When deciding what to plant next to nasturtiums, it’s important to consider their specific needs and characteristics. Nasturtiums are a popular choice for gardeners due to their vibrant flowers and edible leaves, but they can also have an impact on nearby plants. Here are some plants that you should avoid planting next to nasturtiums:
1. Brassicas: Nasturtiums belong to the Brassicaceae family, which includes cabbage, broccoli, and cauliflower. These plants can be negatively affected by the presence of nasturtiums. Nasturtiums release a chemical compound called benzyl isothiocyanate, which can inhibit the growth of brassicas. Therefore, it’s best to keep these plants separate to ensure optimal growth for both.
2. Tomatoes: Nasturtiums and tomatoes have different soil and sunlight requirements. Tomatoes prefer full sun and fertile soil, while nasturtiums thrive in poor soils and can tolerate some shade. Additionally, nasturtiums can spread quickly and may overshadow tomato plants, limiting their growth and access to sunlight. It’s best to plant these two separately to avoid competition for resources.
3. Carrots and Parsnips: Nasturtiums have a tendency to attract aphids, which can also affect nearby plants. Carrots and parsnips are particularly susceptible to aphids, so planting them in close proximity to nasturtiums can increase the risk of infestation. To prevent this, it’s advisable to keep these root vegetables away from nasturtiums.
4. Pole Beans: While nasturtiums can be beneficial for some plants, they can have a detrimental effect on pole beans. Nasturtiums are known to attract black bean aphids, which can spread diseases to pole beans and stunt their growth. To protect your pole beans, it’s best to keep them away from nasturtiums.
In general, it’s important to consider the specific needs and interactions of plants when planning your garden. While nasturtiums can be a lovely addition, it’s best to keep them separate from plants that may be negatively affected by their presence. By carefully planning your garden layout, you can ensure the health and vitality of all your plants.
