How Many Marigolds Per Tomato Plant

Marigolds and tomato plants are some important components of most gardens. Besides providing a beautiful sight, both can assist in pest control and disease prevention. As such, many gardeners wonder if there is an ideal ratio of marigolds to tomato plants. Read on to find the answer.

Companion Planting

Companion planting is the practice of growing different plants together, so they benefit each other. Tomato plants and marigolds are some of the most popular companion plants because of their pest-repelling properties. Marigolds contain limonene, which is toxic to harmful insects like whiteflies and nematodes. On the other hand, tomato plants contain solanine, which makes them resistant to some pests and diseases.

The Ideal Ratio

The ideal ratio of marigolds to tomato plants varies depending on the size of your garden and the purpose of companion planting. Generally, it is recommended to plant one marigold per every three to four tomato plants. This means that for a garden with six tomato plants, you should plant two marigolds. This ratio ensures that the marigolds provide enough pest control while not being too overwhelming for the tomato plants.

Planting Tips

To get the best results from companion planting tomato plants and marigolds, consider the following planting tips:

Place the marigolds in-between the tomato plants or plant a few around the tomato plants' perimeter

Ensure the marigolds are mature or grown from seeds, so they are of similar heights or grow taller for optimal coverage and shade. This will, in turn, discourage weeds from growing

Water both plants regularly to prevent the soil from drying and provide essential nutrients for both plants' growth and development

Prune off the lower leaves of the tomato plants to allow more airflow, which increases sunlight penetration for optimal growth

Use organic fertilizers or soil amendments to maintain the soil's fertility and increase their resistance to diseases and pests

Conclusion

In conclusion, planting marigolds with tomato plants is beneficial for your garden. The ideal ratio of marigolds to tomato plants is one marigold per every three to four tomato plants to ensure effective pest control. By following the planting tips provided, you can achieve optimal growth and yield from both marigolds and tomato plants. Before you start, always remember to research the best marigold and tomato plant varieties for your garden and climatic conditions. Happy gardening!
