Salvia dying stem by stem
I planted this salvia in early May.
It was in bloom when I planted it. When the flowers started to turn brown, I cut each stem with flowers a little below the lowest flower.
Now all of those stems that I cut are dead. And more leaves seem to be turning brown, stem by stem.
Did I let some disease in by cutting the stems?
I'm not sure what to do to try to save this plant, or if it's too late anyway.
