I planted 11 sunchoke tubers in late May of this year. They are doing quite well and healthy. I want to harvest them sometime this fall, but I’m wondering if I should wait til next fall after they establish themselves and matured stronger .Is it better for them to establish and mature another year? Or should I go ahead and harvest them this year?
I think in most areas they are grown, they are fine harvested in the first year. I do often leave them another year, but my area is a little cool and wet for them to do well.
If you want to increase your stock, replanting the tubers with increased spacing won't do any harm.
