If that doesn't work you can also mix 1 tsp of baking soda per gal of water.
It works on the same principal. Mildew and fungus can only live in a narrow
PH range. Changing the PH a bit, either up or down, will kill it.

BTW, the reason your shrub didn't flower last year probably doesn't have to
do with the mildew. Flowing shrubs will only flower on new growth. So if
the shrub has reached it's maximum height it will stop blooming. If this is
the case, you'll need to prune the shrub back to get it to flower again.


You are not giving the correct rate of baking soda. It's much more than that.
Like 4 tablespoons in a gallon of water.

On the flowering, there are crape myrtles all over the place where I live and
many of them are 25 feet tall and flower magnificently. I only prune out dead
wood, branches growing toward the center and anything which touches another
branch and mine flower beautifully. There will always be new growth on them
without those harsh pruning practices.
