Hey, I was wondering why there are holes and black dots on my cilantro.... is it bugs? Or too much sun? I live in Texas so I thought maybe it might be too warm rn.
It looks like you have caterpillar activity. The black dots are called frass which is simply put, poop of bug larvae like caterpillars. BT is a biological control if you can't find the munching critter or if there seem to be large numbers of them. Or you can hit the plant with a blast of water to knock them off. Often damage lasts a couple of weeks and isn't significant. Cilantro likes cool conditions and it looks like you have it in a metal container. Metal heats up in the sun so much it can damage roots. You might enclose the container in aluminum foil to reflect the sun/heat. Provide cilantro with afternoon shade and consistenly moist soil to prevent it from bolting in the heat. In August, start some more for a fall crop.
