I have been using Plant Wash for over 6 months to try to get rid of the leaf spot disease on my several Indian Hawthorne bushes. I have had limited success with the use of Plant Wash, but have been persistent in my applications of the relatively new antifungal product. Is there any value to continuing to spray my Hawthorne bushes during the cold winter months ?? Or should I wait until Spring to continue to try to irradicate the leaf spot intrusion ??

Once you have spots on the leaves, leaf wash will not take it off. You should remove those leaves.

Most fungal diseases are not that active in the winter in the south. I would take a 2 or 3-pronged approach.
1. Corn meal scattered on the ground under each affected plant, once a month.
2. Milk spray every other week.
3. Plant wash every other other week (don't spray milk and plant wash the same week).
