What Not To Plant With Nasturtiums

Certain plants may not thrive when planted alongside nasturtiums, so it’s essential to be aware of these potential companions. Here are some plants you should avoid planting with nasturtiums:

1. Tomatoes: Nasturtiums release a chemical that can inhibit the growth of nearby tomato plants. This chemical, known as allelopathy, can negatively affect the development of tomatoes and reduce their yield.
2. Cabbage: Nasturtiums can attract pests such as cabbage white butterflies, which lay their eggs on cabbage plants. This can lead to an infestation and damage to your cabbage crop.
3. Radishes: Nasturtiums and radishes have similar growing conditions, which can result in competition for nutrients and space. Planting them together may hinder the growth of both plants.
4. Beans: Nasturtiums have a tendency to climb and spread, which can overshadow and smother the growth of bean plants. It’s best to keep these two plants separate to ensure optimal growth.
5. Carrots: Nasturtiums have a deep root system that can compete with carrots for nutrients in the soil. Planting them together may result in stunted carrot growth.
6. Peppers: Nasturtiums can attract aphids, which are known to feed on pepper plants. Planting these two together may increase the risk of aphid infestation.
7. Lettuce: Nasturtiums have a sprawling growth habit that can overshadow and shade lettuce plants. This can hinder their growth and reduce their overall quality.
8. Spinach: Nasturtiums prefer full sun, while spinach thrives in partial shade. Planting them together may result in uneven growth and reduced productivity for both plants.
9. Parsley: Nasturtiums can outcompete parsley for nutrients and space, leading to stunted growth and reduced yield for both plants.
10. Beets: Nasturtiums have a spreading growth habit that can crowd and shade beet plants. This can result in poor beet development and smaller yields.
11. Onions: Nasturtiums can attract onion flies, which lay their eggs on onion plants. This can lead to an infestation and damage to your onion crop.
12. Marigolds: While marigolds are often used as companion plants to deter pests, they may compete with nasturtiums for resources. It’s best to plant them separately to ensure optimal growth for both plants.

By avoiding planting these plants alongside nasturtiums, you can create a harmonious garden where each plant can thrive without hindering the growth of others.
