Grooves in Potato Tubers

peter_6August 13, 2010

This year about one in ten of my potatoes has a groove rather like an old wound that has healed without the sides kniting up. I didn't cause it by, for example, I didn't cut them with a spade when they were half-grown. I've been growing potatoes in this garden for a dozen years without this effect. All I can observe that is different this year is lots of rain early, and growing the potatoes in a bed with lots of quack-grass in it. Any ideas as to what the cause might be? Regards, Peter.

Thank you for reporting this comment. Undo

I have always observed those. As you suggest, perhaps a result of coming up against aggressive grass roots. Sometimes I find a tuber pierced right through by those roots.
