If you're merely wanting to fertilize & are already controlling any disease and/or insect problems with a spray program, then DON'T use Bayer's All-In-One soil drench. If you do use it, then suspend your spray program.

I know of no one who uses All-In-One merely for its fertilizer content. If there are folks who do, they sure shouldn't be, IMHO.

I'm encouraging you to replenish your RoseTone or replace it with another fertilizer -- whatever's on sale maybe.

Jax's advice is good. If you double up on fungicide, it will probably stunt the growth of the plant. All-in-One already does this to some extent.

This product contains the type of cheap fertilizer you can buy for 30 cents a pound in 40-lb bags.
