The Benefits of Planting Nasturtiums with Tomatoes

Are you looking for a way to improve the health and productivity of your tomato plants? Then look no further than planting nasturtiums alongside them. Not only are these vibrant flowers a beautiful addition to any garden, but they also provide numerous benefits to your tomato plants.

Pest Control

One of the most significant benefits of planting nasturtiums with tomatoes is their ability to repel pests. Nasturtiums emit a strong scent that deters many types of insects, including aphids, whiteflies, and cucumber beetles. This means that by planting nasturtiums alongside your tomato plants, you can reduce the need for harmful pesticides and protect your plants from damage.

Improves Soil Quality

Another benefit of planting nasturtiums with tomatoes is their ability to improve soil quality. Nasturtiums have deep roots that help to aerate and loosen the soil, making it easier for nutrients and water to reach your tomato plants' roots. Additionally, nasturtiums are known to be excellent at fixing nitrogen in the soil, which is an essential nutrient for healthy plant growth.

Attracts Beneficial Insects

In addition to repelling harmful pests, nasturtiums also attract beneficial insects to your garden. These include bees, butterflies, and ladybugs, all of which play a crucial role in pollinating your tomato plants and controlling other pests that may be present.

How to Plant Nasturtiums with Tomatoes

Now that you know the benefits of planting nasturtiums with tomatoes let's take a look at how to do it.

When to Plant

The best time to plant nasturtiums with tomatoes is in the spring when the soil has warmed up, and there is no danger of frost. You can your nasturtium seeds indoors around four weeks before the last expected frost date in your area, or you can sow them directly outside after the risk of frost has passed.

Where to Plant

Ideally, you should plant your nasturtiums around the perimeter of your tomato bed. This will help to create a barrier that will deter pests from entering and attacking your tomato plants. Alternatively, you can plant them in between your tomato plants, but make sure to leave enough space for both plants to grow.

How to Plant

Planting nasturtiums is relatively easy. Simply dig a hole in the soil, drop the seed in, cover it with soil, and water it well. Make sure to space your seeds or seedlings according to the instructions on the packet to ensure they have enough room to grow.

Caring for Nasturtiums and Tomatoes

Caring for your nasturtiums and tomatoes is crucial if you want them to thrive. Here are some tips to help you care for your plants:


Both nasturtiums and tomatoes need consistent watering to grow well. Water your plants deeply once a week, making sure to soak the soil down to the roots. Avoid watering the leaves, as this can lead to fungal diseases.


Tomatoes require regular fertilization to produce large, juicy fruits. Use a balanced fertilizer with a ratio of 10-10-10, and apply it every two weeks throughout the growing season. Nasturtiums do not need as much fertilizer but can benefit from a light application of compost or organic fertilizer once or twice during the growing season.


Tomatoes require regular pruning to ensure they grow strong and healthy. Remove any suckers that appear in the crotch of the main stem and branches, as these can divert nutrients away from the rest of the plant. Nasturtiums do not require pruning but can benefit from deadheading, which will encourage them to produce more flowers.
