Jerusalem artichoke slug damage

Hi

This is my first year growing these. The first lot I had a few weeks ago were fine but the ones I dug up yesterday had a lot of slug damage. I wanted to keep them in the ground until needed because I assume they stay fresher that way. Am I better off digging them up and storing them to avoid the slug damage or do they not normally get that damaged?

Sorry to hear about the slug damage; the holed ones should be ok to plant in March for next years crop, meanwhile if you can find any decent ones, wash them off and store outside in a bag of damp compost so they're easier to grab during the frosty weather. The longer they're in the ground the more likely the slugs will find them.
