Update of scale problem
 

It has been 7 weeks since I started a treatment to rid scale insects from my Phal. Collection.
The Bayer tree and shrub chemical that I have been using is spot on. I have been washing the plants every 2 weeks with the solution and the scale insects are 95% or more gone.
I will continue the treatments for two more times.
Special thanks to Orchid Whisperer for the advice and web sites for information.
It was a little bit of work but I think I saved my whole collection.

good to hear!

I'm very glad I could help!

So glad you are having success.
