Gro-Sure Fast Acting Lawn Seed is a blend of quick growing, hard wearing lawn seed varieties ideal for over-seeding worn grass or filling in bare patches. The seeds are treated with Aqua Gel technology for improved germination. Aqua Gel can absorb 400 x its weight in water, and slowly releases it back to the seeds, when the seeds require it to germinate. Gro-Sure Smart Lawn Seed Fast Start Aqua Gel technology is also an excellent bird deterrent.
