What is a Good Companion Plant for Tomatoes?

Tomatoes are a popular crop in many home gardens. They are easy to grow, delicious, and packed with nutrients. But did you know that planting specific companion plants alongside your tomatoes can benefit both the tomatoes and the other plants? Companion planting is a gardening technique where different species of plants are grown together to enhance their growth and health.

Benefits of Companion Planting with Tomatoes

Companion planting with tomatoes can provide a range of benefits. Some plants can deter pests and diseases that commonly affect tomatoes. Others can help to improve soil health by fixing nitrogen or providing additional organic matter. Additionally, some companion plants can enhance tomato flavour and yield, while others may simply make for a visually appealing garden.

1. Basil - This herb has been shown to enhance tomato flavour and aroma, and its strong scent can repel certain pests such as aphids and tomato hornworms.

2. Marigolds - These colourful flowers have a strong odour that can deter nematodes, whiteflies, and other tomato pests. Some studies also suggest that marigolds may improve tomato growth and yield.

3. Borage - This herb attracts pollinators like bees and can also repel tomato hornworms and other pests. Additionally, borage leaves and flowers are edible and can add an interesting flavour to salads and other dishes.

4. Nasturtiums - These beautiful flowers have a pungent odour that can repel pests like aphids and whiteflies. They also make a colourful addition to any garden and their leaves and flowers are edible and can add a peppery taste to salads.

While there are many plants that can benefit tomatoes, there are also some that should be avoided. Certain plants can attract pests or diseases that can impact tomato growth and yield. Plants in the nightshade family, such as peppers and eggplants, should be avoided as they can attract the same pests and diseases that affect tomatoes.
