What's eating my salvias?
Can anyone identify what is eating my salvias, tithonia, helenium and many other of my herbaceous plants? Leaves have holes in them, the colour is yellowed and mottled. Some plants then grow fresh leaves with no sign of damage. What is it, can I get rid of it and can I prevent it from happening again? It doesn't seem to kill them but the plants look unsightly. Any advice please?
