|I am seeing what appears like grated black pepper sprinkled on my petunias and what appears to be eaten or shredded leaves. What is it and how can I eliminate the problem with a homemade remedy preferably? Thanks

|I think what you are seeing is frass (bug poop) from caterpillars feeding on your petunias. The botanical Bt (bacillus thuringensis), sold as Dipel, will take care of the critters. Or, you can hand pick them.
