Re: Baking Soda for Powdery Mildew // was: Interesting Blackspot Treatment

Carleen & list,

First of all, Oooops... I wrote 2 T (tablespoons) per gallon of water. 
That should be 3 (three)  T.  per gallon of water.  Sorry 'bout the typo.

If it were me, I'd just keep an eye on your rose.  Powdery mildew is very
easy to get rid of using the baking soda solution.  I've never had it not
work -- and quickly at that.

Usually, two applications does the trick.  I've never had to spray more
than twice, and I space the applications about two or three days apart.

Cheers,

Patty
