Jerusalem Artichokes, also known as sunroots, sunchoke, or earth apple, are a type of sunflower native to North America. They’re known for their tubers, which are a delicious and nutritious food source. But like all plants, Jerusalem Artichokes can benefit from the right companion plants. In this comprehensive guide, we’ll explore the best and worst companion plants for Jerusalem Artichokes, backed by expert advice and scientific research.
Understanding Companion Planting
Before we delve into the specifics of Jerusalem Artichoke companion plants, it’s crucial to understand the concept of companion planting. This is a time-tested gardening method that involves planting different crops in proximity for pest control, pollination, providing habitat for beneficial creatures, maximizing use of space, and to otherwise increase crop productivity.
Companion planting takes advantage of the natural strengths of certain plants, helping to improve growth, reduce pests, and enhance flavor. It’s a method that’s been used by indigenous peoples for thousands of years, and it’s still relevant in modern organic gardening and farming practices.
Benefits of Companion Planting
Companion planting offers a myriad of benefits. It can help to deter pests naturally, reducing the need for chemical pesticides. Certain plants can also improve the soil by fixing nitrogen, a vital nutrient for many crops. Additionally, companion planting can help to attract beneficial insects, such as bees for pollination, and predatory insects to control pests.
Companion planting can also help to maximize space in your garden. By planting crops with different growth habits together, you can make the most of your available space. For example, planting a tall crop like Jerusalem Artichokes with a low-growing crop can help to utilize vertical space.
Best Companion Plants for Jerusalem Artichokes
Now that we understand the concept and benefits of companion planting, let’s explore the best companion plants for Jerusalem Artichokes. These plants have been chosen based on their compatibility with the growth habit, nutrient needs, and pest resistance of Jerusalem Artichokes.
It’s important to note that while these companion plants can offer many benefits, the success of your garden also depends on other factors such as soil quality, sunlight, and watering practices. Always consider these factors when planning your garden.
Corn
Corn is a great companion plant for Jerusalem Artichokes. Both plants are tall and robust, so they won’t compete for sunlight. Additionally, corn can help to provide some shade for the Jerusalem Artichokes during hot summer months, reducing the risk of sunscald.
Another advantage of planting corn with Jerusalem Artichokes is that they have different harvesting times. Corn is usually harvested in late summer or early fall, while Jerusalem Artichokes are harvested in late fall or winter. This means you can harvest your crops without disturbing the others.
Cucumbers
Cucumbers can also be a good companion for Jerusalem Artichokes. The cucumber vines can grow along the ground, making good use of the space under the tall Jerusalem Artichokes. Additionally, the cucumbers can benefit from the shade provided by the Jerusalem Artichokes, which can help to prevent sunscald.
However, it’s important to ensure that the cucumbers get enough sunlight for growth. Avoid planting them directly under the Jerusalem Artichokes, and instead plant them to the side where they can get some sun.
Plants to Avoid Planting with Jerusalem Artichokes
Just as some plants make great companions for Jerusalem Artichokes, others can cause problems. These plants may compete for resources, attract pests, or otherwise hinder the growth of your Jerusalem Artichokes. Here are a few plants you should avoid planting with Jerusalem Artichokes.
Potatoes
Potatoes and Jerusalem Artichokes both produce tubers, which means they compete for the same resources in the soil. This competition can result in smaller yields for both crops. Additionally, both plants are susceptible to similar pests and diseases, which could lead to a higher risk of problems in your garden.
It’s best to plant potatoes and Jerusalem Artichokes in separate areas of your garden, or in different years if you practice crop rotation.
Tomatoes
Tomatoes and Jerusalem Artichokes are not a good match. Both plants are heavy feeders, meaning they require a lot of nutrients from the soil. If planted together, they can deplete the soil quickly, leading to poor growth and smaller yields.
Additionally, tomatoes prefer a slightly acidic soil, while Jerusalem Artichokes prefer a more neutral to slightly alkaline soil. This difference in soil pH preferences can make it difficult to meet the needs of both plants when they’re planted together.
Final Thoughts
Companion planting is a powerful tool that can help to enhance the productivity and health of your garden. When it comes to Jerusalem Artichokes, choosing the right companion plants can help to maximize growth, deter pests, and make the most of your garden space.
Remember, the success of your garden depends on more than just companion planting. Good soil, adequate sunlight, and proper watering are also crucial. Happy gardening!
