Cultivating Jerusalem Artichokes: A Step-by-Step Guide
Jerusalem artichokes, also known as 'fartichokes' due to their unique effects on digestion, are a fascinating and nutritious addition to any garden. Originating from cooler parts of North America, these tuberous sunflowers (Helianthus tuberosus) are not only easy to grow but also offer a wealth of benefits.
To begin growing Jerusalem artichokes, choose and prepare a planting site with well-drained soil and good sunlight exposure. While these hardy plants can thrive in various soils, they prefer loose, fertile soil for optimal tuber development.
Next, plant the tubers 10-15 cm (4-6 inches) deep and space them about 30 cm (1 foot) apart. You can plant in rows or staggered rows for better growth and access. Timing is crucial - plant the tubers about 2 to 3 weeks before the average last frost in spring.
Jerusalem artichokes require minimal care. Protect emerging shoots from slugs and snails, especially young growth. Prune tall stems in late summer if exposed to wind to avoid damage and encourage tuber growth.
Harvest time arrives after foliage yellows in autumn. Cut stems down to about 8 cm (3 inches) to mark the tuber locations, mulch over them for winter protection, then dig up when needed.
These versatile plants can be eaten raw or cooked in soups and stews. They are rich in iron and potassium, and instead of starch, they contain the carbohydrate inulin. Interestingly, inulin is not easily digested by humans, which can lead to flatulence.
Jerusalem artichokes are a sustainable crop choice, as they can be planted year after year. They can be stored in cold areas under a thick surface mulch, or lifted and stored in boxes of damp sand.
In conclusion, propagation is done by planting tubers directly in the soil, spaced properly and planted before the last frost, with minimal maintenance required for a good harvest. With their pretty flowers that attract pollinators, Jerusalem artichokes are not only a delicious and nutritious food source but also a beautiful addition to any garden.
Online retailers such as Thompson & Morgan, Suttons, and Crocus offer Jerusalem artichoke tubers for purchase, making it easy for gardeners to grow this unique plant in their own backyards. Earthing up Jerusalem artichoke plants may increase harvest, so consider this practice if you want a bountiful yield.
Planting Jerusalem artichokes, a fascinating ‘home-and-garden’ addition known for its unique nutritional benefits, is done by purchasing tubers from online retailers like Thompson & Morgan, Suttons, or Crocus. To thrive, these plants require well-drained soil, ideal for ‘gardening’ in loamy, fertile ground, with careful spacing and timing for optimal tuber development.
