Rose diesease ?? fungus problem ??
I am a newbie in delaing with roses except for the fact that i cut them in the fall to 1 feet height...a.nd then applied the Rose n feed in March 1st week of this year. I am in the Bay Area , CA. My questions are :
For some reason, there is white fungus (i think) which is developing on the leaves of the roses as well as at the bottom of the petals. Ii is not allowing the rosees to grow...What is this disease ?? How to take care of this ?? Any pesticide, etc ?? An Organic remedy will be super. I have like 5 rose plants in the front-year. How do i avoid it spreading ?? How do i avoid it completely ?
What do you use for Fertilizer for Roses. Apart from Corn Meal...what other organic fertilizer are there ?? since i am not able to find corn meal here (except for the one which is in grocery store)
