squash plant leaves being eaten - abruptly - help!
I've had a zuchinni plant in a container for about six weeks now, and it has been absolutely thriving. LAst week it looked wonderful - but this week when I checked on it the leaves were drooping, some were yellow and brown and wilting, and others had large holes eaten out of them, mainly in chunks adjacent to the center "vein". I'm not sure if the fact it's being eaten is responsible for the drooping, or if a whole host of problems are afflicting my squash all at once.
There's no sign of any critters, and the container is on a rooftop and relatively segregated from other plantlife. Whatever's eating it appears to be leaving after it's done. Any ideas of what the problem could be and how to stop it? Thanks,
