Why does this happen, and what is it called when it does? After a laugh at this particular specimen from Chris Parker and his wife Kelli’s garden, our resident gardening expert Pete Amyoony explains. Nobs on carrots can be caused be either a tap root hitting a stone on the way down, or by soil that is too rich in fertilizer. Parker says he was encouraged to not add any more manure to his garden for a couple of years, and with crop rotation, the problem will look after itself.
