red lily beetle - did I make a mistake?
I have some tall Asiatic lilies and some shorter pixie ones right next to them. They got infested quickly with the red lily beetles and got very ratty looking with lots of their black poop on the stem. I cut them down to the ground and sprayed what was left with an insecticide like Seven. Did I make an error by cutting them down too early? Will that hurt them later? They were done blooming. They have not affected my lilies in the back garden but I keep checking! It was the same situation last year, only in the front.
