Nasturtium Companion Vegetables

If you're looking for a way to improve your vegetable garden's health and productivity, consider planting nasturtiums as companion plants. Nasturtiums are annual flowers that produce bright blooms and edible leaves, but they also offer numerous benefits to the vegetables planted beside them.

What Are Companion Plants?

Companion planting refers to the practice of planting different crops together in the same space to take advantage of their natural synergies. Certain plant combinations can enhance soil fertility, deter pests, attract beneficial insects, and improve crop yields.

Benefits of Nasturtium Companion Plants

Nasturtiums are particularly useful as companion plants because they have several unique properties that benefit other vegetables:

1. Pest Control

Nasturtiums contain high levels of mustard oil, which produces a pungent odor that repels many common garden pests, such as aphids, whiteflies, and cucumber beetles. Additionally, nasturtiums can act as a trap crop, luring pests away from more valuable vegetables.

2. Soil Improvement

Nasturtiums have deep roots that help break up compacted soil and improve drainage. They also absorb excess nutrients from the soil, preventing them from leaching into nearby water sources.

3. Pollinator Attraction

Nasturtiums produce brightly colored flowers that attract bees, butterflies, and other pollinators to your garden. This can increase the pollination rate of nearby vegetables, leading to larger and more abundant harvests.

Best Nasturtium Companion Vegetables

While nasturtiums can be planted alongside many different vegetables, some combinations are particularly effective. Here are a few of the best nasturtium companion vegetables:

1. Tomatoes

Tomatoes and nasturtiums make great companions because they have similar growing requirements and pests that affect tomatoes tend to avoid nasturtiums. Additionally, nasturtiums can help repel aphids and whiteflies that commonly plague tomato plants.

2. Cucumbers

Cucumber beetles are a common pest that can cause significant damage to cucumber plants. By planting nasturtiums nearby, you can deter these pests and protect your crop. Additionally, nasturtiums can enhance the flavor of cucumbers when grown together.

3. Radishes

Radishes and nasturtiums are a natural pairing because they have similar soil requirements and grow at a similar rate. Additionally, nasturtiums can help keep flea beetles away from radish leaves, preventing damage to the plant.

How to Plant Nasturtiums as Companion Plants

Planting nasturtiums as companion plants is easy and straightforward. Here's how to get ed:

1. Choose Your Location

Select a spot in your vegetable garden that receives plenty of sunlight and has well-draining soil. Nasturtiums prefer slightly acidic soil with a pH between 6.0 and 7.0.

2. Prepare the Soil

Loosen the soil to a depth of six inches and mix in organic matter, such as compost or aged manure. This will improve soil fertility and drainage.

3. Plant Nasturtium Seeds

Sow nasturtium seeds directly into the soil after the last spring frost. Plant the seeds one inch deep and six inches apart.

4. Maintain Your Plants

Water your nasturtiums regularly to keep the soil moist but not waterlogged. Once the plants begin to flower, deadhead them regularly to encourage new blooms.

Tips for Success

Here are a few additional tips to help you get the most out of your nasturtium companion plants:

  • Don't over-fertilize your nasturtiums, as this can cause excessive leaf growth at the expense of blooms.
  • Plant nasturtiums in areas that receive plenty of sunlight, as they won't flower well in shade.
  • Avoid planting nasturtiums too close to other flowering plants, as they can compete for pollinators.
