Jerusalem artichokes, also known as sunroots, are a unique and tasty addition to any garden. These perennial plants are easy to grow, requiring minimal care once established. Their tubers, which taste like a cross between potatoes and garlic, are versatile in the kitchen.
Jerusalem artichokes thrive in full sun and well-drained soil. They are drought-tolerant but prefer moderate moisture. These hardy plants can survive temperatures as low as 0°F (-18°C), making them suitable for most temperate climates.
Plant Jerusalem artichoke tubers about a foot apart, with the bud end up, in early spring or fall. Water deeply after planting and maintain consistent moisture until growth emerges. Avoid fertilizing, as this can lead to lush top growth at the expense of tuber development.
Jerusalem artichokes rarely suffer from pests or diseases, making them a low-maintenance choice for your garden. The main issue is overcrowding, which leads to smaller tubers. To prevent this, dig up and divide clumps every few years.
Tubers are ready to harvest when the plants have died back in fall, usually 4-6 months after planting. Gently dig up and brush off excess soil. Jerusalem artichokes can be stored like potatoes for a few months or used fresh immediately.
