Evergreen Complete 4-in-1 feeds your lawn to build thick green turf while actively killing lawn moss and broadleaf weeds. Includes WaterSmart technology to help lawn grass absorb water and nutrients efficiently during dry Irish summer spells. See a visibly greener lawn within 7 days, with moss turning black and weeds dying back over 3 to 5 weeks. Ideal for application between April and September using a garden spreader or by hand.
