When it comes to planting tomatoes, it’s important to consider the plants that you should avoid planting near them. Certain plants can have a negative impact on the growth and overall health of your tomatoes. In this article, we will discuss what not to plant near tomatoes and why.
One plant that should never be planted near tomatoes is potatoes. Both tomatoes and potatoes belong to the nightshade family, and planting them together increases the risk of diseases such as blight. These diseases can quickly spread from one plant to another, leading to poor yields and even plant death.
Cabbage is another plant that should be kept away from tomatoes. Cabbages are heavy feeders and can compete with tomatoes for nutrients in the soil. This can result in stunted growth and reduced fruit production for both plants. Additionally, cabbage worms and other pests that are attracted to cabbage can also harm tomato plants.
Fennel is known for its strong aroma, which can attract pests like aphids. Planting fennel near tomatoes can attract aphids to your tomato plants, leading to an infestation. Aphids can suck the sap from tomato plants, causing them to weaken and become susceptible to diseases.
While corn can provide shade for tomatoes, it’s best to keep them separate. Corn is a heavy feeder that requires a lot of nutrients from the soil. Planting corn near tomatoes can deplete the soil of essential nutrients, leaving the tomatoes nutrient deficient and more vulnerable to diseases.
Dill is a herb that can inhibit the growth of tomatoes. It releases chemicals that can stunt the growth of tomato plants and reduce their overall productivity. To ensure healthy tomato plants, it’s best to keep dill away from them.
Kohlrabi, a member of the cabbage family, should be avoided when planting tomatoes. Like cabbage, kohlrabi competes with tomatoes for nutrients in the soil. This can result in weaker plants and a lower yield for both crops.
Walnut trees release a chemical called juglone, which can be toxic to many plants, including tomatoes. Planting tomatoes near walnut trees or in soil that has been in contact with walnut roots can cause the leaves of the tomato plants to wilt and turn yellow. It’s best to keep tomatoes away from walnut trees.
Although sunflowers can attract pollinators and provide shade, they can also compete with tomatoes for water and nutrients. Sunflowers have an extensive root system that can deplete the soil of essential nutrients, leaving tomatoes nutrient deficient.
While tomatoes and peppers are often planted together in companion planting, it’s best to avoid planting them too close. Peppers can attract pests like aphids and tomato fruitworms, which can also harm tomato plants. Additionally, peppers and tomatoes have similar nutrient requirements, so planting them together can lead to competition for resources.
Knowing what not to plant near tomatoes is crucial for their optimal growth and productivity. Avoiding plants like potatoes, cabbage, fennel, corn, dill, kohlrabi, walnuts, sunflowers, and peppers will help ensure that your tomato plants thrive and produce an abundant harvest. By carefully planning your garden layout and considering plant compatibility, you can create a healthy and productive tomato garden.
