Last year I had quite a bit of botrytis on my lilies. It was a very wet summer.
My lilies are now in their growth cycle from just emerging to 3 feet tall. So far our season is very dry ( 5 inches below normal)
Has anyone had experience with preventative spraying for botrytis. If so what spray did you use ?
Did you have any problems with chemical damage. At what temp did you stop using it?
botrytis
With last year being as cool and rainy as it was, lots of people had trouble with botrytis, including myself. You can use just about any fungicide, such as those that you'd use on roses. Just follow directions on the package.
Here is an article regarding Bordeaux mix and copper sulfate.
