Introduction

Marigolds are known to play an important role in tomato gardening. Not only do they add vibrant colors to your garden, but they also have the potential to repel harmful nematodes and other pests. To reap the most benefits, choosing the right type of marigold to plant with your tomatoes is crucial. In this article, we will explore the different types of marigolds to plant with tomatoes.

French Marigolds

French marigolds are a popular choice for companion planting with tomatoes. These compact plants produce an abundance of small flowers all summer long. They are also known to deter pests such as whiteflies and spider mites. French marigolds come in a variety of colors, including yellow, orange, and red.

African Marigolds

African marigolds are larger than French marigolds and produce bigger flowers. They are also known to have a stronger scent, which may help repel pests such as nematodes. African marigolds come in a range of colors, from yellow to orange and red. They are great for adding height and drama to your garden.

Signet Marigolds

Signet marigolds are smaller than French and African marigolds but are equally effective in repelling pests. They produce attractive clusters of small, edible flowers that have a citrus-like taste. Signet marigolds are available in shades of yellow and orange and are perfect for adding a pop of color to your garden.

Which Marigolds to Avoid

While marigolds are generally beneficial for tomato gardening, not all types of marigolds are suitable. Avoid planting Mexican marigolds (also known as Aztec marigolds), which can release chemicals that are toxic to tomato plants. Additionally, avoid planting Marigold ‘Lemon Gem’, a hybrid variety that has been found to attract whiteflies.

Conclusion

In conclusion, choosing the right type of marigold to plant with your tomatoes can help enhance their growth and protect them from harmful pests. French marigolds, African marigolds, and signet marigolds are all excellent options to consider. Just remember to avoid planting Mexican marigolds and ‘Lemon Gem’ marigolds. By selecting the right marigolds, you can enjoy a bountiful and healthy tomato harvest.
