When I use the bayer 3 in one I never spray the plant. I mix it stronger than recommended and water. Not sure if the plant would benefit from spraying and its "gunky" when mixed more strongly. I hate cleaning leaves
The name is
Bayer Advanced All in One Rose and Flower care. It is in a huge bottle 32 oz. Blue bottle in N America... and yes indeed I got that advice from Cynthia and am ever greatful for it.
I had a problem that was severe and needed swift action. Tried Physan phyton 27 peroxide. Nothing worked. The Bayer in a higher, more frequent application worked and quite fast.
As I read the posts there is a lot of great info. I have to be honest about cinnamon. IME it is a really outdated method. The areas that are sprinkled never grow back or grow in some wierd way. I don't care how careful one is, it eventually impedes the plants progress. We have to water. It eventually gets everywhere. It never fully comes off/out. There are so many better products than an old school home remedy. Its kind of like the "chicken soup" method to me. 3% Peroxide would be better in a 1 shot straight application if you need something quick from a cabinet.
