Re: lily beetles
Don’t pull your lilies! In April I start hand-picking the little red devils and squishing them. I know, it’s late, but I started then and seem to have got them all. No new holes in a couple of weeks.
And yes, I would try the spray regimens in those links up top — I will if I see any more visitations. How can we not grow lilies? As you say, summer wouldn’t be the same…I think it’s worth the effort. (I say this having a few big clumps, not 1000 square feet of them or anything, fyi.)
Keep us posted what happens.
