Jerusalem Artichoke Plant Care

Jerusalem Artichoke (Helianthus tuberosus) belongs to the Asteraceae family within the Helianthus genus. Jerusalem Artichoke is native to North America. Jerusalem Artichoke is also known as Sunchoke, Topinambur, Girasol.

Jerusalem Artichoke displays an upright, spreading growth habit, reaching up to 6 inches tall with a spread of approximately 3 inches. Jerusalem Artichoke produces large, yellow, daisy-like flower heads.

Leaf size: approximately 8 inches.

Helianthus tuberosus requires watering every 7–10 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Jerusalem Artichoke thrives in full sun light conditions. The optimal light range is 2000–5000 lux. Avoid placing Jerusalem Artichoke in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Helianthus tuberosus grows best at temperatures between 50°F and 85°F. Jerusalem Artichoke prefers humidity levels of 40–60%.

Well-draining soil mix. Good drainage is essential for Jerusalem Artichoke to prevent waterlogging, which leads to root rot and fungal issues.

Repot every 2-3 years in early spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.

Jerusalem Artichoke can be propagated through by division or from tubers. Similar propagation techniques also apply to sunflower plant care, which shares the same genus.

Jerusalem Artichoke is susceptible to aphids, caterpillars, powdery mildew. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Jerusalem Artichoke grows outdoors in USDA Zone 3a – 9b. Native to North America, Jerusalem Artichoke is adapted to warm climates. In cooler regions, grow Jerusalem Artichoke as a houseplant or bring it indoors before the first frost.
