Plant Care & Growing Tips

Successfully growing crosnes tubers requires attention to a few key environmental factors, primarily consistent moisture and adequate sunlight. These plants thrive when their specific needs are met, rewarding you with abundant harvests of delicious tubers. For optimal yield and quality, ensure your planting site receives full sun. While tuberous mints can tolerate some shade, they won’t produce as many tubers without ample sunlight, which provides the energy needed for robust growth.

Watering is crucial for stachys affinis. A consistent supply of water is necessary to produce good yields; if the soil is allowed to dry out too frequently, tuber development will suffer. Aim for consistently moist, but not waterlogged, soil. Well-draining soil is essential to prevent rot, especially in areas with heavy rainfall. These tubers are hardy down to USDA zone 6, meaning they can withstand temperatures into the lower 20s F (less than -4 C) as long as they are planted deep enough to be protected from shallow freezing. The foliage will die back with colder temperatures, but the tubers remain viable underground.

When planting your chinese artichoke tubers, consider row spacing of nine to fifteen inches (22.5 to 37.5 cm) apart. Tighter spacing can be used if water is abundant, but a wider spacing, such as fifteen inches, often encourages the development of larger tubers. A thirty-inch (75 cm) row spacing will also provide a comfortable walkway between rows, facilitating easier harvesting and maintenance. Fertilization can be done with a balanced organic fertilizer at planting and again mid-season to support vigorous growth and tuber formation.

Size & Details

The crosnes tubers provided are ideal for planting and establishing your own patch of this unique vegetable. Each tuber is generally small, ranging from two to three inches (5 to 7.5 cm) in length and approximately half an inch (1.2 cm) wide, characteristic of healthy Stachys affinis. These tubers are shipped dormant, ready to be planted upon arrival to ensure the best start for your future harvest. When mature, the plants will typically reach a modest height, with the primary focus being on the underground tuber production.

Expect your chinese artichoke tubers to begin producing edible rhizomes in the fall and winter following spring planting. The plant’s foliage will die back as temperatures drop, indicating the tubers are ready for harvest. With proper care and ideal conditions, you can anticipate a generous yield of these crisp, nutty delights, perfect for fresh consumption or various culinary preparations. These are living plant material, so prompt planting is recommended to ensure successful establishment and growth of your edible tubers.
