Growing Instructions 


Sun Exposure: Full sun.
Soil: Soil pH from 5.8-6.2Prefers loose well drained soil, but will grow almost anywhere. Loose soil will make harvesting easier.
Moisture: Prefer even regular supply of water, but can survive long periods of drought once the plants are established.
Planting: Sunchokes can be planted as early as 2-3 weeks before the average last frost date in the spring. Cut down flowers as soon as they appear to encourage the tubers to grow instead of the production of seeds.
Spacing: Plant tubers 12-18 inches apart. Space rows 36 inches apart.
Sow seeds: Plant tubers 2-6 inches deep.



Tubers are ready for harvest when the leaves die back. Sunchokes harvested after a light frost will have a sweeter, nuttier taste. Use a pitchfork to lift tubers from the ground. Tubers left in the ground will grow the following season.


Freshly harvested sunchokes will last in the refrigerator for 7-10 days. Sunchokes can be stored in cool moist places, such as a root cellar, for up to 2-5 months. 

Sunchokes freeze well and can also be pickled or fermented.


Corn, peanuts and rhubarb. Avoid planting with tomatoes.
