Growing Sunchokes

Sunchokes are related to sunflowers and horticulturalists have for many years tried to reproduce the latter’s spectacular results using the former. Sunchokes grow in moist, acidic soil at low altitudes. They need the cooler conditions of temperate zones and sunny exposure throughout the day to flourish. If you live in an area with sunchoke-friendly growing conditions, you can start harvesting them from your garden as soon as they appear. Sunchokes are members of the nightshade family and caution is advised against consuming too many of them as they can be poisonous. You should also avoid planting sunchoke seeds or berries near any livestock or pets. Sunchokes are perennial shrubs that produce fruits year after year. They grow best in moist, poorly drained soil with a slightly acidic pH level, though they will still do well under average growing conditions if they don’t get too much shade and drainage is improved.

Introduction To Growing Sunchokes

Sunchokes, also known as Jerusalem artichokes, are delicious root vegetables that can be eaten raw, cooked, or processed into a flour. They’re rich in fiber and iron, and are a great addition to any garden. This article will provide a step-by-step guide for how to grow your own sunchokes. Plus, we'll cover the various climate and soil considerations that need to be taken into account when planting sunchokes. Happy gardening!

Choose The Right Location

Sunchokes prefer an area with full sun and well-drained soil. It's best to avoid any areas with standing water or heavy clay, as this can lead to soggy and waterlogged conditions in the soil that may be harmful to your sunchokes. Test the soil pH for optimal results. Sunchokes prefer neutral soil, so aim for a pH between 6 and 7. If necessary, take corrective steps to adjust the pH of your soil to match these parameters.

Prepare The Ground For Planting

When planting sunchokes, begin by loosening the soil and spading it at least 8 inches deep to create a good environment for root growth. To provide extra nutrients, consider incorporating some garden compost or aged manure into the planting area. This will also help to improve the soil’s drainage capability. After loosening the soil and adding any amendments, rake the area to create a flat surface for planting.

Plant The Sunchokes

Sunchokes can be planted from seed or from “sets” — small, young sunchokes. Planting from sets is the most common way, as it generally yields a larger harvest. Planting from sets is easy — simply dig a small hole for each set, and then cover it with soil. Space your sets about 8 inches apart in rows that are 6 inches apart. Water each set lightly, and keep the soil evenly moist until sprouts appear– usually within a week or two.

Mulch The Sunchokes

Once your sunchokes are planted, spread a 2-inch layer of compost, straw, or grass clippings around the plants. This will help to keep the soil moist and to limit the growth of weeds. Additionally, you can add an additional layer of mulch to the top of the bed once the leaves have emerged. This will help to further deter weed growth and will help to maintain the soil temperature.

Fertilize The Sunchokes

Once your sunchokes have sprouted, begin applying a diluted liquid fertilizer every 2 weeks over the course of the growing season. Make sure the fertilizer contains a mix of nitrogen, phosphorus, and potassium. This will help provide an ideal nutrient balance for your sunchokes and will ensure the plants receive necessary nutrients for healthy growth.

Water The Sunchokes

To ensure that your sunchokes receive enough moisture, water them regularly. Aim for an inch of water each week, and adjust the amount depending on your climate and weather conditions. In general, sunchokes prefer a soil that remains consistently moist, but be careful to avoid overwatering or saturating the soil. Once the leaves of the plants begin to dry out, it’s time to water your sunchokes.

Harvest And Store The Sunchokes

Sunchokes can be harvested after 75-100 days of growing. To harvest, simply dig up the plants and remove the sunchokes from the ground. Depending on your climate, sunchokes can be stored in a cool place through winter, although they will keep better when stored in the refrigerator. Be sure to check your sunchokes regularly for any signs of rotting or damage.

Shape And Prune The Sunchokes

To ensure your sunchokes have plenty of room to spread out and plenty of light, it’s important to regularly prune and shape the plants. If necessary, thin or prune any extra shoots or foliage, and remove any dead or yellowing leaves. This will help to ensure your sunchokes are receiving enough light and air and will help to prevent disease or rot.

Prevent Diseases And Pests

To combat any diseases or pests that may be targeting your sunchokes, it’s important to keep the soil around your plants clean. Additionally, make sure your sunchokes aren’t overcrowded, as this can create the perfect environment for disease to take hold. Finally, regularly inspect your sunchokes for signs of disease or pests, and take immediate action if you notice any issues.
