I planted Pittosporums six weeks ago in garden bed, Then wettest Aug in years. Signs of root rot (wilting foliage tips) so I improved drainage as much as possible (soil has clay) and sprayed Yates Anti Rot two weeks ago. Plants recovered but now two months worth of rain again in a few days in Sept.
My Q - do I need to wait 3 weeks before spraying Yates Anti Rot again - or can I do so now? Pittosporums look ok (rain only stopped yesterday) - but I’m very concerned root rot may occur again.
