Jerusalem artichokes, also known as sunchokes, are a versatile and hardy plant that can thrive in a variety of environments. They are particularly well-suited for container gardening, which allows you to control their growth and enjoy their delicious tubers without worrying about them taking over your garden. In this guide, we’ll walk you through the process of growing Jerusalem artichokes in containers and pots.
Understanding Jerusalem Artichokes
Before we dive into the planting process, it’s important to understand what Jerusalem artichokes are and why they’re a great choice for container gardening. Despite their name, Jerusalem artichokes are not from Jerusalem, nor are they artichokes. They are a type of sunflower native to North America, known for their tall stalks and bright yellow flowers.
Jerusalem artichokes are grown for their tubers, which are similar in texture to potatoes but have a sweet, nutty flavor. They are high in inulin, a type of fiber that can help regulate blood sugar levels, making them a good choice for diabetics. According to the USDA, they are also a good source of iron and potassium.
Choosing the Right Container
The first step in growing Jerusalem artichokes in containers is choosing the right container. Jerusalem artichokes can grow quite tall – up to 10 feet in some cases – and their tubers can spread out quite a bit, so you’ll need a large, deep container.
According to the University of Minnesota Extension, a container that is at least 15 inches deep and 24 inches in diameter should be sufficient for one plant. If you’re planning to grow multiple plants, you’ll need a larger container or several individual containers.
Material Considerations
The material of your container can also have an impact on your Jerusalem artichokes. Plastic and ceramic pots are both good choices, as they retain moisture well. However, ceramic pots can be quite heavy, so if you plan to move your plants around, plastic might be a better choice.
Wooden containers can also be used, but keep in mind that they may rot over time, especially if they are kept in a wet environment. Metal containers should generally be avoided, as they can heat up in the sun and damage the roots of your plants.
Planting Your Jerusalem Artichokes
Once you’ve chosen your container, it’s time to plant your Jerusalem artichokes. The process is fairly straightforward, but there are a few key steps to ensure success.
- Fill your container with a mix of potting soil and compost. Jerusalem artichokes prefer well-drained soil that is rich in organic matter.
- Plant your tubers about 3-5 inches deep and 12-18 inches apart. If you’re planting multiple tubers in one container, make sure they have plenty of space to spread out.
- Water your tubers thoroughly after planting, and keep the soil consistently moist (but not waterlogged) throughout the growing season.
- Place your container in a sunny spot. Jerusalem artichokes need at least 6 hours of sunlight per day to thrive.
Caring for Your Jerusalem Artichokes
Once your Jerusalem artichokes are planted, they require relatively little care. However, there are a few things you can do to ensure a healthy, productive crop.
Watering
Jerusalem artichokes are fairly drought-tolerant, but they do best with consistent moisture. Aim to water your plants once a week, or more often if the soil dries out quickly. However, be careful not to overwater, as this can lead to root rot.
Fertilizing
Jerusalem artichokes are not heavy feeders, but they do benefit from a bit of extra nutrition. A balanced organic fertilizer applied at planting time and again in midsummer should be sufficient.
Pest and Disease Control
Jerusalem artichokes are relatively pest and disease resistant. However, they can occasionally be affected by pests like aphids or diseases like powdery mildew. If you notice any signs of these problems, treat them promptly with an appropriate organic pesticide or fungicide.
Harvesting Your Jerusalem Artichokes
Jerusalem artichokes are typically ready to harvest in late fall, after the first frost has killed off the tops of the plants. To harvest, simply dig up the tubers with a garden fork or your hands. Be careful not to damage the tubers, as they can bruise easily.
Once harvested, Jerusalem artichokes can be stored in a cool, dark place for several months. They can be eaten raw or cooked, and are a delicious addition to soups, stews, and stir-fries.
Conclusion
Growing Jerusalem artichokes in containers is a rewarding and relatively easy gardening project. With the right container, a sunny spot, and a bit of care, you can enjoy a bountiful harvest of these delicious and nutritious tubers. So why not give it a try? You might just find that Jerusalem artichokes become a new favorite in your garden – and your kitchen.
