Corn, scientifically known as Zea mays, is a versatile crop that has been a staple in human diets for centuries. Known for its golden ears and bountiful harvests, corn is a plant that demands attention when it comes to planting. However, not all plant companions support the successful growth and development of corn. In fact, certain plants can inhibit its growth, attract pests, or compete for vital resources. This article delves into the world of what not to plant next to corn, shedding light on the detrimental effects of improper companion planting and providing valuable insights for ensuring a flourishing corn crop. So, whether you are a seasoned farmer, a curious gardener, or simply an enthusiast of agriculture, read on to discover the importance of careful selection when it comes to corn’s neighboring plants.
key Takeaways
- Growing beans next to corn can lead to nitrogen deficiency in the soil.

- Intercropping corn with squash or pumpkins can be beneficial as they can help deter pests.
- Avoid planting potatoes near corn as they both attract similar pests and diseases.
- Planting cucumbers next to corn can lead to reduced yields due to competition for sunlight and nutrients.
- Interplanting corn with herbs like basil or marigold can help repel insects.
- Do not grow peppers near corn as they are susceptible to similar diseases.
- Avoid planting melons near corn as they can be affected by the same pests.
- Interplanting corn with tall-growing crops like pole beans or sunflowers can provide shade and support.
What crops should not be planted near corn?
Corn is a widely grown crop that requires careful consideration when planning its companion plants. There are certain crops that should not be planted near corn due to potential negative effects on growth, yield, or susceptibility to pests and diseases. Understanding which crops to avoid planting next to corn can help maximize the success of your corn harvest. Let’s explore some of the crops that are not recommended to be grown in close proximity to corn.
Tomatoes
Tomatoes are prone to a disease called corn stunt, which can be transmitted to them through the soil. As corn is one of the host plants for this disease, planting tomatoes near corn increases the risk of infection. Additionally, corn’s tall stature can shade the tomatoes, limiting their sunlight exposure and growth potential.
Beans
Beans, specifically pole beans, should not be planted near corn as they both require vertical support for optimal growth. When planted together, the climbing beans can intertwine with the corn stalks, making it difficult to harvest both crops. Moreover, the beans may compete with corn for nutrients and water, potentially reducing the overall yield.
Cucumbers
Cucumbers are another crop to avoid planting near corn. Corn has high water requirements and planting cucumbers alongside can lead to increased competition for water, affecting the growth and productivity of both plants. Furthermore, the vines of cucumbers may spread onto the corn, hindering its development and making it challenging to harvest.
Peppers
Pepper plants, especially sweet bell peppers, are not recommended to be grown near corn due to potential cross-pollination issues. Corn is wind-pollinated, and its pollen can reach the flowers of pepper plants, resulting in hybrid fruits with altered characteristics. To maintain pure pepper varieties, it is advisable to keep them at a safe distance from corn.
Onions
Onions are incompatible neighbors for corn due to their different growth requirements. Onions prefer well-drained soil, while corn requires a more moisture-retentive soil type. Planting onions near corn can result in water imbalance, affecting the growth and health of both crops. It is best to separate these two plants to avoid potential damage.
Conclusion
To ensure the successful growth of corn, it is crucial to select appropriate companion plants. Avoiding crops such as tomatoes, beans, cucumbers, peppers, and onions near corn can help prevent diseases, competition for resources, and detrimental cross-pollination. By being mindful of the plants to avoid, you can create a harmonious environment for your corn crop, leading to healthier plants and a higher yield.
FAQs About What Not To Plant Next To Corn
1. Can I plant tomatoes next to corn?
Although tomatoes and corn are often grown together in home gardens, it is not recommended to plant them next to each other. Corn and tomatoes are both heavy feeders, meaning they require a lot of nutrients from the soil. When planted together, they can compete for these nutrients, leading to decreased growth and yield for both crops. Additionally, planting tomatoes next to corn can increase the risk of diseases such as corn smut and tomato blight.
2. Is it okay to plant beans near corn?
Planting beans next to corn can actually be beneficial for both crops. Beans are nitrogen-fixing plants, which means they have the ability to convert nitrogen from the air into a form that other plants can use. Corn requires a significant amount of nitrogen for healthy growth, and planting beans near corn can provide a natural source of nitrogen for the corn. This symbiotic relationship, known as companion planting, can result in improved growth and yield for both crops.
3. Are there any plants that can help deter pests from corn?
Yes, there are several plants that can help deter pests from corn. One example is marigolds, which release a scent that repels many common garden pests. Planting marigolds near corn can help protect the crop from insects like corn earworms and aphids. Another plant that can be used as a natural pest deterrent is mint. Mint’s strong scent can help repel pests like mice and deer. However, it’s important to note that mint can be invasive, so it should be planted in containers or confined areas to prevent it from spreading and taking over the garden.
4. Why is it not recommended to plant corn next to potatoes?
Planting corn next to potatoes is not recommended because both crops are susceptible to diseases and pests that can easily spread between them. For example, corn is susceptible to corn smut, a fungal disease that can also infect potatoes. Similarly, potatoes are prone to diseases like late blight, which can also affect corn. Planting these crops near each other increases the risk of spreading these diseases, leading to decreased yields and potentially crop loss.
5. Can I plant cucumbers next to corn?
It is generally not recommended to plant cucumbers next to corn. Cucumbers are considered heavy feeders, requiring a lot of nutrients from the soil. When planted near corn, they may compete for these nutrients, resulting in decreased growth and yield for both crops. Additionally, cucumbers can be susceptible to diseases like bacterial wilt, which can also affect corn. To avoid these issues, it is best to provide enough space between corn and cucumbers, or consider alternative companion plants that are more compatible with both crops.
Different Corn Varieties for Optimal Results
There are several different varieties of corn available, each with its own unique characteristics and benefits. Here are some popular corn varieties and their uses:
Sweet Corn:
Sweet corn is the most common type of corn grown for human consumption. It is harvested when the kernels are still immature and tender. There are many different varieties of sweet corn, including supersweet, sugary enhanced, and standard sweet corn. Supersweet corn has an extremely high sugar content, resulting in a very sweet and crisp taste.
Popcorn:
Popcorn is a type of corn that is specifically grown for its ability to pop when heated. The kernels are smaller and harder than sweet corn, and they have a hull that traps steam when heated, causing them to explode and turn into popcorn. Popcorn varieties are typically classified as either butterfly or mushroom type, based on the shape of the popped kernels.
Flint Corn:
Flint corn, also known as Indian corn, is grown primarily for its decorative purposes. It is characterized by its hard, colored kernels. Flint corn varieties come in a wide range of vibrant colors, including red, blue, yellow, and multi-colored. While flint corn is not typically eaten directly, it can be used for making cornmeal, flour, or ornamental crafts.
Dent Corn:
Dent corn, also known as field corn, is primarily grown as animal feed or for industrial uses. It gets its name from the distinctive dent that forms in the top of each kernel as it dries. Dent corn is often used in the production of cornmeal, corn oil, and ethanol. It can also be used to make products such as cornstarch, corn syrup, and tortilla chips.
