Tomatoes And Onions: The Perfect Companion Planting

Tomatoes and Onions: The Perfect Companion Planting

Tomatoes and onions are two of the most popular vegetables grown in home gardens. They are also two of the best companion plants for each other. Companion planting is the practice of planting certain plants together to benefit each other. When tomatoes and onions are planted together, they can help to improve each other's growth and productivity.

How Tomatoes and Onions Benefit Each Other

There are several ways that tomatoes and onions benefit each other. One way is by deterring pests. The strong odor of onions can help to repel pests such as aphids, tomato hornworms, and whiteflies. Tomatoes, on the other hand, can help to repel nematodes, which are microscopic worms that can damage plant roots.

In addition to deterring pests, tomatoes and onions can also help to improve each other's soil health. Onions release sulfur into the soil, which can help to improve drainage and reduce the risk of diseases. Tomatoes, on the other hand, are heavy feeders and can help to add nitrogen to the soil.

Finally, tomatoes and onions can also help to improve each other's pollination. The flowers of both plants attract pollinators such as bees and butterflies. This can help to ensure that both plants set fruit.

Which Tomatoes and Onions to Plant Together

When choosing tomatoes and onions to plant together, it is important to consider the mature size of both plants. Tomatoes can grow quite tall, so it is important to choose a variety that will not outgrow the space you have available. Onions, on the other hand, are relatively short-lived and do not need as much space.

Some good tomato varieties to plant with onions include:

• Bush tomatoes: These varieties grow to be relatively short and compact, making them ideal for small gardens. Some good bush tomato varieties include 'Celebrity', 'Better Boy', and 'Early Girl'.
• Cherry tomatoes: These small, sweet tomatoes are perfect for snacking or adding to salads. Some good cherry tomato varieties include 'Sungold', 'Sweet 100', and 'Beefsteak'.

Some good onion varieties to plant with tomatoes include:

• White onions: These onions are mild and sweet, making them a good choice for salads and sandwiches. Some good white onion varieties include 'Yellow Granex', 'Walla Walla Sweet', and 'Copra'.
• Yellow onions: These onions are more pungent than white onions, making them a good choice for cooking. Some good yellow onion varieties include 'Spanish White', 'Yellow Globe', and 'Jersey Wakefield'.

How to Plant Tomatoes and Onions Together

To plant tomatoes and onions together, start by preparing the soil. The soil should be well-drained and fertile. If the soil is not fertile, you may need to add compost or other organic matter.

Once the soil is prepared, plant the tomatoes and onions according to their respective spacing requirements. Tomatoes should be spaced about 2 feet apart, while onions should be spaced about 6 inches apart.

Water the tomatoes and onions well after planting. Continue to water them regularly, especially during dry weather.

When to Harvest Tomatoes and Onions

To harvest tomatoes, simply cut the tomatoes from the vine. To harvest onions, pull them up from the ground.
