My takeaway from that experience is that nutrition is the best way to prevent disease/pests. once there’s a problem it’s probably too late.

The plants were healthy until the bugs. The vines were growing, the leaves were huge, and they had just started to produce flowers. I've never seen the type of bugs, some stink bug type of beetle, in my yard ever before. Now that I've removed the dead plants, there's no sign of the bugs. For as many as there were, I'd expect to see some remaining. It's always a learning experience growing new plants
