Can I plant tomatoes next to corn?

When planning your garden, it is essential to consider the impact of companion planting on your crops. Companion planting is the practice of growing different plants together to provide mutual benefits that promote health and growth. One common question many gardeners have is whether they can plant tomatoes next to corn. The answer is yes, with some caveats.

Why plant tomatoes next to corn?

Tomatoes and corn make excellent companions because they have different nutrient requirements. Corn is a heavy feeder of nitrogen, while tomatoes require more phosphorus and potassium. When planted next to each other, corn and tomato plants can help each other by sharing nutrients from the soil.

Additionally, planting these two crops together can also help with pests. Corn earworm and tomato fruitworm have similar life cycles and are usually active during the same period of the growing season. By planting them together, the pests will not be able to focus on one crop, reducing the overall damage.

Considerations when planting tomatoes next to corn

When planting tomatoes next to corn, it is crucial to ensure that each plant has adequate space to grow. Corn plants can grow tall and shade smaller plants, such as tomatoes, from the sun. Additionally, corn has an extensive root system that can compete with tomato roots for nutrients from the soil. To avoid this issue, plant the corn first and then wait until it has reached a height of at least 12 inches before planting the tomato seedlings.

Another consideration is the type of tomato to plant next to corn. Indeterminate varieties, which grow tall and require staking or caging, are best suited for planting next to corn. Determinate varieties, which have a bushier growth habit, do not require as much vertical space but may get shaded by corn plants. Dwarf varieties may not be suitable for planting next to corn since they have stunted growth and may not compete well with the corn plants.

Conclusion

Planting tomatoes next to corn can be an excellent way to maximize space in your garden and promote healthy growth. By understanding the nutrient requirements of each plant and providing adequate spacing, you can use their differences to your advantage. With the right planning and preparation, you can enjoy a bountiful harvest of both crops.
