Has anyone had experience growing Jerusalem Artichokes? Any problems with them, such as spreading into areas you don't want them to be, etc? Are they as good as the catalogs say? We are in a dry area of Colorado, but have the capabilities of watering, so I would like to try them this year. Would they stand up to cold, dry winters? Do they need to be mulched? If you don't dig up the entire crop for use/storage during the winter, would they come back the next year? How do you know when they are ready to harvest? Thanks for any info, this is a great site to gain from other's knowledge and experience! Jan(posted 9010 days ago)
