If roots like ginger and potato grow in dirt, why are there almost never worms in those that I buy in the grocery store?

I tried growing fresh ginger a few times in dirt (often after letting it dry up for a few hours. usually a few seconds in worms start trying to decompose it and I find many univited guests munching kn kt. How the hell do farmers get these roots not worm infested?

Earthworms have food preferences…they’re pickier than you might think. What exactly they want to eat when is a topic of active research (http://news.bbc.co.uk/earth/hi/earth_news/newsid_8694000/8694377.stm) but they generally appear to prefer dead stuff to live stuff, to the point that scientists were surprised when they found out they will eat live seeds & plants.

So if you stick dead ginger in your soil the worms will go to town (there are Reddits about earthworm husbandry, have a ball). But a live growing ginger root (or a potato) seems to be less appealing unless they don’t have anything else around that they like better.

I imagine it’s also a lot harder for them to eat a living root with intact skin, since earthworms don’t have teeth and a living root has it’s own defense mechanisms to decay so the worm doesn’t have anything to breach the surface.
