Got black spots on your roses, purple spots and yellow leaves on your photinia and Indian hawthorn, brown patch in your St. Augustine grass, damping off in newly planted seedlings or algae in your pond or water feature? You don’t have to use toxic chemicals like the synthetic fungicides or heavy metal products like copper sulfate. Corn meal is an all-natural fungicide that really works!
Horticultural corn meal is a natural disease fighter that is especially good for use on fungal diseases. It’s also good to use for cleaning up algae in ponds. Don't confuse horticultural corn meal with the product sold in grocery stores. The edible variety is just the starchy inside of the corn kernel and not effective for any plant uses.
