The Patch Perfect growing secret is its powerful fertilizer mulch cocoon that surrounds each seed, soaking up and retaining water. It’s like each seed has its own eco system, for faster, healthier germination. Remember, for each supply you order, we’ll send a second supply absolutely free. That’s enough to cover 100 square feet, at a 50% savings! With our Buy 1 Get 1 Free Offer we package your order in a single container that has double the amount. Saving on packaging helps us to keep prices low and uses less packaging material which is good for the environment. The amount of Patch Perfect seed in the container will cover 100 square feet of lawn or 200 pet urine spots when applied properly.
