How to use GroRight® Lawn Fertiliser, Weed & Moss Killer

Wait 3 days after last mowing the lawn. This will allow weeds to grow and have more leaf area to absorb the weed killer. Apply at 35gms 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 35gms 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

Leave the weed and moss killers to work for a day without watering. If it does not rain within the next couple of days, water in thoroughly to get the lawn fertiliser working. Avoid walking on the lawn until it has rained or the granules have been watered in. Keep children and pets away from treated areas until the granules have been watered in. Wait 3 days after application before mowing the lawn.

What to expect

The lawn will become a richer, greener colour within a week. The moss will blacken as it dies and can be raked out after 7-10 days. Weeds will grow vigorously at first and then become distorted and die. Maximum weed control is achieved in about 2-3 weeks. A second application may be required after 6 weeks for lawns badly infested with weeds or moss.
