Corn and potatoes are two of the most popular vegetables grown in home gardens. They are both easy to grow and can be grown in a variety of climates. When planted together, corn and potatoes can benefit from each other’s presence, creating a symbiotic relationship that results in higher yields of both crops.
Benefits of Planting Corn with Potatoes
There are several benefits to planting corn with potatoes, including:
- Improved soil fertility: Corn and potatoes have different nutrient needs. Corn requires nitrogen, while potatoes require phosphorus and potassium. When planted together, these two crops can help to improve the overall fertility of the soil.
- Increased yields: Studies have shown that planting corn with potatoes can result in higher yields of both crops. This is likely due to the fact that the two crops can help to protect each other from pests and diseases.
- Reduced weed pressure: Corn and potatoes can both help to suppress weeds. Corn stalks can shade out weeds, while potato plants can release chemicals that inhibit weed growth.
- Improved water retention: The leaves of corn plants can help to shade the soil, which can help to retain moisture. This can be especially beneficial in dry climates.
How to Plant Corn and Potatoes
Planting corn and potatoes together is easy. Here are the steps:
1. Choose a sunny location: Corn and potatoes both need full sun to grow well.
2. Prepare the soil: The soil should be well-drained and have a pH of 6.0 to 6.5.
3. Plant the corn: Corn should be planted in rows that are 3 feet apart. The seeds should be planted 6 inches apart in the rows.
4. Plant the potatoes: Potatoes should be planted in rows that are 2 feet apart. The seed potatoes should be planted 12 inches apart in the rows.
5. Water the plants: The plants should be watered regularly, especially during hot, dry weather.
6. Fertilize the plants: Corn and potatoes both need fertilizer. A balanced fertilizer can be applied every few weeks.
7. Harvest the crops: Corn is ready to harvest when the ears are full and the kernels are milky. Potatoes are ready to harvest when the vines have died back and the skins are firm.
Companion Planting with Corn and Potatoes
Corn and potatoes can be planted with a variety of other vegetables, including beans, tomatoes, and squash. These companion plants can help to improve the growth and yield of corn and potatoes.
- Beans: Beans are a good companion plant for corn because they can help to fix nitrogen in the soil. Nitrogen is an essential nutrient for corn.
- Tomatoes: Tomatoes are a good companion plant for potatoes because they can help to deter pests. Tomatoes release chemicals that can repel insects.
