Just a little thing on Cucumbers if any body is interested. I have had trouble with Powdery Mildew at times, white sort of fluffy spots on the leaves.
I use a home made spray of Baking powder 1 Table spoon to 1 gallon of water. Well as I don't want a gallon kicking around I mix 3/8ths of a Tea spoon of Baking Powder to 1 pint. this seems to keep it at bay. I spay about once a week.
I also have read mixing milk with water at 1 part milk to 10 parts water works but I have not tried that myself.
Hope this might help.
Cheers Arry
