Tomato plants can get hurt by pests like aphids, spider mites, and whiteflies. These pests can harm the plant and ruin the crop. Whiteflies are especially bad for tomatoes because they drink the sap from the leaves and stems.

This makes the leaves turn yellow and fall off. It's hard to keep pests away without using strong chemicals. But Alan Titchmarsh made a video showing how to use companion planting to keep pests away from tomatoes naturally.

Companion planting means growing different plants together to help each other.

The goal is to make plants healthier, have fewer pest problems, attract helpful insects, and get more produce without using chemicals.

Tomatoes should not be grown near potatoes, broccoli, or corn, but there's one plant Alan recommends.

French marigolds are good to grow with tomatoes.

In his video, Alan said marigolds are good for attracting bees and other pollinators. They are also good when planted with tomatoes because they help keep pests away.

French marigolds have a strong smell that helps tomatoes when they are grown together.

You can grow marigolds and tomatoes in the same bag, pot, or soil.

Alan said the strong roots of marigolds help keep whiteflies away from tomatoes.

The roots of marigolds mix with the roots of tomatoes and help keep whiteflies away.

French marigolds also add color to the garden in the summer.

Basil is another plant that grows well with tomatoes.

Basil attracts pollinators and makes good use of garden space.
