Something is Killing My Plants ! Help !

I can speak from my own decades of experience that diseases can kill plants really fast. In some cases, diseases can kill a plant scary-fast. I've seen root-rotting fungi or plant-melting bacterial diseases melt big orchids in just 72 hours, in some cases even less. It seems that the disease always hits the plants on a weekend when I am out of town ! I mention this because we are approaching the "warm" weather, as they say here in Miami, which I call "beastly". It is this onset of warm weather, combined with higher night temperatures and higher humidity that will really foster disease development. It is important to recognize symptoms of disease onset and handle the situation NOW, not next week when you have a spare day or two.
Defining which disease is present is crucial to implementing a control program. The visual difference between a bacterial and a fungal pathogen may be subtle, but important; the control measu…
A Cherry Tree in Miami ?

This species goes leafless for a few weeks just bef…
