Companion planting is a proven method in gardening where certain plants are grown together to improve growth, repel pests and increase productivity. This process helps create a harmonious garden and reduces the need for chemical fertilizers and pesticides. Here are 20 plant pairs that thrive when grown together:
- Tomatoes and Basil
Basil is an ideal companion for tomatoes because it enhances the flavor and deters pests like aphids and whiteflies. Additionally, the strong smell of basil can repel mosquitoes, making your garden more enjoyable.
- Carrots and onions

Honey acts as a natural deterrent to carrot flies, while carrots help aerate the soil, creating a mutually beneficial relationship.
- Corn and beans .
This classic pair is often referred to as “Three Sisters” when combined with pumps. Beans enrich the soil by fixing nitrogen, which benefits corn, while corn provides a natural trellis for beans.
- Cucumber and nuts
Nasturtiums are an excellent companion for cucumbers because they attract pollinators and repel insects such as cucumber beetles, which act as a natural insect control system.
- Lettuce and Red
Radishes grow quickly and can be harvested early, allowing space for lettuce to mature. Together they make good use of the garden space and help suppress weeds.
- Vegetable dishes .

Velvet is a versatile companion to most vegetables. Its vibrant flowers repel insects and other insects, promoting healthy growth for nearby plants.
