I've grown my first garden this year of Dwarf Canna & Alstromeria, have already been invaded by whiteflies and other insects but cannot figure out what is eating large holes and even severing half of one leaf? Can anybody suggest what kinds of creatures would do this? I live in Melbourne.
Thats got to be something bigger than whiteflies Sion. My guess is caterpillars. A spray with Natures Way Dipel should get rid of them.
