Some pest is voraciously consuming my Komatsuna. It must be nocturnal as I can find no trace other than stripped plants. Any suggestions!
Earwigs? I had the same problem with some plants and checked it out at night and sure enough covered in them. Never saw them otherwise.
I occasionally run into this problem in my greenhouses and discovered that pill/sow bugs that are staying nice and warm were making a meal of any tender shoots, or in some cases stripping seedlings entirely. They like to hide during the day in the nooks and crannies and when they come out at night they devour what every they find that is edible.
