Is it OK to plant marigolds with tomatoes?

Many gardeners believe in companion planting, the practice of placing certain plants in close proximity to each other to benefit both crops. One popular combination is tomatoes and marigolds. However, some growers have concerns about this pairing. So, is it OK to plant marigolds with tomatoes? Let's take a closer look.

The benefits of planting marigolds with tomatoes

Marigolds have several benefits when planted with tomatoes. One of the biggest advantages is pest control. Marigolds are a natural deterrent for a variety of garden pests, including nematodes, whiteflies, and aphids. By planting marigolds around your tomato plants, you can help keep these pests at bay.

Marigolds can also improve the soil quality around your tomato plants. They are known to repel harmful root-knot nematodes and other harmful organisms that can damage the roots of your tomato plants. Additionally, marigolds are a great source of nutrients, as they release compounds into the soil that can help improve soil health and promote plant growth.

Concerns about planting marigolds with tomatoes

Despite the numerous benefits of planting marigolds with tomatoes, there are some concerns to be aware of. The biggest concern is that marigolds may attract spider mites, which are a common pest in tomato plants. Spider mites feed on the sap of plants, which can cause yellowing and wilting of leaves, stunted growth, and a decrease in yield.

Another concern is that marigolds can sometimes negatively affect the flavor of nearby crops. While this is rare, some gardeners have reported that planting marigolds too close to tomatoes can result in a less-than-ideal taste.

How to safely plant marigolds with tomatoes

If you want to try planting marigolds with tomatoes, it's important to do so safely. Here are some tips to keep in mind:

Plant marigolds 2-3 feet away from your tomato plants to reduce the risk of spider mites.

Choose marigold varieties that are less likely to attract spider mites, such as French marigolds.

Plant marigolds in a separate bed or container from your tomato plants to prevent flavor contamination.

Rotate your crops every year to avoid pest and disease buildup in the soil. This will help keep your marigolds and tomatoes healthy and productive.

In conclusion

So, is it OK to plant marigolds with tomatoes? The answer is yes, as long as you take the necessary precautions to ensure the safety and health of both crops. By planting marigolds with your tomatoes, you can enjoy the many benefits of companion planting and create a thriving, productive garden.
