Introduction
When it comes to growing potatoes, many gardeners often focus solely on the potato plants themselves. However, incorporating companion plants into your potato garden can provide numerous benefits, such as improving soil fertility, attracting beneficial insects, and deterring pests. In this article, we will explore some of the best companion plants for potatoes in 2023, along with their benefits and how to effectively incorporate them into your garden.
1. Marigolds
Marigolds are a popular companion plant for potatoes due to their ability to repel nematodes, which are microscopic worms that can damage potato roots. Additionally, marigolds attract beneficial insects like ladybugs and lacewings, which prey on potato pests such as aphids and Colorado potato beetles. Plant marigolds around the perimeter of your potato patch to reap these benefits.
2. Horseradish
Horseradish is an excellent companion plant for potatoes as it deters the Colorado potato beetle, a notorious potato pest. The strong scent of horseradish repels these beetles, reducing the chances of an infestation. Plant horseradish near your potato plants or interplant them for maximum effect.
3. Beans
Beans are nitrogen-fixing plants, meaning they convert nitrogen from the air into a form that can be absorbed by plants. Potatoes require a good amount of nitrogen, making beans an ideal companion. Interplanting beans with potatoes can help improve soil fertility and enhance the growth and yield of your potato plants.
4. Nasturtiums
Nasturtiums are not only beautiful, but they also serve as a natural insect repellent. These vibrant flowers repel aphids, Colorado potato beetles, and other pests that can harm your potatoes. Plant nasturtiums near your potato plants to create a visually appealing and pest-free potato garden.
5. Chives
Chives are known for their ability to deter pests like aphids and spider mites. These onion-family plants emit a strong odor that repels insects. Interplanting chives with potatoes can help protect your potato plants from these common pests and enhance their overall health.
6. Tansy
Tansy is a perennial herb that can deter a wide range of pests, including ants, Colorado potato beetles, and squash bugs. Its strong scent and bitter taste repel these pests, making it an excellent companion plant for potatoes. Plant tansy around your potato patch or use its leaves as a natural pest repellent mulch.
7. Borage
Borage is a beautiful flowering herb that attracts bees, which are essential for pollinating potato plants. Improved pollination can lead to increased potato yields. Additionally, borage repels tomato hornworms, a pest that can also affect potatoes. Plant borage near your potato plants to attract pollinators and deter pests.
8. Calendula
Calendula, also known as pot marigold, is another companion plant that attracts beneficial insects like hoverflies and parasitic wasps. These insects prey on aphids, caterpillars, and other pests that can damage potato plants. Plant calendula near your potatoes to create a diverse and thriving ecosystem in your garden.
9. Green Manure Cover Crops
Consider planting green manure cover crops, such as clover or vetch, after harvesting your potatoes. These cover crops help suppress weeds, improve soil structure, and provide additional organic matter when tilled into the soil. They also fix nitrogen, enriching the soil for future potato plantings.
Conclusion
By incorporating companion plants into your potato garden, you can create a balanced and thriving ecosystem that benefits both your potatoes and the environment. From repelling pests to improving soil fertility and attracting beneficial insects, companion plants offer numerous advantages. Experiment with different combinations of companion plants and observe the positive impact they have on your potato garden in 2023 and beyond.
