The attached picture shows the state of the leaves on my Ophiopogon planiscapus nigrescens. I have searched during the day and at night, I've plunged the whole pot and plant under water, I've sprayed with Provado but I still haven't found the culprit. Any suggestions as to the identity of my small enemy
I have this problem too. I think it is caused by cutworms, i.e. the caterpillars of large noctuid moths, most often Large Yellow Underwing in UK which hide away during the day and roam about at night. They appear to be relatively impervious to provado, perhaps because they don't bury in soil.
