A non-toxic, weed-and-feed with 9% nitrogen. It inhibits seed germination, but is harmless to plants with root systems, people, worms, and microorganisms. The effect can last up to 6 months and is especially useful in lawns.
“Applied in September / October, and again in late February / March it will prevent the majority of existing weed seeds from germinating. By doing this every year, you can virtually eliminate your weed problem.”
