Love this product - I have never burned my plants using Osmocote and it is the perfect fertilizer for potted plants because I can't always remember to fertilize when needed.

Try it. You'll like it. November 20, 2014
When putting transplants into my container garden area [multiple half barrels]a spoon of Osmocote goes in with each plant. I use it every time.
