Hollyhock Spray for Rust
Healthy Hollyhock spray (from DG'er 'stormyla')
1 1/2 tsp. baking soda
1 T. canola oil
1/2 tsp. DW soap or Murphy's Oil Soap (I used Murphy's)
1/2 cup white vinegar
Mix with 1 gal. water and spray on hollyhocks every few days. I don't do it regularly, just when I see evidence of rust starting.
