An old timer told me if you wait until after the first frost to harvest the tubers they cause much less flatulence. He said before the first frost they call them fartichokes. : ) Planting for the first time this year and will definitely apply this advice.

I bought 5 tubers from Amazon, they're huge, about 4" wide! Can I cut them to make more plantings? Also, it says to plant in February, how do I store then until then? Don't want them to rot!

Store them in a pot of dry dirt. Cut them a cpl days before planting to allow the cut to scab over. best if you can dip wet cut in wood ash so that insects dont find it attractive.

I live on the Alabama Gulf Coast, and just bought 4lb Jerusalem Artichokes for planting. Can I plant now (October) or if I need to wait until Spring, how should I store them? Should I mulch if I plant now? Thank You

I finally got some Jerusalem Artichokes from a grocery store for $4.99 a pound and cooked them. I like them but primarily because my doctor called them a Superfood for me. But saved 4 to plant is it too late, April to October, right?

There's a yellow flowering bush that looks like Jerusalem Artichoke that grows wild around northern rivers- Uki NSW Australia that seems similar but flower looks a bit bigger & grows quite tall & I think the leaves are wider with a different shape, not ovste like the Sunchoke. Does anyone know if these plants that can run rampant are from the same family as the Jerusalem Artichoke?
