I have a Dwarf Mock Orange that is a little over a year old. It has looked really good until about 2 weeks ago when the leaves took on a little rust color and have lost all of their shine. It has been really hot this summer here in Las Vegas. Can someone shed a good reason for this discoloration?

Thanks for the reply....No white spots......I just checked......Just a slight discoloration...Not toooo bad though.........Maybe it will clear up when the weather gets a little cooler...I will just continue to water good....Maybe we will get some rain....Ha.. Not likely here in Vegas.

Your plant probably has Rust Fungus. If only a few leaves are involved remove them to the trash and clean your pruners with rubbing alcohol. Let pruners dry in the sun. If leaves of the entire plant are involved you might need a fungicide. Contact your local county extension service for a treatment program. They may recommend you spray water on the plant on a daily basis and treat with a fungicide later in the winter season when temps cool. You will need their assistance due to your special climate conditions.

One way to cut down on rust fungus is to keep garden litter cleaned up and disinfect tools. Good air circulation helps and avoid contact with the leaves if they are wet.
