Companion Plants for Potatoes

If you're planting potatoes, it's important to consider companion plants. Companion planting can help to boost soil health, deter pests, and even improve the flavor of your potatoes. Here are some companion plants to consider planting next to your potatoes:

1. Beans

Beans make great companions for potatoes as they help to fix nitrogen in the soil, which can be beneficial for the growth of the potatoes. Additionally, the vining nature of pole beans can provide a trellis for potatoes to climb, saving space in the garden.

2. Marigolds

Marigolds are known for their pest-repelling properties, and planting them next to your potatoes can help to deter pests that would otherwise be attracted to the potatoes. Marigolds also release a chemical that can improve the flavor of your potatoes.

3. Garlic

Garlic is another pest deterrent that can be planted next to potatoes. It has a natural compound called allicin that repels pests like aphids, potato bugs, and spider mites. Garlic also has a compound called ajoene that can help to prevent soilborne diseases that can affect potatoes.

4. Corn

Planting corn next to your potatoes can help to provide shade for the potatoes during hot summer days. Additionally, the tall stalks of corn can provide a trellis for the potatoes to climb. Just be sure to plant the corn several weeks after the potatoes, as they can compete for the same nutrients if planted at the same time.

5. Nasturtiums

Nasturtiums are a great companion plant for potatoes as they can help to deter pests like aphids and whiteflies. Additionally, the flowers and leaves of nasturtiums are edible and can add a spicy flavor to your salads.

When planting companion plants next to your potatoes, be sure to space them out accordingly and avoid overcrowding. Additionally, consider rotating your crops each year to prevent the buildup of pests and diseases in the soil. With the right companion plants, you can ensure a healthy and bountiful potato harvest.
