One of my leeks has developed small nodules on the underside of a couple of its leaves. It's difficult to tell if there is any lesion on the upper side of the leaf but when I cut it open there was no sign of any grub or creature in it. Any idea of what might have caused this? I get some leek moth but this plant had none of the usual signs of leek moth attack.

They look like "cucullations", a sort of a wrinkle that shows up sometimes as the leaf develops in the center bud. Usually harmless, but large numbers may be a symptom of mites.

Thanks for your replies. Yes, it certainly didn't put me off eating it.

The leek looks fine to me. Enjoy it with potato in soup, and ignore the lump. We all have 'em, to a greater or lesser degree. That leek looks so healthy, it can't have affected its growth or development. Worthy
