Hello,
I have about five Dwarf Wheeler Pittosporum plants. All of them are mature and were doing so well. I was on vacation for a week or so and when I came back I saw of each of them is plant 90% dead. The dead leaves are crunchy and the corresponding stems are dried too. Sprinkler system was on auto run schedule during my absence. I do not see any type of infestation except very mild mealy bug dead infestation. Does anyone has same problem? Could anyone share some tips?
Thanks,
Archana
