, along with the reasons why, to help ensure your tomatoes thrive.
1. Black Walnut
Why to Avoid: Black walnut trees produce juglone, a toxic chemical found in their roots, leaves, and nut hulls.
Impact: Juglone can cause wilting, stunted growth, and even death in tomato plants.
2. Corn
Why to Avoid: Corn shares common pests with tomatoes, particularly the corn earworm, also known as the tomato fruitworm.
Impact: Planting these crops close together can lead to increased pest pressure, damaging both plants.
3. Kohlrabi
Why to Avoid: Kohlrabi aggressively competes for soil nutrients, which can stunt tomato growth.
Impact: Both plants may suffer from undernourishment, leading to poor yields.
4. Potatoes
Why to Avoid: As members of the nightshade family, potatoes and tomatoes are susceptible to the same blight.
Impact: Disease can quickly transfer between the two, risking the loss of both crops.
5. Fennel
Why to Avoid: Fennel secretes substances from its roots that inhibit the growth of tomatoes and other plants.
Impact: Tomatoes planted near fennel may exhibit reduced vigor and lower fruit production.
6. Cabbage
Why to Avoid: Cabbage and its relatives (broccoli, cauliflower) attract similar pests as tomatoes, such as aphids and flea beetles.
Impact: The presence of these pests can worsen damage to tomatoes.
7. Dill
Why to Avoid: While young dill can be beneficial, mature dill secretes compounds that are harmful to tomatoes.
Impact: Older dill plants can stunt tomato growth, negatively affecting their health.
General Tips for Planting Near Tomatoes
- Companion Planting: Consider planting basil, marigolds, or garlic near tomatoes. These plants can help repel pests and enhance tomato growth.
- Spatial Arrangement: Ensure adequate spacing between tomato plants and potentially harmful neighbors to minimize competition and disease transmission.
- Monitoring and Maintenance: Regularly check your tomato plants for signs of stress or disease, and practice crop rotation to maintain healthy soil.
