Our Complete Lawn Feed, Weed and Moss Killer is an all-in-one lawn treatment that nourishes grass, kills most common broad-leaved weeds and controls moss. It can be used any time between May and August when grass and weeds are actively growing to create strong and healthy grass. The 3.5kg pack will treat up to 109 square metres of an area. How to use: Wait three days after last mowing the lawn. This will allow weeds to grow and have more leaf area to absorb the weedkiller. Apply at 32gms per square metre, either by hand or with a spreader. Application: The easiest way to apply is with a spreader set to the correct spreading rate. If you wish to apply by hand, we recommend you mark out square metres on your lawn using either pegs and string or canes. Wear gloves and sprinkle the product evenly at a rate of 32gms per square metre (1oz per sq yd). Initially, spread the recommended amount over one of the squares and then use this as a visual guide for the remaining squares. Overdosing with fertiliser can damage lawns. After application leaves the weed and moss killers to work for a day without water. If it does not rain within the next couple of days, water in thoroughly to get the lawn food working. Avoid walking on the lawn until it has rained or been watered in. Keep children and pets away from treated areas until the granules have been watered in. Wait 4 days after application before mowing the lawn.
