Accelerate the growth of plants in your backyard with the Gro-Sure Smart Lawn seed fast start. Covered in an aqua gel coating which means they are guaranteed to grow, this technology means each seed soaks up to 400 times its weight in water which gradually releases water to the seed when needed. These seeds will also germinate in cold weather and will quickly repair any patches on your lawn whether they are in full sun or shady areas. Perfect for over-seeding worn grass or filling in bare patches. Follow the instructions on the pack.
