Question
I bought 4 small Hoyas in San Antonio in the 60s.  I now have about 12 or more vines trailing to the floor.  It sits in the west window.  I spritzed the plant several times and now it looks like there is some fungus on the leaves-- looks almost like white cornmeal.  Haven't seen any bugs.  Please advise.
Thank you....Debbie Davis

Answer
Hi Debra,
   Spray the affected leaves with plain old Lysol spray every day until the fungus is gone and doesn't return.

I hope this helps. If you have any questions or need additional information please don't hesitate to ask.
     Thanks
