Texas Gardening: Help Please - Variegated Pittosporum and Japanese Blueberry , 2 by Triumph65

I have a bed with variegated pittosporum, English hawthorns and a 10 foot tall (6 year old) Japanese Blueberry.
Most of the pittosporums are suffering from leaf browning that started at the tips and is traveling toward stem. One newer pittosporum is unaffected. This has been going on with the pityosporums for months.
The English Hawthorns are fine.
2nd problem is my Japanese Blueberry is suddenly wilting and dying.
I\'m in Houston. The beds did not flood.
Any help is appreciated
