The water volume is an absolute minimum and you may find it easier to apply more water.  The key is to ensure you have applied sufficient chemical for the measured lawn area.

Re application at the lower rate above every 10 - 20 days will provide best results but as everyone's lawn area is different, you may have to re apply sooner or later than we advise.  Initially, making an application on day one and then day 11 and then day 20 will give the best results then the frequency of application will lengthen as the soil builds up a 'bank account' of the product.

Do not apply during rainfall or if rain is expected soon after application.

Mow the lawn area beforehand and keep off the lawn for 24 hours following application.  Do not mow for three days after application.

Best applied via a small compression sprayer fitted with a medium spray nozzle.  Do not use a watering can as the droplet size is all wrong and you will not get even coverage.  Follow your mowing lines and apply across the complete surface of the lawn including the corners and edges!

Please read the product label carefully and ensure that you are wearing suitable personal protective equipment like non-absorbant gloves as with other lawn treatment and care products.

If you need an effective garden sprayer, visit The Lawn Shop where they have a great range of sprayers available.

Calibration of your chosen sprayer is important!  You need to know how many square metres and litres of water your sprayer will cover and use to ensure correct calibration and results!  See Calibration of a Knapsack
