I use this product in my flower beds, in the soil where and when the annuals are planted each year, and also top dressed and scratched into the surface soil around the perennials. I have been pleased with the results, and how easy and convenient it is to use. Also great for my container plants.
As in all fertilizer, pesticide, fungicide, etc. products, always follow the directions to the letter, and read the entire label for optimal results.
